There is growing attention on the links between artificial intelligence and increased energy demands. But while the power-hungry data centers being built to support AI could potentially stress electricity grids, increase customer prices and service interruptions, and generally slow the transition to clean energy, the use of artificial intelligence can also help the energy transition.

For example, use of AI is reducing energy consumption and associated emissions in buildings, transportation, and industrial processes. In addition, AI is helping to optimize the design and siting of new wind and solar installations and energy storage facilities.

On electric power grids, using AI algorithms to control operations is helping to increase efficiency and reduce costs, integrate the growing share of renewables, and even predict when key equipment needs servicing to prevent failure and possible blackouts. AI can help grid planners schedule investments in generation, energy storage, and other infrastructure that will be needed in the future. AI is also helping researchers discover or design novel materials for nuclear reactors, batteries, and electrolyzers.

Researchers at MIT and elsewhere are actively investigating aspects of those and other opportunities for AI to support the clean energy transition. At its 2025 research conference, MITEI announced the Data Center Power Forum, a targeted research effort for MITEI member companies interested in addressing the challenges of data center power demand.

Controlling real-time operations

Customers generally rely on receiving a continuous supply of electricity, and grid operators get help from AI to make that happen — while optimizing the storage and distribution of energy from renewable sources at the same time.

But with more installation of solar and wind farms — both of which provide power in smaller amounts, and intermittently — and the growing threat of weather events and cyberattacks, ensuring reliability is getting more complicated. “That’s exactly where AI can come into the picture,” explains Anuradha Annaswamy, a senior research scientist in MIT’s Department of Mechanical Engineering and director of MIT’s Active-Adaptive Control Laboratory. “Essentially, you need to introduce a whole information infrastructure to supplement and complement the physical infrastructure.”

The electricity grid is a complex system that requires meticulous control on time scales ranging from decades all the way down to microseconds. The challenge can be traced to the basic laws of power physics: electricity supply must equal electricity demand at every instant, or generation can be interrupted. In past decades, grid operators generally assumed that generation was fixed — they could count on how much electricity each large power plant would produce — while demand varied over time in a fairly predictable way. As a result, operators could commission specific power plants to run as needed to meet demand the next day. If some outages occurred, specially designated units would start up as needed to make up the shortfall.

Today and in the future, that matching of supply and demand must still happen, even as the number of small, intermittent sources of generation grows and weather disturbances and other threats to the grid increase. AI algorithms provide a means of achieving the complex management of information needed to forecast within just a few hours which plants should run while also ensuring that the frequency, voltage, and other characteristics of the incoming power are as required for the grid to operate properly.

Moreover, AI can make possible new ways of increasing supply or decreasing demand at times when supplies on the grid run short. As Annaswamy points out, the battery in your electric vehicle (EV), as well as the one charged up by solar panels or wind turbines, can — when needed — serve as a source of extra power to be fed into the grid. And given real-time price signals, EV owners can choose to shift charging from a time when demand is peaking and prices are high to a time when demand and therefore prices are both lower. In addition, new smart thermostats can be set to allow the indoor temperature to drop or rise —  a range defined by the customer — when demand on the grid is peaking. And data centers themselves can be a source of demand flexibility: selected AI calculations could be delayed as needed to smooth out peaks in demand. Thus, AI can provide many opportunities to fine-tune both supply and demand as needed.

In addition, AI makes possible “predictive maintenance.” Any downtime is costly for the company and threatens shortages for the customers served. AI algorithms can collect key performance data during normal operation and, when readings veer off from that normal, the system can alert operators that something might be going wrong, giving them a chance to intervene. That capability prevents equipment failures, reduces the need for routine inspections, increases worker productivity, and extends the lifetime of key equipment.

Annaswamy stresses that “figuring out how to architect this new power grid with these AI components will require many different experts to come together.” She notes that electrical engineers, computer scientists, and energy economists “will have to rub shoulders with enlightened regulators and policymakers to make sure that this is not just an academic exercise, but will actually get implemented. All the different stakeholders have to learn from each other. And you need guarantees that nothing is going to fail. You can’t have blackouts.”

Using AI to help plan investments in infrastructure for the future

Grid companies constantly need to plan for expanding generation, transmission, storage, and more, and getting all the necessary infrastructure built and operating may take many years, in some cases more than a decade. So, they need to predict what infrastructure they’ll need to ensure reliability in the future. “It’s complicated because you have to forecast over a decade ahead of time what to build and where to build it,” says Deepjyoti Deka, a research scientist in MITEI.

One challenge with anticipating what will be needed is predicting how the future system will operate. “That’s becoming increasingly difficult,” says Deka, because more renewables are coming online and displacing traditional generators. In the past, operators could rely on “spinning reserves,” that is, generating capacity that’s not currently in use but could come online in a matter of minutes to meet any shortfall on the system. The presence of so many intermittent generators — wind and solar — means there’s now less stability and inertia built into the grid. Adding to the complication is that those intermittent generators can be built by various vendors, and grid planners may not have access to the physics-based equations that govern the operation of each piece of equipment at sufficiently fine time scales. “So, you probably don’t know exactly how it’s going to run,” says Deka.

And then there’s the weather. Determining the reliability of a proposed future energy system requires knowing what it’ll be up against in terms of weather. The future grid has to be reliable not only in everyday weather, but also during low-probability but high-risk events such as hurricanes, floods, and wildfires, all of which are becoming more and more frequent, notes Deka. AI can help by predicting such events and even tracking changes in weather patterns due to climate change.

Deka points out another, less-obvious benefit of the speed of AI analysis. Any infrastructure development plan must be reviewed and approved, often by several regulatory and other bodies. Traditionally, an applicant would develop a plan, analyze its impacts, and submit the plan to one set of reviewers. After making any requested changes and repeating the analysis, the applicant would resubmit a revised version to the reviewers to see if the new version was acceptable. AI tools can speed up the required analysis so the process moves along more quickly. Planners can even reduce the number of times a proposal is rejected by using large language models to search regulatory publications and summarize what’s important for a proposed infrastructure installation.

Harnessing AI to discover and exploit advanced materials needed for the energy transition

“Use of AI for materials development is booming right now,” says Ju Li, MIT’s Carl Richard Soderberg Professor of Power Engineering. He notes two main directions.

First, AI makes possible faster physics-based simulations at the atomic scale. The result is a better atomic-level understanding of how composition, processing, structure, and chemical reactivity relate to the performance of materials. That understanding provides design rules to help guide the development and discovery of novel materials for energy generation, storage, and conversion needed for a sustainable future energy system.

And second, AI can help guide experiments in real time as they take place in the lab. Li explains: “AI assists us in choosing the best experiment to do based on our previous experiments and — based on literature searches — makes hypotheses and suggests new experiments.”

He describes what happens in his own lab. Human scientists interact with a large language model, which then makes suggestions about what specific experiments to do next. The human researcher accepts or modifies the suggestion, and a robotic arm responds by setting up and performing the next step in the experimental sequence, synthesizing the material, testing the performance, and taking images of samples when appropriate. Based on a mix of literature knowledge, human intuition, and previous experimental results, AI thus coordinates active learning that balances the goals of reducing uncertainty with improving performance. And, as Li points out, “AI has read many more books and papers than any human can, and is thus naturally more interdisciplinary.”

The outcome, says Li, is both better design of experiments and speeding up the “work flow.” Traditionally, the process of developing new materials has required synthesizing the precursors, making the material, testing its performance and characterizing the structure, making adjustments, and repeating the same series of steps. AI guidance speeds up that process, “helping us to design critical, cheap experiments that can give us the maximum amount of information feedback,” says Li.

“Having this capability certainly will accelerate material discovery, and this may be the thing that can really help us in the clean energy transition,” he concludes. “AI [has the potential to] lubricate the material-discovery and optimization process, perhaps shortening it from decades, as in the past, to just a few years.” 

MITEI’s contributions

At MIT, researchers are working on various aspects of the opportunities described above. In projects supported by MITEI, teams are using AI to better model and predict disruptions in plasma flows inside fusion reactors — a necessity in achieving practical fusion power generation. Other MITEI-supported teams are using AI-powered tools to interpret regulations, climate data, and infrastructure maps in order to achieve faster, more adaptive electric grid planning. AI-guided development of advanced materials continues, with one MITEI project using AI to optimize solar cells and thermoelectric materials.

Other MITEI researchers are developing robots that can learn maintenance tasks based on human feedback, including physical intervention and verbal instructions. The goal is to reduce costs, improve safety, and accelerate the deployment of the renewable energy infrastructure. And MITEI-funded work continues on ways to reduce the energy demand of data centers, from designing more efficient computer chips and computing algorithms to rethinking the architectural design of the buildings, for example, to increase airflow so as to reduce the need for air conditioning.

In addition to providing leadership and funding for many research projects, MITEI acts as a convenor, bringing together interested parties to consider common problems and potential solutions. In May 2025, MITEI’s annual spring symposium — titled “AI and energy: Peril and promise” — brought together AI and energy experts from across academia, industry, government, and nonprofit organizations to explore AI as both a problem and a potential solution for the clean energy transition. At the close of the symposium, William H. Green, director of MITEI and Hoyt C. Hottel Professor in the MIT Department of Chemical Engineering, noted, “The challenge of meeting data center energy demand and of unlocking the potential benefits of AI to the energy transition is now a research priority for MITEI.”

Around 80 percent of global energy production today comes from the combustion of fossil fuels. Combustion, or the process of converting stored chemical energy into thermal energy through burning, is vital for a variety of common activities including electricity generation, transportation, and domestic uses like heating and cooking — but it also yields a host of environmental consequences, contributing to air pollution and greenhouse gas emissions.

Sili Deng, the Doherty Chair in Ocean Utilization and associate professor of mechanical engineering at MIT, is leading research to drive the transition from the heavy dependence on fossil fuels to renewable energy with storage.

“I was first introduced to flame synthesis in my junior year in college,” Deng says. “I realized you can actually burn things to make things, [and] that was really fascinating.”

Deng says she ultimately picked combustion as a focus of her work because she likes the intellectual challenge the concept offers. “In combustion you have chemistry, and you have fluid mechanics. Each subject is very rich in science. This also has very strong engineering implications and applications.”

Deng’s research group targets three areas: building up fundamental knowledge on combustion processes and emissions; developing alternative fuels and metal combustion to replace fossil fuels; and synthesizing flame-based materials for catalysis and energy storage, which can bring down the cost of manufacturing battery materials.

One focus of the team has been on low-cost, low-emission manufacturing of cathode materials for lithium-ion batteries. Lithium-ion batteries play an increasingly critical role in transportation electrification (e.g., batteries for electric vehicles) and grid energy storage for electricity that is generated from renewable energy sources like wind and solar. Deng’s team has developed a technology they call flame-assisted spray pyrolysis, or FASP, which can help reduce the high manufacturing costs associated with cathode materials.

FASP is based on flame synthesis, a technology that dates back nearly 3,000 years. In ancient China, this was the primary way black ink materials were made. “[People burned] vegetables or woods, such that afterwards they can collect the solidified smoke,” Deng explains. “For our battery applications, we can try to fit in the same formula, but of course with new tweaks.”

The team is also interested in developing alternative fuels, including looking at the use of metals like aluminum to power rockets. “We’re interested in utilizing aluminum as a fuel for civil applications,” Deng says, because aluminum is abundant in the earth, cheap, and it’s available globally. “What we are trying to do is to understand [aluminum combustion] and be able to tailor its ignition and propagation properties.”

Among other accolades, Deng is a 2025 recipient of the Hiroshi Tsuji Early Career Researcher Award from the Combustion Institute, an award that recognizes excellence in fundamental or applied combustion science research.

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.

The Carbon Storage Problem We’ve got all these great solutions capturing carbon, typically from air or industrial emitters. But capture is only half...

The post Speeding Up Earth’s Natural CO2 Mineralization Cycle Can Recover All of the CO2 from Fossil Fuels appeared first on Cleantech Group.

A planned 325-megawatt battery energy storage system at a key location on New England’s power grid could boost Connecticut’s access to carbon-free power — but only if it can overcome complicated legal and political barriers. 

An Israeli firm, Sunflower Sustainable Investments, filed an application in October for the project with the Connecticut Siting Council, which has regulatory authority over the siting of power facilities.

The $200 million project, called Windham Energy Center, would be located on a largely undeveloped 63-acre site in Killingly, Connecticut, that was slated for construction of a fossil fuel power plant a few years ago. There is existing electric transmission infrastructure immediately adjacent to the site, and the project will connect to the grid via a 345-kilovolt transmission line. 

A spokesman for Windham Energy, Jonathan Milley, said the location is ideal for a battery facility. 

“If you look at the topology of the New England grid, this is at the intersection of the Millstone nuclear power plant and Brayton Point,” in Somerset, Massachusetts, where approved offshore wind projects will eventually be connected to the grid, Milley said. “This nodal location will at certain times of the day and under certain conditions have some of the lowest cost energy available to it on the grid.” 

The project would consist of lithium-ion batteries installed in racks in prefabricated containers, and a switching station operated by Eversource to connect them to the transmission line. The equipment would be located within 20 acres of the total project site. 

But the project is currently hung up by an administrative roadblock. That’s because in 2019, the siting council approved an application from NTE Energy to build a 650-megawatt natural gas plant on a portion of the same property. 

That project, which ran into a storm of opposition from environmental advocates, was never built, and NTE Energy has since dissolved. But nevertheless, on Nov. 8, the siting council’s executive director, Melanie Bachman, notified Windham Energy that it is “premature” for the body to review their application because the Certificate of Environmental Compatibility and Public Need previously issued to NTE still exists. 

The certificate has not been surrendered to the council, she said. And it will otherwise only be void if construction on the gas plant has not been completed by September 28, 2026. 

Windham Energy has asked the council to declare the certificate no longer valid, noting that NTE Energy no longer exists nor holds an option to purchase the property, and that its energy supply agreement with regional grid operator ISO-New England was also revoked in 2022. 

Milley said battery storage is needed to complement the state’s offshore wind goals; the batteries can store surplus energy from wind sources when production is high, and then dispatch it to the grid when it is needed. In 2021, state lawmakers set a goal of at least 1,000 megawatts of energy storage deployment by December 31, 2030.

“If there’s a developer willing to build what the state is looking for and not asking for anything else, it doesn’t seem like asking too much for the council to nullify an existing certificate for an entity that doesn’t exist,” Milley said. 

For now, counsel for Windham Energy has sent a letter by certified mail to Stephanie Clarkson, who they say is the last known contact for NTE Energy, asking her to “advise whether the Certificate issued to NTE should be an impediment” to their proposed project.

Addressing safety concerns

The town of Killingly has requested party status in the hearings before the siting council. 

In a letter to Windham Energy following a meeting with the developers, Town Council chair Jason Alexander and vice chair Tammy Wakefield raised concerns about the potential for fire at the facility, pointing to a recent fire at a battery storage facility in New York, and asked how they would prevent a similar event.  

Three battery storage projects caught fire in New York in 2023, prompting Gov. Kathy Hochul to convene a working group to draft updates to the state’s fire code to improve safety and emergency preparedness in the planning of such projects. 

Other towns in Connecticut have also raised concerns about fires for much smaller battery storage projects proposed by Key Capture Energy, of Albany, New York.

Milley says town officials are “right to ask these questions,” and he is focused on addressing their concerns. He noted that Windham plans to use lithium iron phosphate batteries, a type of lithium battery he says is much less prone to fire.

“The element in the battery is iron, which doesn’t burn,” he said. 

However, he added, Windham fully intends to work with town and state fire authorities to develop a response plan “whether it’s a strict requirement or not.” 

In the meantime, Windham Energy has filed a motion with the siting council to reopen the docket concerning NTE Energy so that it might modify its decision and revoke the earlier issued certificate. 

The council is expected to take up that motion during its Feb. 6 meeting.

A solar-powered microgrid project backed with funding from the Biden administration aims to reduce energy burdens and provide backup power to a tiny northern Minnesota tribal community.

The Pine Point Resilience Hub would serve an elementary school and community center in Pine Point, an Anishinaabe village of about 330 people on the White Earth Reservation.

In June, the project was selected to receive $1.75 million from the U.S. Department of Energy’s Energy Storage for Social Equity (ES4SE) Program, which helps underserved and frontline communities leverage energy storage to make electricity more affordable and reliable. It’s part of a slew of Biden administration funding related to grid resilience and energy equity that has spurred several tribal microgrid projects across the country.

The developers, locally owned 8th Fire Solar and San Francisco-based 10Power, hope to finish the project next year, and have also secured funding from Minnesota’s Solar for Schools program and foundation grants but said they still need to raise about $1 million. They’re also counting on receiving about $1.5 million in federal tax credits, which face an uncertain future with the incoming Trump administration. 

“The idea of the microgrid is to help with infrastructure,” said Gwe Gasco, a member of the White Earth Nation and the program coordinator with 8th Fire Solar, a thermal solar company based on the reservation.

Tribal communities were largely bypassed during the massive, federally funded push under the Rural Electrification Act of 1936 to bring electricity to remote rural areas of the country. As a result, grid infrastructure on many reservations remains insufficient to this day, with an estimated 1 in 7 Native American households on reservations lacking electricity connections, and many more contending with unreliable service.

On top of higher-than-average electric reliability issues, tribal communities also generally pay higher rates for electricity and face higher energy burdens due to poverty and substandard housing.

On the White Earth Reservation, these challenges are most pronounced in Pine Point, where one-third of residents live in poverty. Gasco said the area is among the first to suffer from outages, with eleven occurring over the last five years, according to the Itasca-Mantrap Electric Cooperative that serves the area.

The Pine Point Resilience Hub project will build on an existing 21-kilowatt solar array, adding another 500 kilowatts of solar capacity along with a 2.76 megawatt-hour battery storage system, enough to provide about 12 hours worth of backup power for residents to be able to charge cell phones, power medical equipment, or stay warm in the event of a power outage.

Gasco said the microgrid could be especially important in the winter, given the area’s “brutally cold” weather and reliance on electric heat. They also hope it will reduce utility costs, though they are still negotiating with the local electric co-op on rates for power the system sends and receives from the utility’s grid. Itasca-Mantrap President and CEO Christine Fox said it doesn’t set net metering rates, which are determined by its electricity supplier.

The project developers hope to qualify for additional federal tax credits by using equipment largely produced in the U.S., including Minnesota-built Heliene solar panels, inverters made in Massachusetts, and Ohio-produced solar racks.

The developers have partnered with the Pine Point School District, which plans to incorporate the microgrid into an Ojibwe-language curriculum on renewable energy. A monitoring interface will allow students to see real-time data in the classroom.

“It’s powerful to me that this (project) is at a school where we’re hoping to inspire the next generation of kids,” said Sandra Kwak, CEO and founder of 10Power, a for-profit company that specializes in developing renewable energy projects in tribal communities.

Corey Orehek, senior business developer for Ziegler Energy Solutions, which has been hired to do the installation, said they plan to work with a local community college to train students for solar jobs. 

“One of the things that we want to drive in this is workforce development,” Orehek said. “We want to leave something that’s not only a project that’ll last 30 years but provide the training and experience for community members to either start their own energy companies or become contractors in the clean energy workforce.”

The resilience hub is the second such project announced by a Minnesota tribe in just recent months. The Red Lake Nation received $3.15 million from the U.S. Department of Energy’s Local Government Energy Program in late September for a behind-the-meter microgrid project at a secondary school.

The Shakopee Mdewakanton Sioux Community is also working with Minnesota Valley Electric Cooperative to build a $9 million microgrid with U.S. Department of Energy funding. The electric cooperative will install a 4 megawatt-hour energy storage system and add a 1 megawatt solar system at the reservation in suburban Minneapolis.

It’s unclear whether federal funding for such projects will continue in President-elect Trump’s second term, but for now tribal energy advocates see microgrids as a good solution to both lower energy burdens and improve reliability.   

“This is a great opportunity to create a success story in terms of leveraging cutting-edge technology, being able to help frontline communities, and for tribes and co-ops to work together,” Kwak said.

Seventeen days after Hurricane Helene devastated Western North Carolina, tearing down power lines, destroying water mains, and disabling cell phone towers, the signs of relief were hard to miss. 

Trucks formed a caravan along Interstate 40, filled with camouflaged soldiers, large square tanks of water, and essentials from pet food to diapers. In towns, roadside signs — official versions emblazoned with nonprofit relief logos and wooden makeshift ones scrawled with paint — advertised free food and water. 

And then there were the generators. 

The noisy machines powered the trailers where Asheville residents sought showers, weeks after the city’s water system failed. They fueled the food trucks delivering hot meals to the thousands without working stoves. They filtered water for communities to drink and flush toilets. 

Western North Carolina is far from unique. In the wake of disaster, generators are a staple of relief efforts around the globe. But across the region, a New Orleans-based nonprofit is working to displace as many of these fossil fuel burners as they can, swapping in batteries charged with solar panels instead. 

It’s the largest response effort the Footprint Project has ever deployed in its short life, and organizers hope the impact will extend far into the future. 

“If we can get this sustainable tech in fast, then when the real rebuild happens, there’s a whole new conversation that wouldn’t have happened if we were just doing the same thing that we did every time,” said Will Heegaard, operations director for the organization.  

“Responders use what they know works, and our job is to get them stuff that works better than single-use fossil fuels do,” he said. “And then, they can start asking for that. It trickles up to a systems change.” 

A ‘no-brainer’ solution to the problem of gas generators 

The rationale for diesel and gas generators is simple: they’re widely available. They’re relatively easy to operate. Assuming fuel is available, they can run 24-7, keeping people warm, fed, and connected to their loved ones even when the electric grid is down. Indubitably, they save lives.  

But they’re not without downsides. The burning of fossil fuels causes not just more just more carbon that exacerbates the climate crisis, but smog and soot-forming air pollutants that can trigger asthma attacks and other respiratory problems.  

In Puerto Rico after Hurricane Maria, generators were so prevalent after the electric grid failed that harmful air pollution in San Juan soared above the safe legal limit. The risk is especially acute for sensitive populations who turn to generators for powering vital equipment like oxygenators. 

There are also practical challenges. Generators aren’t cheap, retailing at big box stores for more than $1,000. Once initial fuel supplies run out — as happened in parts of Western North Carolina in the immediate aftermath of Helene — it can be difficult and costly to find more. And the machines are noisy, potentially harming health and creating more stress for aid workers and the people they serve. 

Heegaard witnessed these challenges firsthand in Guinea in 2016 when he was responding to an Ebola outbreak. A paramedic, his job was to train locals to collect blood samples and store them in generator-powered refrigerators that would be motorcycled to the city of Conakry for testing. He had a grant to give cash reimbursements to the lab techs for the fuel. 

“This is so hard already, and the idea of doing a cash reimbursement in a super poor rural country for gas generators seems really hard,” Heegaard recalled thinking. “I had heard of solar refrigerators. I asked the local logistician in Conakry, ‘Are these things even possible?’”  

The next day, the logistician said they were. They could be installed within a month. “It was just a no-brainer,” said Heegaard. “The only reason we hadn’t done it is the grant wasn’t written that way.” 

‘Game changing for a response’

Two years later, the Footprint Project was born of that experience. With just seven full-time staff, the group cycles in workers in the wake of disaster, partnering up with local solar companies, nonprofits and others, to gather supplies and distribute as many as they can. 

They deploy solar-powered charging stations, water filtration systems, and other so-called climate tech to communities who need it most — starting with those without power, water, or a generator at all, and extending to those looking to offset their fossil fuel combustion.

The group has now built nearly 50 such solar-powered microgrids in the region, from Lake Junaluska to Linville Falls, more than it has ever supplied in the wake of disaster. The recipients range from volunteer fire stations to trailer parks to an art collective in West Asheville.

Mike Talyad, a photographer who last year launched the collective to support artists of color, teamed up with the Grassroots Aid Partnership, a national nonprofit, to fill in relief gaps in the wake of Helene. “The whole city was trying to figure it out,” he said. 

Solar panels from Footprint that initially powered a water filter have now largely displaced the generators for the team’s food trucks, which last week were providing 1,000 meals a day. “When we did the switchover,” Talyad said, “it was a time when gas was still questionable.”

Last week, the team at Footprint also provided six solar panels, a Tesla battery, and charging station to displace a noisy generator at a retirement community in South Asheville.

The device was powering a system that sucked water from a pond, filtered it, and rendered it potable. Picking up their jugs of drinking water, a steady flow of residents oohed and aahed as the solar panels were installed, and sighed in relief when the din of the generator abated. 

“Most responders are not playing with solar microgrids because they’re better for the environment,” said Heegaard. “They’re playing with it because if they can turn their generator off for 12 hours a day, that means literally half the fuel savings. Some of them are spending tens of thousands of dollars a month on diesel or gas. That is game changing for a response.” 

‘Showing up for their neighbors’

Footprint’s robust relief effort and the variety of its beneficiaries is owed in part to the scale of Helene’s destruction, with more than 1 million in North Carolina alone who initially lost power.  

“It’s really hard to put into words what’s happening out there right now,” said Matt Abele, the executive director of the North Carolina Sustainable Energy Association, who visited in the early days after the storm. “It is just the most heartbreaking thing I’ve ever seen — whole mobile home parks that are just completely gone.” 

But the breadth of the response is also owed to Footprint’s approach to aid, which is rooted in connections to grassroots groups, government organizations, and the local solar industry. All have partnered together for the relief effort. 

“We’ve been incredibly overwhelmed by the positive response that we’ve seen from the clean energy community,” Abele said, “both from an equipment donation standpoint and a financial resources standpoint.” 

Some four hours east of the devastation in Western North Carolina, Greentech Renewables Raleigh has been soliciting and storing solar panels and other goods. It’s also raising money for products that are harder to get for free — like PV wire and batteries. Then it trucks the supplies west.

“We’ve got bodies, we’ve got trucks, we’ve got relationships,” said Shasten Jolley, the manager at the company, which warehouses and sells supplies to a variety of installers. “So, we try to utilize all those things to help out.”

The cargo is delivered to Mars Hill, a tiny college town about 20 miles north of Asheville that was virtually untouched by Helene. Through a local regional government organization, Frank Johnson, the owner of a robotics company, volunteered his 110,000-square-foot facility for storage.

Johnson is just one example of how people in the region have leapt to help each other, said Abele, who’s based in Raleigh.

“You can tell when you’re out there,” he said, “that so many people in the community are coping by showing up for their neighbors.”

‘Available for the next response’

To be sure, Footprint’s operations aren’t seamless at every turn. For instance, most of the donated solar panels designated for the South Asheville retirement community didn’t work, a fact the installers learned once they’d made the 40-minute drive in the morning and tried to connect them to the system. They returned later that afternoon with functioning units, but then faced the challenge of what to do with the broken ones.

“This is solar aid waste,” Heegaard said. “The last site we did yesterday had the same problem. Now we have to figure out how to recycle them.”

It’s also not uncommon for the microgrids to stop working, Heegaard said, because of understandable operator errors, like running them all night to provide heat.  

But above all, the problem for Footprint is scale. A tiny organization among behemoth relief groups, they simply don’t have the bandwidth for a larger response. When Milton followed immediately on the heels of Helene, Heegaard’s group made the difficult choice to hunker down in North Carolina. 

With climate-fueled weather disasters poised to increase, the organization hopes to entice the biggest, most well-resourced players in disaster relief to start regularly using solar microgrids in their efforts. 

As power is slowly restored across the region, with just over 5,000 remaining without electricity, there’s also the question of what comes next.

While there’s a parallel conversation underway among advocates and policymakers about making microgrids and distributed solar a more permanent feature of the grid, Footprint also hopes to inspire some of that change from the ground up. Maybe the volunteer fire station decides to put solar panels on its roof when it rebuilds, for instance. 

“We can change the conversation around resilience and recovery by directly pointing to something that worked when the lights were out and debris was in the street,” Heegaard said.

As for the actual Footprint equipment, the dream is to create “lending libraries” in places like Asheville, to be cycled in and out of community events and disaster relief.

“The solar trailer or the microgrid or the water maker that went to the Burnsville elementary school right after the storm – that can be recycled and used to power the music stage or the movie in the park,” Heegaard said. “Then that equipment is here, it’s being utilized, and it’s available for the next response, whether it’s in Knoxville or Atlanta or South Carolina.”

Last year, Michigan got attention as the first Midwestern state to adopt an energy storage standard. Energy storage is essential for the clean energy transition because it allows clean electricity initially generated by sources like wind and solar to be available at all times.

The standard calls for 2,500 MW of energy storage to be deployed by 2030. This storage will be fulfilled by a range of technologies, with lithium-ion batteries, the type of the storage that has grown rapidly across the U.S. and the world in recent years, chief among them. But it’s not too early to start thinking about how this standard (and future standards) will also involve new technologies that serve different needs, including shifting low-cost energy over longer periods of time to support electric reliability and affordability. A U.S. Department of Energy report found that to achieve a net-zero economy, the U.S. grid may need 225 GW to 460 GW of long-duration energy storage by 2050. By comparison, the U.S. currently has over 500 GW of gas power plants, and battery storage capacity is expected to double to about 30 GW by the end of this year, according to the U.S. Energy Information Administration.

Fortunately, Michigan’s energy legislation anticipated this need. The legislation that created the 2030 storage target also ordered Michigan regulators to report to lawmakers on the potential for long-duration and multi-day energy storage. The Michigan Public Service Commission (MPSC) is in the midst of this study right now.

But how is “long-duration” energy storage different from the battery storage that is growing quickly in Michigan and across the country right now? It’s all about the concept of duration, which refers to how long a storage resource like a battery can discharge stored energy until it is out of capacity. Most of the batteries being built at utility scale right now have a duration of around four hours. But long-duration storage refers to resources that have a duration of over 8 hours and up to well over 100 hours.

This longer duration unlocks capabilities that will make 100% clean electricity a reality. Short-duration storage right now can cover shortfalls in wind and solar on an hour-by-hour basis. But what about if there is a shortfall in energy supply expected not for just a few hours, but from one day to the next? Or from one month to the next? Those situations arise especially in seasons like winter, where cloud cover can linger and hamper solar energy production for extended periods of time. That is where the need for long-duration storage comes in. Long-duration storage could become a capacity resource that grid operators can tap to reliably deal with long-term fluctuations in energy supply, like those caused by changes in the season from summer to winter.

What would this type of energy storage actually look like in practice? Two companies that are members of the Michigan Energy Innovation Business Council are potential examples.

• Energy Dome’s above ground compressed gas technology, the “CO2 Battery,” is a closed-loop system that holds carbon dioxide gas in a large dome structure. Using electricity from solar panels and wind turbines, this gas is heated and compressed into a liquid, which can be easily stored at room temperature. When discharging, the liquid is evaporated, and the resulting gas spins a turbine, generating electricity when needed, often with one full cycle per day (8+ hours of discharging). The company is currently constructing its first full-scale plant in Sardinia, Italy, with the project nearing completion. In the U.S., another plant is soon to follow, with project proponent Alliant Energy recently filing for regulatory approval of the Columbia Energy Storage Project in Wisconsin.
• Form Energy is commercializing a multi-day energy storage technology, a 100-hour duration iron-air battery for utility-scale applications. Essentially, the battery rusts and un-rusts iron to store and release electricity. Form Energy has constructed a new factory to manufacture these batteries domestically, and is working to deploy the first large-scale demonstrations of its technology with utilities like Great River Energy, Xcel Energy, Dominion and Georgia Power in 2025 and 2026.

A tremendous amount of innovative work will need to happen between now and the realization of the full potential for long-duration storage. There are a few things Michigan regulators should do with their study to best set up the state to reap the benefits from these emerging technologies:

First, the Commission should set clear targets for how much long-duration and multi-day storage utilities need to procure in coming years. Utilities are generally conservative and hesitant to pursue new technologies unless pushed or clearly allowed. But this problem is particularly heightened when it comes to long-duration storage. That’s because utilities, if given a megawatt target for storage they must deploy, will likely acquire storage without considering the benefits of having a diverse portfolio of technologies that can deliver energy over different durations. As a result, Michigan may lose out on the operational benefits that come from having a diversified storage portfolio. These benefits include the ability of long-duration storage to make firing up high-emitting, fossil-fuel-burning peaker plants unnecessary because the storage can provide more reliable, cleaner and cheaper alternatives. They also include overall cost and land-use savings, by storing renewable energy when it would otherwise be wasted and shifting it over long time periods when it is most needed.

Second, speaking of substitutes for fossil fuel plants, the Commission should identify which power plant sites around the state could be good candidates for being replaced with long-duration storage projects. Michigan’s coal-fired power plants are almost all retired, with Consumers Energy this year set to retire its final coal plant in Ottawa County. Long-duration storage could be fitting replacements for not only those plants, but also gas plants that will be reaching the end of their life cycles in coming years.

With its storage targets, Michigan has already become one of the national leaders in energy storage. Let’s further cement that reputation by taking steps now for smart planning for long-duration storage. All Michiganders stand to benefit from the potential for long-duration storage to enable an electric grid that is cleaner, lower-cost and more reliable.

Climate anxiety affects nearly half of young people aged 16-25. Students like second-year Rachel Mohammed find hope and inspiration through her involvement in innovative climate solutions, working alongside peers who share her determination. “I’ve met so many people at MIT who are dedicated to finding climate solutions in ways that I had never imagined, dreamed of, or heard of. That is what keeps me going, and I’m doing my part,” she says.

Hydrogen-fueled engines

Hydrogen offers the potential for zero or near-zero emissions, with the ability to reduce greenhouse gases and pollution by 29 percent. However, the hydrogen industry faces many challenges related to storage solutions and costs.

Mohammed leads the hydrogen team on MIT’s Electric Vehicle Team (EVT), which is dedicated to harnessing hydrogen power to build a cleaner, more sustainable future. EVT is one of several student-led build teams at the Edgerton Center focused on innovative climate solutions. Since its founding in 1992, the Edgerton Center has been a hub for MIT students to bring their ideas to life.

Hydrogen is mostly used in large vehicles like trucks and planes because it requires a lot of storage space. EVT is building their second iteration of a motorcycle based on what Mohammed calls a “goofy hypothesis” that you can use hydrogen to power a small vehicle. The team employs a hydrogen fuel cell system, which generates electricity by combining hydrogen with oxygen. However, the technology faces challenges, particularly in storage, which EVT is tackling with innovative designs for smaller vehicles.

Presenting at the 2024 World Hydrogen Summit reaffirmed Mohammed’s confidence in this project. “I often encounter skepticism, with people saying it’s not practical. Seeing others actively working on similar initiatives made me realize that we can do it too,” Mohammed says.

The team’s first successful track test last October allowed them to evaluate the real-world performance of their hydrogen-powered motorcycle, marking a crucial step in proving the feasibility and efficiency of their design.

MIT’s Sustainable Engine Team (SET), founded by junior Charles Yong, uses the combustion method to generate energy with hydrogen. This is a promising technology route for high-power-density applications, like aviation, but Yong believes it hasn’t received enough attention. Yong explains, “In the hydrogen power industry, startups choose fuel cell routes instead of combustion because gas turbine industry giants are 50 years ahead. However, these giants are moving very slowly toward hydrogen due to its not-yet-fully-developed infrastructure. Working under the Edgerton Center allows us to take risks and explore advanced tech directions to demonstrate that hydrogen combustion can be readily available.”

Both EVT and SET are publishing their research and providing detailed instructions for anyone interested in replicating their results.
