Advocates make economic case for green steel production at Dearborn, Michigan plant

Dearborn, Michigan, was at the heart of auto industry innovation during the days of the Model T Ford. 

Now clean energy and environmental justice advocates are proposing that the city play a lead role in greening the auto industry, through a transformation of the Dearborn Works steel mill to “green steel” — a steelmaking process powered by hydrogen and renewable energy with drastically lower emissions than a traditional blast furnace. 

The blast furnace at Dearborn Works is due for relining in 2027, at an estimated cost of $470 million. Advocates argue that instead of prolonging the blast furnace’s life, its owner, Cleveland Cliffs, should invest another $2 billion dollars and convert the mill to Direct Reduced Iron (DRI) technology powered by green hydrogen (hydrogen produced with renewable energy).

An October report by Dr. Elizabeth Boatman of the firm 5 Lakes Energy examines the economics and logistics of such a conversion, and argues that demand for cleaner steel is likely to grow as auto companies and other global industries seek to lower their greenhouse gas footprints. Starting in 2026, steel importers to the European Union will need to make payments to offset emissions associated with steel production.

Worldwide, the auto industry is the second largest consumer of steel after construction, and “being able to pass on the price of a ‘green steel premium’ to its end consumers, the automotive industry is uniquely positioned to create demand for green steel without having to rely on public subsidies,” the European Union think tank CEPS said in a recent publication.

“This is a great chance for the state to step in now and ensure this conversion happens, instead of waiting another 20 years,” said Boatman. “All the economic indicators suggest clean steel is the steel product of the future, and the best way to future-proof jobs especially in the steel sector and especially for unions.” 

Cutting pollution, creating jobs 

Cleveland Cliffs is planning to convert its Middletown, Ohio, steel mill to DRI, tapping a $500 million federal grant for industrial decarbonization under the Bipartisan Infrastructure Law and Inflation Reduction Act. 

A DRI furnace does not need to use coke or heat iron ore to 3,000 degrees Fahrenheit to produce pure “pig iron”; the same result is achieved with a different chemical process at much lower temperatures. DRI furnaces can be powered by natural gas or clean hydrogen. Initially, Cleveland Cliffs says, its Middletown mill will run on natural gas, releasing about half the carbon emissions of its current blast furnace. Eventually, the company announced, it could switch to hydrogen. 

Along with slashing greenhouse gas emissions, a similar green steel conversion at Dearborn Works would greatly reduce the local air pollution burden facing local residents in the heavily industrial area, which is also home to a Marathon oil refinery, a major rail yard and other polluters.    

But it wouldn’t be cheap. Boatman’s report estimated the cost of converting a blast furnace to a DRI furnace and associated electric arc furnaces at $1.57 billion, plus $2.6 billion to build a green hydrogen plant. Utility DTE Energy would need to work with grid operator MISO to add about 2 GW of solar and 2 GW of wind power, plus battery storage, to the grid to power the green hydrogen production. 

The conversion would mean closure of the EES Coke plant, which turns coal into coke for the steel mill, on heavily polluted Zug Island in the River Rouge just outside Detroit, five miles from Dearborn. In 2022, the EPA sued the coke plant, a subsidiary of DTE Energy, over Clean Air Act violations. 

A recent study by the nonprofit Industrious Labs found that the EES Coke plant could be responsible for up to 57 premature deaths and more than 15,000 asthma attacks. The report also found that more than half the people living within a three-mile radius of both the steel mill and coke plant are low-income, and three-quarters of those living around the coke plant are people of color, as are half those living around the steel mill. 

“The total health costs are quite significant,” said Nick Leonard, executive director of the Great Lakes Environmental Law Center, which is representing local residents as intervenors in the EPA lawsuit against the coke plant. “We allow companies to externalize those costs and not account for them. If they were required by some sort of change in policy or regulation to be responsible for those costs, it would certainly make the case they could make this expensive switch” to green steel. 

The law center also represented residents in legal proceedings around Dearborn Works’ Clean Air Act violations, including a 2015 consent decree and a 2023 mandate to install a new electrostatic precipitator at a cost of $100 million. 

Leonard said local residents “know Cleveland Cliffs poses a risk to their health, and they want solutions. They know there’s a problem, they are frustrated by the lack of will or attention from state and local government.”

Cleveland Cliffs did not respond to a request for comment. 

Why Michigan? 

The country’s active steel mills are concentrated in Pennsylvania, Indiana, Ohio and Michigan. Advocates and residents are asking Nippon Steel to consider a green steel conversion at the Gary Works mill in Northwest Indiana, if the global corporation succeeds in acquiring Gary Works owner U.S. Steel. Advocates have also proposed green steel conversions for Pennsylvania mills. 

There are factors that make a green steel conversion both more promising and more challenging at Dearborn Works, compared to other locations, Boatman explained. 

Dearborn Works has only one blast furnace in operation, meaning a potentially smaller investment than at mills with more furnaces. Michigan has also set aggressive renewable energy goals, which could be furthered by the ambitious renewable energy buildout that would be required to produce enough green hydrogen for the steel mill.

“That’s why we’re asking the state of Michigan and the governor to get all the interested parties to the table to actually talk about this, hopefully commit to it, and do the detailed planning that needs to be done to figure out how much wind, how much solar, how much battery storage does there need to be to get this off the ground,” said Boatman. 

Michigan has legal limits on behind-the-meter generation that could make it more difficult to build renewables specifically to power green hydrogen production for a steel mill. Utilities would instead need to produce or procure the renewable energy, and sell it to the steel mill, Boatman explained.

A green steel conversion at Dearborn Works could create a total of about 500 new jobs, Boatman estimates, considering that about 500 jobs would be lost at the closing coke plant but 410 jobs would be created at the hydrogen plant, 550 in new renewables and 170 at the mill itself. The DRI conversion at the Middletown steel mill is expected to create 170 new permanent jobs and 1,200 construction jobs, according to Cleveland Cliffs. 

A 2023 analysis by the Ohio River Valley Institute found that at the Mon Valley Works steel mill in Pennsylvania, a DRI conversion would likely preserve more iron- and steel-making jobs than “business as usual,” with 87% of the current jobs expected to exist in 2031, compared to 69% without a change — as U.S. steel production continues to shrink and automate. 

“We are seeing a general trend for both iron and [secondary] steel production to move toward the South, to states that aren’t friendly to unions and can produce products at cheaper prices by bypassing unions,” said Boatman. “Michigan obviously has a proud history of being a strong union state, it matters to keep those good union jobs there.” 

Labor unions have largely been silent on the concept of green steel conversion. The United Auto Workers union — which represents Dearborn Works employees — and the United Steelworkers did not respond to requests for comment. 

Hydrogen wild cards 

The U.S. Department of Energy plans to spend $8 billion on hydrogen hubs, and a potentially lucrative tax credit known as 45V is being finalized for clean hydrogen. Experts and advocates agree that energy-intensive, hard-to-decarbonize industries like steel are where hydrogen could have the most impact. But large-scale production of pure hydrogen for industrial use is still in nascent stages, and little infrastructure has been built or tested for transporting and storing hydrogen. 

That is among the reasons, Boatman said, that there’s been reluctance among residents and union leaders to embrace the concept of green steel. Boatman’s report emphasizes that community benefits agreements and community engagement processes are crucial to make sure residents are informed about, benefit from, and have a meaningful voice in any green steel plans. 

“Union workers and fence-line community members all want better air quality, lower emissions, who wouldn’t want to go to work knowing you’re safer being there?” she said. “There’s a lot of interest in cleaning up the air. It’s more a question over how that happens. When hydrogen becomes part of the equation, there’s always some concern.” 

She noted that hydrogen could potentially be stored in salt caverns in the Detroit area, though extensive study on the feasibility and environmental impacts would be needed. In Mississippi, a startup company Hy Stor Energy is planning to store green hydrogen in salt caverns, ready to generate electricity during times of high demand. 

Tax incentives for clean hydrogen could provide major incentives for steel mills. But clean hydrogen proposed projects have been in flux nationwide as the rules for qualifying for 45V tax credits are being hashed out in a lengthy, controversial process; and the change in presidential administration adds even more uncertainty. 

“These industries have to be incentivized,” said Roxana Bekemohammadi, founder and executive director of the U.S. Hydrogen Alliance, which advocates for pro-hydrogen policies on the state level. “Europe is creating a mandate — that’s one incentive. We’d love to support any incentives that would allow hydrogen to be leveraged in the steel industry. With state legislation we certainly can incentivize it. It’s a question of how competitive we want to be.”

Steelmaker’s bid to buy U.S. Steel would extend life of Indiana plant — along with its emissions

22 October 2024 at 10:01

A prospective buyer’s recent commitment to reinvest in a Gary, Indiana, steel plant sought to address union and government leaders’ worries about the sale’s potential impact on jobs and U.S. steelmaking capacity.

The plan to extend the life of the country’s largest and most carbon-emitting coal-fired blast furnace, however, has also heightened concerns from Northwest Indiana residents most affected by the facility’s air pollution.

“This is not acceptable,” said Susan Thomas, director of legislation and policy for Just Transition Northwest Indiana. “We now have technology for doing this much more sustainably.”

A study released Monday quantifies the public health threat highlighted by local clean air advocates, linking the Indiana plant to dozens of annual emergency room visits and premature deaths, as well as thousands of asthma attacks. 

Japan-based Nippon Steel is seeking approval from U.S. regulators for a $15 billion acquisition of U.S. Steel, the storied domestic steelmaker whose facilities include the Gary Works plant in Northwest Indiana, along with others in Ohio, Michigan and Pennsylvania, key battleground states where the proposed sale has been a subject of presidential campaigning. Vice President Kamala Harris and former President Donald Trump oppose the sale, as does President Joe Biden.

Much of the public discussion around the proposed sale has centered on its economic and national security implications, but those living near the plant have different concerns and demands. They say they’ve suffered for too long from steel industry pollution, and they only want Nippon as a neighbor if the company installs a new type of furnace that burns with lower or even zero emissions. 

“I would love to see Gary Works transform to green sustainable steel, bringing more jobs, cleaning up the area, that would be an amazing win-win,” said Libré Booker, a librarian who grew up near the mill. “The people have lived under these conditions for far too long. It’s definitely time for a change.”

Gary Works is the largest integrated steel mill in North America, employing about 2,200 people. Northwest Indiana is also home to two other steel mills — Burns Harbor and Indiana Harbor — and two coke plants that turn coal into the high-density raw material for steel. 

The populations in a three-mile radius of the Gary Works and Indiana Harbor steel mills are 96%-97% people of color, and almost two-thirds low-income people. The new study by Industrious Labs, a nonprofit focused on emissions reduction, used the EPA’s COBRA model to find emissions from the Gary Works plant likely are linked to 57-114 premature deaths, 48 emergency room visits and almost 32,000 asthma attacks each year.

The report cited the mills’ and coke plants’ emissions of sulfur dioxide, nitrogen oxides, carbon monoxide, particulate matter, and lead, all pollutants with direct impacts on public health. Gary Works is the number one emitter of PM2.5 particulate matter in the state, according to the company’s self-reported data analyzed by Industrious Labs. 

Industrious Labs steel director Hilary Lewis said the results bolster the demands of clean steel advocates, who want to see coal-fired blast furnaces replaced by direct-reduction iron, or DRI, furnaces powered by hydrogen made with renewable energy, known as green hydrogen. 

Booker was among 15 locals who participated in a recent “Sustainable Steel Community Cohort” run by Industrious Labs, attending five workshops learning about the science and policy of cleaner steel. 

Green hydrogen, green steel 

Green hydrogen is still not produced in large quantities anywhere in the U.S., and all the hydrogen currently produced in the country would not even be enough to power one steel mill, noted Seth Snyder, a partner in the Clean Energy Venture Group, at a recent conference in Chicago focused on clean hydrogen. 

But DRI furnaces can be powered by natural gas, which results in much lower emissions than coal. Cleveland Cliffs — which owns the Indiana Harbor and Burns Harbor mills — is transforming its Middletown, Ohio steel mill to gas-burning DRI with the help of a $500 million incentive under the Inflation Reduction Act. The company says the conversion will make it the steel mill with the lowest emissions in the world. 

With some modifications, DRI furnaces can burn a blend of natural gas and hydrogen or almost entirely hydrogen, experts say, meaning investment in a gas-burning DRI furnace could be a step on the way to “clean steel.” Lewis and other advocates, however, say gas-burning furnaces are not their goal, and they want the industry to transition off fossil fuels entirely. 

Hydrogen can be blended into fuel for traditional blast furnaces too, but the maximum emissions reductions that can be achieved that way are 21%, according to a paper on hydrogen-powered steel production in Europe by the Norwegian non-profit science organization Bellona. 

Nippon has announced it would invest $300 million in restoring the aging blast furnace at Gary Works, keeping it running for another 20 years. Installing a DRI furnace, meanwhile, typically costs over $1 billion.

“There is a gap,” said Lewis. “But these companies have the funding available. They have the money to make these decisions, they’re just choosing not to.” 

Incentives for change 

The IRA incentives tapped by Cleveland Cliffs are no longer available, but this summer California U.S. Rep. Ro Khanna introduced the Modern Steel Act, which would provide $10 billion in low-cost loans and grants, plus tax breaks and other incentives for new and revamped low-emissions steel mills, including hydrogen-fueled DRI.

Separately, lucrative tax credits soon to be available for “clean hydrogen” under the IRA could also make hydrogen-powered steel more financially viable. The specific rules for the tax credit — known as 45V — are still being finalized, amid controversy over what should qualify a project’s hydrogen as “clean.” 

“There are a number of different incentives in the IRA that can help steel companies build out their own green hydrogen infrastructure,” Lewis said. “Everything should be on the table. Steel companies would be such huge off-takers for green hydrogen, they can build their own economy here.”

At the BP Whiting oil refinery, 10 miles from Gary Works, there are plans underway for production of blue hydrogen, or hydrogen made with natural gas followed by capture and sequestration of the emissions. The plan is a marquee part of the Midwest (MachH2) hydrogen hub, one of seven planned hubs nationwide slated to receive $7 billion total in federal funding. Such blue hydrogen could be used to power a steel mill, with theoretically no resulting greenhouse gas or public health-harming emissions.

However, local environmental and public accountability leaders are strongly opposed to blue hydrogen production in the region, since carbon sequestration has not yet been done successfully on a large scale in the U.S., and it would entail pipelines carrying carbon dioxide from the refinery to a sequestration site. 

“The carbon capture component makes us very nervous, it seems to me they’re rushing into this without really taking the time to study it more seriously,” said Northwest Indiana resident Connie Wachala, another graduate of the sustainable steel program. “That might be because of all the money DOE is making available to industry. I wish our elected and industry officials would start thinking more creatively about how to make [green hydrogen] happen, how to make things better for the people in the neighborhoods and around the steel mills as well as for the shareholders.”

A different future 

All four of Wachala’s grandparents came from Poland to work in the steel mills. 

“Growing up in the 1950s, I remember my mom hanging the laundry up in the yard on a clothes line. If the wind was blowing a certain way, you’d get black particles on the clothes,” remembered Wachala, who worked as a creative writing teacher before retiring. “My dad’s car was always covered with that soot.”

Booker’s mother worked as a crane operator at the now-closed Bethlehem Steel mill in Burns Harbor, Indiana — among the first wave of women of color to be hired.

“I was proud she worked in the mill and took care of us, but I did not want [that job] whatsoever, seeing her come home every night after the swing shift, with the big old boots and jacket,” said Booker. “I wanted to go to college. It was a source of contention with my mom and I for some years.” 

That was in the days when locals largely believed, “if you want a good partner, you’ve got to get one that works in the mill,” she continued. “It was like a prestigious job and position. People looked up to people who worked in the mill.” 

Now, Booker laments, “Gary is like a joke,” scorned for its economic decline since the steel industry automated and shrunk — hemorrhaging jobs, and for the pollution that is still emitted. If the merger with Nippon does not go through, it’s widely believed U.S. Steel would eventually close the mill, as it closed its South Works plant in Southeast Chicago decades ago. At their height, the South Works and Gary Works plants together employed about 40,000 people in the Chicago area. 

Thomas wrote a frustrated rebuttal to the Chicago Tribune editorial board opining that the Nippon merger was crucial to Gary’s future. She and other local leaders say they don’t want the mill to close, but they can demand better than the extension of heavily polluting industry. 

“It’s just perpetuation of this as a sacrifice zone,” said Thomas. “‘This is what you’ve always been, this is how we’re going to keep you.’ But that’s not going to fly anymore.”
