The science is still out — but some of the industry’s key players are moving ahead regardless.
A conversation with Mary King, a vice president handling venture strategy at Aligned Capital
Wind and solar are out. Clean, firm power is in.
How the perpetually almost-there technology could get shut out of the Inflation Reduction Act’s surviving nuclear tax credits.
The company is well-positioned to take advantage of Trump’s nuclear policies, include his goal of installing a microreactor on a military base within the next few years.
The new funding comes as tax credits for geothermal hang in the balance.
The good news is pouring in for the next-generation geothermal developer Fervo Energy. On Tuesday the company reported that it was able to drill its deepest and hottest geothermal well to date in a mere 16 days. Now on Wednesday, the company is announcing an additional $206 million in financing for its Cape Station project in Utah.
With this latest tranche of funding, the firm’s 500-megawatt development in rural Beaver County is on track to deliver 24/7 clean power to the grid beginning in 2026, reaching full operation in 2028. The development is shaping up to be an all-too-rare phenomenon: A first-of-a-kind clean energy project that has remained on track to hit its deadlines while securing the trust of institutional investors, who are often wary of betting on novel infrastructure projects.
The bulk of this latest financing comes from the Bill Gates-backed Breakthrough Energy Catalyst program, which provided $100 million in project-level equity funding. The energy and commodity trading company Mercuria provided $60 million in corporate loans, increasing its existing fixed-term loan from $40 million to $100 million. An additional $45.6 million in short-term debt financing came from XRL-ALC, an affiliate of X-Caliber Rural Capital, which provides loans to infrastructure projects in rural areas. That comes on top of a previous $100 million loan from the firm.
The plan is for Cape Station to deliver 100 megawatts of grid power in 2026, with the additional 400 megawatts by 2028. The facility has the necessary permitting to expand production to two gigawatts — twice the size of a standard nuclear reactor. And on Monday, the company announced that an independent report from the consulting firm DeGolyer & MacNaughton confirms that the project could expand further still — eventually supporting over 5 gigawatts of clean power at depths of up to 13,000 feet. The company’s latest drilling results, which reached 15,765 feet at 520 degrees Fahrenheit, could push the project’s potential power output even higher.
Traditional geothermal wells normally max out at around 10,000 feet, and must be built in locations where a lucky confluence of geological features come together: high temperatures, porous rock, and naturally occurring water or steam. But because Fervo can drill thousands of feet deeper, it’s able to access hot rocks in locations that weren’t previously suitable for geothermal development, pumping high-pressure water down into the wells to fracture rocks and thus create its own geothermal reservoirs.
The primary customer for Fervo’s Cape Station project is Southern California Edison, which signed a 320-megawatt power purchase agreement with the company last year, advertised as the largest geothermal PPA ever. Shell was also announced as a customer this year. Fervo is already providing 3.5 megawatts of power to Google via a pilot project in Nevada, which it’s seeking to expand, entering into a 115 megawatt PPA with NV Energy and the tech giant to further build out production at this location.
Fervo’s latest funding comes on top of last February’s $244 million Series D round led by Devon Energy, as well as an additional $255 million in corporate equity and debt financing that it announced last December. On top of investments from well known climate tech venture firms such as Breakthrough Energy Ventures and Galvanize Climate Solutions, the company has secured institutional investment from Liberty Mutual as well as public pension funds such as the California State Teachers’ Retirement System and the Canada Pension Plan Investment Board.
Fervo, like all clean energy startups, also stands to benefit greatly from the Inflation Reduction Act’s clean energy tax credits, which are now in jeopardy as President Trump’s One Big, Beautiful Bill works its way through the Senate. While Secretary of Energy Chris Wright has traditionally been a booster of geothermal energy and is advocating to keep tax incentives for the technology in place through 2031, the bill as it stands would essentially erase incentives for all geothermal projects that start construction more than 60 days after the bill’s passage.
Fervo broke ground on Cape Station in 2023, so that project will make the cut. For future Fervo developments, it’s much less clear. But for now, the company seems to be flush with cash and potential in a climate tech world awash in ill omens.
Secretary of Energy Chris Wright canceled 24 decarbonization grants worth $3.7 billion.
Secretary of Energy Chris Wright is clawing back 24 grants for projects to cut emissions from heavy industry after signaling earlier this month that he was reviewing the Biden administration’s award decisions. The total lost funding comes to just over $3.7 billion, and would have helped a wide range of companies, including those in food and beverage production, steelmaking, cement, and chemicals deploy cutting edge clean energy solutions.
The agency, however, decided that the projects “failed to advance the energy needs of the American people, were not economically viable and would not generate a positive return on investment of taxpayer dollars,” according to the announcement.
Most of the cancelled projects were part of the Industrial Demonstration Program, which was created by the Inflation Reduction Act and designed to help commercialize decarbonization solutions that were past the early experimental stage, but were also not quite ready for mass deployment.
Proponents of the program found the DOE’s decision outrageous. “They’re not building an economy — they’re dismantling it and giving away the future of manufacturing,” Evan Gillespie, a partner at the advocacy group Industrious Labs, said in a statement. Canceling these projects is “handing the competitive advantage to Europe, China, Canada, and other nations that are making significant investments in clean manufacturing while leaving the U.S behind,” he added.
The Kraft Heinz Food Company, for example, was supposed to get $172 million to swap out fossil fuel-fired boilers and other heating equipment for electric heat pumps and solar thermal systems at 10 of its factories. “This project seeks to help a major American brand achieve deep decarbonization and serve as an example for other U.S. food and beverage companies to reduce emissions from process heat while reducing energy costs,” the original award from the DOE said. Diageo, the liquor conglomerate, and Kohler, the kitchen and bathroom appliance brand, were also among the awardees.
Cement production is one of the biggest sources of industrial emissions in the world, and also among the most difficult to decarbonize due to an integral chemical reaction that releases carbon into the atmosphere regardless of whether the plant burns fossil fuels. Experts aren’t sure yet what the best solution will be, and the DOE program awarded a variety of projects to test different pathways.
Heidelberg Materials, one of the largest cement companies in the world, was going to get $500 million to demonstrate the first cement plant to capture and sequester its carbon emissions in the U.S. A company called Sublime Systems that’s using an alternative chemistry and electric currents to make cement was supposed to receive $87 million to build its first commercial-scale factory in Holyoke, Massachusetts. Just last week, Sublime signed a deal to supply 623,000 metric tons of zero-carbon cement to Microsoft, in part to support the tech giant’s data center buildout. Another company called Brimstone was awarded $189 million to produce low-carbon cement alongside alumina, the base material used to make aluminum.
“Given our project's strong alignment with President Trump's priority to increase U.S. production of critical minerals, we believe this was a misunderstanding,” a spokesperson for Brimstone told me. “Brimstone's Rock Refinery represents the only economically viable way to produce the critical mineral alumina in the U.S. from U.S.-mined rocks. As the first U.S.-based alumina plant in a generation, our project — which would also make Portland cement — would clear a 'mine-to-metal' path for U.S. aluminum production, fortifying the U.S. critical mineral supply chain and creating thousands of jobs.”
Sublime also shared a statement asserting that its technology would enable the Trump administration’s priorities. “We continue our bipartisan appeal to leaders who recognize that investing in American-invented breakthrough industrial technologies can address multiple policy priorities in tandem to the benefit of Americans from all walks of life,” Sublime said. The company added that it has “prepared for the possibility of this disappointing outcome” and is “evaluating various scenarios that leave our scale-up unimpeded.”
Oil and gas companies were also hit. A $332 million grant to help Exxon switch to low-carbon hydrogen at one of its refineries was canceled, as were $540 million in grants for the energy company Calpine to install carbon capture on its natural gas plants.
“It is hugely disappointing to see these projects canceled — projects that had already progressed through a rigorous, months-long review process by technical experts at DOE,” Jessie Stolark, the executive director of the Carbon Capture Coalition, said in a statement. While Wright said the terminations would generate taxpayer savings, Stolark argued they were depriving Americans of economic benefits. “Every dollar invested by the American taxpayer can lead to up to $4 in economic output through additional supply and material orders, job creation, and broader economic benefits to regional economies,” she wrote, citing a Department of Energy-authored analysis.
None of the awardees responded to my inquiry as to whether they would consider pursuing legal challenges. According to the law under which the program was created, the funding was to be awarded “on a competitive basis,” based on the expected greenhouse gas emission reductions from the project and its potential to provide the greatest benefit to the greatest number of people. Additional criteria in the agency’s application process said it would evaluate projects based on the “degree to which the applicant assesses and demonstrates potential market competitiveness and sustainability for the proposed project, technology, and manufactured product(s) through market analysis and offtake agreements.”
Notably absent from the list of canceled projects is a grant for the steelmaking company Cleveland Cliffs. Earlier this month, I reported that the company was renegotiating its award under the Industrial Demonstration Program. On an earnings call, its CEO said it was abandoning plans to use clean energy and instead looking to use the funds to extend the life of its fossil fuel-fired blast furnace.
If gone unchallenged, the funding is not likely to be re-awarded to other projects. The budget bill that is currently working its way through Congress would rescind any money from the Industrial Demonstrations Program that isn’t under contract.
