The Biden administration is hoping they’ll be a starting gun for the industry. The industry may or may not be fully satisfied.
In one of the Biden administration’s final acts to advance decarbonization, and after more than two years of deliberation and heated debate, the Treasury Department issued the final requirements governing eligibility for the clean hydrogen tax credit on Friday.
At up to $3 per kilogram of clean hydrogen produced, this was the most generous subsidy in the 2022 Inflation Reduction Act, and it came with significant risks if the Treasury did not get the rules right. Hydrogen could be an important tool to help decarbonize the economy. But without adequate guardrails, the tax credit could turn it into a shovel that digs the U.S. deeper into a warming hole by paying out billions of dollars to projects that increase emissions rather than reducing them.
In the final guidelines, the Biden administration recognized the severity of this risk. It maintained key safeguards from the rules proposed in 2023, while also making a number of changes, exceptions, and other “flexibilities” — in the preferred parlance of the Treasury Department — that sacrifice rigorous emissions accounting in favor of making the program easier to administer and take advantage of.
For example, it kept a set of requirements for hydrogen made from water and electricity known as the “three pillars.” Broadly, they compel producers to match every hour of their operation with simultaneous clean energy generation, buy this energy from newly built sources, and ensure those sources are in the same general region as the hydrogen plant. Hydrogen production is extremely energy-intensive, and the pillars were designed to ensure that it doesn’t end up causing coal and natural gas plants to run more. But the final rules are less strict than the proposal. For example, the hourly matching requirement doesn’t apply until 2030, and existing nuclear plants count as new zero-emissions energy if they are considered to be at risk of retirement.
Finding a balance between limiting emissions and ensuring that the tax credit unlocks development of this entirely new industry was a monumental challenge. The Treasury Department received more than 30,000 comments on the proposed rule, compared to about 2,000 for the clean electricity tax credit, and just 89 for the electric vehicle tax credit. Senior administration officials told me this may have been the most complicated of all of the provisions in the IRA. In October, the department assured me that the rules would be finished by the end of the year.
Energy experts, environmental groups, and industry are still digesting the rule, and I’ll be looking out for future analyses of the department’s attempt at compromise. But initial reactions have been cautiously optimistic.
On the environmental side, Dan Esposito from the research nonprofit Energy Innovation told me his first impression was that the final rule was “a clear win for the climate” and illustrated “overwhelming, irrefutable evidence” in favor of the three pillars approach, though he did have concerns about a few specific elements that I’ll get to in a moment. Likewise, Conrad Schneider, the U.S. senior director at the Clean Air Task Force, told me that with the exception of a few caveats, “we want to give this final rule a thumbs up.”
Princeton University researcher Jesse Jenkins, a co-host of Heatmap’s Shift Key podcast and a vocal advocate for the three pillars approach, told me by email that, “Overall, Treasury’s final rules represent a reasonable compromise between competing priorities and will provide much-needed certainty and a solid foundation for the growth of a domestic clean hydrogen industry.”
On the industry side, the Fuel Cell and Hydrogen Energy Association put out a somewhat cryptic statement. CEO Frank Wolak applauded the administration for making “significant improvements” but warned that the rules were “still extremely complex” and contain several open-ended parts that will be subject to interpretation by the incoming Trump-Vance administration.
“This issuance of Final Rules closes a long chapter, and now the industry can look forward to conversations with the new Congress and new Administration regarding how federal tax and energy policy can most effectively advance the development of hydrogen in the U.S.,” Wolak said.
Constellation Energy, the country’s biggest supplier of nuclear power, was among the most vocal critics of the proposed rule and had threatened to sue the government if it did not create a pathway for hydrogen plants that are powered by existing nuclear plants to claim the credit. In response to the final rule, CEO and President Joe Dominguez said he was “pleased” that the Treasury changed course on this and that the final rule was “an important step in the right direction.”
The California governor’s office, which had criticized the proposed rule, was also swayed. “The final rules create the certainty needed for developers to invest in and build clean, renewable hydrogen production projects in states like California,” Dee Dee Myers, the director of the Governor’s Office of Business and Economic Development, said in a statement. The state has plans to build a $12.6 billion hub for producing and using clean hydrogen.
Part of the reason the Treasury needed to find a Goldilocks compromise that pleased as many stakeholders as possible was to protect the rule from future lawsuits and lobbying. But not everyone got what they wanted. For example, the energy developer NextEra, pushed the administration to get rid of the hourly matching provision, which though delayed remained essentially untouched. NextEra did not respond to a request for comment.
Companies that fall on the wrong side of the final rules may still decide to challenge them in court. The next Congress could also make revisions to the underlying tax code, or the incoming Trump administration could change the rules to perhaps make them more favorable to hydrogen made from fossil fuels. But all of this would take time — a rule change, for example, would trigger a whole new notice and comment process. Though the one thing I’ve heard over and over is that the industry wants certainty, which the final rule provides, it’s not yet clear whether that will outweigh any remaining gripes.
In the meantime, it's off to the races for the nascent clean hydrogen industry. Between having clarity on the tax credit, the Department of Energy’s $7 billion hydrogen hubs grant program, and additional federal grants to drive down the cost of clean hydrogen, companies now have numerous incentives to start building the hydrogen economy that has received much hype but has yet to prove its viability. The biggest question now is whether producers will find any buyers for their clean hydrogen.
Below is a more extensive accounting of where the Treasury landed in the final rules.

On “deliverability,” or the requirement to procure clean energy from the same region, the rules are largely unchanged, although they do allow for some flexibility on regional boundaries.
As I explained above, the Treasury Department also kept the hourly matching requirement, but delayed it by two years until 2030 to give the market more time to set up systems to achieve it — a change Schneider said was “really disappointing” due to the potential emissions consequences. Until then, companies only have to match their operations with clean energy on an annual basis, which is a common practice today. The new deadline is strict, and those that start operations before 2030 will not be grandfathered in — that is, they’ll have to switch to hourly matching once that extended clock runs out. In spite of that, the final rules also ensure that producers won’t be penalized if they are not able to procure clean energy for every single hour their plant operates, an update several groups applauded.
On the requirement to procure clean power from newly built sources, also known as “incrementality,” the department made much bigger changes. It kept an overarching definition that “incremental” generators are those built within three years of the hydrogen plant coming into service, but added three major exceptions:
1. If the hydrogen facility buys power from an existing nuclear plant that’s at risk of retirement.
2. If the hydrogen facility is in a state that has both a robust clean electricity standard and a broad, binding, greenhouse gas cap, such as a cap and trade system. Currently, only California and Washington pass this test.
3. If the hydrogen facility buys power from an existing natural gas or coal plant that has added new carbon capture and storage capacity within three years of the hydrogen project coming into service.
The hydrogen tax credit is so lucrative that environmental groups and energy analysts were concerned it would drive companies like Constellation to start selling all their nuclear power to hydrogen plants instead of to regular energy consumers, which could drive up prices and induce more fossil fuel emissions.
The final rules try to limit this possibility by only allowing existing reactors that are at risk of retirement to qualify. But the definition of “at risk of retirement” is loose. It includes “merchant” nuclear power plants — those that sell at least half their power on the wholesale electricity market rather than to regulated utilities — as well as plants that have just a single reactor, which the rules note have lower or more uncertain revenue and higher operational costs. Looking at the Nuclear Energy Institute’s list of plants, merchant plants make up roughly 40% of the total. All of Constellation Energy’s plants are merchant plants.
There are additional tests — the plant has to have had average annual gross receipts of less than 4.375 cents per kilowatt hour for at least two calendar years between 2017 and 2021. It also has to obtain a minimum 10-year power purchase agreement with the hydrogen company. Beyond that, the reactors that meet this definition are limited to selling no more than 200 megawatts to hydrogen companies, which is roughly 20% for the average reactor.
Esposito, who has closely analyzed the potential emissions consequences of using existing nuclear plants to power hydrogen production, was not convinced by the safeguards. “I don't love the power price look back,” he told me, “because that's not especially indicative of the future — particularly this high load growth future that we're quickly approaching with data centers and everything. It’s very possible power prices could go up from that, and then all of a sudden, the nuclear plants would have been fine without hydrogen.”
As for the 200 megawatt cap, Esposito said it was better than nothing, but he feels “it's kind of an implicit admission that it's not really, truly clean” to produce hydrogen with the energy from these nuclear plants.
Schneider, on the other hand, said the safeguards for nuclear-powered hydrogen projects were adequate. While a lot of plants are theoretically eligible, not all of their electricity will be eligible, he said.
The rules assert that in states that meet the two criteria of a clean electricity standard and a binding cap on emissions, “any increased electricity load is highly unlikely to cause induced grid emissions.”
But in a paper published in February, Energy Innovation explored the potential consequences of this exemption in California. It found that hydrogen projects could have ripple effects on the cap and trade market, pushing up the state’s carbon price and triggering the release of extra carbon emission allowances. “In other words, the California program is more of a ‘soft’ cap than a binding one — the emissions budget ‘expands or contracts in response to price bounds set by the legislature and [California Air Resources Board],’” the report says.
Esposito thinks the exemption is a risk, but that it requires further analysis and he’s not sounding the alarm just yet. He said it could come down to other factors, including how economical hydrogen production in California ends up being.
Producers are also eligible for the tax credit if they make hydrogen the conventional way, by “reforming” natural gas, but capture the emissions released in the process. For this pathway, the Treasury had to clarify several accounting questions.
First, there’s the question of how producers should account for methane leaked into the atmosphere upstream of the hydrogen plant, such as from wells and pipelines. The proposal had suggested using a national average of 0.9%. But researchers found this would wildly underestimate the true warming impact of hydrogen produced from natural gas. It could also underestimate emissions from natural gas producers that have taken steps to reduce methane leakage. “We branded that as one size fits none,” Schneider told me.
The final rules create a path for producers to use more accurate, project-specific methane emissions rates in the future once the Department of Energy updates a lifecycle emissions tool that companies have to use called the “GREET” model. The Environmental Protection Agency recently passed new methane emissions laws that will enable it to collect better data on leakage, which will help the DOE update the model.
Schneider said that’s a step in the right direction, though it will depend on how quickly the GREET model is updated. His bigger concern is if the Trump administration weakens or eliminates the EPA’s methane emissions regulations.
The Treasury also opened up the potential for companies to produce hydrogen from alternative, cleaner sources of methane, like gas captured from wastewater, animal manure, and coal mines. (The original rule included a pathway for using gas captured from landfills.) In reality, hydrogen plants taking this approach are unlikely to use gas directly from these sources, but rather procure certificates that say they have “booked” this cleaner gas and can “claim” the environmental benefits.
Leading up to the final rule, some climate advocates were concerned that this system would give a boost to methane-based hydrogen production over electricity-based production, as it's cheaper to buy renewable natural gas certificates than it is to split water molecules. Existing markets for these credits also often overestimate their benefits — for example, California’s low carbon fuel system gives biogas captured from dairy farms a negative carbon intensity score, even though these projects don’t literally remove carbon from the atmosphere.
The Treasury tried to improve its emissions estimates for each of these alternative methane sources to make them more accurate, but negative carbon intensity scores are still possible.
The department did make one significant change here, however. It specified that companies can’t just buy a little bit of cleaner methane and then average it with regular fossil-based methane — each must be considered separately for determining tax credit eligibility. Jenkins, of Princeton, told me that without this rule, huge amounts of hydrogen made from regular natural gas could qualify.
Producers also won’t be able to take this “book and claim” approach until markets adapt to the Treasury’s reporting requirements, which isn’t expected until at least 2027.

Whichever way you cut it, this has been an absolute banner year for nuclear deals in the U.S. It doesn’t much matter the metric — the amount of venture funding flowing to nuclear startups, the number of announcements regarding planned reactor restarts and upgrades, gigawatts of new construction added to the pipeline — it’s basically all peaking. Stock prices are up across all major publicly traded nuclear companies this year, in some cases by over 100%.
“This year is by far the biggest year in terms of nuclear deals that has occurred, probably, since the 70s,” Adam Stein, the director of nuclear innovation at The Breakthrough Institute, told me. “It’s spanning the gamut from bringing a 40-year-old reactor back to things that have not even been proven scientifically yet.”
To name just a few announcements from this year: planning for a 4.4-gigawatt nuclear power complex is now underway in Texas; South Carolina’s state-owned utility is seeking buyers to restart construction on two partially built AP1000 reactors; New York governor Kathy Hochul is looking to build a new reactor in upstate New York; The Tennessee Valley Authority submitted a construction permit for a small modular reactor; Google signed a power purchase agreement with Commonwealth Fusion Systems; and another fusion company, Helion Energy, raised a whopping $425 million round of venture capital. On top of all that there’s the Palisades nuclear power plant in Michigan, which is targeted to restart by year’s end, bringing 800 megawatts of new nuclear power online.
Heading into the second Trump term, there were plenty of indications that the administration would support this technology with increasingly bipartisan appeal. So it wasn’t exactly a surprise that while the One Big Beautiful Bill eviscerated tax credits for solar and wind, it preserved them for both existing and new nuclear facilities. Now that this support is assured, Stein expects the nuclear announcements to keep rolling in. “We might have seen more deals earlier this year if there wasn’t uncertainty about what was going to happen with tax credits. But now that that’s resolved, I expect to hear more later this year,” he told me.
How much of this is, I asked him, is due to data centers and their seemingly insatiable demand for clean, firm power? “Most of it,” he said simply. By way of example, he pointed out how data center load growth has changed the outlooks for two small modular reactor companies in particular. “NuScale has been trying to find their first project for a long time now, after they had to cancel their [Utah Associated Municipal Power Systems] project. Kairos didn’t have a clear buyer for its first-of-a-kind, even though it was building two test reactors,” Stein explained. “Then all of a sudden, they all had additional deals in the works because of data center demand.”
Last year, Kairos inked a 500-megawatt deal with Google to meet the hyperscaler’s growing data center needs, while this year, Texas A&M selected the company — along with three others — to build a reactor at the university’s research and development campus. And while NuScale infamously canceled its first project in 2023 due to rising costs, this year it received approval from the Nuclear Regulatory Commission for a new and improved reactor design. Now the company’s CEO, John Hopkins, told Reuters that NuScale is in talks to deploy its tech with five unnamed “tier one hyperscalers.” Its stock is up more than 150% on the year.
That’s a big turnaround for a company that, less than two years ago, was widely considered a cautionary tale — and it’s not the only one in the industry with this type of comeback story. Right before NuScale’s project failed, another nuclear company, X-energy, announced that it would no longer go public due to “challenging market conditions” and “peer company trading performance.” But while X-energy still has yet to IPO, it appears to be doing just fine. In February, the company announced the close of a $700 million Series C follow-on round, coming on the heels of Amazon’s strategic investment last year.
“I think every company has their stories about how things are changing,” Seth Grae, CEO of the advanced nuclear fuel company Lightbridge, told me. Things have moved a lot faster, Grae said, since Trump released a series of executive orders aimed at accelerating nuclear energy deployment. “Just since May, we’ve received this highly enriched uranium [from the Department of Energy], made these fuel samples, got them qualified already at Idaho National Lab. We expect they’ll be in the reactor this year. Grae told me. “Things didn’t used to happen that fast in nuclear.”
Trump’s plans to fast track nuclear development have also raised serious concerns, however, as critics worry that acceleration could lead to laxer safety standards The executive orders call for, among other things, cutting staff at the Nuclear Regulatory Commission, just as the industry enters a period of intense activity. In June, the President fired one of the agency’s commissioners, Christopher Hanson, without cause. Another commissioner, Annie Caputo, resigned in July.
But right now, the nuclear industry is mostly basking in optimism. Grae credits the government’s strong support for the surge in nuclear stocks — Lightbridge’s own stock price has jumped 180% this year, while another nuclear fuel company, Centrus Energy, is up even more. The small modular reactor company Oklo is up 285% for the year, on the heels of last year’s 12-gigawatt non-binding deal with the data center company Switch — one of the largest corporate clean power agreements to date.
Last year’s slew of deals involving Oklo, X-energy, and Kairos show that the sector’s momentum had been building well before Trump took office. By 2023, the writing was already on the wall in terms of data center load growth, as grid planners began to predict a sharp rise in electricity demand after over a decade of stagnation. But when I asked Erik Funkhauser of the Good Energy Collective whether the prior two years compared with this one, he concurred with Stein. “Nope,” he told me. “We’re seeing capital infusion at a really, really high pace, as high of a pace as the company’s suppliers can keep up with on projects.”
Still, the party may not go on forever. “I see a potential for a Valley of Death,” Stein told me, similar to what many startups go through when they’re trying to raise later-stage funding rounds.
“If things don’t start to actually move forward with real progress, either getting licenses or building prototypes on time, then all of that investment will be pulled back.” That’s what the U.S. saw during the last so-called “nuclear renaissance” in the late 2000s, he explained, when a rash of large reactors were proposed with only two actually reaching completion.
These were the notorious Vogtle reactors 3 and 4 in Georgia, which finally came online in 2023 and 2024 respectively, running billions over budget and years behind schedule. In order for this latest round of nuclear enthusiasm to avoid the same fate, Stein told me it’s critical that leading projects demonstrate enough early success to maintain developer confidence in the economic and technical viability of new — and old — nuclear technologies.
That being said, the sector will inevitably contract. “Back when we saw this last scale-up, there were three designs that were really competing for attention, and now there are 75. So we’re going to see a lot of failures,” Stein said. The question for venture investors, he told me, is “how many failures of startups that you didn’t invest in are you willing to tolerate before you start to think the whole segment has trouble?”
The second main way this could all fall to pieces, he told me, is if “somebody tries to move too fast,” and that recklessness leads to “either a bankruptcy or an accident or something like that that will send ripples or shock waves through the whole sector.”
Indeed, a metaphorical or literal meltdown in the sector could put a quick halt to this year’s frenzied momentum. But within the next few years, as these announced projects begin to line up their licenses and come online — or fall apart— we’ll soon see whether this latest nuclear revival is a true turning point or just another bubble.

An August 5 chart showing last month's record electricity demand peaks.EIA
The United States’ demand for electricity broke records twice last month. Air conditioners cranking on hot days, combined with surging demand from data centers, pushed the peak in the Lower 48 states to a high of 758,053 megawatts on July 28, between 6 p.m. and 7 p.m. EST, data from the U.S. Energy Information Administration’s Hourly Electric Grid Monitor shows. The following day, peak demand set another record, hitting 759,180 megawatts. That’s nearly 2% above the previous record set on July 15, 2024.
The EIA predicted demand to grow by more than 2% per year between 2025 and 2026. Forecasts are even higher in areas with large data centers and factories underway, such as Texas and northern Virginia. The milestone comes as the Trump administration cracks down on solar and wind energy, two of the fastest-growing and quicker-to-build sources of new generation. On Tuesday, The New York Times reported that the Environmental Protection Agency is moving to eliminate $7 billion in spending on grants for solar energy, though when Heatmap’s Emily Pontecorvo asked the agency, it said only that, “With the passage of the One Big Beautiful Bill, EPA is working to ensure Congressional intent is fully implemented in accordance with the law.”
Senator Brian Schatz, a Democrat from Hawaii, locked down enough votes on Tuesday to replace Illinois Senator Dick Durbin as the Democrats’ whip in the chamber. Durbin, who is retiring next year, has served in the Senate Democrats’ No. 2 position since 2005. In his endorsement on Tuesday, Senate Minority Leader Chuck Schumer of New York called Schatz “a close friend and one of my most valued allies.”
Schatz crusaded for the Inflation Reduction Act and told Heatmap he supported last year’s failed bipartisan permitting reform deal, even as progressive greens campaigned against its giveaways to fossil fuels. In a Shift Key podcast interview with my colleague Robinson Meyer and his co-host, Princeton professor Jesse Jenkins, in February, Schatz pitched a big tent for climate action. “We all have to hang together. It’s the American Clean Power Association. It’s the energy company that does both clean and fossil energy. It’s the transmission and distribution companies. It’s the manufacturers. It’s labor. It’s Wall Street. It’s K Street. Everyone has to hang together and say, not only is this good for business, but there’s something that is foundationally worse for business than any individual policy decision.”

The Trump administration may be clawing back funding for cleaning up heavy industry, but Big Tech is still inking deals. On Monday, Amazon agreed to buy low-carbon cement from the startup Brimstone. Then on Tuesday, the data center developer STACK Infrastructure announced the completion of “a pilot pour” of green cement from rival startup Sublime. The moves highlight the growing demand for cleaner industrial materials amid increased scrutiny of the energy and pollution linked to server farms.
America’s uranium enrichment went out of business in the early 2000s after the Clinton-era megatons-to-megawatts program essentially ceded the industry to cheap Russian imports made from disassembled atomic weapons. Since banning imports from Russia last year, the U.S. has been ramping up funding for nuclear fuel again, especially as the industry looks to build new types of reactors that rely on fuel other than the low-enriched uranium that virtually all the country’s operating 94 commercial reactors use. On Monday, the Department of Energy announced its first pilot project for advanced nuclear fuels, giving the startup Standard Nuclear the first federal deal. On Tuesday, the agency signed a $1.5 billion deal to restore the so-called Atomic City on the 100-acre parcel of federal land at the former Paducah Gaseous Diffusion Plan in Kentucky.
The Trump administration gave permission to the National Weather Service to hire up to 450 meteorologists, hydrologists, and radar technicians after sweeping cuts from the Department of Government Efficiency, CNN’s Andrew Freedman reported. The agency, which was partly blamed for its warnings going unheeded ahead of the deadly Texas floods last month, also received an exemption from the federal hiring freeze.
The move came the same day as a federal judge blocked the administration from diverting billions of dollars in Federal Emergency Management Agency funding for disaster resilience and flood mitigation. The injunction warned FEMA against spending the money on anything else.
Beyond Meat is finally getting beyond meat. The company plans to shed the flesh reference in its name this week as it launches its new Beyond Ground product that promises more protein than ground beef. “With this launch,” Fast Company’s Clint Rainey reported, “Beyond Meat is becoming merely Beyond and turning its focus away from only mimicking animal proteins to letting plant-based proteins speak for themselves. The radical move is cultural, agricultural, and financial.”
Rob and Jesse talk through the proposed overturning of the EPA’s “endangerment finding” on greenhouse gases with Harvard Law School’s Jody Freeman.
The Trump administration has formally declared that carbon dioxide and other greenhouse gases are not dangerous pollutants. If the president gets his way, then the Environmental Protection Agency may soon surrender any ability to regulate heat-trapping pollution from cars and trucks, power plants, and factories — in ways that a future Democratic president potentially could not reverse.
On this week’s episode of Shift Key, we discuss whether Trump’s EPA gambit will work, the arguments that the administration is using, and what it could mean for the future of U.S. climate and energy policy. We’re joined by Jody Freeman, the Archibald Cox Professor of Law at Harvard and the director of Harvard’s environmental and energy law program. She was an architect of the Obama administration’s landmark deal with automakers to accept carbon dioxide regulations.
Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.

Here is an excerpt from our conversation:
Robinson Meyer: I just want to make a related question, which is, you can actually say some of the sentences in the DOE report — you can believe tornadoes don’t show any influence from climate change and still believe heatwaves do, and still believe extreme rainfall events do. In fact, you could believe the cost of heat waves getting worse could justify the entire regulatory edifice.
Jody Freeman: What I love about you, Rob, right now, is you’re kind of incensed about little points that might individually sort of be right, maybe each one separately, but none of it adds up to even a chink in the armor. Right? And what’ll have to happen is the scientific community writ large, en masse, is going to have to come back and say, even if one or two or three of these sentences could possibly, plausibly be actually accurate, it does nothing to change the overwhelming —
Jesse Jenkins: It doesn’t matter.
Freeman: Right. What I think is happening is we’re all getting poked and distracted and tweaked into outrage over science, when in fact, the first argument they’re making is the one where they could actually attract some judges and justices to say, Oh wait, maybe you have a little more discretion here to set a threshold level. You know, Maybe it matters that you’re saying nothing we do here in the U.S. will make a difference in the end to global warming, and maybe that is a reason you don’t want to regulate. Hmm, maybe we’ll accept that reason. And that’s what we need, I think, to be more concerned about.
Jenkins: You’re saying, don’t get distracted by the fight over the climate science. That fight is very clear. It’s this legal argument that this isn’t an air pollutant because it’s not a local air pollutant, it mixes globally with all the other CO2, and we can’t, you know, each class of cars is a tiny contributor to that, and so we shouldn’t worry about it —
Freeman: And much of this is a replay, or a rehash of arguments that the George W. Bush administration lost in Massachusetts vs. EPA. So a lot of this is like, let’s take another run at the Supreme Court.
