Widespread federal layoffs bring even more uncertainty to the DAC hubs program.

Grant Faber suspected his short tenure as the program manager for the Department of Energy’s direct air capture hubs initiative was up when he saw an article circulating that the department was set to terminate up to 2,000 employees — generally those who were new to their jobs. When he hadn’t received any news by the end of the day on Thursday, February 13, he told me he felt a sense of “anticipatory survivor’s guilt.” But it wouldn’t last long.
“I woke up Friday morning and I was locked out of all my systems, and I had to get my termination letter emailed to my personal email address,” Faber told me. “It more or less just said it’s in the public interest to do away with your job.”
President Trump's campaign to fire federal workers has hollowed out the DOE's nascent Carbon Dioxide Removal team, which sits within the Office of Fossil Energy and Carbon Management. When Trump first took office there were five employees on the CDR team, which helps to oversee implementation of the $3.5 billion Regional Direct Air Capture Hubs program, Faber told me. Now, he said, there’s only one left.
Trump’s layoffs targeted probationary employees, i.e. those who had been hired, promoted, demoted, or reassigned within the past one to two years, who enjoy fewer job protections than those with longer tenures. Faber had been at his job for 11 months. His former boss, Rory Jacobson, was also terminated a few weeks ago, as he’d recently been promoted to a new role as director of carbon removal at the DOE. “To my knowledge, this was not about terminating people that were doing DAC work, or climate work, or even CDR work,” Jacobson told me. “This was just a gross termination of federal employees, career federal employees across the federal government that were on probation.”
But the cumulative effect of these layoffs certainly increases the air of uncertainty around the DAC hubs program, which thus far include two large-scale projects — the South Texas DAC Hub and Louisiana’s Project Cypress — as well as 19 smaller hubs in earlier stages of feasibility and design development.
The various hubs’ commercial partners, which include universities, oil giants, and DAC startups themselves, were already mired in the limbo created by Trump’s Day One executive order, which froze funding from the Inflation Reduction Act and the Bipartisan Infrastructure Law. That order also led to an effective communications embargo, which prohibits the DOE from discussing or taking action on things such as contract negotiations or personnel decisions with its external partners. These recent terminations just add to the confusion.
“We’ve had no communications with DOE for three to four weeks now,” the lead of one DAC hub in the feasibility study stage told me. “So we’re kind of just waiting to see what they tell us to do.”
In the meantime, awardees are frustrated and unsure where to turn, Jacobson told me. “Should they reach out to their congressperson and try to get them to advocate on their behalf? Do they send a letter to the White House? What is the next step to try and make things move for their projects?” These doubts pose a big problem for startups with novel technologies trying to build out large infrastructure projects, as they generally have smaller margins, less patient investors, and thus less room for error than industrial stalwarts with proven strategies. “Especially for these first-of-a-kinds, they are working on pretty dire timelines for project finance,” Jacobson said.
The DAC hubs were already off to a slow start, according to Jacobson, who told me that the $1.2 billion from the initial funding opportunity issued at the end of 2022 took much longer to get out the door than anyone hoped for. Project Cypress didn’t see any of its initial $50 million award until March of last year, and the South Texas hub had to wait until September for the same funding. Jacobson chalked up the delays to the fact that the awardees are generally relatively early-stage startups that have yet to build significant infrastructure projects, and that the DOE is unfamiliar with negotiating such large-scale proposals.
Thankfully the DOE’s small CDR division isn’t the only government entity interfacing with the DAC hubs. The Office of Clean Energy Demonstrations is overseeing the buildout of the larger South Texas and Project Cypress hubs. And the National Energy Technology Laboratory is overseeing the implementation of the smaller DAC hubs, which are in the feasibility study and design planning stages. They’ve received a combined total of $121 million so far, though some are still negotiating the size of their awards.
OCED and NETL have also been impacted by the government-wide staffing cuts, however, potentially affecting their ability to pick up the slack from the decimated CDR team, which helped to provide top-level oversight and expertise. As Jacobson told me, his job was to “make a theory of change” that united the DOE’s various carbon removal initiatives, aligning them with the administration’s overall energy strategy, whatever it was. Absent this broader vision and explicit strategic direction, coordination among the various government agencies and implementation partners could suffer.
Day-to-day organizational details also stand to falter, Faber told me. In his role, he primarily provided oversight for the 19 smaller, earlier stage DAC hubs. “A lot of times, progress can come down to literally just things like getting signatures, getting approvals, communicating things to leadership back and forth,” he said. “If you don’t have a team in place coordinating those things at headquarters, everything’s just going to be more difficult.”
All that’s to say that further hold-ups could hit the hubs hard, especially the two large projects, which could eventually receive federal funding of up to $500 million to $600 million, provided the hubs can match that with funding from other sources. “If the DOE tries to back out or withholds funding and there’s uncertainty, then yes, it could severely delay or even kill some of those projects, or just result in massive reductions in their scope,” Faber told me. Perhaps other investors, such as climate tech VCs, would be willing to step in if this were to happen, he added.
Faber noted that one proof point that could give investors and other industry leaders confidence in this tech is the forthcoming large-scale DAC facility called Stratos from developer 1PointFive, a subsidiary of Occidental Petroleum, which is designed to remove up to 500,000 metric tons of CO2 annually and set to come online later this year. While Stratos is not a part of the hubs program, Occidental is using the same technology for its South Texas hub — tech that the oil giant brought in-house when it acquired DAC startup Carbon Engineering in 2023. And Heirloom, a DAC company that’s helping to lead Project Cypress, also recently raised a huge $150 million Series B round, showing continued investor confidence in this technology.
The DAC hubs program also still has billions of dollars yet to be awarded. A few months ago, the DOE announced a new $1.8 billion funding opportunity for mid- and large-scale DAC projects. Interested parties have already submitted their required concept papers and pre-applications, with full applications due at the end of July. But the current chaos puts applicants in a tricky spot, as the new administration’s commitment to the program overall is now somewhat of a question mark.
That being said, Jacobson told me there’s no indication that either Trump or Secretary of Energy Chris Wright is necessarily opposed to DAC, or carbon dioxide removal overall. “I still don’t think that we’ve seen a clear signal that this administration is not excited about CDR,” Jacobson said. “I have not heard Secretary Wright say — or other leadership at DOE say — that we are not still very enthusiastic about DAC hubs.”
DAC buildout also has an array of bipartisan benefits, both Jacobson and Faber noted, and hasn’t been a target of right-wing ire in the way that electric vehicles and offshore wind have. On the contrary, Republicans (and oil and gas companies) often argue for it as a way to continue fossil fuel production in a world that’s moving towards lower-emissions sources of energy. Not to mention the fact that these DAC facilities are mainly being built in red states, thus adding jobs and GDP in these regions.
“I thought these kinds of projects would get to keep going,” the DAC hub leader, whose project has had elements halted, told me. “They’re creating jobs, they’re investing in technology. I think they could be well aligned with unleashing America’s energy dominance.”
But these days, few Biden-era initiatives are safe. As Faber told me, if the Trump administration chooses to take a hard line stance against “any and all government funding and regulation, and anything that even has a tinge of being associated with climate,” then DAC is going to have a target on its back, even if some congressional Republicans have previously expressed support for it.
The budget reconciliation process will give us more insight into the specific IRA and BIL funding provisions Trump and other Republicans are looking to axe. That same process will also determine the fate of tax credits such as 45Q, which encourages carbon capture and sequestration. In the near term, Democrats are pushing to get language into the government funding bill (which is separate from the reconciliation bill and must pass in some form by mid-March) that would require Trump to deliver congressionally appropriated money. If that happens, funds would start flowing to the DAC hubs — but don’t bet on it. Republicans are adamant that they won’t stand for such limitations on presidential authority.
DAC grantees, government employees, and implementation partners alike will have to do the wait-and-see thing for a while longer. “I do believe that when we get out of this fog of the first 100 days of the new administration, when they’re just trying to move fast and break things and get big headlines and try to make it seem like they’re keeping campaign promises, maybe things will slow down,” Faber told me. “Maybe they’ll get distracted or just move on to a new issue other than dismantling the federal government.”

Environmental groups are lining up against an influx of new PFAS designed to cool AI infrastructure.
This spring, the chemicals company Chemours asked the U.S. government for permission to begin manufacturing 3-Hexene, 1,1,1,2,2,5,5,6,6,6-decafluoro-, (3E)- (CAS RN 1256353-26-0). Because that’s a mouthful, the company also gave the new compound an easier-to-say name: Opteon 2P50.
Under normal circumstances, the filing for Opteon 2P50 would not have been particularly remarkable. As it stands, the compound is one of several hundred chemicals currently under review by the Environmental Protection Agency, pursuant to Section 5 of the Toxic Substances Control Act — the statute that requires companies to seek government approval before they start pumping out new goos, gels, gases, and solvents for commercial use. But when filing its premanufacture notice this spring, Chemours flagged Opteon 2P50 for priority review, describing the “critical societal need” the chemical “directly addresses” — that is, the build-out of data centers.
A surge in demand for coolants, water treatments, specialized fire suppressants, and coatings for semiconductors, among other chemicals, has paralleled the data center boom. One market research firm projects that the market for immersion-cooling fluids alone will grow from just shy of $4.9 billion to $11.1 billion by 2030. The industry has seized on the opportunity, with the American Chemistry Council running sponsored content in Beltway publications like Politico and Axios last year pushing for regulatory easements. “AI and other breakthroughs depend on chemistry,” one such headline reads.
Then last summer, President Trump issued an executive order to streamline the federal permitting and regulatory processes around artificial intelligence. EPA Administrator Lee Zeldin followed that move with an announcement that the agency would henceforth prioritize TSCA reviews for any data center-related chemicals and compounds, bypassing what is often a years-long bottleneck. In the eight months since, I’ve counted four new filings for chemicals with purported data center cooling uses, including a rival coolant to Opteon 2P50 from Schimmer & Schwarz.
But Opteon 2P50 stands out for a few reasons. The biggest is that the compound is a polyfluoroalkyl substance, which, along with perfluoroalkyl substances, are referred to as PFAS, or colloquially as “forever chemicals.” Opteon 2P50’s fast-track request has alarmed environmental, public health, and watchdog groups, who fear that the Trump administration’s regulatory shortcut has created a fast lane for approving new PFAS, which can be nearly impossible to remove from the environment once contamination occurs.
So far, two data center-related PFAS are under review by the EPA, Maria Doa, the chemicals policy senior director at the Environmental Defense Fund, told me: a heat transfer fluid with an “almost completely redacted” filing, and Opteon 2P50. While the latter filing is also heavily redacted, it left enough of a paper trail of lab work and toxicology studies that Earthjustice felt it had the grounds to build a credible opposition. “There was a lot of information for us to comment on and make an opinion on the chemical,” Adriana Antezana, a staff scientist at Earthjustice, told me. “It was also one of the few chemicals so far that have been submitted for the EPA to do a priority review under the executive order to prioritize data center infrastructure. That’s why we flagged it.”
It’s fairly common for premanufacture notices, or PMNs, to include heavy redactions as companies argue they need to shield confidential business information; about two-thirds of TSCA filings from 1979 to 2009 did so in the name of protecting trade secrets, according to a review by the Environmental Working Group, a nonpartisan public health and accountability organization. Still, an Earthjustice-fronted coalition of 17 environmental groups has formally asked the EPA to deny the premanufacture notice for Opteon 2P50 because they say it presents “unreasonable risk” to human health and the environment as a PFAS. They also contend that the full information on the risks to people who’ve been exposed to Opteon 2P50 is “unlawfully” redacted from the filing.
“It seems like chemical companies that create PFAS are hopping on the opportunity to create them for electrical industries,” Antezana said. “Obviously this administration is very supportive of semiconductor manufacturing and data centers, and it seems like, unfortunately, there is an opportunity there for a lot of them to get their chemicals approved and used widely.”
Also at play: The company 3M ceased manufacturing PFAS at the end of last year, leaving a vacuum that Chemours appears eager to fill with Opteon 2P50. The new liquid could replace 3M’s Novec immersion-cooling fluid, the previous industry standard, because it also doesn’t conduct electricity. The appeal of such a chemical is obvious: Many data centers currently use water-intensive evaporative cooling or chilling systems to keep their electronics from overheating. (This is why some opponents describe AI as “thirsty.”) Opteon 2P50, on the other hand, facilitates a completely closed-loop system. Because it doesn’t conduct electricity, electronic equipment can be submerged directly into the fluid, which boils off the heat. The vapors cool and condense back into a liquid — the referent in “two-phase immersion cooling” — and recirculate into the tanks.
Chemours has said that Opteon 2P50 can lead to a 90% reduction in cooling energy, a 60% reduction in a data center’s physical footprint, and “nearly eliminate water use,” all with minimal leakage into the environment — the estimated upper-bound emission rate is 2% per year, a company spokesperson told me. (Chemours declined to make a spokesperson available for an interview for this story and provided a statement about its filing via email. The EPA did not respond to a request for comment.)
Chemours has also insisted that Opteon 2P50 is not, in fact, a PFAS. On its face, that is a dubious argument. Per the internationally used structural definition of a PFAS, it's right in the compound’s long formal name, with the initial string of 10 numbers describing the location of 10 fluorine atoms bonded to carbon — the strongest common single bond in organic chemistry and the reason “forever” chemicals are so difficult to break down and remove once they enter the environment. (It’s also why they make great water-resistant coatings.)
But if a PFAS designation is intended to characterize the persistence of a compound — a narrower definition used by the EPA — then Opteon 2P50 doesn’t fit the bill. After a lifespan of only about 70 days in the atmosphere, it reacts and breaks apart into perfluorinated aldehyde, which in turn breaks down into two ultra-short-chain PFAS: perfluoropropanoic acid (PFPrA) and trifluoroacetic acid (TFA).
It might seem like splitting hairs — if Opteon 2P50 eventually breaks down into PFAS, shouldn’t that be all that matters? — but the company’s aversion to the label is understandable. Concern around PFAS has ballooned in recent years as awareness of the difficulty (and in some cases, near impossibility) of removing such compounds from drinking water has increased. The known and suspected health effects of some PFAS, such as PFOA, can also be alarming, including cancers, fertility issues, and pregnancy complications. The issue has created a rift in Trumpworld, dividing the Make America Healthy Again contingent from regulatory reform advocates and industry lobbyists.
While a minority of data centers across the country use closed-loop cooling systems at this point, and of those an even smaller subset use immersion cooling that requires a specialized dielectric fluid like a PFAS, new facilities are already facing public opinion headwinds that a PFAS association could compound. (In a statement, the American Chemistry Council told me: “Not all PFAS are the same. Individual chemistries have differing properties, uses, and environmental and health profiles, and should be evaluated based on their specific characteristics and the best available science rather than treated as a single class.”)
While Chemours argues that leakage isn’t an issue with Opteon 2P50, the fact that it shared an estimated emission rate with me at all acknowledges the realistic possibility that some will reach the outside world. That may be during manufacturing — Chemours said in its filing that it will make Opteon 2P50 outside the United States and import it to its headquarters, but if the PMN is approved, it will also have legal grounds to produce it stateside — or during its disposal, after an estimated 20 years of use in a data center, as confirmed to me by a company spokesperson. But there are few clues to what that end-of-life disposal process would look like. Antezana of Earthjustice told me that in Chemours’ filing, there is “virtually no acknowledgment of disposal” at all. Chemours’ marketing also suggests it is interested in exploring the use of Opteon 2P50 outside data centers, including in electric vehicle batteries, where leaks would presumably be more difficult to contain.
“The rule of thumb is that refrigerants leak,” Lenny Siegel, the director of Chips Communities United, a CHIPS Act watchdog group that also opposes the approval of Opteon 2P50, explained to me. “They can leak when they’re being made; they can leak when they’re being stored; they can leak when they’re being transported; they can leak when they’re being installed in tanks or removed from tanks. My refrigerator might last 20 years, but the electronics in a data center will probably be obsolete in a few years, and there’s been no discussion of how they’re going to make sure that there’s no release [of Opteon 2P50].”
Siegel mentioned his refrigerator because Opteon 2P50 is also a hydrofluoroolefin, or HFO — a class of compounds that break down in the atmosphere in a matter of weeks and are used as alternatives to older CFCs and HFCs, refrigerants that deplete the ozone. In addition to fueling the argument that it isn’t a PFAS, this characteristic is also why the company goes further to say it can actually help fight global warming. It has a far lower warming potential than traditional coolants, which Chemours said in its sustainability report released last week is helping it to reduce its scope 3 emissions.
But this is also where things start to get tricky. Remember those two ultra-short-chain PFAS Opteon 2P50 breaks down into: PFPrA and TFA? The pair are “known for their high mobility in water and difficulty to contain and remediate, resulting in their ubiquitous presence, widespread contamination, and substantial risks to human health and the environment,” Earthjustice said in its public comment. The organization further cites the European Chemicals Agency’s June decision to classify TFA as a reproductive toxin that “may damage fertility.”
“Assuming [Opteon 2P50 is] used, it will be released into the environment, go into the upper atmosphere, and break down and spread TFA on the landscape,” Siegel told me. Its main pathway into humans is through uptake by plants that we or other animals eat; TFA has been detected across food types, one study found, including in bananas, tomatoes, muffins, chicken breast, and wheat.
But Mads Sulbaek Andersen, a professor of chemistry at California State University, Northridge, whose research on TFA Earthjustice cites in its filing to the EPA, told me he thinks the opposition has blown the danger way out of proportion. “You will find people in industry saying sometimes that TFA is not a problem because it is not toxic,” he said. “I would say that’s not quite correct. Everything is toxic [in large enough amounts], but the risk that we see from TFA is not worth worrying about.”
Sulbaek Andersen is a panel member for the United Nations Environmental Program under the Montreal Protocol, which recently concluded an update to the parties on the state of the environment and the gases being used as replacements for the old ozone-depleting CFCs. During its review, which projected how TFA is likely to accumulate in the environment through 2100, “the conclusion is that the risk to environmental health and human health is de minimis,” he told me. He further told me that he thinks the European Chemicals Agency made a mistake in defining TFA as toxic at all, basing its decision on what he described as a “problematic study” with “laboratory issues,” and that Earthjustice, by extension, is overreacting to the Opteon 2P50 filing. (Some research has linked TFA exposure to eye and skeletal abnormalities in rabbit offspring, though animal studies are not necessarily indicative of toxicity to humans.)
“They’re saying that the EPA shouldn’t approve it because it’s a PFAS? That statement is nonsense,” he told me when I asked him about it. “You can decide that you don’t want any PFAS [approved], but that’s not founded in science — that’s just opinion.”
Not everyone in his field agrees. Hans Peter Arp, an environmental chemist at the Norwegian Geotechnical Institute, is the lead author of a 2024 paper that describes the buildup of TFA as an irreversible “global threat.” “It’s just a matter of time before PFAS from different sources accumulate to levels that are more concerning,” he told me. The pharmaceutical and semiconductor industries are other sources of atmospheric TFA, and it’s yet unclear how a compound like Opteon 2P50 could add to that contamination if it is widely adopted in data centers. A single immersion tank holds around 1,270 liters of fluid, and a hyperscale data center could house hundreds of tanks.
“That’s what I’m worried about in all my discussions of TFA and PFAS,” Arp went on. “That this new Opteon will be one more source, of many sources, that will lead to an accumulation that is a permanent, fixed thing. It’s not like we stop using it and it goes away. It doesn’t work like that.”
Real questions remain about the practical use of Opteon 2P50, too. As Earthjustice’s filing notes, all the data from Chemours about its use and efficiency are based on small-scale tests, and there is still “no indication it can be used at scale in data centers.” A 2016 study by the Lawrence Berkeley National Laboratory that assessed a different dielectric heat transfer fluid that was functionally analogous to Opteon 2P50, though chemically distinct, and found “significant issues with the substance and deemed its use ‘not viable at this time,’” Earthjustice’s report notes.
Chemours faces substantial competition. PFAS-free hydrocarbon, CO2 and ammonia chillers, and CO2 CRAC units “are already cooling data centers in Europe and North America efficiently,” ATMOsphere, a market accelerator for clean cooling, writes in its 2025 report. Though there are some concerns that these so-called “natural refrigerants” aren’t as effective as PFAS, “I try to emphasize that if there are safer chemicals that we can use in the production, we should favor those technologies,” Arp told me. “I know I probably can’t do much about limiting data center growth,” he went on. “But we can at least try to make them in as environmentally sustainable a way as possible, such as using geothermal energy — and using cooling systems that do not require PFAS.”
Though Sulbaek Andersen insisted on avoiding the clumsy vilification of PFAS — a term that describes a molecular structure found in millions of compounds — as uniformly “bad” or “dangerous,” several U.S. states and the EU have made moves toward phasing them out. Still, given the prevailing atmosphere, Chemours’ bet on Opteon 2P50 surprised me.
But whether Opteon 2P50 is ultimately deemed unviable or quickly made obsolete by laws or competitors, it appears certain to be among the first of many data center-related chemicals and PFAS for an overtaxed and understaffed EPA to review. “I suspect there will be more chemicals coming along the pipeline,” Antezana, the Earthjustice scientist, told me, sounding weary.
Given the pressure on the EPA from the Trump administration, coupled with business-friendly exceptions for transparency around health impacts that make it difficult for watchdog groups to sound the alarm, now may be a poor time to play fast and loose with a substance that could end up in the environment forever.
As Arp, the environmental chemist, warned, the agency needs to get a decision on a chemical like Opteon 2P50 right the first time; if toxicology studies later confirm serious human health impacts of TFA, it would be too late to backtrack. “This is something we’ve gotten to too late, too often,” he said.
On British nuclear, Puerto Rican water, and the U.S. solar supply chain
Current conditions: Dolly is no longer a tropical storm, but the remnants of the system are set to drench the northern Caribbean, especially the Leeward Islands, the British and U.S. Virgin Islands, and eastern Puerto Rico • One person died and at least 14 hikers are missing in flash floods in the Grand Canyon that forced airlifts on Sunday • In the Pacific, Tropical Storm Karina is rapidly strengthening into a hurricane, but it’s unlikely to make landfall anywhere.
The United States has brokered what President Donald Trump called “the biggest oil deal in world history” with Venezuela, securing majority control over more than 65 million barrels of the South American nation’s proven supply of crude. In a post on his Truth Social network Friday evening, Trump said the agreement would “more than double American oil reserves” and “substantially lower gas prices for all Americans, long into the future, while helping to continue to set Venezuela on a course toward tremendous success and great prosperity.” Appearing on national television for a six-minute address, Venezuela’s interim President Delcy Rodríguez, who took power after the U.S. captured former leader Nicolás Maduro in a night-time raid nearly nine months ago, said the pact would allow Caracas to earn more than $209 billion in revenue and become “an energy powerhouse.” While “everyone knows our country has the biggest oil reserves in the world,” she said, “having resources underground isn’t enough.” She added, according to The Guardian’s translation: “It’s no use having our oil resources underground, only to appear in statistics or bookkeeping.” The deal is good news for the string of U.S. oil refineries on the Gulf coast that were designed for the heavy crude that comes out of Venezuela. As it stands, my colleague Matthew Zeitlin wrote last week, “America’s oil refineries are going all out.”
For all the fears stirred up by Central Intelligence Agency Director John Ratcliffe’s recent surprise visit to Moscow — remember, the last two times an American spy chief went to Russia, it was to try to dissuade the Kremlin from invading Ukraine or commit the first war-time nuclear bombing since World War II — the country doesn’t seem particularly ready to, as The Wall Street Journal reported, risk war with Washington by attacking a North Atlantic Treaty Organization country. Russia’s gasoline production fell to about 70% of domestic consumption levels in August following a series of Ukrainian drone attacks that forced major refineries offline, two industry sources told Reuters.
In June, New York led Northeast states in filing a lawsuit against the Trump administration, challenging the deals the Department of the Interior struck with offshore wind developers to pay out billions in taxpayer-funded “settlements” in exchange for abandoning the already-stalled turbine projects. Now California has filed its own lawsuit over what Attorney General Rob Bonta called the administration’s “blatantly unlawful” buyout of wind leases off the state’s coast. “The Trump administration’s backroom buyout with Golden State Wind to stop offshore wind development in favor of gas and oil drilling is, unfortunately, a classic playbook for them to line the pockets of their Big Oil donors,” Bonta said in a statement. “Let’s be clear: California will continue to aggressively fight back against the Trump administration’s outrageous abuse of taxpayer dollars to abandon offshore wind investments that could have delivered union-paying jobs and reliable clean energy to Californians.” The California Energy Commission, which joined the lawsuit, called the Interior Department’s efforts to curb offshore wind development “reckless” in the face of rising electricity demand. Adding to the malcontent over President Donald Trump’s most fruitful effort yet to kill off a specific clean energy sector that has drawn his ire since before he entered politics, my colleague Robinson Meyer noted earlier this month that the deals — more of which have come since the California settlement — are all for projects that were unlikely to move forward anyway.

Until 1991, the United States produced the majority of the uranium its reactors (and atomic war machine) needed. Then came “megatons to megawatts.” Under the pithily named program, the U.S. took a victory lap after winning the Cold War by agreeing to import virtually any reactor fuel Russia made from disassembled weapons. American power plants received cheap fuel, a chaotically marketizing Russia found a market for some of its most coveted materials, and the world averted nuclear apocalypse. The only problem is that, contrary to the rhetoric of the time, history didn’t end. What nearly did end was domestic production of uranium and reactor fuel as Russian imports put American suppliers out of business. Nearly four decades later, the U.S. has banned Russian imports, and the exemptions to the prohibition end in 2028. The good news is that the U.S. is stepping up. In 2025, uranium concentrate production totaled 2.1 million pounds of triuranium octoxide — the base component for reactor fuel, known as yellowcake. That, according to the latest U.S. Energy Information Administration analysis, is the most since 2017 and more than triple the volume produced in 2024. But it’s still far from enough for energy independence. U.S. power plants used nearly 47 million pounds of yellowcake in 2025, down from just under 56 million pounds in 2024. Regardless of whether all the reactors currently underway move forward, that number is going up. New supply is coming. On Friday, developer Anfield Energy told The Northern Miner that it’s seeking to raise at least $50 million in financing in the coming months to refurbish and reopen Utah’s Shootaring Canyon mill, one of only three licensed, permitted, and constructed uranium mills in the U.S.

The U.S. supply boost could also benefit the United Kingdom, which is working with Washington on spurring along its own nuclear renaissance. A new YouGov poll released Friday found nuclear power to be Britain’s preferred future electricity source, with 21% of Britons saying it should be prioritized, compared to 19% for solar and 18% for offshore wind. Just over half of the voters surveyed doubted renewables alone could provide enough electricity to meet the nation’s power demand and lower costs. That’s despite nearly 50 gigawatts of onshore wind in the development pipeline across Great Britain, according to Renewables Now.

Britons’ doubts over renewables come as England’s water network heaves under the stress of a severe “flash drought” that Bloomberg said “is showing no signs of easing,” forcing water companies to truck supplies in and call for emergency restrictions. At least 30 million now face a temporary ban on using hoses and outdoor pipes.
Nearly 200,000 households and businesses are still without steady access to running water in Puerto Rico, where drought has collided with an aging aquifer system that leaks, by some estimates, more than half its supply of freshwater. Climate change reduced rainfall in America’s most populous non-state territory by 9% between May and July of this year, according to a new study by more than 20 scientists worldwide. The conclusion, the San Juan-based Centro de Periodismo Investigativo reported, is that drought “will persist and worsen.”
Earlier this month, as my colleague Emily Pontecorvo and I reported, the Trump administration tossed solar manufacturers a lifeline, raising tariffs on imported panel components in a bid to help factories compete with imports after Republicans’ sweeping tax law eliminated the federal incentives for developers to buy American-made photovoltaics. Since then, analysts have debated whether the minimum prices set in the Department of Commerce’s policy are sufficient to spur new investments in the production of solar cells. At least one company is announcing a project. In a post on LinkedIn last week, Oklahoma City-based Nextnova Solar unveiled plans for a 2-gigawatt solar cell factory in its home state. The company expects to bring the facility online in November and begin mass production in March 2027, according to PV Tech, which noted the possibility to expand to 5 gigawatts of annual production sometime in the future.
Meanwhile, the Minnesota-based manufacturer Heliene is preparing for a trial run of panels using American-made glass. The company has 1.3 gigawatts of crystalline silicon module capacity production, and recently formed a partnership to secure more locally sourced wafers and cells. But U.S.-made glass “has so far been a key missing element,” PV Tech reported in a separate story. Heliene’s pilot run will use glass from Ohio-based Stewart Glass. “As U.S. module manufacturing has been growing, there has been no supply of non-iron content glass,” Heliene CEO Martin Pochtaruk told the trade publication. “Being able to use glass versus importing glass is also part of de-risking the geopolitics of imports from Asia, and that’s why it’s so important.”
In the U.S., we are still working our heads around building out a charging network that can comfortably keep electric cars fueled up from coast to coast with the same ease as a vehicle that can just fill up at a gas station. In China, auto giant BYD is now rolling out its ultra-fast chargers, which can restore a vehicle’s battery as quickly as you can fill up a gas tank. Just a few months ago, BYD marked its 5,000th Flash Charger deployment. Now it’s up to 10,000 across 300 different centers, InsideEVs reported last week, cribbing from the Chinese news site IT Home.
And more thoughts on the week’s most notable fights around project development.
1. Pinal County, Arizona – If you can’t build a solar or a wind farm somewhere, it’s really hard to get a data center built there too.
2. St. Joseph County, Indiana – Thousands of miles away from Arizona, a similar division is dominating the fight over whether to enact a 2-year moratorium on data centers in the county home of South Bend.
3. Ingham County, Michigan – The first solar farm fight has been resolved under Michigan’s new renewables siting law.
