Fuel is out. Supply chains are in.
It was not long ago that the combination of “hydrogen” and “automakers” would bring to mind fuel cells, a technology that has already fallen out of favor as buyers flock to electric cars. In its wake, though, green hydrogen is catching the eye of automakers for another reason: It could allow them to decarbonize one of their trickiest supply chains.
In the last two years, major car companies have committed to integrating green or recycled steel, made with hydrogen, into their vehicles. At the forefront of this effort is Volvo, which aims to be the first automaker to use fossil-free steel in its cars. If successful — and, given where the company is in the process, that’s a big if — the Swedish automaker’s efforts could provide a template for how to decarbonize other challenging parts of industrial supply chains.
Steelmaking is responsible for roughly 8% of global energy demand and 2.6 gigatonnes of carbon dioxide emissions per year, a total higher than all of the European Union’s emissions in 2021. Steelmakers use fossil fuels — and especially highly polluting coal — to process iron ore and produce the alloy. At present, there aren’t any surefire paths to reduce these emissions, given how crucial a role steel plays in modern manufacturing.
But green steel has real promise. Hydrogen made using renewable energy can be used to replace coal in steelmaking with near-zero greenhouse gas emissions. The market for green steel is still small, though, in part because there is simply not a lot on offer. In 2019, just 8% of the world’s steel mills had even begun committing to zero-carbon technology, according to the green energy non-profit RMI.
This is largely because the supply of green hydrogen — the ingredient that gives green steel its name and a hot commodity among investors — is itself constrained. Creating the fuel is incredibly energy intensive. To produce 550 million metric tons of green hydrogen annually, the world would need 18 times more solar capacity than it has installed today, according to the Hydrogen Council.
As of 2020, the world demanded 90 million metric tons of hydrogen for refining and industrial applications, which were produced almost entirely by fossil fuels. Of that, just 30,000 metric tons were produced using renewable energy.
For Volvo, the first step of the enormous undertaking of steel decarbonization was to assess the carbon footprint of a car, specifically its first electric vehicle. It found its XC40 Recharge would emit 27 metric tons of carbon dioxide over its lifetime even if it were charged entirely using renewable energy. Of that total, 18% of the materials-related emissions came from the steel used to build the car.
According to Jonas Otterheim, who was until recently the head of climate action for the Swedish automaker (though he is temporarily on leave), this realization drove home that finding suppliers of low- or no-emissions steel would be “critical” to reach the company’s goal of supply chain-wide carbon neutrality by 2040.
Volvo turned to its steel suppliers, namely SSAB, the manufacturer that has long provided the company’s conventional steel. In June 2021, the two partnered to explore developing fossil-free steel for use in its cars as well.
It may seem that substituting green steel for conventional is straightforward, especially given that, per SSAB, “the only difference in the process is that the energy used will be exclusively fossil-free electricity and other fossil-free fuels.” However, with an operation as complicated as auto manufacturing, any material change requires exhaustive testing.
And that’s where Volvo is today. The automaker aims to integrate green steel into its vehicles in 2026, which is when SSAB intends to have its fossil-free plant up and running. In the meantime, Volvo is evaluating “part-by-part” which components of its manufacturing process can safely be replaced with green steel.
“This is [a] very big job over a number of years, before the material can be put into any car,” said Otterheim. The two companies are evaluating whether the switch to green steel will require retooling its plants, which “are built specifically for every car and every material quality we have,” he added.
Otterheim said the deal initially was just exploratory in nature: an opportunity for both companies to explore whether it’s possible to make fossil-free versions of all the different grades of steel that are necessary to build a car, and potentially use it in a concept car.
However, his colleague Stina Klingvall, who is Volvo’s acting head of climate action in Otterheim’s absence, said that things have developed to the point where Volvo is actively starting to prepare to produce components with the new steel.
One promising development has come already from within the Volvo ecosystem. In August 2021, SSAB shipped a batch of green steel made at a pilot plant with renewable electricity and hydrogen to Volvo’s truck-making arm (separate from Volvo Cars), which was then integrated the steel into a dump truck prototype. (SSAB produced this steel under its Hybrit initiative, a collaboration with mining company LKAB and power company Vattenfall.)
One big outstanding question is how much automakers and other green steel buyers will have to pay to use the more sustainable metal.
RMI’s analysis found that hydrogen-based steel production can result in a 20% cost premium, but also that the premium disappears when electricity prices are in the range of $15-$20 per megawatt-hour or lower. This remains out of reach across most of the U.S., though a Lawrence Berkeley National Laboratory study found that the country is on track for solar costing $22 per MWh hour on average by 2035 (down from $34 per MWh in 2020).
Meanwhile, Otterheim said that he hopes that Volvo’s work will “help drive down costs'' to be more in line with the status quo for steel, and that it will push more automakers to make commitments of their own. This represents the most crucial knock-on effect of a single company’s dipping a toe into greener materials: peer pressure.
“Due to the scarcity of these materials over the short-term period, other premium car makers are also starting to act to secure volumes for their supply,” Otterheim said. “The race for such materials is naturally good, creating an even stronger signal to other steel suppliers to follow.”
Volvo may have made the first green steel purchase commitment, but several automaker competitors have followed suit, including BMW and General Motors. While the pool of customers for steel is a big one (and includes the renewables industry), transportation is a particularly big fish in that pool, responsible for 12% of global steel consumption, per the World Steel Association.
When it comes to urging heavy industry to decarbonize, there is strength in numbers. Materials like steel, cement, and chemicals are integral parts of countless other supply chains, which means it’s hard for a single customer to have much sway. As a consequence, heavy industrial companies lack the incentive to innovate, said former New York Times journalist Justin Gillis, who recently published a book on how to push for climate action. There are few market signals “that clean products are going to be favored,” he said.
But some companies are trying to change that dynamic. The First Movers Coalition was formed last year explicitly to create markets for nascent sectors like green steel and carbon dioxide removal. With a market cap of $8.5 trillion between the more than 50 companies involved, their collective pledges to procure climate-friendly products despite the higher price tag offers market certainty. When Ford joined the coalition in May, the company pledged that at least 10% of its steel and aluminum would have near-zero carbon emissions by 2030.
Ultimately, companies that have committed to cleaning up their supply chains have a choice of how to decide to define that supply chain, and how much pressure to put on their suppliers with hard-to-abate emissions.
“How many steps back in the supply chain do you go? The further back you go, the less responsibility any one consumer-facing company can have,” Gillis said. “I do think these companies can play a role by sending market pressure, but they need to be willing to pay a price premium for cleaner supplies or materials.”

Why killing a government climate database could essentially gut a tax credit
The Trump administration’s bid to end an Environmental Protection Agency program may essentially block any company — even an oil firm — from accessing federal subsidies for capturing carbon or producing hydrogen fuel.
On Friday, the Environmental Protection Agency proposed that it would stop collecting and publishing greenhouse gas emissions data from thousands of refineries, power plants, and factories across the country.
The Trump administration argues that the scheme, known as the Greenhouse Gas Reporting Program, costs more than $2 billion and isn’t legally required under the Clean Air Act. Lee Zeldin, the EPA administrator, described the program as “nothing more than bureaucratic red tape that does nothing to improve air quality.”
But the program is more important than the Trump administration lets on. It’s true that the policy, which required more than 8,000 different facilities around the country to report their emissions, helped the EPA and outside analysts estimate the country’s annual greenhouse gas emissions.
But it did more than that. Over the past decade, the program had essentially become the master database of carbon pollution and emissions policy across the American economy. “Essentially everything the federal government does related to emissions reductions is dependent on the [Greenhouse Gas Reporting Program],” Jack Andreasen Cavanaugh, a fellow at the Center on Global Energy Policy at Columbia University, told me.
That means other federal programs — including those that Republicans in Congress have championed — have come to rely on the EPA database.
Among those programs: the federal tax credit for capturing and using carbon dioxide. Republicans recently increased the size of that subsidy, nicknamed 45Q after a section of the tax code, for companies that turn captured carbon into another product or use it to make oil wells more productive. Those changes were passed in President Trump’s big tax and spending law over the summer.
But Zeldin’s scheme to end the Greenhouse Gas Reporting Program would place that subsidy off limits for the foreseeable future. Under federal law, companies can only claim the 45Q tax credit if they file technical details to the EPA’s emissions reporting program.
Another federal tax credit, for companies that use carbon capture to produce hydrogen fuel, also depends on the Greenhouse Gas Reporting Program. That subsidy hasn’t received the same friendly treatment from Republicans, and it will now phase out in 2028.
The EPA program is “the primary mechanism by which companies investing in and deploying carbon capture and hydrogen projects quantify the CO2 that they’re sequestering, such that they qualify for tax incentives,” Jane Flegal, a former Biden administration appointee who worked on industrial emissions policy, told me. She is now the executive director of the Blue Horizons Foundation.
“The only way for private capital to be put to work to deploy American carbon capture and hydrogen projects is to quantify the carbon dioxide that they’re sequestering, in some way,” she added. That’s what the EPA program does: It confirms that companies are storing or using as much carbon as they claim they are to the IRS.
The Greenhouse Gas Reporting Program is “how the IRS communicates with the EPA” when companies claim the 45Q credit, Cavanaugh said. “The IRS obviously has taxpayer-sensitive information, so they’re not able to give information to the EPA about who or what is claiming the credit.” The existence of the database lets the EPA then automatically provide information to the IRS, so that no confidential tax information is disclosed.
Zeldin’s announcement that the EPA would phase out the program has alarmed companies planning on using the tax credit. In a statement, the Carbon Capture Coalition — an alliance of oil companies, manufacturers, startups, and NGOs — called the reporting program the “regulatory backbone” of the carbon capture tax credit.
“It is not an understatement that the long-term success of the carbon management industry rests on the robust reporting mechanisms” in the EPA’s program, the group said.
Killing the EPA program could hurt American companies in other ways. Right now, companies that trade with European firms depend on the EPA data to pass muster with the EU’s carbon border adjustment tax. It’s unclear how they would fare in a world with no EPA data.
It could also sideline GOP proposals. Senator Bill Cassidy, a Republican from Louisiana, has suggested that imports to the United States should pay a foreign pollution fee — essentially, a way of accounting for the implicit subsidy of China’s dirty energy system. But the data to comply with that law would likely come from the EPA’s greenhouse gas database, too.
Ending the EPA database wouldn’t necessarily spell permanent doom for the carbon capture tax credit, but it would make it much harder to use in the years to come. In order to re-open the tax credit for applications, the Treasury Department, the Energy Department, the Interior Department, and the EPA would have to write new rules for companies that claim the 45Q credit. These rules would go to the end of the long list of regulations that the Treasury Department must write after Trump’s spending law transformed the tax code.
That could take years — and it could sideline projects now under construction. “There are now billions of dollars being invested by the private sector and the government in these technologies, where the U.S. is positioned to lead globally,” Flegal said. Changing the rules would “undermine any way for the companies to succeed.”
Ditching the EPA database, however, very well could doom carbon capture-based hydrogen projects. Under the terms of Trump’s tax law, companies that want to claim the hydrogen credit must begin construction on their projects by 2028.
The Trump administration seems to believe, too, that gutting the EPA database may require new rules for the carbon capture tax credit. When asked for comment, an EPA spokesperson pointed me to a line in the agency’s proposal: “We anticipate that the Treasury Department and the IRS may need to revise the regulation,” the legal proposal says. “The EPA expects that such amendments could allow for different options for stakeholders to potentially qualify for tax credits.”
The EPA spokesperson then encouraged me to ask the Treasury Department for anything more about “specific implications.”
Paradise, California, is snatching up high-risk properties to create a defensive perimeter and prevent the town from burning again.
The 2018 Camp Fire was the deadliest wildfire in California’s history, wiping out 90% of the structures in the mountain town of Paradise and killing at least 85 people in a matter of hours. Investigations afterward found that Paradise’s town planners had ignored warnings of the fire risk to its residents and forgone common-sense preparations that would have saved lives. In the years since, the Camp Fire has consequently become a cautionary tale for similar communities in high-risk wildfire areas — places like Chinese Camp, a small historic landmark in the Sierra Nevada foothills that dramatically burned to the ground last week as part of the nearly 14,000-acre TCU September Lightning Complex.
More recently, Paradise has also become a model for how a town can rebuild wisely after a wildfire. At least some of that is due to the work of Dan Efseaff, the director of the Paradise Recreation and Park District, who has launched a program to identify and acquire some of the highest-risk, hardest-to-access properties in the Camp Fire burn scar. Though he has a limited total operating budget of around $5.5 million and relies heavily on the charity of local property owners (he’s currently in the process of applying for a $15 million grant with a $5 million match for the program) Efseaff has nevertheless managed to build the beginning of a defensible buffer of managed parkland around Paradise that could potentially buy the town time in the case of a future wildfire.
In order to better understand how communities can build back smarter after — or, ideally, before — a catastrophic fire, I spoke with Efseaff about his work in Paradise and how other communities might be able to replicate it. Our conversation has been lightly edited and condensed for clarity.
Do you live in Paradise? Were you there during the Camp Fire?
I actually live in Chico. We’ve lived here since the mid-‘90s, but I have a long connection to Paradise; I’ve worked for the district since 2017. I’m also a sea kayak instructor and during the Camp Fire, I was in South Carolina for a training. I was away from the phone until I got back at the end of the day and saw it blowing up with everything.
I have triplet daughters who were attending Butte College at the time, and they needed to be evacuated. There was a lot of uncertainty that day. But it gave me some perspective, because I couldn’t get back for two days. It gave me a chance to think, “Okay, what’s our response going to be?” Looking two days out, it was like: That would have been payroll, let’s get people together, and then let’s figure out what we’re going to do two weeks and two months from now.
It also got my mind thinking about what we would have done going backwards. If you’d had two weeks to prepare, you would have gotten your go-bag together, you’d have come up with your evacuation route — that type of thing. But when you run the movie backwards on what you would have done differently if you had two years or two decades, it would include prepping the landscape, making some safer community defensible space. That’s what got me started.
Was it your idea to buy up the high-risk properties in the burn scar?
I would say I adapted it. Everyone wants to say it was their idea, but I’ll tell you where it came from: Pre-fire, the thinking was that it would make sense for the town to have a perimeter trail from a recreation standpoint. But I was also trying to pitch it as a good idea from a fuel standpoint, so that if there was a wildfire, you could respond to it. Certainly, the idea took on a whole other dimension after the Camp Fire.
I’m a restoration ecologist, so I’ve done a lot of river floodplain work. There are a lot of analogies there. The trend has been to give nature a little bit more room: You’re not going to stop a flood, but you can minimize damage to human infrastructure. Putting levees too close to the river makes them more prone to failing and puts people at risk — but if you can set the levee back a little bit, it gives the flood waters room to go through. That’s why I thought we need a little bit of a buffer in Paradise and some protection around the community. We need a transition between an area that is going to burn, and that we can let burn, but not in a way that is catastrophic.
How hard has it been to find willing sellers? Do most people in the area want to rebuild — or need to because of their mortgages?
Ironically, the biggest challenge for us is finding adequate funding. A lot of the property we have so far has been donated to us. It’s probably upwards of — oh, let’s see, at least half a dozen properties have been donated, probably close to 200 acres at this point.
We are applying for some federal grants right now, and we’ll see how that goes. What’s evolved quite a bit on this in recent years, though, is that — because we’ve done some modeling — instead of thinking of the buffer as areas that are managed uniformly around the community, we’re much more strategic. These fire events are wind-driven, and there are only a couple of directions where the wind blows sufficiently long enough and powerful enough for the other conditions to fall into play. That’s not to say other events couldn’t happen, but we’re going after the most likely events that would cause catastrophic fires, and that would be from the Diablo winds, or north winds, that come through our area. That was what happened in the Camp Fire scenario, and another one our models caught what sure looked a lot like the [2024] Park Fire.
One thing that I want to make clear is that some people think, “Oh, this is a fire break. It’s devoid of vegetation.” No, what we’re talking about is a well-managed habitat. These are shaded fuel breaks. You maintain the big trees, you get rid of the ladder fuels, and you get rid of the dead wood that’s on the ground. We have good examples with our partners, like the Butte Fire Safe Council, on how this works, and it looks like it helped protect the community of Cohasset during the Park Fire. They did some work on some strips there, and the fire essentially dropped to the ground before it came to Paradise Lake. You didn’t have an aerial tanker dropping retardant, you didn’t have a $2-million-per-day fire crew out there doing work. It was modest work done early and in the right place that actually changed the behavior of the fire.
Tell me a little more about the modeling you’ve been doing.
We looked at fire pathways with a group called XyloPlan out of the Bay Area. The concept is that you simulate a series of ignitions with certain wind conditions, terrain, and vegetation. The model looked very much like a Camp Fire scenario; it followed the same pathway, going towards the community in a little gulch that channeled high winds. You need to interrupt that pathway — and that doesn’t necessarily mean creating an area devoid of vegetation, but if you have these areas where the fire behavior changes and drops down to the ground, then it slows the travel. I found this hard to believe, but in the modeling results, in a scenario like the Camp Fire, it could buy you up to eight hours. With modern California firefighting, you could empty out the community in a systematic way in that time. You could have a vigorous fire response. You could have aircraft potentially ready. It’s a game-changing situation, rather than the 30 minutes Paradise had when the Camp Fire started.
How does this work when you’re dealing with private property owners, though? How do you convince them to move or donate their land?
We’re a Park and Recreation District so we don’t have regulatory authority. We are just trying to run with a good idea with the properties that we have so far — those from willing donors mostly, but there have been a couple of sales. If we’re unable to get federal funding or state support, though, I ultimately think this idea will still have to be here — whether it’s five, 10, 15, or 50 years from now. We have to manage this area in a comprehensive way.
Private property rights are very important, and we don’t want to impinge on that. And yet, what a person does on their property has a huge impact on the 30,000 people who may be downwind of them. It’s an unusual situation: In a hurricane, if you have a hurricane-rated roof and your neighbor doesn’t, and theirs blows off, you feel sorry for your neighbor but it’s probably not going to harm your property much. In a wildfire, what your neighbor has done with the wood, or how they treat vegetation, has a significant impact on your home and whether your family is going to survive. It’s a fundamentally different kind of event than some of the other disasters we look at.
Do you have any advice for community leaders who might want to consider creating buffer zones or something similar to what you’re doing in Paradise?
Start today. You have to think about these things with some urgency, but they’re not something people think about until it happens. Paradise, for many decades, did not have a single escaped wildfire make it into the community. Then, overnight, the community is essentially wiped out. But in so many places, these events are foreseeable; we’re just not wired to think about them or prepare for them.
Buffers around communities make a lot of sense, even from a road network standpoint. Even from a trash pickup standpoint. You don’t think about this, but if your community is really strung out, making it a little more thoughtfully laid out also makes it more economically viable to provide services to people. Some things we look for now are long roads that don’t have any connections — that were one-way in and no way out. I don’t think [the traffic jams and deaths in] Paradise would have happened with what we know now, but I kind of think [authorities] did know better beforehand. It just wasn’t economically viable at the time; they didn’t think it was a big deal, but they built the roads anyway. We can be doing a lot of things smarter.
A war of attrition is now turning in opponents’ favor.
A solar developer’s defeat in Massachusetts last week reveals just how much stronger project opponents are on the battlefield after the de facto repeal of the Inflation Reduction Act.
Last week, solar developer PureSky pulled five projects under development around the western Massachusetts town of Shutesbury. PureSky’s facilities had been in the works for years and would together represent what the developer has claimed would be one of the state’s largest solar projects thus far. In a statement, the company laid blame on “broader policy and regulatory headwinds,” including the state’s existing renewables incentives not keeping pace with rising costs and “federal policy updates,” which PureSky said were “making it harder to finance projects like those proposed near Shutesbury.”
But tucked in its press release was an admission from the company’s vice president of development Derek Moretz: this was also about the town, which had enacted a bylaw significantly restricting solar development that the company was until recently fighting vigorously in court.
“There are very few areas in the Commonwealth that are feasible to reach its clean energy goals,” Moretz stated. “We respect the Town’s conservation go als, but it is clear that systemic reforms are needed for Massachusetts to source its own energy.”
This stems from a story that probably sounds familiar: after proposing the projects, PureSky began reckoning with a burgeoning opposition campaign centered around nature conservation. Led by a fresh opposition group, Smart Solar Shutesbury, activists successfully pushed the town to drastically curtail development in 2023, pointing to the amount of forest acreage that would potentially be cleared in order to construct the projects. The town had previously not permitted facilities larger than 15 acres, but the fresh change went further, essentially banning battery storage and solar projects in most areas.
When this first happened, the state Attorney General’s office actually had PureSky’s back, challenging the legality of the bylaw that would block construction. And PureSky filed a lawsuit that was, until recently, ongoing with no signs of stopping. But last week, shortly after the Treasury Department unveiled its rules for implementing Trump’s new tax and spending law, which basically repealed the Inflation Reduction Act, PureSky settled with the town and dropped the lawsuit – and the projects went away along with the court fight.
What does this tell us? Well, things out in the country must be getting quite bleak for solar developers in areas with strident and locked-in opposition that could be costly to fight. Where before project developers might have been able to stomach the struggle, money talks – and the dollars are starting to tell executives to lay down their arms.
The picture gets worse on the macro level: On Monday, the Solar Energy Industries Association released a report declaring that federal policy changes brought about by phasing out federal tax incentives would put the U.S. at risk of losing upwards of 55 gigawatts of solar project development by 2030, representing a loss of more than 20 percent of the project pipeline.
But the trade group said most of that total – 44 gigawatts – was linked specifically to the Trump administration’s decision to halt federal permitting for renewable energy facilities, a decision that may impact generation out west but has little-to-know bearing on most large solar projects because those are almost always on private land.
Heatmap Pro can tell us how much is at stake here. To give you a sense of perspective, across the U.S., over 81 gigawatts worth of renewable energy projects are being contested right now, with non-Western states – the Northeast, South and Midwest – making up almost 60% of that potential capacity.
If historical trends hold, you’d expect a staggering 49% of those projects to be canceled. That would be on top of the totals SEIA suggests could be at risk from new Trump permitting policies.
I suspect the rate of cancellations in the face of project opposition will increase. And if this policy landscape is helping activists kill projects in blue states in desperate need of power, like Massachusetts, then the future may be more difficult to swallow than we can imagine at the moment.
