Not even the companies that — on the surface, at least — seem most likely to benefit from them.
Amidst the chaos of President Donald Trump’s tariff regime so far, there has been one constant — the 25% levies on steel and aluminum imports applied in February, with no country-specific exemptions. I’ve been a bit befuddled as to what these tariffs may, or may not, mean for the companies trying to green these notoriously hard-to-decarbonize sectors. And it turns out, some of them are a bit befuddled, too.
“It’s a mixed bag,” Cody Finke, CEO of the Bay Area-based clean cement and alumina startup Brimstone told me. Brimstone’s core breakthrough is figuring out a way to co-produce cement and alumina — the core material in the critical mineral aluminum — using carbon-free calcium silicates such as basalt rather than limestone, which releases a lot of CO2 when it’s processed.
At least on the surface, a company like Brimstone should fall squarely among the beneficiaries of Trump’s trade policy — the whole point of the tariffs, after all, is to increase demand for domestic steel and aluminum by making foreign metals more expensive. That will likely allow U.S.-based producers to raise prices, too, generating even more revenue.
Then again, green steel and aluminum producers rely on imports of these same materials to build their own plants. Tariffs on these vital construction materials — plus exorbitant levies on all goods from China — will make building new production facilities significantly costlier. (As Keith Norman, CEO of the domestic battery manufacturer Lyten told me last month, “The reality is, the energy transition is a manufacturing transition.”) Not to mention the fact that the auto industry — a heavy user of both steel and aluminum — is facing its own 25% tariffs on imported vehicles and auto parts. That stands to raise the price and thus lower the demand for cars, in turn reducing demand for the materials needed to build them, green or not.
Large industry players such as Nucor and Cleveland Cliffs — both of which have plans to produce green steel — have seen mixed responses since the tariffs were announced. “Nucor recently said on an earnings call that they have huge backlogs, suggesting increased demand. [Cleveland] Cliffs, on the other hand, is idling plants due to low demand,” Hilary Lewis, the steel director at Industrious Labs, a nonprofit advocating for heavy industry decarbonization, told me via email. But it’s difficult to know how much a company’s recent performance is attributable to the tariffs. “The impact of the steel tariffs are uneven and subject to other disruptions in the market,” Lewis said.
Industrious Labs aluminum lead Annie Sartor told me that Trump’s first term tariffs on aluminum failed to revitalize the industry, which she said “saw a continued downturn.” So while the latest tariffs are more robust, Sartor is hesitant to to think that “this will be a real game changer.” As she explained, “The biggest challenge that the industry faces is access to electricity, and specifically renewable electricity.” While the tariffs won’t directly address that, Sartor said that an optimistic analysis would suggest that with their extra revenue, companies that rely on electrification to clean up their operations “could use those additional funds to help them access the renewable energy that they want.”
At least for now, many of the leading companies have expressed strong support for Trump’s trade agenda. Century Aluminum’s CEO Jesse Gary said the tariffs “will help drive the resurgence of domestic aluminum production,” while Cleveland Cliff’s CEO Lourenco Goncalves stated they would “penalize the foreign competitors who have been playing by a different set of rules.” And while Leon Topalian, CEO of Nucor, acknowledged that the tariffs will increase the price of the raw materials for steel, such as iron ore, he told investors that he thinks this will be outweighed by “the overall macroeconomic trends in the industry, a healthy, vibrant steel industry.”
Aluminum giant Alcoa, which has also expressed interest in producing green aluminum, is an outlier among industry leaders in its opposition to tariffs. The company’s CEO, Bill Oplinger, told the crowd at a metals and mining conference in February that the disruption caused by the tariffs could eliminate 100,000 jobs in the domestic aluminum industry. The company operates two smelters in Canada that will be subject to tariffs, while it’s closed down many older smelters in the U.S. that it’s in no rush to reopen. “It’s hard to make a restart decision based on tariffs that could change,” Oplinger said during an analyst call, the Wall Street Journal reported. “We just don’t know whether they will stick.”
Startups focused narrowly on green metals production, however, have generally been more circumspect in their responses. “At this point, we’re trying to just stay steady through all of it — not reacting to the day-to-day,” Adam Rauwerdink, senior vice president at the green steel startup Boston Metal, told me. His company uses renewable power to electrolyze iron ore at high temperatures to create molten iron, the feedstock for steel.
Boston Metal has yet to build its first demonstration plant, and while Rauwerdink told me the tariffs could provide some incentive to site the facility in the states, the increase in domestic materials demand that tariffs will presumably bring is by no means enough to guarantee a U.S.-based facility will be worth it. “Here in the U.S. right now, the challenge is just the grid not being sufficient,” he said.
With electricity demand on the rise, green metals companies are now competing for renewable resources with tech giants that are trying to scoop up as much clean energy as possible to power their artificial intelligence-focused data centers. “Innovations like that, which change the landscape on the grid, can definitely impact some of these other solutions that are going to be competing for electrons and are probably less profitable than an AI data center,” Rauwerdink told me.
Electra, a startup that’s also using electrolysis to decarbonize the ironmaking process, recently landed a $186 million Series B funding round to build its demonstration plant in Colorado. But the tariffs aren’t enough for them to commit to the U.S. market, either. As the company’s CEO, Sandeep Nijhawan, told me, building a facility in an area with easy access to renewables is of paramount importance to them too.
Adding to all of this tariff-related uncertainty is the fact that many of these demonstration plants or first commercial facilities, including Brimstone’s, aren’t even scheduled to come online until the latter half of Trump’s term, if not the next decade. “We don’t know what the policy of the United States will be at that time,” Finke told me. The plan is for the company’s first commercial demonstration plant to be operational in 2030. “Maybe the next president will extend those tariffs, or maybe they will cut them back,” Finke said. After all, Biden mostly kept Trump’s first term tariffs on steel and aluminum in place — although prior to this February, there were numerous country-specific exemptions in place.
At the end of the day, tariffs are only one of numerous policy unknowns plaguing these green producers. Another major one is the status of the funding many of them were granted from the Department of Energy but have yet to see. In Brimstone’s case, that’s a $189 million award from the Office of Clean Energy Demonstrations to build its first plant. While Finke told me the company has started spending that money scoping out potential sites, it hasn’t yet been reimbursed. I asked him if that was concerning. “It’s a good question,” he told me. “At this time, it’s too early to say that.”
Similarly, Century Aluminum and Cleveland Cliffs both have $500 million awards from OCED to produce green aluminum and green steel, respectively. While I reached out to both companies for comment on the tariffs and the status of their funding, neither got back to me. Boston Metal also has a $50 million DOE grant for a facility that would produce chromium, a critical material for many advanced energy technologies. That money is, of course, now mired in “limbo and uncertainty,” Rauwerdink told me.
Green aluminum manufacturers large and small also stand to benefit from the Inflation Reduction Act’s advanced manufacturing production tax credit, which incentivizes the domestic production of critical minerals, as well as certain types of clean energy components. This credit — along with so many others — may or may not be slashed as Republicans look to cut funding for a variety of IRA-related initiatives in the budget reconciliation process.
While Finke told me — as so many other companies did — that Brimstone does not rely on tariffs, tax credits, or the company’s DOE grant for its survival, it sure would be nice to have just a little certainty for once. “What we’d really like is to know what number to put in our financial model,” he told me.
Wouldn’t we all.

“We had enough assurance that the president was going to deal with them.”
A member of the House Freedom Caucus said Wednesday that he voted to advance President Trump’s “big, beautiful bill” after receiving assurances that Trump would “deal” with the Inflation Reduction Act’s clean energy tax credits – raising the specter that Trump could try to go further than the megabill to stop usage of the credits.
Representative Ralph Norman, a Republican of North Carolina, said that while IRA tax credits were once a sticking point for him, after meeting with Trump “we had enough assurance that the president was going to deal with them in his own way,” he told Eric Garcia, the Washington bureau chief of The Independent. Norman specifically cited tax credits for wind and solar energy projects, which the Senate version would phase out more slowly than House Republicans had wanted.
It’s not entirely clear what the president could do to unilaterally “deal with” tax credits already codified into law. Norman declined to answer direct questions from reporters about whether GOP holdouts like himself were seeking an executive order on the matter. But another Republican holdout on the bill, Representative Chip Roy of Texas, told reporters Wednesday that his vote was also conditional on blocking IRA “subsidies.”
“If the subsidies will flow, we’re not gonna be able to get there. If the subsidies are not gonna flow, then there might be a path," he said, according to Jake Sherman of Punchbowl News.
As of publication, Roy has still not voted on the rule that would allow the bill to proceed to the floor — one of only eight Republicans yet to formally weigh in. House Speaker Mike Johnson says he’ll, “keep the vote open for as long as it takes,” as President Trump aims to sign the giant tax package by the July 4th holiday. Norman voted to let the bill proceed to debate, and will reportedly now vote yes on it too.
Earlier Wednesday, Norman said he was “getting a handle on” whether his various misgivings could be handled by Trump via executive orders or through promises of future legislation. According to CNN, the congressman later said, “We got clarification on what’s going to be enforced. We got clarification on how the IRAs were going to be dealt with. We got clarification on the tax cuts — and still we’ll be meeting tomorrow on the specifics of it.”
Neither Norman nor Roy’s press offices responded to a request for comment.
The foreign entities of concern rules in the One Big Beautiful Bill would place gigantic new burdens on developers.
Trump campaigned on cutting red tape for energy development. At the start of his second term, he signed an executive order titled, “Unleashing Prosperity Through Deregulation,” promising to kill 10 regulations for each new one he enacted.
The order deems federal regulations an “ever-expanding morass” that “imposes massive costs on the lives of millions of Americans, creates a substantial restraint on our economic growth and ability to build and innovate, and hampers our global competitiveness.” It goes on to say that these regulations “are often difficult for the average person or business to understand,” that they are so complicated that they ultimately increase the cost of compliance, as well as the risks of non-compliance.
Reading this now, the passage echoes the comments I’ve heard from industry groups and tax law experts describing the incredibly complex foreign entities of concern rules that Congress — with the full-throated backing of the Trump administration — is about to impose on clean energy projects and manufacturers. Under the One Big Beautiful Bill Act, wind and solar, as well as utility-scale energy storage, geothermal, nuclear, and all kinds of manufacturing projects will have to abide by restrictions on their Chinese material inputs and contractual or financial ties with Chinese entities in order to qualify for tax credits.
“Foreign entity of concern” is a U.S. government term referring to entities that are “owned by, controlled by, or subject to the jurisdiction or direction of” any of four countries — Russia, Iran, North Korea, and most importantly for clean energy technology, China.
Trump’s tax bill requires companies to meet increasingly strict limits on the amount of material from China they use in their projects and products. A battery factory starting production next year, for example, would have to ensure that 60% of the value of the materials that make up its products have no connection to China. By 2030, the threshold would rise to 85%. The bill lays out similar benchmarks and timelines for clean electricity projects, as well as other kinds of manufacturing.
But how companies should calculate these percentages is not self-evident. The bill also forbids companies from collecting the tax credits if they have business relationships with “specified foreign entities” or “foreign-influenced entities,” terms with complicated definitions that will likely require guidance from the Treasury for companies to be sure they pass the test.
Regulatory uncertainty could stifle development until further guidance is released, but how long that takes will depend on if and when the Trump administration prioritizes getting it done. The One Big Beautiful Bill Act contains a lot of other new tax-related provisions that were central to the Trump campaign, including a tax exemption for tips, which are likely much higher on the department’s to-do list.
Tax credit implementation was a top priority for the Biden administration, and even with much higher staffing levels than the department currently has, it took the Treasury 18 months to publish initial guidance on foreign entities of concern rules for the Inflation Reduction Act’s electric vehicle tax credit. “These things are so unbelievably complicated,” Rachel McCleery, a former senior advisor at the Treasury under Biden, told me.
McCleery questioned whether larger, publicly-owned companies would be able to proceed with major investments in things like battery manufacturing plants until that guidance is out. She gave the example of a company planning to pump out 100,000 batteries per year and claim the per-kilowatt-hour advanced manufacturing tax credit. “That’s going to look like a pretty big number in claims, so you have to be able to confidently and assuredly tell your shareholder, Yep, we’re good, we qualify, and that requires a certification” by a tax counsel, she said. To McCleery, there’s an open question as to whether any tax counsel “would even provide a tax opinion for publicly-traded companies to claim credits of this size without guidance.”
John Cornwell, the director of policy at the Good Energy Collective, which conducts research and advocacy for nuclear power, echoed McCleery’s concerns. “Without very clear guidelines from the Treasury and IRS, until those guidelines are in place, that is going to restrict financing and investment,” Cornwell told me.
Understanding what the law requires will be the first challenge. But following it will involve tracking down supply chain data that may not exist, finding alternative suppliers that may not be able to fill the demand, and establishing extensive documentation of the origins of components sourced through webs of suppliers, sub-suppliers, and materials processors.
The Good Energy Collective put out an issue brief this week describing the myriad hurdles nuclear developers will face in trying to adhere to the tax credit rules. Nuclear plants contain thousands of components, and documenting the origin of everything from “steam generators to smaller items like specialized fasteners, gaskets, and electronic components will introduce substantial and costly administrative burdens,” it says. Additionally the critical minerals used in nuclear projects “often pass through multiple processing stages across different countries before final assembly,” and there are no established industry standards for supply chain documentation.
Beyond the documentation headache, even just finding the materials could be an issue. China dominates the market for specialized nuclear-grade materials manufacturing and precision component fabrication, the report says, and alternative suppliers are likely to charge premiums. Establishing new supply chains will take years, but Trump’s bill will begin enforcing the sourcing rules in 2026. The rules will prove even more difficult for companies trying to build first-of-a-kind advanced nuclear projects, as those rely on more highly specialized supply chains dominated by China.
These challenges may be surmountable, but that will depend, again, on what the Treasury decides, and when. The Department’s guidance could limit the types of components companies have to account for and simplify the documentation process, or it could not. But while companies wait for certainty, they may also be racking up interest. “The longer there are delays, that can have a substantial risk of project success,” Cornwell said.
And companies don’t have forever. Each of the credits comes with a phase-out schedule. Wind manufacturers can only claim the credits until 2028. Other manufacturers have until 2030. Credits for clean power projects will start to phase down in 2034. “Given the fact that a lot of these credits start lapsing in the next few years, there’s a very good chance that, because guidance has not yet come out, you’re actually looking at a much smaller time frame than than what is listed in the bill,” Skip Estes, the government affairs director for Securing America’s Energy Future, or SAFE, told me.
Another issue SAFE has raised is that the way these rules are set up, the foreign sourcing requirements will get more expensive and difficult to comply with as the value of the tax credits goes down. “Our concern is that that’s going to encourage companies to forego the credit altogether and just continue buying from the lowest common denominator, which is typically a Chinese state-owned or -influenced monopoly,” Estes said.
McCleery had another prediction — the regulations will be so burdensome that companies will simply set up shop elsewhere. “I think every industry will certainly be rethinking their future U.S. investments, right? They’ll go overseas, they’ll go to Canada, which dumped a ton of carrots and sticks into industry after we passed the IRA,” she said.
“The irony is that Republicans have historically been the party of deregulation, creating business friendly environments. This is completely opposite, right?”

Current conditions: The northwestern U.S. faces “above average significant wildfire potential” for July • A month’s worth of rain fell over just 12 hours in China’s Hubei province, forcing evacuations • The top floor of the Eiffel Tower is closed today due to extreme heat.
The Senate finally passed its version of Trump’s One Big Beautiful Bill Act Tuesday morning, sending the tax package back to the House in hopes of delivering it to Trump by the July 4 holiday. The excise tax on renewables that had been stuffed into the bill over the weekend was removed after Senator Lisa Murkowski of Alaska struck a deal with the Senate leadership designed to secure her vote. In her piece examining exactly what’s in the bill, Heatmap’s Emily Pontecorvo explains that even without the excise tax, the bill would “gum up the works for clean energy projects across the spectrum due to new phase-out schedules for tax credits and fast-approaching deadlines to meet complex foreign sourcing rules.” Debate on the legislation begins on the House floor today. House Speaker Mike Johnson has said he doesn’t like the legislation, and a handful of other Republicans have already signaled they won’t vote for it.
The Environmental Protection Agency this week sent the White House a proposal that is expected to severely weaken the federal government’s ability to rein in planet-warming pollution. Details of the proposal, titled “Greenhouse Gas Endangerment Finding and Motor Vehicle Reconsideration,” aren’t clear yet, but EPA Administrator Lee Zeldin has reportedly been urging the Trump administration to repeal the 2009 “endangerment finding,” which explicitly identified greenhouse gases as a public health threat and gave the EPA the authority to regulate them. Striking down that finding would “free EPA from the legal obligation to regulate climate pollution from most sources, including power plants, cars and trucks, and virtually any other source,” wrote Alex Guillén at Politico. The title of the proposal suggests it aims to roll back EPA tailpipe emissions standards, as well.

So long, MethaneSAT, we hardly knew ye. The Environmental Defense Fund said Tuesday that it had lost contact with its $88 million methane-detecting satellite, and that the spacecraft was “likely not recoverable.” The team is still trying to figure out exactly what happened. MethaneSAT launched into orbit last March and was collecting data about methane pollution from global fossil fuel infrastructure. “Thanks to MethaneSAT, we have gained critical insight about the distribution and volume of methane being released from oil and gas production areas,” EDF said. “We have also developed an unprecedented capability to interpret the measurements from space and translate them into volumes of methane released. This capacity will be valuable to other missions.“ The good news is that MethaneSAT was far from the only methane-tracking satellite in orbit.
Nvidia is backing a D.C.-based startup called Emerald AI that “enables AI data centers to flexibly adjust their power consumption from the electricity grid on demand.” Its goal is to make the grid more reliable while still meeting the growing energy demands of AI computing. The startup emerged from stealth this week with a $24.5 million seed round led by Radical Ventures and including funding from Nvidia. Emerald AI’s platform “acts as a smart mediator between the grid and a data center,” Nvidia explains. A field test of the software during a grid stress event in Phoenix, Arizona, demonstrated a 25% reduction in the energy consumption of AI workloads over three hours. “Renewable energy, which is intermittent and variable, is easier to add to a grid if that grid has lots of shock absorbers that can shift with changes in power supply,” said Ayse Coskun, Emerald AI’s chief scientist and a professor at Boston University. “Data centers can become some of those shock absorbers.”
In case you missed it: California Governor Gavin Newsom on Monday rolled back the state’s landmark Environmental Quality Act. The law, which had been in place since 1970, required environmental reviews for construction projects and had become a target for those looking to alleviate the state’s housing crisis. The change “means most urban developers will no longer have to study, predict, and mitigate the ways that new housing might affect local traffic, air pollution, flora and fauna, noise levels, groundwater quality, and objects of historic or archeological significance,” explained Cal Matters. On the other hand, it could also mean that much-needed housing projects get approved more quickly.
Tesla is expected to report its Q2 deliveries today, and analysts are projecting a year-over-year drop somewhere from 11% to 13%.
