The federal government will spend $700 million on building or refurbishing coal power infrastructure across the country in a boost to “clean, beautiful coal,” President Donald Trump said Thursday in the Oval Office.
Trump said he was invoking the Cold War-era Defense Production Act, which gives the president authority over domestic industry, to save 13 existing power plants and build two new ones. He said the move would save 14,000 coal jobs and lower energy costs, though the spending will not lower the price of gasoline or diesel fuel, which has spiked since Trump launched a war with Iran in February.
Trump criticized subsidies for wind power championed by Democrats, including his predecessor, Joe Biden, characterizing coal as the most important energy source to cultivate.
“It’s real power,” Trump said. “In terms of power, there’s really nothing like it. We have so many different alternatives. You talk about some, there’s no real alternative.”
New coal plants would be built in Alaska and West Virginia, Trump said. A defunct plant in Maryland would also be restarted. Those projects would be funded with $200 million in Department of Energy grants.
Coal plants receiving a combined $425 million in Defense Production Act funding are in West Virginia, Kentucky, North Carolina, Indiana, Tennessee, Arkansas, Arizona, Oklahoma, North Dakota and Wisconsin, according to the White House.
Coal mines benefiting from the move are in Pennsylvania, Kentucky, West Virginia, Ohio, Indiana, Illinois, Wyoming, North Dakota and New Mexico, according to the White House.
The administration would also spend $75 million, authorized by the Defense Production Act, to help open a long-delayed new coal export terminal in Oakland, California, the White House said.
Administration officials said Thursday’s announcement built on a record of the past 18 months in which the administration has saved dozens of coal production facilities.
“It is hard to overstate the magnitude of this,” Energy Secretary Chris Wright said. “If you look at our efforts across the whole government, so far 45 coal plants are open today that would not be open.”
Trump Cabinet members, congressional Republicans and two governors, Wyoming’s Mark Gordon and West Virginia’s Patrick Morrissey, joined Trump for the Oval Office announcement, with several extolling the importance of the coal industry after Trump spoke.
Wright, Interior Secretary Doug Burgum and Environmental Protection Agency Administrator Lee Zeldin praised Trump for intervening to help the industry and refocusing federal energy policy away from renewables.
Wright said Democratic policies were more responsible for high energy costs than the war in Iran, even though Republicans have held unified control of the federal government since January 2025 and the Trump administration has consistently touted its moves to encourage fossil fuel production.
“We wish they were lower, but gasoline prices in the U.S. are a little over $4. They’re $10 in Europe, they’re higher in Asia, they’re very high in California,” Wright said. The national average price for regular gasoline Thursday was $4.24 per gallon.
“The bigger threat to energy prices in the United States is Democratic green energy policies,” Wright continued. “They have driven up energy prices far more than a conflict in Iran.”
Burgum said the president was perhaps the strongest advocate for coal in the country’s history.
He echoed Trump’s statements that the coal industry needed to be reinvigorated after the Biden administration focused more on renewable energy production.
“The prior administration, under Biden, had gone so far down the path of pursuing the highly subsidized, intermittent, weather-dependent sources of electricity that our grid was at risk. You understood that and you understood how key coal is,” Burgum told Trump. “It’s the backbone of having affordable, reliable and secure American energy to power our country, our electric grid, power our competitiveness in AI, and power all the manufacturing that’s coming back.”
Morrissey said the moves would benefit his state.
“We believe your policies are going to allow America to compete and win,” Morrissey said. “West Virginia is going to supply the coal, the gas, the nuclear to help make that happen. So I’m very excited by everything you’re doing.”
Environmental groups blasted the move, saying it propped up a failing industry and would have little long-term impact on energy prices or reliability.
Jesse Lee, a senior adviser with the advocacy group Climate Power, said the spending on coal projects would not lower utility prices, which he said have climbed 18% during Trump’s second term.
“He’s gaslighting the American people by claiming that this move will lower electricity prices in the middle of an energy affordability crisis that he created,” Lee said.
Environmental groups noted the coal industry heavily contributed to Trump’s 2024 campaign.
Several environmental advocates, including Lena Moffitt, the executive director of the climate group Evergreen Action, suggested that relationship drove Trump to promote coal at the expense of renewable energy sources.
“Spending $700 million to bail out the coal industry is like throwing a lifeline to a ship that has already sunk,” Moffitt wrote. “Trump is handing out taxpayer money to coal barons and leaving us with nothing but higher energy costs. … There’s no coal revival waiting around the corner—just polluters collecting a handout while their friends run the White House and Americans foot the bill.”

The world’s largest meat and dairy companies, many of which operate in Wisconsin, have made hundreds of claims that their practices are sustainable and promises of future climate protection initiatives. But a report released last month in the journal PLOS Climate found that hardly any of those claims are legitimate.
The report, authored by researchers at the University of Miami, assessed publicly made environmental claims and promises of the 33 largest meat and dairy companies in the world. The corporations assessed in the report includes companies with Wisconsin operations such as Saputo Cheese, Tyson Foods, JBS, Hormel Foods, Dairy Farmers of America and Nestle.
Since 2021, the corporations made 1,233 environmental claims but, according to the report, 98% of those claims can be called “greenwashing” because they were made without supporting evidence. Only three of the claims were backed with actual peer reviewed studies.
“This study is consistent with what we have experienced: big claims, big promises, but little in the way of quantifiable improvement in environmental quality,” said George Kraft, the former Director of the Center for Watershed Science and Education at UW-Extension and UW-Stevens Point who now sits on the science council of Wisconsin’s Greenfire.
The report’s authors argue that it’s important to assess the claims of these companies because corporate meat and dairy operations cause a huge proportion of global greenhouse gas emissions.
“Meat and dairy companies, which produce disproportionate amounts of pollution relative to other kinds of foods, have prioritized climate change in their sustainability initiatives,” the report states. “They make many promises and provide very little supporting evidence. Like the fossil fuel industry, which has used greenwashing over the last several decades to delay meaningful climate action, the meat and dairy industry may be misleading consumers and investors regarding whether and to what extent they are addressing environmental impacts, including climate change, with even less time to spare.”
In Wisconsin, economic forces have for decades pushed the state’s dairy industry to get bigger. Hundreds of factory dairy farms are now permitted to operate in the state, putting more cows on more concentrated plots of land while the state’s corporate dairy interests fight at the local and state level to prevent government regulation.
Tara Greiman, the Wisconsin Farmers Union’s director of conservation and stewardship, told the Wisconsin Examiner that corporate agriculture has been the dominant force in the industry for the last 50 years and the effect of that control on the environment is clear.
“They can say as much as they want, ‘look at all of our promises, look at what good stewards we are,’ but the fact of the matter is that our groundwater quality is depleting in the sectors that they control, our ecological habitat diversity depleting, we are losing farmers at the same time,” she said. “There’s other economic factors, but speaking in terms of just the climate measurements, they’re not doing a good job.”
Earlier this month, the environmental organization Clean Wisconsin released a report outlining the steps Wisconsin’s agricultural industry will need to take to help the state achieve its climate emissions goals. The research found that reducing nitrogen fertilizer use, reducing the amount of acreage used for corn-based ethanol production, practices such as no-till and cover crops, better livestock management and the planting of perennials instead of commodity crops would help put Wisconsin on the right track.
Chelsea Chandler, Clean Wisconsin’s climate, energy and air program director, told the Examiner the fact that corporate agribusiness feels the need to make sustainability claims is a first step. She said that sometimes companies are intentionally “overstating the benefits” of a practice, lack enough data or are extrapolating too much across different parts of the world. Still, the discussion can lead to helpful action and the adoption of scientifically backed solutions.
Clean Wisconsin’s climate solutions roadmap can help, Chandler said, “because it’s based on the latest science, it’s tailored specifically to Wisconsin, and it’s checking some of those claims that are overstated when it comes to the climate impacts.”
Chandler hopes that providing good information will affect investment and support, “whether that’s coming from private companies who are trying to improve their sustainability in their operations, or if that’s coming from governments through different kinds of incentive mechanisms and channeling those into the things that are really having an impact”
Both Chandler and Greiman said that deliberate choices built the food system we have today and it will take deliberate choices to build something more sustainable.
“We need a new food system. Growing corn, even if you’re doing no-till, even if you’re cover-cropping after it, if you’re only growing corn and soybeans, it’s not a regenerative system. Full stop,” Greiman said. “We have to have new markets, otherwise we’re just rearranging deck chairs, and the research is saying this.”

Desperate to get a handle on rising property insurance costs driven by natural disasters, some state lawmakers are opening up a new line of attack in the effort to force oil companies to bear the cost of climate change effects.
In three states, Democratic lawmakers introduced bills this session that would allow insurance companies or state attorneys general to take action against oil companies to offset the rising costs of insurance.
While none of the measures became law this session, they signal the increasing urgency in states where wildfires, floods and other disasters have driven up the cost of insurance premiums and led some insurers to stop writing new policies.
The proposals follow other state-led efforts to demand payment from fossil fuel producers for the mounting damages caused by climate change. States and municipalities have filed more than three dozen lawsuits over the industry’s role in the climate crisis, claiming companies violated a variety of laws, including consumer protection, public nuisance, failure to warn, fraud and racketeering.
Meanwhile, a handful of states have passed or introduced “climate Superfund” bills that use attribution science — a new field of research — to calculate the cost of disasters and charge fossil fuel companies for their role in causing them.
Those efforts have drawn fierce opposition and legal challenges from oil companies and conservative groups.
Now, some Democrats are using a similar premise to try to put large oil companies on the hook for the fast-growing insurance crisis.
In many states, property insurance costs have skyrocketed as insurance companies have paid out increasing claims for wildfires, hurricanes and floods. Some insurers have stopped writing policies in certain areas.
California and some other places have seen a surge of new policies on state-backed “last resort” insurance plans after residents failed to find coverage on the private market. California’s program, known as the FAIR Plan, was hit with billions in losses and sought a massive rate hike following the Los Angeles wildfires in 2025.
A bill in California would empower the state attorney general to sue fossil fuel companies to recover insurance costs. That measure failed to advance out of committee last month, with Republicans and some Democrats expressing concerns about fuel prices among other issues.
A bill in Hawaii would allow insurance companies to seek damages from fossil fuel companies for their role in causing disasters worsened by climate change. Any proceeds gathered from actions against polluters would be factored into insurance rates.
The bill passed both the House and Senate, but failed to advance when a conference committee ran out of time before a deadline earlier this month, the Honolulu Star-Advertiser reported.
“[T]he largest oil and gas corporations, who knowingly contributed to the drought conditions that made the Maui fires worse, pay nothing while continuing to rake in billions of dollars in profit every year,” Democratic state Sen. Jarrett Keohokalole wrote in a Honolulu Civil Beat op-ed. “Hawaiʻi taxpayers should not be forced to foot the bill for Big Oil’s deception.”
Meanwhile, a similar bill in New York, allowing both insurance companies and the state attorney general to take action against oil companies over insurance costs, has been introduced but has not yet had a hearing in committee.
As with all legislation targeting the fossil fuel industry, the insurance bills have encountered fierce opposition and powerful lobbying campaigns. If enacted, the proposals would undoubtedly face lawsuits. Fossil fuel companies have long argued that they extracted and sold their products while following a suite of federal regulations, insulating them from state claims of harm.
States have countered that the companies knew about the dangers of climate change but lied to the public, noting the successful campaign to hold tobacco companies accountable for deception even though their products were sold legally.

Despite regional variability in climate, electricity sources, congestion, and the wide variation in individual driving patterns, electric vehicles generate less greenhouse gas emissions and do not cost more than comparable gas-powered vehicles for drivers and vehicle fleet owners in most parts of the United States, according to a new study by MIT researchers.
The team’s approach captures many key factors that contribute to regional and individual differences in the life-cycle emissions and ownership cost of electric vehicles, including meteorological data, the distance and duration of trips, and fuel prices.
To paint a fuller picture of emissions and costs than was previously available, the researchers sourced data from thousands of U.S. zip codes and drilled down to the level of individual drivers within those locations. Their study considers time-averaged fuel prices so as not to be overly influenced by fluctuations in prices at any one point in time. They finalized their analysis at the end of 2024 and early 2025.
Their results indicate that a person’s driving behaviors can matter as much as regional factors like the local electricity mix when it comes to the emissions savings of an electric vehicle, compared to a similar gas-powered vehicle. In most locations, a battery-electric vehicle reduces emissions between 40 and 60 percent, with larger impacts in urban areas.
They also found that colder climates do not reduce overall emission benefits as much as some media reports assume.
The researchers utilized this detailed analysis to update a public tool they previously developed, carboncounter.com, which enables individuals to compare the life-cycle emissions and total ownership costs of nearly any car on the market. A new version of carboncounter.com is also being released today.
“There are a lot of statements being thrown around, like that electric vehicles don’t reduce emissions very much in cool climates, and we wanted to analyze these factors systematically and evaluate these statements against one another simultaneously. Rather than simply asking, ‘Are EVs better?’, this paper helps answer ‘better for whom, and under what conditions?’” says Marco Miotti PhD ’20, a senior researcher at ETH Zurich who completed this research while a graduate student in the Institute for Data, Systems, and Society (IDSS) at MIT.
He is joined on the paper by senior author Jessika Trancik, a professor in IDSS. The research appears today in Environmental Research Letters.
A holistic approach
Many prior studies that compare emissions and costs of electric vehicles (EVs) to combustion-engine vehicles cover a few factors, like the amount of renewable energy in the grid and how gas prices impact affordability, Miotti says.
“To our knowledge, there have been few efforts so far that bring all these factors together. But if someone wants to buy a car and have a better understanding of the factors that affect emissions and costs, this holistic approach is important,” he adds.
The researchers focused on two types of EVs: battery-electric vehicles, which only operate on electricity, and plug-in hybrid electric vehicles, which also have a combustion engine that works in tandem with the battery to optimize fuel savings.
The team expanded and improved a set of previously developed vehicle cost and emissions models to incorporate a wider variety of factors and data types.
For instance, they refined an existing model that estimates energy use and gas mileage so it could capture more nuances of local climate variability.
“But the real effort was not just in extending these different models, but in bringing together all these different data and making them work with the models in a consistent manner,” Miotti says.
The team sourced data on a wide variety of factors for each U.S. zip code, such as typical drive cycles, the amount of traffic, local gas and electricity prices, makeup of the regional electricity mix, meteorological profiles, and more. They used statistical approaches to amalgamate different types of data.
For example, the team used a probabilistic matching technique to combine data on how often people drive, which was drawn from nationwide travel surveys, with more detailed GPS data that includes factors like drivers’ acceleration patterns and the distance they usually drive on each day of the week.
The researchers designed their analysis to focus on the spatial picture of emissions and costs, based on U.S. zip codes, while simultaneously considering the impact of the size and features of each specific vehicle model.
“At the end of the day, it’s the vehicle and fleet owners who make decisions about vehicle purchases. So, we wanted to make sure to consider their wide-ranging individual perspectives rather than simply performing a region-by-region comparison,” says Trancik.
Lower emissions, comparable costs
In the end, their modeling framework revealed that all factors they analyzed matter about equally in determining emissions-reduction potential of EVs compared to internal combustion vehicles.
EVs reduce emissions the most in areas with a cleaner electricity mix, denser traffic, higher annual travel distances, and a mild climate, in decreasing order of importance. In each area, emission reductions increase for drivers who drive more often, drive larger vehicles, and are more frequently stuck in traffic.
In a colder area like North Dakota, fuel economy of battery-electric vehicles might be reduced by as much as 50 percent on a particularly frigid night, but the effect on annual emission benefits is minimal.
“We even did a sensitivity study to see if the range is reduced in very cold climates, and we found that, even in the most unfavorable conditions, EVs still reduce emissions by a substantial amount,” Miotti says.
On the cost side, the models show that, in most places across the U.S., EVs are competitive with comparable combustion-engine vehicles in terms of lifetime ownership cost, even without clean vehicle tax credits. And in areas where electricity is relatively affordable, battery-electric vehicles tend to cost less than their plug-in hybrid or combustion-engine counterparts.
In the future, the researchers want to expand this analysis to include a temporal dimension, so the framework also considers how changes in vehicle, fuel, and electricity prices affect emissions and costs over time.
“While we found that the electricity mix is a big driver of the spatial variation in emissions savings of EVs, the electricity grid is decarbonizing everywhere. As that happens, emissions savings across space will become more homogenous for EVs, but the differences across one driver to another will remain,” Miotti says.
They could also use the framework to explore regions outside the United States or incorporate data on hybrid-electric vehicles that cannot be plugged in.

A Dane County judge dismissed a lawsuit from 15 Wisconsin children who had challenged laws they argued made climate change worse and violated their constitutional rights.
The lawsuit was filed in August by the groups Our Children’s Trust and Midwest Environmental Advocates against the state Public Service Commission and Legislature.
The suit argued that state lawmakers have made a number of declarations that the state’s energy production should be decarbonized and the greenhouse gas emissions of that production should be reduced, but state laws prevent that from happening.
The state’s law for siting power plants requires that the state Public Service Commission determine that “[t]he proposed facility will not have undue adverse impact on other environmental values such as, but not limited to, ecological balance, public health and welfare, historic sites, geological formations, the aesthetics of land and water and recreational use.” However the law also prohibits the PSC from considering air pollution, including from greenhouse gas emissions, in that determination.
Additionally, the state set a goal in 2005 that 10% of Wisconsin’s energy come from renewable sources by 2015. That goal was met in 2013. However, now that the goal has been met, state law treats it as a ceiling on renewable energy the PSC can require.
In a decision issued last week, Judge Julie Genovese said she’s sympathetic to the children’s argument but that the lawsuit was asking her to weigh in on a fundamentally political, not legal, question.
“While the court is sympathetic to the youths and admires their willingness to access the courts in their quest to protect the planet, I conclude that the case must be dismissed because environmental policy is a nonjusticiable political question,” she wrote.
Attorneys for the Legislature had also argued that the children didn’t have standing to bring the case, pointing to a federal court decision in a similar case in California.
But in other states similar cases have had more success. A group of Montana children successfully sued to protect their right to a clean environment in 2024.
Tony Wilkin Gibart, MEA’s executive director, told Wisconsin Public Radio he believes there’s a strong case for the ruling to be appealed.
“Youth plaintiffs are frustrated,” he said. “They’re also incredibly determined and have expressed a lot of resolve to continue this fight.”

Bailey Magers and Sunil Kumar cut strange figures on Pensacola Beach. Bags of disinfectant solution surrounded them on the white sand; their gloved hands juggled test tubes while layers of rubber and plastic shielded their skin from the elements. As the two organized their seawater samples on the popular Florida beach last August, an older woman wearing a swimsuit walked over to ask what they were doing.
“We’re just actively monitoring water quality,” they told her, but she pressed on.
“Are you looking for that flesh-eating bacteria?”
“We’re looking into it,” they replied, hoping not to frighten her. The woman turned back toward the ocean, her curiosity satisfied. As she walked away, Kumar noticed that she had scrapes and bruises on her body. A few minutes later, he watched her step into the waves. He shook off a chill and returned to the task at hand.
Magers and Kumar study a bacteria called Vibrio, part of a lineage of ancient marine species that likely emerged sometime around the Paleozoic Era. Enormous, shallow seas flooded the massive, interconnected supercontinents that constituted the Earth’s landmass at the time, and complex marine ecosystems developed that thrived in these temperate, freshly-formed bodies of water. Researchers think there are more than 70 Vibrio species in the environment today, hundreds of millions of years later. The organisms float in warm, brackish water, attaching themselves to plankton and algae and accumulating in prolific water-filtering species like clams and oysters.
A small number of Vibrio species can sicken and even kill. In worst-case scenarios, a person who has been exposed to the most dangerous of them — by swimming in brackish water with an open wound or ingesting a piece of raw shellfish that is contaminated with the tasteless and odorless toxin — may find themselves with only hours before the flesh on one or more extremities starts to bruise, swell, and decay. Without the quick aid of powerful antibiotics, septic shock can set in and lead to death. Anyone can get infected, though it is much more likely in people who have liver disease or are immunocompromised, elderly, or diabetic.
Climate change is making the world’s oceans, which have absorbed more than 90 percent of the excess heat trapped by greenhouse gas emissions, more hospitable to Vibrio. Research shows that temperature and salinity are the largest predictors of how widespread Vibrio bacteria are. As water temperatures rise, so does the concentration of Vibrio in seawater — boosting the risk of infection for beachgoers and shellfish consumers. The bacteria start getting active in water temperatures above 60 degrees Fahrenheit and multiply rapidly as coastal waters warm throughout the summer. In recent years, scientists have documented Vibrio expanding into places that were once too cold to support the bacteria, pushing as far north along the U.S. East Coast as Maine and appearing with more prevalence in temperate seas around the world.
Vibriosis infections in general are the leading cause of shellfish-related illness in the U.S. They have increased “more than any other illness caused by a pathogen in the U.S. food supply” since the Centers for Disease Control and Prevention, or CDC, started keeping tabs on such illnesses in 1996, according to a 2019 analysis by the International Association for Food Protection. The report attributed the precipitous rise to a “perfect storm” of factors that include climate change, food handling practices, expanding globalization, a patchwork of regulatory oversight, and improved diagnosis.
On their conspicuous expeditions to Pensacola and other Sunshine State beaches, Magers and Kumar are trying to understand where, and when, harmful Vibrio species are present across the state. The research they’re doing is part of an ongoing effort by a laboratory at the University of Florida to create a Vibrio early warning system for the eastern United States — a program that can alert public health departments to high Vibrio concentrations in any given area a month in advance. How many limbs would be saved, Magers wonders, if doctors and nurses could be warned ahead of time that their emergency rooms would soon see an uptick in these chronically underdiagnosed infections?
The work serves more than one purpose: As Vibrio bacteria spread north into cooler waters, they serve as a first warning signal of changing marine conditions — giving researchers a heads-up that the familiar composition of marine species in their local waters may be starting to shift. In Europe’s Baltic Sea, for example, a spike in Vibrio infections in July 2014 closely mirrored a heatwave that rapidly warmed the shallow sea. The incident showed researchers that Vibrio spikes herald unusually warm marine conditions — and they have since been utilized as barometers for ocean heatwaves and sea-surface warming patterns, not just food safety.
“We see Vibrio as the indicator for climate change,” said Kyle Brumfield, a microbiologist at the University of Maryland who has been studying the bacteria for a decade. “We can use the presence of Vibrio and Vibrio cases as a proxy for water health in general.”
The CDC estimates that about 80,000 cases of vibriosis occur in the U.S. every year, resulting in about 100 deaths. Of those 80,000 cases, most are caused by a Vibrio called parahaemolyticus, which most commonly results in gastroenteritis, or food poisoning. The vast majority of the deaths, however, are caused by a type of Vibrio called vulnificus — the Latin word for “wound-making.”
Vulnificus is so potent it can squeeze through a pinhole-sized cut in the skin and lead to death in just 24 hours. In the last five years, the CDC registered 429 such vulnificus cases, plus 136 foodborne cases. But even though foodborne cases are less numerous, the patients that contract vulnificus by eating contaminated shellfish are more likely to die than those infected via open wounds. Thirteen percent of those nonfoodborne cases died, compared to 32 percent of people who got the infection from eating seafood. Most cases occur in the Gulf and Atlantic coastal regions.
As far as infectious diseases go, vulnificus is exceedingly rare: The CDC reports between 150 and 200 cases a year. The sexually-transmitted disease chlamydia, by comparison, one of the most common bacterial infections in the U.S., infects northward of 1.5 million Americans annually. But vulnificus’ astonishing speed and high fatality rate — 15 to 50 percent, depending on the health of the person exposed and the route of infection — makes it a unique public health threat, particularly as climate change grows its pathways of exposure.
Vulnificus is not the kind of pathogen you’d want behaving erratically, but that’s exactly what it’s been doing since the late 2010s. Across the Eastern Seaboard, local and federal health officials have been reporting “unusual increases” in vulnificus prevalence — jagged spikes in infections that appear to correspond to extreme weather events like hurricanes and marine heatwaves.
In 2022 and 2024, years when the brackish water that Vibrio bacteria thrive in was pushed inland by major hurricanes, Florida’s public health department reported 17 and 19 deaths, respectively, linked to vulnificus exposure via open wounds. North Carolina, New York, and Connecticut also saw small clusters of infections during a record-breaking heatwave in the summer of 2023. “As coastal water temperatures increase,” the CDC warned in its investigation of those outbreaks, “V. vulnificus infections are expected to become more common.”
A 2023 study that analyzed a 30-year database of confirmed vulnificus infections from outdoor recreation along the U.S. Gulf and Atlantic coasts found the northern boundary of infections has moved north by a rate of 30 miles per year since 1998. The study noted that “V. vulnificus infections may expand their current range to encompass major population centers around New York,” and that annual case numbers may double as temperatures rise and America’s elderly population grows.
“In the 1980s, Vibrio abundance would increase in the late spring and stay high through the summer and drop in the middle of October,” Brumfield, who conducts research on Vibrio in Maryland, said. “Now … we can pretty much find them almost year-round.”
Just how worried we should be about the changing dynamics of Vibrio bacteria depends on who you ask and what you read. The gruesome and fast-acting nature of the vulnificus infection makes it enticing fodder for local and national news media, fueling a spree of terrifying reports every time a new severe infection or death surfaces. “Virginia dad wades in calf-high water, dies 2 weeks later of flesh-eating bacteria that ‘ravaged’ his legs,” read a recent headline in People magazine. “2 dead after eating oysters, contracting flesh-eating bacteria, officials say,” per a 2025 web story about two deaths linked to oyster consumption in Louisiana and Florida. Like many others in their mold, neither story mentions how rare the bacteria are.
The press is bad news for some in the seafood industry, which does not welcome a national conversation about the rise in vibriosis cases, vulnificus in particular. Shellfish farmers and industry representatives that Grist spoke to in Florida and New York argued media attention on the safety of their products is unwarranted. “‘Flesh-eating bacteria,’” said Leslie Sturmer, a researcher who works for the University of Florida’s shellfish aquaculture extension program and consults with the shellfish industry on research and regulation — “the media loves it.”
Paul McCormick, an oyster farmer in Long Island who sells 750,000 oysters a year, thinks all press is bad press. “Even if the title of your article says ‘New York oysters are the safest oysters in the universe,’” he told me on the phone from his office in East Moriches in January, “you’ve already created a problem.”
In unrefrigerated oysters left out in warm conditions, Vibrio bacteria reproduce every 20 minutes. But in 2010, states began deploying strict protocols known as “Vibrio control plans,” which require harvesters to rapidly cool their catch onboard and then refrigerate it at a shellfish processing facility within a set number of hours. The measures have proven effective at stopping the growth of Vibrio in harvested shellfish and preventing disease.
The fact that infections can happen in one of two ways — shellfish consumption and seawater exposure — makes it easy to shift blame and point fingers. Consumers have more control over how much exposure they have to Vibrio than they have with E. coli, for example. A person with a kidney condition can choose not to eat oysters on the half shell. E. Coli, often found in raw vegetables, is far tricker to avoid. Likewise, someone with an open wound can opt not to bathe in brackish waters if they are aware of the risks lurking in the surf.
For shellfish industry representatives, personal responsibility is the primary way to bring caseloads down. “The person is the risk,” said Sturmer. “Not the climate, not the water, not the bacteria.” Implicitly, this appears to be the government’s position as well: There is currently no numerical threshold at which state public health agencies will “shut down” a beach for outdoor recreation, though states will issue public advisories and, very rarely, close beaches if they happen to find high levels of Vibrio in the water.
But that perspective doesn’t account for the rapid marine changes brought on by climate change, the patchiness of vibriosis awareness, and the fact that Americans often make personal decisions that are at odds with their own health and safety.
The shellfishers Grist spoke to fully acknowledged the research underpinning Vibrio’s spread. McCormick studied environmental science in college, and Sturmer is running her own climate experiments in a laboratory in the fishing town of Cedar Key, Florida, putting different kinds of clams and oysters through heat stress tests to determine which species are best equipped to weather the decades ahead. Marine mollusks are uniquely threatened by rising ocean temperatures, ocean acidification, and sea level rise, issues that can lead to thin shells, low crop yields, and mass die-offs on farms. A detailed understanding of climate science, in other words, is good business for those who make their living fishing.
The problem, according to Sturmer, is that shellfishers have been unfairly singled out for a health issue that doesn’t affect most consumers and is more often contracted by ocean bathing rather than raw oyster consumption. While beaches stay open even when Vibrio bacteria are present in the water and lead to infections, a small number of foodborne vibriosis cases can trigger state closures of shellfish harvesting areas and product recalls. The National Centers for Coastal Ocean Science noted that these precautions “erode consumer confidence and likely decrease sales.”
The panic that ensues after media reports of Vibrio infections has a similar effect: A 2024 study asked more than 350 shellfish consumers in Rhode Island — a state that relies heavily on its shellfish industry, particularly in summer months when people vacation along the coastline — to bid on entrees of raw oysters and clams. After showing study participants a real newspaper article about a 2015 Vibrio outbreak linked to an oyster farm in Massachusetts, the researchers reported that the news had a “significant negative impact” on participants’ willingness to bid on oysters. It had a depressive effect on clam sales, too.
“You should really be out there beating the drum on botulism or salmonella or E. Coli,” Sturmer told me on a recent visit to her lab in Cedar Key. “Why worry about [vulnificus] when the number of cases are so minimal?” Sturmer is quick to point out that even the term “flesh-eating bacteria” is a misnomer. She’s right, in a sense: The bacteria doesn’t “eat” tissue; it destroys it. But it’s hard to say whether someone who has survived a bout of necrotizing fasciitis, the medical term for what vulnificus does to the flesh, would care to dispute the difference.
Protecting consumers from being sickened by the deadly bacteria isn’t as simple as trusting people with underlying medical conditions not to eat shellfish. Americans consume 2.5 billion oysters every year, half of which are eaten raw. Vibrio infections, which most often resemble food poisoning, are still underreported and underrecognized, even among individuals who are most at risk of developing a severe infection. Vulnificus infections are also underreported, but much less so than other Vibrio-related infections because they often require a hospital or emergency room visit.
“I’ve cared for many people with salmonella infections and water-borne infectious processes, but this is the one that is likely the most serious,” said Norman Beatty, an associate professor at the University of Florida College of Medicine who is also a practicing infectious disease doctor in Gainesville, and has seen limbs and lives lost to vulnificus.
When it comes to preventing Vibrio infections, the work Magers and Kumar are doing could take some of the onus off of individual responsibility. The researchers are identifying which parts of the eastern U.S. coastline will be most risky for overall vibriosis infections, and vulnificus specifically, as waters warm. Alongside a group of microbiologists from the University of Maryland, including Brumfield, the scientists have developed a computer model that can predict how high the vibriosis risk will be in any given coastal county on the Gulf or East coasts a month in advance. The team trained their model by pairing the CDC’s count of Vibrio-related foodborne and waterborne illnesses from 1997 to 2019 with satellite data that measures the conditions that fuel Vibrio growth, such as water temperature and salinity.
The system is far from perfect. When the model was first trained and evaluated, it was only 23 percent precise in pinpointing high-risk counties, meaning just one in four of the counties the program labeled as high-risk actually ended up seeing a vibriosis case in a given month. But it was very good at determining which counties were low-risk, capturing those regions with 99 percent precision. And it improved over time as the quality of the data they fed it got better. When they had the model do a test run on data collected by the Florida Department of Public Health from 2020 to 2024, 72 percent of total cases occurred in counties the tool flagged as high-risk for vibriosis.
Perhaps most significantly, the model was especially adept at predicting high-risk counties ahead of Hurricanes Helene and Milton in 2024 — more than 80 percent of the vibriosis cases that occurred in Florida in the aftermath of those hurricanes were reported in counties the model had already flagged as high-risk.
The tool is geared toward predicting water-borne infections, but it may also provide useful information to the shellfishing industry, though the system isn’t a replacement for the established protocols farmers already use — protocols that have proven to be effective, particularly in states that are aggressive about enforcing them. What the new tool could do, however, is supplement those Vibrio control plans, especially when an upcoming weather pattern deviates from the historical norm — something that has been happening a lot lately.
States currently use a rolling five-year average illness rate to calculate how many minutes or hours harvested shellfish can stay on a boat before moving into indoor refrigeration. In February, for example, Florida shellfishers have to get their oysters into refrigeration by 5 p.m. on the day of harvest. In July, they have no more than two hours, or they have to cool their catch in ice slurries on board. But these timetables don’t account for sudden temperature anomalies.
“It’s going to be 80 degrees this week in Alabama,” Andy DePaola, a Gulf Coast oyster farmer, told me in February. “Yet I can keep my oysters out for, like, 14 hours, because the rolling five-year average is 20 degrees less than that anomaly.” (DePaola is also a microbiologist who worked on Vibrio at the FDA for the better part of 40 years, and is the author of the 2019 analysis that diagnosed the “perfect storm” for Vibrio spread.)
But the shellfish industry doesn’t appear enthusiastic about the idea of assigning counties a risk category based on Vibrio prevalence. Vibrio researchers, by their own admission, haven’t done a good job of reaching out to shellfishers to find out how such a tool would work best for them. At an August meeting of the Delaware Bay Section of the New Jersey Shellfisheries Council last year, the director of a shellfish research laboratory brought up the idea of using Vibrio predictive models to “determine optimal days to harvest to reduce the transfer of infection to humans.” A lengthy discussion ensued. The consensus, ultimately, was that the model was a bad idea, and could be “used against the industry.”
Not all shellfishers are dead set against the kind of work Magers and Kumar are doing. “If Vibrio is an indicator of global warming, then that’s just an unfortunate bad luck scene for us,” McCormick, the Long Island oysterman, said. But it’s hard for him to see what relevance that research has to an industry that already has its own methods of controlling Vibrio. “In my mind that exists in one realm and the safety of our oysters is a whole different thing.”
As we move deeper into the 21st century, however, those two realms will have more overlap. If countries keep up their current pace of greenhouse gas emissions, most coastal communities along the East Coast will be environmentally primed for vibriosis outbreaks during peak summer months by midcentury. It won’t be a question of if there will be more vibriosis cases — it will be a matter of how to manage them. That’s the scenario Magers and Kumar are preparing for.
“In 30, 40, 100 years, these models won’t even matter because the risk is so high,” said Magers, the lead author of the predictive modeling study. “When it gets to that point, it would probably be a different kind of modeling strategy where we’d be modeling case numbers instead of infection risk.”

What is Vibrio?
Vibrio is a type of bacteria that has been around for hundreds of millions of years; researchers have identified more than 70 species. These species are mostly harmless, but some can cause infection. The bacteria thrive in warm, brackish (slightly salty) water such as estuaries and bays, attaching themselves to plankton and algae and accumulating in prolific water-filtering species like clams and oysters. Serious infections typically happen either through exposure to an open wound in saltwater or, more rarely, ingestion of raw shellfish that contain the bacteria.
The concentration of Vibrio in coastal waterways is higher from May through October, when temperatures are warmer. Most U.S. cases are in the Gulf and Atlantic coastal regions. Vibrio is tasteless and odorless. The Centers for Disease Control and Prevention, or CDC, estimates that about 80,000 cases of vibriosis (an infection caused by the Vibrio bacteria) occur in the U.S. every year, resulting in about 100 deaths. Florida has the highest number of cases, with about 20 percent reported from the Indian River Lagoon region, a popular recreation destination on the Atlantic Coast.
What happens if you come into contact with Vibrio?
Most people are not at risk of developing illness, or they may have only mild symptoms. However, those with compromised immune systems can develop life-threatening infections.
The majority of the 80,000 annual U.S. cases are caused by a Vibrio called parahaemolyticus, which most often infects people via the raw seafood they eat and usually leads to gastroenteritis, or food poisoning. The symptoms may include nausea, vomiting, diarrhea, stomach cramps, fever and chills, weakness, fatigue, and headache.
A different type of Vibrio, vulnificus, is much less common, but can cause severe illness. The infected wound may be red, swollen, and painful, or you may develop mild gastrointestinal issues such as watery diarrhea, stomach cramps, or vomiting. Symptoms typically appear within 12 to 24 hours and can last up to seven days. Healthy people tend to fight off the infection on their own. But if flesh on one or more extremities to bruise, swell, and decay, or symptoms of sepsis occur, it is a medical emergency. Vulnificus can squeeze through a pinhole-sized cut in the skin and lead to death in just 24 hours. This severe infection is rare, but it has a 15 to 50 percent fatality rate; the vast majority of the 100 annual deaths are from this strain. A severe vulnificus infection is much more likely in people who have liver disease or are immunocompromised, elderly, or diabetic.
How concerned should I be — and how do I stay safe?
You don’t necessarily need to avoid oyster bars or cancel your beach trip, but you should know how to stay informed and take precautions. Here are a few ways to do so:
How is climate change affecting Vibrio?
Climate change is making the world’s oceans, which have absorbed more than 90 percent of the excess heat trapped by greenhouse gas emissions, more hospitable to Vibrio. The bacteria start getting active in temperatures above 60 degrees Fahrenheit and multiply rapidly as waters warm throughout the summer. Vibrio is expanding into places that were once too cold to support it, farther north on the U.S. East coast and in other temperate seas around the world. As it spreads, it serves as a first warning signal of changing marine conditions.
What’s being done to address Vibrio?
There’s a lot of research happening to better understand the risks these bacteria pose under changing environmental conditions: A group of microbiologists at the University of Maryland, alongside other scientists, have developed a computer model that can predict how high the risk of vibriosis will be in any given coastal county in the eastern U.S. a month in advance. The team trained its model, which is still under development, by pairing the CDC’s count of Vibrio-related foodborne and waterborne illnesses from 1997 to 2019 with satellite data that measures the conditions that fuel Vibrio growth, such as water temperature and salinity. It’s far from perfect, but it’s improving. And it was especially adept at predicting high-risk counties ahead of hurricanes Helene and Milton in 2024 — more than 80 percent of the vibriosis cases that occurred in Florida in the aftermath of those hurricanes were reported in counties the model had already flagged as high-risk.

Earth Day 2026 arrives less than a week after Wisconsin was battered by a succession of unseasonably severe thunderstorms, hail and tornadoes. A lack of snow in the West this winter has raised fears of an especially difficult wildfire season — raising air quality concerns across the Upper Midwest this summer. The administration of President Donald Trump has made drastic changes to the budget and structure of agencies such as the EPA and U.S. Forest Service, reducing staff at agencies that manage air and water quality and protect public lands.
Nearly 60 years after Earth Day was founded by Wisconsin Gov. Gaylord Nelson, environmental advocates and elected officials celebrated the holiday noting the state, often labeled a “climate haven” for its easy access to fresh water and northern location, is not immune from the damaging effects of climate change. Still, they said, there are small victories happening every day across the state.
Gov. Tony Evers spent the week on a statewide tour touting efforts to plant more trees, conserve more land and use more sustainable sources of energy.
In 2021, Evers signed a pledge that Wisconsin would plant 75 million trees and conserve 125,000 acres of forestland by the end of 2030. In a Tuesday news release, Evers’ office announced that in 2025 the state planted nearly 12 million trees and conserved more than 7,800 acres of forestland in the state in 2025 — bringing the total to more than 54 million trees planted in five years.
“Conservation and protecting our natural resources are core to who we are as a people and as a state — it’s in our DNA, and here in Wisconsin, our work to conserve and protect our lands, waters, and air and respond to an ever-changing climate has never been more important,” Evers said in a statement. “From flooding and severe weather events to unseasonable snow droughts and everything in between, it’s clear that climate change is an imminent threat to our state, economy, and our kids’ future. That’s why, since Day One, my administration and I have been working to conserve our natural resources and tackle the climate crisis head-on, but there’s always more we can do.”
While Evers touts the work his administration has done to protect the state’s environment, the main tool the state has used to conserve public land for the last four decades — the Knowles-Nelson Stewardship Grant program — is set to expire this summer due to Republican opposition to land conservation and the Legislature’s inability to reach a deal to reauthorize the program before adjourning for the year.
Howard Lerner, president of the Environmental Law and Policy Center, said at an online news conference Tuesday that there are still wins happening for the climate.
“We are getting things done in the Midwest, even while the Trump administration maintains its assault on core environmental values and rolls back years and years of federal progress,” he said.
He noted that a variety of groups across the Midwest worked together to protect the funding in the federal Great Lakes Restoration Initiative. He added, however, that more work will have to be done to protect Great Lakes shoreline communities from the effects of an increasingly fluctuating water level.
“When all is said and done, the impacts of climate change are leading to much greater fluctuations in Great Lakes water levels, and they’re leading to more intensive storms, high winds, heavy waves that batter the shoreline,” he said. “That puts a heavy impact and burden on our shoreline communities and on the shoreline infrastructure, and that’s infrastructure that we’ve got to protect and find ways of doing that.”
But the Great Lakes are also struggling with water quality, he said, largely in the form of contamination from factory farms that can lead to toxic events such as algae blooms. He said that in the wake of the federal government stepping back from its role protecting wetlands and waterways from runoff, Midwest states need to do more.
“We need to get policies in the states that reduce the amount of phosphorus, nitrates that flow into the water supply,” he said. “I think you’re going to see that [concentrated animal feeding operations] are going to be a bigger story going forward. Communities don’t want them, and E. coli and local water supplies and more toxic algae blooms in the Great Lakes is something that the public, I just don’t think is willing to tolerate.”

The darkened sky in the early afternoon, the tornado sirens wailing as baseball-sized hail shattered windows and dented car roofs, sounding like a series of explosions as drivers hurried home at 4 p.m. last week — all of it felt like the eerie first scene in an apocalyptic movie.
This is not a drill, I thought, watching the clouds tumbling and boiling overhead as my car radio and my phone began shrieking in unison and a robotic voice informed me that I should take shelter immediately from a tornado that was moving at 20 miles per hour directly toward my neighborhood.
We’ve all grown accustomed to the low background hum of climate anxiety. Suddenly it’s as loud and immediate as the crack of a giant hailstone on the windshield.
The changes to the planet we’ve been warned about for decades are suddenly hitting too close to home to ignore. Over the last year in Wisconsin we’ve endured smoke-filled skies from summer forest fires, massive floods, wild temperature swings and scarier, more serious storms.
This should be a wakeup call. But instead of accelerating efforts to head off climate catastrophe, our federal government is canceling renewable energy contracts and pushing for more coal plants, more oil drilling, more toxic mining on public lands, undoing protections for clean air and water, and accelerating the destruction of our shared environment in order to extract resources and build more wealth for a handful of people in the short term.
The price of this heedlessness is so enormous it hurts just to think about it.
Two days after the hail storm and tornado warnings sent me and my neighbors scrambling for cover, the U.S. Senate passed a bill to allow sulfide mining in the Superior National Forest, on the edge of the Boundary Waters Canoe Area Wilderness — an inexpressibly beautiful place that is precious to my family, the scene of some of the most formative experiences of our girls’ childhood, and the most visited wilderness area in the U.S. The Forest Service spent years studying how acid mine drainage — the toxic byproduct of sulfide-ore mining — could contaminate the interconnected lakes and streams that make up the Boundary Waters. Once that contamination starts, there is no way to reverse it, which is why an overwhelming majority of Minnesotans weighed in against the mine, and the federal government blocked it. Until that protection was overturned last week.
Minnesota Sen. Tina Smith took a heroic stand on the Senate floor last Wednesday, arguing late into the night, trying to persuade her colleagues not just to hold off on destroying this pristine place, but to forgo using an obscure maneuver that, in a 50-49 vote, redefined land management and knocked down longstanding protections for every piece of national forest in the country.
My colleague J. Patrick Coolican, editor of the Minnesota Reformer, described Smith pleading to an empty chamber, “I dearly hope the members of this body will think about their legacy in protecting the great places in this country.”
No future president can reinstate the mining ban that protected the Boundary Waters now that Congress used the obscure Congressional Review Act to strike it down. And it’s bigger than that. With their vote to open up mining near the Boundary Waters, “lawmakers have called into question the validity of every management plan issued by the U.S. Forest Service over the past several decades,” Alex Brown of Stateline reports. “That could result in legal chaos for thousands of permits covering logging, grazing, mining and outdoor recreation.” As Smith warned her Republican colleagues who want to protect the public lands they cherish in their home states, their vote means it’s now open season on those lands, too.
I couldn’t bear to talk with my daughters, who have spent every summer they can remember in the Boundary Waters, about the vote last week.
But this week, Earth Week, it’s time to confront it. All is not lost. Just as they stood up to the masked federal agents who descended on Minneapolis to tear immigrant families apart, Minnesotans are organizing to fight Twin Metals, a wholly owned subsidiary of the Chilean mining company Antofagasta, as it seeks state permits to open up its toxic mine. While mining proponents tout the mine as a job creator (ignoring the economic costs of destroying the nation’s most-visited wilderness), the Senate’s action mostly benefits a foreign mining company, which has a history of flouting environmental regulations and creating toxic spills in other countries, and which will likely sell the copper it extracts from Minnesota to China.
The least we Wisconsinites can do is to help our neighbors as they try to repel this deadly invasion and seizure of a priceless natural resource.
Friends of the Boundary Waters, based in Minnesota, is filing a lawsuit arguing that the congressional maneuver that opened up the mine is illegal. The group and its allies are also urging the Minnesota DNR to cancel Twin Metals’ leases for the mine, and pushing the Minnesota state legislature to ban mining in this sensitive area.
As Wisconsin Sen. Gaylor Nelson, the founder of Earth Day put it in his 1970 speech kicking off the modern environmental movement, protecting the environment is “not just an issue of survival, but an issue of how we survive.”
“Our goal is not just an environment of clean air and water and scenic beauty,” he said. “….Our goal is an environment of decency, quality and mutual respect for all human beings and all other living creatures. An environment without ugliness, without ghettos, without poverty, without discrimination, without hunger and without war.”
We need to protect that vision of life from the forces of greed and destruction that are engulfing us. We can’t let them write the end of the story.

Climate researchers predict storms that produce golf ball-size or larger hail will become more frequent, thanks to climate change.
According to a 2024 study by Northern Illinois University, a warmer climate increases water vapor in the air, which provides energy for thunderstorms like those seen April 14, 2026, in Wisconsin that produced large hail.
Hail is created when strong updrafts of air are pushed up into the colder atmosphere, freezing water droplets and pushing them around, making the droplets bigger and bigger. Eventually, those hailstones get too heavy and fall to earth.
“Our study suggests golf ball-size hail or larger will become more common because of more atmospheric instability, which leads to stronger thunderstorm updrafts,” NIU Atmospheric Science Professor Victor Gensini said.
A 2017 study in Nature that looked at historic patterns and forecasts also found hailstone size is expected to increase due to climate change.
This fact brief is responsive to conversations such as this one.

Jessika Trancik, a professor in MIT’s Institute for Data, Systems, and Society, has been named the new director of the Sociotechnical Systems Research Center (SSRC), effective July 1. The SSRC convenes and supports researchers focused on problems and solutions at the intersection of technology and its societal impacts.
Trancik conducts research on technology innovation and energy systems. At the Trancik Lab, she and her team develop methods drawing on engineering knowledge, data science, and policy analysis. Their work examines the pace and drivers of technological change, helping identify where innovation is occurring most rapidly, how emerging technologies stack up against existing systems, and which performance thresholds matter most for real-world impact. Her models have been used to inform government innovation policy and have been applied across a wide range of industries.
“Professor Trancik’s deep expertise in the societal implications of technology, and her commitment to developing impactful solutions across industries, make her an excellent fit to lead SSRC,” says Maria C. Yang, interim dean of engineering and William E. Leonhard (1940) Professor of Mechanical Engineering.
Much of Trancik’s research focuses on the domain of energy systems, and establishing methods for energy technology evaluation, including of their costs, performance, and environmental impacts. She covers a wide range of energy services — including electricity, transportation, heating, and industrial processes. Her research has applications in solar and wind energy, energy storage, low-carbon fuels, electric vehicles, and nuclear fission. Trancik is also known for her research on extreme events in renewable energy availability.
A prolific researcher, Trancik has helped measure progress and inform the development of solar photovoltaics, batteries, electric vehicle charging infrastructure, and other low-carbon technologies — and anticipate future trends. One of her widely cited contributions includes quantifying learning rates and identifying where targeted investments can most effectively accelerate innovation. These tools have been used by U.S. federal agencies, international organizations, and the private sector to shape energy R&D portfolios, climate policy, and infrastructure planning.
Trancik is committed to engaging and informing the public on energy consumption. She and her team developed the app carboncounter.com, which helps users choose cars with low costs and low environmental impacts.
As an educator, Trancik teaches courses for students across MIT’s five schools and the MIT Schwarzman College of Computing.
“The question guiding my teaching and research is how do we solve big societal challenges with technology, and how can we be more deliberate in developing and supporting technologies to get us there?” Trancik said in an article about course IDS.521/IDS.065 (Energy Systems for Climate Change Mitigation).
Trancik received her undergraduate degree in materials science and engineering from Cornell University. As a Rhodes Scholar, she completed her PhD in materials science at the University of Oxford. She subsequently worked for the United Nations in Geneva, Switzerland, and the Earth Institute at Columbia University. After serving as an Omidyar Research Fellow at the Santa Fe Institute, she joined MIT in 2010 as a faculty member.
Trancik succeeds Fotini Christia, the Ford International Professor of Social Sciences in the Department of Political Science and director of IDSS, who previously served as director of SSRC.

As a major contributor to global carbon dioxide (CO2) emissions, the transportation sector has immense potential to advance decarbonization. However, a zero-emissions global supply chain requires re-imagining reliance on a heavy-duty trucking industry that emits 810,000 tons of CO2, or 6 percent of the United States’ greenhouse gas emissions, and consumes 29 billion gallons of diesel annually in the U.S. alone.
A new study by MIT researchers, presented at the recent American Society of Mechanical Engineers 2024 International Design Engineering Technical Conferences and Computers and Information in Engineering Conference, quantifies the impact of a zero-emission truck’s design range on its energy storage requirements and operational revenue. The multivariable model outlined in the paper allows fleet owners and operators to better understand the design choices that impact the economic feasibility of battery-electric and hydrogen fuel cell heavy-duty trucks for commercial application, equipping stakeholders to make informed fleet transition decisions.
“The whole issue [of decarbonizing trucking] is like a very big, messy pie. One of the things we can do, from an academic standpoint, is quantify some of those pieces of pie with modeling, based on information and experience we’ve learned from industry stakeholders,” says ZhiYi Liang, PhD student on the renewable hydrogen team at the MIT K. Lisa Yang Global Engineering and Research Center (GEAR) and lead author of the study. Co-authored by Bryony DuPont, visiting scholar at GEAR, and Amos Winter, the Germeshausen Professor in the MIT Department of Mechanical Engineering, the paper elucidates operational and socioeconomic factors that need to be considered in efforts to decarbonize heavy-duty vehicles (HDVs).
Operational and infrastructure challenges
The team’s model shows that a technical challenge lies in the amount of energy that needs to be stored on the truck to meet the range and towing performance needs of commercial trucking applications. Due to the high energy density and low cost of diesel, existing diesel drivetrains remain more competitive than alternative lithium battery-electric vehicle (Li-BEV) and hydrogen fuel-cell-electric vehicle (H2 FCEV) drivetrains. Although Li-BEV drivetrains have the highest energy efficiency of all three, they are limited to short-to-medium range routes (under 500 miles) with low freight capacity, due to the weight and volume of the onboard energy storage needed. In addition, the authors note that existing electric grid infrastructure will need significant upgrades to support large-scale deployment of Li-BEV HDVs.
While the hydrogen-powered drivetrain has a significant weight advantage that enables higher cargo capacity and routes over 750 miles, the current state of hydrogen fuel networks limits economic viability, especially once operational cost and projected revenue are taken into account. Deployment will most likely require government intervention in the form of incentives and subsidies to reduce the price of hydrogen by more than half, as well as continued investment by corporations to ensure a stable supply. Also, as H2-FCEVs are still a relatively new technology, the ongoing design of conformal onboard hydrogen storage systems — one of which is the subject of Liang’s PhD — is crucial to successful adoption into the HDV market.
The current efficiency of diesel systems is a result of technological developments and manufacturing processes established over many decades, a precedent that suggests similar strides can be made with alternative drivetrains. However, interactions with fleet owners, automotive manufacturers, and refueling network providers reveal another major hurdle in the way that each “slice of the pie” is interrelated — issues must be addressed simultaneously because of how they affect each other, from renewable fuel infrastructure to technological readiness and capital cost of new fleets, among other considerations. And first steps into an uncertain future, where no one sector is fully in control of potential outcomes, is inherently risky.
“Besides infrastructure limitations, we only have prototypes [of alternative HDVs] for fleet operator use, so the cost of procuring them is high, which means there isn’t demand for automakers to build manufacturing lines up to a scale that would make them economical to produce,” says Liang, describing just one step of a vicious cycle that is difficult to disrupt, especially for industry stakeholders trying to be competitive in a free market.
Quantifying a path to feasibility
“Folks in the industry know that some kind of energy transition needs to happen, but they may not necessarily know for certain what the most viable path forward is,” says Liang. Although there is no singular avenue to zero emissions, the new model provides a way to further quantify and assess at least one slice of pie to aid decision-making.
Other MIT-led efforts aimed at helping industry stakeholders navigate decarbonization include an interactive mapping tool developed by Danika MacDonell, Impact Fellow at the MIT Climate and Sustainability Consortium (MCSC); alongside Florian Allroggen, executive director of MITs Zero Impact Aviation Alliance; and undergraduate researchers Micah Borrero, Helena De Figueiredo Valente, and Brooke Bao. The MCSC’s Geospatial Decision Support Tool supports strategic decision-making for fleet operators by allowing them to visualize regional freight flow densities, costs, emissions, planned and available infrastructure, and relevant regulations and incentives by region.
While current limitations reveal the need for joint problem-solving across sectors, the authors believe that stakeholders are motivated and ready to tackle climate problems together. Once-competing businesses already appear to be embracing a culture shift toward collaboration, with the recent agreement between General Motors and Hyundai to explore “future collaboration across key strategic areas,” including clean energy.
Liang believes that transitioning the transportation sector to zero emissions is just one part of an “energy revolution” that will require all sectors to work together, because “everything is connected. In order for the whole thing to make sense, we need to consider ourselves part of that pie, and the entire system needs to change,” says Liang. “You can’t make a revolution succeed by yourself.”
