Houston-based Fervo Energy closes $462M series E

fresh funding

Houston-based geothermal energy company Fervo Energy has closed an oversubscribed $462 million series E funding round, led by new investor B Capital.

“Fervo is setting the pace for the next era of clean, affordable, and reliable power in the U.S.,” Jeff Johnson, general partner at B Capital, said in a news release. “With surging demand from AI and electrification, the grid urgently needs scalable, always-on solutions, and we believe enhanced geothermal energy is uniquely positioned to deliver. We’re proud to support a team with the technical leadership, commercial traction, and leading execution capabilities to bring the world’s largest next-generation geothermal project online and make 24/7 carbon-free power a reality.”

The financing reflects “strong market confidence in Fervo’s opportunity to make geothermal energy a cornerstone of the 24/7 carbon-free power future,” according to the company. The round also included participation from Google, a longtime Fervo Partner, and other new and returning investors like Devon Energy, Mitsui & Co., Ltd., Mitsubishi Heavy Industries and Centaurus Capital. Centaurus Capital also recently committed $75 million in preferred equity to support the construction of Cape Station Phase I, Fervo noted in the release.

The latest funding will support the continued buildout of Fervo’s Utah-based Cape Station development, which is slated to start delivering 100 MW of clean power to the grid beginning in 2026. Cape Station is expected to be the world's largest next-generation geothermal development, according to Fervo. The development of several other projects will also be included in the new round of funding.

“This funding sharpens our path from breakthrough technology to large-scale deployment at Cape Station and beyond,” Tim Latimer, CEO and co-founder of Fervo, added in the news release. “We’re building the clean, firm power fleet the next decade requires, and we’re doing it now.”

Fervo recently won Scaleup of the Year at the 2025 Houston Innovation Awards, and previously raised $205.6 million in capital to help finance the Cape Station earlier this year. The company fully contracted the project's capacity with the addition of a major power purchase agreement from Shell this spring. Fervo’s valuation has been estimated at $1.4 billion and includes investments and support from Bill Gates.

“This new investment makes one thing clear: the time for geothermal is now,” Latimer added in a LinkedIn post. “The world desperately needs new power sources, and with geothermal, that power is clean and reliable. We are ready to meet the moment, and thrilled to have so many great partners on board.”

Fervo named to prestigious list of climate tech companies to watch

top honor

Houston-based Fervo Energy has received yet another accolade—MIT Technology Review named the geothermal energy startup to its 2025 list of the 10 global climatetech companies to watch.

Fervo, making its second appearance on the third annual list, harnesses heat from deep below the ground to generate clean geothermal energy, MIT Technology Review noted. Fervo is one of four U.S. companies to land on the list.

Fervo “uses fracking techniques to create geothermal reservoirs capable of delivering enough electricity to power massive data centers and hundreds of thousands of homes,” MIT Technology Review said.

MIT Technology Review said it produces the annual list to draw attention to promising climatetech companies that are working to decarbonize major sectors of the economy.

“Though the political and funding landscape has shifted dramatically in the US since the last time we put out this list,” MIT Technology Review added, “nothing has altered the urgency of the climate dangers the world now faces — we need to rapidly curb greenhouse gas emissions to avoid the most catastrophic impacts of climate change.”

In addition to MIT Technology Review’s companies-to-watch list, Fervo has appeared on similar lists published by Inc.com, Time magazine and Climate Insider.

In an essay accompanying MIT Technology Review’s list, Microsoft billionaire Bill Gates said his Breakthrough Energy Ventures investment group has invested in more than 150 companies, including Fervo and another company on the MIT Technology Review list, Redwood Materials.

In his essay, Gates wrote that ingenuity is the best weapon against climate change.

Yet climate technology innovations “offer more than just a public good,” he said. “They will remake virtually every aspect of the world’s economy in the coming years, transforming energy markets, manufacturing, transportation, and many types of industry and food production. Some of these efforts will require long-term commitments, but it’s important that we act now. And what’s more, it’s already clear where the opportunities lie.”

In a recent blog post highlighting Fervo, Gates predicted geothermal will eventually supply up to 20 percent of the world’s electricity, up from his previous estimate of as much as 5 percent.

Fervo is one of the pioneers in geothermal energy. Gates and other investors have pumped $982 million into Fervo since its founding in 2017. With an estimated valuation of $1.4 billion, Fervo has achieved unicorn status, meaning its valuation as a private company exceeds $1 billion.

Aside from Breakthrough Energy Ventures, oilfield services provider Liberty Energy is a Fervo investor. U.S. Energy Secretary Chris Wright was chairman and CEO of Denver-based Liberty Energy before assuming his federal post.

Axios reported on Oct. 1 that Fervo is raising a $300 million series E round, which would drive up the startup’s valuation. News of the $300 million round comes as the company gears up for a possible IPO, according to Axios.

Fervo co-founder and CEO Tim Latimer told Axios this spring that a potential IPO is likely in 2026 or 2027. Ahead of an IPO, the startup is aiming for a $2 billion to $4 billion valuation, Axios reported.

The first phase of Fervo’s marquee Cape Station geothermal energy plant in Utah is scheduled to go online next year, with the second phase set to open in 2028. Once it’s completed, the plant will be capable of generating 500 megawatts of power. This summer, the startup said it secured $205.6 million in capital to finance construction of the plant.

geothermal predictions

In a new blog post spotlighting Houston-based geothermal power startup Fervo Energy, billionaire Bill Gates — a Fervo investor — predicts geothermal will eventually supply up to 20 percent of the world’s electricity, up from his previous estimate of as much as 5 percent.

Today, geothermal accounts for less than 1 percent of electricity generated around the world, according to the International Energy Agency. The agency forecasts geothermal will represent up to 15 percent of global power by 2050.

“Geothermal power will have a big role to play in our clean energy future, and it’s exciting to see companies like Fervo push the technology to new depths,” Gates wrote.

Gates’ more than $1 billion Breakthrough Energy Ventures fund has contributed to the $982 million pool of money that Fervo has raised since its founding in 2017. Fervo is now a unicorn, meaning its valuation as a private company exceeds $1 billion. Its valuation has been estimated at $1.4 billion.

The Microsoft billionaire published the blog post on his Gates Notes website after touring the site of Fervo’s Cape Station geothermal project, which is under construction in Utah. Fervo says Cape Station will be the world’s largest geothermal plant, capable of someday producing up to 2 gigawatts of power.

Earlier this year, Fervo raised $206 million to put toward the development of Cape Station. Of that amount, $100 million came from Breakthrough Energy Catalyst, a green tech investment program backed by Gates, according to Inc.com.

The first phase of Cape Station is scheduled to be completed in 2026, with first-year power generation pegged at 100 megawatts. An additional 500 megawatts of power-producing capacity is slated to go online in 2028.

“Geothermal is one of the most promising ways to deliver clean energy that’s reliable and affordable,” Gates wrote.

In the blog post, Gates praised the simplicity of geothermal energy.

“The interior of the Earth is incredibly hot, and the deeper you go, the hotter the ground becomes,” he explained. “If you pump fluid deep enough to be warmed by this heat and then pump it back to the surface, you can turn the hot liquid into steam and use it to spin turbines and generate electricity — just like many other types of power plants.”

Gates noted that horizontal drilling is one of Fervo’s biggest innovations. The company extends its wells horizontally by as much as 5,000 feet at the deepest point. It couples horizontal drilling with hydraulic fracturing, or fracking, to extract geothermal energy from rock formations.

Most wells at Cape Station are 8,000 to 9,000 feet deep, and the deepest one is 15,000 feet below the surface, Gates pointed out.

Gates also emphasized the water-conserving, closed-system setup at Cape Station.

“Geothermal energy is one of the more climate-friendly sources of power, but one of its downsides is how much water it uses. … Fervo’s technology captures all the water that would’ve been lost and recirculates it underground to keep the system running,” he wrote.

Bill Gates talks AI, future of energy at CERAWeek address in Houston

overheard

Bill Gates, renowned co-founder of Microsoft and founder of Breakthrough Energy, took the CERAWeek stage to a standing-room-only crowd to discuss his thoughts on the future of energy.

He was joined in conversation with Daniel Yergin, author and vice chairman of S&P Global, at the luncheon on Thursday, March 21. His remarks touched on three themes within the energy transition.

Texas as a hub for energy transition

Yergin started off the conversation inquiring about Gates and his recent tour around Texas, which included visiting energy companies' plants and facilities and their local communities. Though it might surprise people, given the history of oil and gas in the state, Texas has a strong presence in the energy transition, Gates says.

“There is some irony in the fact that so many of the capabilities to embrace (the energy transition) are here in Texas, whether it's the workforce or the permitting,” he says at the event.

Gates adds that while most of the portfolio companies at Breakthrough Energy were founded on the coasts, many turn to Texas when it comes time for their first commercial pilot.

He addressed a progress report on the energy transition as a whole.

“It’s really starting to move. There’s a lot of exciting technologies, and a lot of the big companies are coming in,” he says, specifically noting energy companies' presence at COP28.

“A heroic effort is beginning — I’m very excited about it. But we shouldn’t underestimate how difficult it will be,” he says. “There’s a lot of things that have to happen for these projects to go ahead. It’s far more difficult than anything I worked on at Microsoft.”

Steel and nuclear have big potential for disruption

Gates continued this thought but highlighting that some industries are less advanced than others.

“We’re just at the beginning of many things," he adds, noting that "the steel industry today is 99 percent the traditional process."

With that, steel has a lot of potential to be disrupted, and Breakthrough Energy has two companies working to make the industry greener, but it's an industry that's going to take time to evolve.

Nuclear is another sector Gates is excited about but is developing at a slower pace. Breakthrough Energy has five portfolio companies focused on Nuclear, including TerraPower, which Gates co-founded in 2006.

Despite nearly two decades of development, Gates says TerraPower is a "fast-moving" nuclear company in comparison to other companies out there.

AI's impact is still to be determined

The topic of artificial intelligence inevitably came up, and Gates explains that the technology has come a long way. Microsoft owns a portion of OpenAI, which created ChatGPT. Gates says he expected AI to evolve and to be able to be programmed to understand information to take longer to develop.

“We have achieved a threshold — an unusual threshold because we know how we’ve caused the knowledge represented, but we don’t understand how at a semantic level how that knowledge is being represented,” Gates says.

AI's current applications are within white collar activities, Gates explains, citing writing a regulatory permit or looking at evidence in a lawsuit. He explains that current AI capabilities could continually grow or remain stagnant for a while, he isn't sure.

"The thing that’s daunting is we don’t know how quickly it will improve," he adds.

Gates didn't comment on energy specific AI applications but noted that AI has advanced far past robotics, which would target blue collar roles.

SLB to expand data center cooling business via $4 billion acquisition

cool deal

Houston’s SLB has announced plans to acquire German thermal management and heat exchange technology organization Kelvion for approximately $4 billion.

SLB reports in a news release that the acquisition is expected to boost its Data Center Solutions business, as thermal management technologies are key to cooling artificial-intelligence-related infrastructure. Data centers continue to pose numerous challenges, but SLB believes thermal management technology can help ease energy burdens.

“Data centers are becoming more sophisticated and energy-intensive, and customers are increasingly looking for partners that can optimize how critical systems work together across the facility and help bring new capacity online faster,” Gavin Rennick, president of SLB’s New Energy and Industrial business, said in the release. “Thermal management is central to that challenge, and this acquisition allows us to address it directly by delivering more integrated cooling solutions, accelerating innovation, optimizing thermal efficiency, and more directly embedding thermal management into our modular infrastructure offering.”

SLB will acquire Kelvion from funds managed by New York-based financial services group Apollo Global Management Inc. for approximately $3.4 billion in cash and will assume about $700 million of debt, according to the release. The deal is expected to close in Q1 of 2027.

SLB says the acquisition will help it dramatically scale revenue generated by the data center sector.

“This transaction accelerates our ambition to become an industrial technology partner to the data center industry and help customers address the growing infrastructure complexity required to scale AI,” Olivier Le Peuch, CEO of SLB, added in a news release. “Kelvion advances our path toward more integrated data center infrastructure solutions, expands our addressable market — more than doubling our revenue opportunity per gigawatt of delivered capacity — and allows us to scale both our offerings and the global reach of the business.”

SLB reports that it expects its Data Center Solutions business revenues to grow by more than 90 percent annually between 2024 and 2026.

If the acquisition is approved, the combined company will target revenue of $4.5 billion to $5 billion for its data center solutions business in 2028, according to the release.

Kelvion has previously served customers in AI infrastructure, energy system transformation and energy/ industrial markets. Its past work focuses on heat pumps, renewables, carbon capture and processing solutions for thermal management. According to the news release, Kelvion's data center revenue is expected to reach about $1.2 billion in 2026, and the sector is considered the company’s "largest and fastest-growing end market.

Houston geothermal startup bumps Series B to $180M with Nabors investment

fresh funding

Houston-based geothermal startup Quaise Energy has closed its Series B fundraising round at $180 million after inking a significant investment from another local energy leader.

Quaise, which is developing a 50-megawatt superhot geothermal plant in Oregon, announced a "first close" of the round last month at $134 million, led by San Francisco-based investment firm Prelude Ventures. The $46 million bump has been fueled by a $35 million investment from Houston-based Nabors Industries.

The funding will go toward the continued development of the company's superhot geothermal plant, Project Obsidian, as well as the commercialization of Quaise's millimeter-wave drilling system, according to a news release.

“We are unlocking the most powerful clean energy source on Earth, and the Series B signals deep conviction across a wide range of investors,” Carlos Araque, Quaise CEO and president, said in the release. “Nabors is an invaluable partner as we move millimeter wave drilling to full commercial operations at Project Obsidian and beyond.”

Nabors, a repeat investor in Quaise, has also entered into a strategic framework agreement with Quaise. Under the agreement, Quaise will have access to a dedicated Nabors land rig and drilling platform. Nabors will also provide expertise in reservoir modeling, well design and drilling strategy.

Last year, Quaise drilled to a depth of about 330 feet using its millimeter-wave technology at its field site in Central Texas. Canary Media previously reported that Quaise plans to drill to nearly 3,300 feet later this year and to deploy its millimeter-wave technology at its power plant in 2027. The plant is expected to deliver power to the Pacific Northwest in 2030.

Quaise and Nabors say the partnership will improve drilling performance, reduce costs and accelerate project timelines.

“Superhot geothermal has the potential to make clean energy ubiquitous. That is why we are excited about our close relationship with Quaise,” Anthony Petrello, president and CEO of Nabors, added in the release. “Quaise’s millimeter wave technology changes the equation entirely by reaching superhot rock at temperatures and depths that are inaccessible with conventional drilling, transforming geothermal from a location-dependent resource into a global energy solution. Combined with Nabors’ drilling expertise and infrastructure, we see a path to gigawatt-scale geothermal power that no other company can offer today.”

Quaise reports that with the latest funding, it has now raised $280 million. It raised $21 million in a Series A1 financing round in 2024 and a $52 million Series A in 2022.

The company announced in March that it was aiming to raise $200 million for Project Obsidian through $100 million in Series B funding, plus an additional $100 million from grants, debt and project-level finance.
