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.”

Agriculture startups are suddenly some of the hottest bets in climate tech, according to the results of our Insiders Survey.
Innovations in agriculture can seem like the neglected stepchild of the climate tech world. While food and agriculture account for about a quarter of global emissions, there’s not a lot of investment in the space — or splashy breakthroughs to make the industry seem that investible in the first place. In transportation and energy, “there is a Tesla, there is an EnPhase,” Cooper Rinzler, a partner at Breakthrough Energy Ventures, told me. “Whereas in ag tech, tell me when the last IPO that was exciting was?”
That may be changing, however. Multiple participants in Heatmap’s Insiders Survey cited ag tech companies Pivot Bio and Nitricity — both of which are pursuing alternate approaches to conventional ammonia-based fertilizers — as among the most exciting climate tech companies working today.
Studies estimate that fertilizer production and use alone account for roughly 5% of global emissions. That includes emissions from the energy-intensive Haber–Bosch process, which synthesizes ammonia by combining nitrogen from the air with hydrogen at extremely high temperatures, as well as nitrous oxide released from the soil after fertilizer is applied. N2O is about 265 times more potent than carbon dioxide over a 100-year timeframe and accounts for roughly 70% of fertilizer-related emissions, as soil microbes convert excess nitrogen that crops can’t immediately absorb into nitrous oxide.
“If we don’t solve nitrous oxide, it on its own is enough of a radiative force that we can’t meet all of our goals,” Rinzler said, referring to global climate targets at large.
Enter what some consider one of the most promising agricultural innovations, perhaps since the invention of the Haber–Bosch process itself over a century ago — Pivot Bio. This startup, founded 15 years ago, engineers soil microbes to convert about 400 times more atmospheric nitrogen into ammonia than non-engineered microbe strains naturally would. “They are mini Haber–Bosch facilities, for all intents and purposes,” Pivot Bio’s CEO Chris Abbott told me, referring to the engineered microbes themselves.
The startup has now raised over $600 million in total funding and is valued at over $2 billion. And after toiling in the ag tech trenches for a decade and a half, this will be the first full year the company’s biological fertilizers — which are applied to either the soil or seed itself — will undercut the price of traditional fertilizers.
“Farmers pay 20% to 25% less for nitrogen from our product than they do for synthetic nitrogen,” Abbott told me. “Prices [for traditional fertilizers] are going up again this spring, like they did last year. So that gap is actually widening, not shrinking.”
Peer reviewed studies also show that Pivot’s treatments boost yields for corn — its flagship crop — while preliminary data indicates that the same is true forcotton, which Pivot expanded into last year. The company also makes fertilizers for wheat, sorghum, and other small grains.
Pivot is now selling these products in stores where farmers already pick up seeds and crop treatments, rather than solely through its independent network of sales representatives, making the microbes more likely to become the default option for growers. But they won’t completely replace traditional fertilizer anytime soon, as Pivot’s treatments can still meet only about 20% to 25% of a large-scale crop’s nitrogen demand, especially during the early stages of plant growth, though it’s developing products that could push that number to 50% or higher, Abbott told me.
All this could have an astronomical environmental impact if deployed successfully at scale. “From a water perspective, we use about 1/1000th the water to produce the same amount of nitrogen,” Abbott said. From an emissions perspective, replacing a ton of synthetic nitrogen fertilizer with Pivot Bio’s product prevents the equivalent of around 11 tons of carbon dioxide from entering the atmosphere. Given the quantity of Pivot’s fertilizer that has been deployed since 2022, Abbott estimates that scales to approximately 1.5 million tons of cumulative avoided CO2 equivalent.
“It’s one of the very few cases that I’ve ever come across in climate tech where you have this giant existing commodity market that’s worth more than $100 billion and you’ve found a solution that offers a cheaper product that is also higher value,” Rinzler told me. BEV led the company’s Series B round back in 2018, and has participated in its two subsequent rounds as well.
Meanwhile, Nitricity — a startup spun out of Stanford University in 2018 — is also aiming to circumvent the Haber–Bosch process and replace ammonia-based and organic animal-based fertilizers such as manure with a plant-based mixture made from air, water, almond shells, and renewable energy. The company said that its proprietary process converts nitrogen and other essential nutrients derived from combusted almond shells into nitrate — the form of nitrogen that plants can absorb. It then “brews” that into an organic liquid fertilizer that Nitricity’s CEO, Nico Pinkowski, describes as looking like a “rich rooibos tea,” capable of being applied to crops through standard irrigation systems.
For confidentiality reasons, the company was unable to provide more precise technical details regarding how it sources and converts sufficient nitrogen into a usable form via only air, water, and almond shells, given that shells don’t contain much nitrogen, and turning atmospheric nitrogen into a plant-ready form typically involves the dreaded Haber–Bosch process.
But investors have bought in, and the company is currently in the midst of construction on its first commercial-scale fertilizer factory in Central California, which is expected to begin production this year. Funding for the first-of-a-kind plant came from Trellis Climate and Elemental Impact, both of which direct philanthropic capital toward early-stage, capital-intensive climate projects. The facility will operate on 100% renewable power through a utility-run program that allows customers to opt into renewable-only electricity by purchasing renewable energy certificates,
Pinkowski told me the new plant will represent a 100‑fold increase in Nitricity’s production capacity, which currently sits at 80 tons per year from its pilot plant. “In comparison to premium conventional fertilizers, we see about a 10x reduction in emissions,” Pinkowski told me, factoring in greenhouse gases from both production and on-field use. “In comparison to the most standard organic fertilizers, we see about a 5x reduction in emissions.”
The company says trial data indicates that its fertilizer allows for more efficient nitrogen uptake, thus lowering nitrous oxide emissions and allowing farmers to cut costs by simply applying less product. According to Pinkowski, Nitricity’s current prices are at parity or slightly lower than most liquid organic fertilizers on the market. And that has farmers really excited — the new plant’s entire output is already sold through 2028.
“Being able to mitigate emissions certainly helps, but it’s not what closes the deal,” he told me. “It’s kind of like the icing on the cake.”
Initially, the startup is targeting the premium organic and sustainable agriculture market, setting it apart from Pivot Bio’s focus on large commodity staple crops. “You saw with the electrification of vehicles, there was a high value beachhead product, which was a sports car,” Pinkowski told me. “In the ag space, that opportunity is organics.”
But while big-name backers have lined up behind Pivot and Nitricity, the broader ag tech sector hasn’t been as fortunate in its friends, with funding and successful scale-up slowing for many companies working in areas such as automation, indoor farming, agricultural methane mitigation, and lab-grown meat.
Everyone’s got their theories for why this could be, with Lara Pierpoint of Trellis telling me that part of the issue is “the way the federal government is structured around this work.” The Department of Agriculture allocates relatively few resources to technological innovation compared to the Department of Energy, which in turn does little to support agricultural work outside of its energy-specific mandate. That ends up meaning that, as Pierpoint put it, ”this set of activities sort of falls through the cracks” of the government funding options, leaving agricultural communities and companies alike struggling to find federal programs and grant opportunities.
“There’s also a mismatch between farmers and the culture of farming and agriculture in the United States, and just even geographically where the innovation ecosystems are,” Emily Lewis O’Brien, a principal at Trellis who led the team’s investment in Nitricity, told me of the social and regional divides between entrepreneurs, tech investors and rural growers. “Bridging that gap has been a little bit tricky.”
Still, investors remain optimistic that one big win will help kick the money machines into motion, and with Pivot Bio and Nitricity, there are finally some real contenders poised to transform the sector. “We’re going to wake up one day and someone’s going to go, holy shit, that was fast,” Abbott told me. “And it’s like, well you should have been here for the decade of hard work before. It’s always fast at the end.”
The most popular scope 3 models assume an entirely American supply chain. That doesn’t square with reality.
“You can’t manage what you don’t measure,” the adage goes. But despite valiant efforts by companies to measure their supply chain emissions, the majority are missing a big part of the picture.
Widely used models for estimating supply chain emissions simplify the process by assuming that companies source all of their goods from a single country or region. This is obviously not how the world works, and manufacturing in the United States is often cleaner than in countries with coal-heavy grids, like China, where many of the world’s manufactured goods actually come from. A study published in the journal Nature Communications this week found that companies using a U.S.-centric model may be undercounting their emissions by as much as 10%.
“We find very large differences in not only the magnitude of the upstream carbon footprint for a given business, but the hot spots, like where there are more or less emissions happening, and thus where a company would want to gather better data and focus on reducing,” said Steven Davis, a professor of Earth system science in the Stanford Doerr School of Sustainability and lead author of the paper.
Several of the authors of the paper, including Davis, are affiliated with the software startup Watershed, which helps companies measure and reduce their emissions. Watershed already encourages its clients to use its own proprietary multi-region model, but the company is now working with Stanford and the consulting firm ERG to build a new and improved tool called Cornerstone that will be freely available for anyone to use.
“Our hope is that with the release of scientific papers like this one and with the launch of Cornerstone, we can help the ecosystem transition to higher quality open access datasets,” Yohanna Maldonado, Watershed’s Head of Climate Data told me in an email.
The study arrives as the Greenhouse Gas Protocol, a nonprofit that publishes carbon accounting standards that most companies voluntarily abide by, is in the process of revising its guidance for calculating “scope 3” emissions. Scope 3 encompasses the carbon that a company is indirectly responsible for, such as from its supply chain and from the use of its products by customers. Watershed is advocating that the new standard recommend companies use a multi-region modeling approach, whether Watershed’s or someone else’s.
Davis walked me through a hypothetical example to illustrate how these models work in practice. Imagine a company that manufactures exercise bikes — it assembles the final product in a factory in the U.S., but sources screws and other components from China. The typical way this company would estimate the carbon footprint of its supply chain would be to use a dataset published by the U.S. Environmental Protection Agency that estimates the average emissions per dollar of output for about 400 sectors of the U.S. economy. The EPA data doesn’t get down to the level of detail of a specific screw, but it does provide an estimate of emissions per dollar of output for, say, hardware manufacturing. The company would then multiply the amount of money it spent on screws by that emissions factor.
Companies take this approach because real measurements of supply chain emissions are rare. It’s not yet common practice for suppliers to provide this information, and supply chains are so complex that a product might pass through several different hands before reaching the company trying to do the calculation. There are emerging efforts to use remote sensing and other digital data collection and monitoring systems to create more accurate, granular datasets, Alexia Kelly, a veteran corporate sustainability executive and current director at the High Tide Foundation, told me. In the meantime, even though sector-level emissions estimates are rough approximations, they can at least give a company an indication of which parts of their supply chain are most problematic.
When those estimates don’t take into account country of origin, however, they don’t give companies an accurate picture of which parts of their supply chains need the most attention.
The new study used Watershed’s multi-region model to look at how different types of companies’ emissions would change if they used supply chain data that better reflected the global nature of supply chains. Davis is the first to admit that the study’s findings of higher emissions are not surprising. The carbon accounting field has long been aware of the shortcomings of single-region models. There hasn’t been a big push to change that, however, because the exercise is already voluntary and taking into account global supply chains is significantly more difficult. Many countries don’t publish emissions and economic data, and those that do use a variety of methods to report it. Reconciling those differences adds to the challenge.
While the overall conclusion isn’t surprising, the study may be the first to show the magnitude of the problem and illustrate how more accurate modeling could redirect corporate sustainability efforts. “As far as I know, there is no similar analysis like this focused on corporate value chain emissions,” Derik Broekhoff, a senior scientist at the Stockholm Environment Institute, told me in an email. “The research is an important reminder for companies (and standard setters like the Greenhouse Gas Protocol), who in practice appear to be overlooking foreign supply chain emissions in large numbers.”
Broekhoff said Watershed’s upcoming open-source model “could provide a really useful solution.” At the same time, he said, it’s worth noting that this whole approach of calculating emissions based on dollars spent is subject to significant uncertainty. “Using spending data to estimate supply chain emissions provides only a first-order approximation at best!”
The decision marks the Trump administration’s second offshore wind defeat this week.
A federal court has lifted Trump’s stop work order on the Empire Wind offshore wind project, the second defeat in court this week for the president as he struggles to stall turbines off the East Coast.
In a brief order read in court Thursday morning, District Judge Carl Nichols — a Trump appointee — sided with Equinor, the Norwegian energy developer building Empire Wind off the coast of New York, granting its request to lift a stop work order issued by the Interior Department just before Christmas.
Interior had cited classified national security concerns to justify a work stoppage. Now, for the second time this week, a court has ruled the risks alleged by the Trump administration are insufficient to halt an already-permitted project midway through construction.
Anti-offshore wind activists are imploring the Trump administration to appeal this week’s injunctions on the stop work orders. “We are urging Secretary Burgum and the Department of Interior to immediately appeal this week’s adverse federal district court rulings and seek an order halting all work pending appellate review,” Robin Shaffer, president of Protect Our Coast New Jersey, said in a statement texted to me after the ruling came down.
Any additional delays may be fatal for some of the offshore wind projects affected by Trump’s stop work orders, irrespective of the rulings in an appeal. Both Equinor and Orsted, developer of the Revolution Wind project, argued for their preliminary injunctions because even days of delay would potentially jeopardize access to vessels necessary for construction. Equinor even told the court that if the stop work order wasn’t lifted by Friday — that is, January 16 — it would cancel Empire Wind. Though Equinor won today, it is nowhere near out of the woods.
More court action is coming: Dominion will present arguments on Friday in federal court against the stop work order halting construction of its Coastal Virginia offshore wind project.
