Fervo Energy strikes largest-ever power deal with Google

geothermal milestone

In its largest-ever purchase agreement, Houston-based geothermal company Fervo Energy will supply 396 megawatts of power to tech powerhouse Google.

The deal includes an option for Google to expand capacity by about 600 megawatts, for a total of 1 gigawatt, by June 2030, according to a news release from Fervo. Financial terms weren’t disclosed.

Google will purchase carbon-free energy from Fervo for a potential data center in Utah, where Fervo is building its more than $2 billion Cape Station geothermal project.

Fervo applies oil-and-gas fracking technology to create geothermal reservoirs and generate electricity.

The first phase of Cape Station is expected to begin delivering geothermal power by late 2026, reaching about 100 megawatts of capacity by early 2027. The second phase, set for completion in 2028, will add 400 megawatts of capacity.

Fervo co-founder and CEO Tim Latimer said in a release that the Google agreement supports enhanced geothermal systems as a key power source for “the next generation of computing infrastructure.”

“The next chapter of advanced power generation technology is being written in Utah,” said Lucia Tian, director of advanced energy technologies at Google.

The Fervo-Google agreement builds on an existing partnership. Fervo’s Project Red pilot development in Nevada, which came online in 2023, supplies power to the local grid. Users of the grid power include Google’s data centers in Nevada.

Fervo subsequently signed a 115-megawatt purchase agreement with Google and NV Energy. The deal enabled Google to bring more geothermal energy to the Nevada grid while insulating everyday customers from the project’s costs.

The latest Google deal is part of the ongoing expansion of Cape Station beyond its initial 100-megawatt phase. Fervo says Cape Station will be the world’s largest enhanced geothermal facility.

The Google agreement comes during a milestone year for Fervo, which was founded in 2017. In May, Fervo’s IPO raised $2.2 billion. The company, whose early investors include Bill Gates, is now valued at $5.65 billion.

Fervo Energy, Mercury Fund leaders named first experts in residence for TEX-E

energy mentors

Two leading companies in Houston's clean energy scene have been named the Texas Exchange for Energy & Climate Entrepreneurship's first experts in residence.

TEX-E announced this month that Houston-based geothermal unicorn Fervo Energy and venture capital firm Mercury Fund have joined the nonprofit's new Expert-in-Residence partnership. The program aims to connect TEX-E Fellows with "the people and organizations shaping the future of energy and entrepreneurship."

The 2026 TEX-E Fellows were named in June and include 67 students from six Texas universities and the Massachusetts Institute of Technology. Nineteen are from Houston universities. See the full list here.

Through the Expert-in-Residence program, fellows will be able to network and work with:

"More than anything, students need the determination and creativity to step outside of their comfort zones and tackle problems that lack clear answers. At Fervo, we've consistently bet on young people who lack traditional 'hard skills' but are willing to embrace uncertainty and learn on the job. That open-mindedness will take students far," Jewett said in a prepared statement. Fervo named Jewett as COO in June.

TEX-E was founded in 2022 through partnerships with MIT Martin Trust Center for Entrepreneurship and Greentown Labs. It works with university students from six schools: Rice University, University of Houston, Prairie View A&M University, The University of Texas at Austin, Texas A&M University and MIT.

The organization named Houston venture capital and innovation leader Sandy Guitar as its new executive director last year. Guitar previously served as general partner and managing director at Houston-based VC firm HX Venture Fund and is co-founder of Weathergage Capital.

TEX-E is known for its student track within the Energy Venture Day and Pitch Competition at CERAWeek. It awarded $50,000 to student teams from the University of Texas and Rice University. Read more here.

Experts: Houston's VC ecosystem has set the foundation — now we need scale

guest column

Fervo Energy went public earlier this summer. The Houston geothermal company priced its IPO at $27 per share, raised $1.89 billion, and opened the next morning at a market capitalization north of $10 billion. By most measures, it is the largest venture-backed cleantech IPO in history and an unambiguous win for Houston. It’s also a useful moment to look at where Houston's venture ecosystem stands and where it can go. The highlight: Houston's venture ecosystem has real foundations and, with increased company formation activity, can grow into the scale our city's ambitions deserve.

A Houston energy story in the national recovery

The recent uptick in Houston venture activity follows national trends. U.S. venture deal count contracted roughly 22 percent from its 2021 peak through 2024 before rebounding to about 16,700 rounds in 2025. Houston's 23 percent increase in VC funding from 2023 to 2024 is part of a national recovery of comparable magnitude over the same time window.

The energy sector is where Houston exhibits unique trends—and where the story turns clearly positive. (Houston's strong health and space sectors deserve their own separate consideration.) By deal count, energy-related rounds have accounted for 15 to 20 percent of Houston activity, roughly consistent over the past few years.

By capital, energy's share surged from about 14 percent in 2023 to over 60 percent in 2025, driven by a small number of large Houston-headquartered rounds, primarily in geothermal and related technologies. Fervo is the obvious anchor, but Sage Geosystems, Quaise Energy, Zeta Energy, Vaulted Deep, Applied Carbon and Mariana Minerals have all closed meaningful rounds. Houston is concentrated and accelerating as an energy capital market, an invaluable position to build upon.

From foundation to scale

The institutional pieces are in place. Greentown Labs, Activate, the Ion and others have built sector-specialized infrastructure most cities would struggle to assemble. Fervo itself is an alum of both Activate and Greentown Labs. Mercury Fund closed its $160 million Fund V, its largest ever. Houston Angel Network, GOOSE Capital, Fathom Fund, and broader pre-seed and seed capital coverage are here. The Houston $10 million-plus Series A list now includes 40 rounds since 2021, which break roughly into two eras. While 2021 to 2022 was biotech-heavy, with companies like Sporos Bioventures, RadioMedix, Cellenkos and Coya Therapeutics, 2024 to 2025 has tilted clearly toward energy, climate, and critical minerals, with Vaulted Deep, Applied Carbon, Mariana Minerals, Sage Geosystems and Ignis H2 Energy among them.

What’s less developed is the volume of seed-stage companies flowing into that capital. Imagine a dozen more Fervos coming out of that infrastructure over the next decade, each generating jobs, recycled founder capital, and the next wave of operators and angel investors. That is the kind of opportunity Houston has within reach if we build the company-formation pipeline to feed it. To be relevant on the national stage as a venture market, and to drive an economy the size of Houston's into the 2030s, the city needs to be doing closer to 20 Series A rounds per month rather than per year. That throughput implies roughly 1,000 seed rounds per year, feeding the funnel at a 20 percent to 30 percent graduation rate. Reaching such throughput depends on how many new founders Houston produces and how quickly our innovation ecosystem can help them achieve lift-off.

Houston in context

The comparative picture brings the scaling challenge into focus. Between 2021 and 2024, Houston-area startups closed between 126 and 153 disclosed venture rounds per year, against a national count between 9,854 and 14,125. That places Houston at a little over 1 percent of the U.S. deal count. For comparison, Austin ran about three times Houston's deal count each year.

At the Series A level, Houston closed between 12 and 24 rounds in any given year. The median Houston Series A across the period was about $10.7 million, compared with $15.4 million in San Francisco. Houston founders are raising fewer and smaller Series A rounds than founders in peer metros, which points directly to where Houston has the most room to grow.

The unicorn picture tells the same story. From 2021 through 2025, the U.S. produced 590 venture-backed unicorns. Four were Houston-based: Solugen and Axiom Space in 2021, Cart.com in 2023, and Fervo Energy in 2024. Adding HighRadius from 2020 brings Houston's all-time total to five. Austin added 19 over the same five-year window. The path from here is to make Houston's entries on lists like these less the exception and more the rule.

Where this leads

Houston has a real opportunity to become the deepest, most credible energy and climate capital market in the country, with the company formation, talent and operator density to support it. The data shows the foundation is already in place. Fervo, Solugen and the growing roster of energy-adjacent Series A graduates are proof. Fervo's IPO is the first of what should be many. Houston has not had a venture-backed cleantech liquidity event of this scale before, and the city now has one to reference, recruit against and build on. With increased company formation at the seed and pre-seed stages, a Fervo-scale outcome need not be a generational event in Houston, but instead, it can become part of a chain reaction powering the city's economy.

Houston cleantech startup closes $17M round to tap into hot geothermal sector

fresh funding

Houston-area startup Hephae Energy Technology Corp. has closed a $17.8 million Series A financing round to commercialize its geothermal technology.

The round was co-led by Pennsylvania-based Susquehanna Sustainable Investments, which invests in early-stage climatech companies, and Copenhagen-based Underground Ventures, which focuses on geothermal energy startups. Alfa8, Baruch Future Ventures, Centaurus Capital LP, Elemental Impact, Exa Ventures, Future Ventures, Grantham Foundation for the Protection of the Environment, New System Ventures and True North Institute joined the round, along with existing Houston-based investor Nabors Industries. Hyphae reports in a news release that the Series A round brings the company's total capital raised to $24.7 million.

Hephae develops ultra-high-temperature downhole sensing, measurement, communications and control systems that can withstand the heat of geothermal sites, which are hotter and deeper than traditional oil and gas reservoirs. The company's Pandora210 system can operate at up to 400 degrees Fahrenheit.

Hephae reports that it plans to use the new funding to commercialize its Pandora210 tool and to launch research and development into systems that can withstand temperatures of up to 570 degrees Fahrenheit. Houston-based Fervo Energy, for instance, recently tapped its hottest geothermal well to date in western Utah, showing temperatures above 555 degrees Fahrenheit.

"Commercial deployment represents a major milestone in our mission to scalable, always-on, emission-free power globally, with a world-class team to tackle this problem," Steve Krase, CEO of Hephae Energy Technology, said in the release." This investment enables Hephae to transition from development to scale, delivering the ultra-high temperature drilling technologies needed to support the rapid growth of the geothermal industry in the US and international markets."

Hephae has been collaborating with Fervo Energy in the field. The company told the Houston Business JournalHouston Business Journal this spring that it expected its Pandora210 technology to be deployed at its Utah sites.

“Fervo is encouraged by the early progress of our collaboration with Hephae, whose novel high-temperature innovations have the potential to contribute positively to EGS economics, unlock higher-energy geothermal resources, and further cement the competitiveness of next-generation geothermal power," Elliot Howard, director of drilling and completions at Fervo, added in the release.

As the geothermal industry continues to scale, Hephae says it aims for its technology to help companies "unlock hotter, deeper resources that result in lower produced energy costs."

The Spring-based startup was founded in 2020 by CEO Steve Krase and CTO John Clegg. Krase previously launched Navigate Energy Services, which was acquired by Nabors in 2013. Clegg is also an industry veteran and has held numerous leadership positions at energy companies, including Weatherford, NOV, Schlumberger and others.

Kanin Energy raises up to $100M for waste-heat-to-power projects

fresh funding

Kanin Energy, a member of the Greentown Labs climatech and energy incubator in Houston, recently raised as much as $100 million in capital to grow its energy-as-a-service platform.

S2G Investments led a round of up to $50 million, and the Canada Growth Fund chipped in an additional $50 million. The money will primarily support Kanin’s development and operation of waste-heat-to-power projects.

Kanin—founded in 2020 in Calgary, Alberta, Canada—builds and runs onsite power assets for large-scale energy users. The startup says its energy-as-a-service offering lowers power costs, boosts power reliability and decreases emissions.

The company operates a waste-heat-to-power project at Ohio’s University of Dayton. The project supplies zero-emission electricity.

Kanin has a pipeline of projects totaling about 50 megawatts of capacity. This includes a waste-heat-to-power plant at the Phillips 66 Mewbourn gas-processing plant near Greeley, Colorado.

“Kanin was built on the belief that industrial facilities already hold the solution to their own energy challenges, they just need the right partner to execute,” Janice Tran, CEO of Kanin, who is based in Houston, said in a release. “At a time when power costs continue to rise, [our] solutions are an important tool for our industrial customers to manage their costs, operations, and emissions.”

Marisa Sweeney, principal at S2G, says waste heat is a largely underused resource for lowering power costs, alleviating grid congestion and improving power reliability.

The waste-heat-to-power process captures thermal energy from industrial activities and converts it to electricity. This happens without using extra fuel or generating more emissions.

Kanin says up to 58 percent of energy consumed by industrial processes is lost as waste heat. This heat winds up in the atmosphere at thousands of facilities in North America, including oil-and-gas operations, cement plants, and steel mills, the startup says.

Kanin was founded in 2020 in Calgary, Alberta, Canada. It opened offices at Greentown Labs Houston in July 2022.

7 Houstonians from energy sector make Forbes list of richest Americans

Rich List

The richest billionaires in America have a collective worth of $8 trillion in 2026, a staggering $1.4 trillion increase since last year, says Forbes. American billionaires are so wealthy that it now takes an unprecedented $4.4 billion net worth to be considered one of the richest people in the country. And one local billionaire has regained the title as Houston's wealthiest resident.

The annual Forbes 400 list is a definitive ranking of the wealthiest Americans, using interviews, financial data, and documentation provided by billionaires and their companies. In all, 43 billionaires across Texas made it on the 2026 list, and 10 are based in Houston. Seven of them have ties to the energy industry.

He cofounded Hilcorp, one of the largest privately owned oil and natural gas producers in the U.S., in 1990 and served as its CEO until 2018. He still serves as the chairman of the company.

Kinder Morgan chairman Richard Kinder is the No. 2 richest in Houston. Kinder, 81, was dubbed Houston's richest billionaire in the 2025 Forbes 400 list. His net worth has increased from $11.1 billion to $12.9 billion in just one year. He is the 11th richest Texan and the 100th richest person in America.

Houston pipeline heir Randa Duncan Williams ranks 124th on the list with an estimated net worth of $11.7 billion. Fellow pipeline heirs Dannine Avara and Milane Frantz tie for 128th nationally. Each has an estimated net worth of $11.6 billion. Scott Duncan ties for No. 137 with an $11.3 billion estimated net worth.

Energy exploration chief executive George Bishop of GeoSothern Energy ranks No. 380 with an estimated net worth of $4.5 billion. Last year: $4.7 billion.

Here's how the rest of Houston's billionaires, outside of the energy industry, ranked on this year's list:

  • Toyota mega-dealer Dan Friedkin, 61, is the 102nd richest American with an estimated net worth of $12.9 billion, up from $9.7 billion last year. He most notably owns Gulf States Toyota, which sold $14.5 billion worth of Toyotas in 2025, per Forbes.
  • Hospitality honcho Tilman Fertitta, 69, has a net worth of $12.3 billion and is the 110th richest American. Fertitta owns hospitality corporation Fertitta Entertainment and the NBA team Houston Rockets. He most recently purchased the WNBA's Connecticut Sun and plans to relocate them to Houston under the Houston Comets name in 2027. He also keeps himself busy as President Trump's ambassador to Italy.
  • Texans owner and CEO Cal McNair, 64, ranks as the 218th richest person in America with an estimated net worth of $7.7 billion.
