6 Houston companies earn recognition on Time’s global greentech list 2026

green giants

Six Houston-area businesses appear on Time magazine’s 2026 list of the world’s top greentech companies, with a high-flying name leading the pack.

The highest-ranked local company is Houston-based geothermal power producer Fervo Energy, which claims the No. 4 spot—up from No. 14 last year.

In May, Fervo raised nearly $1.9 billion in its IPO, making it the biggest-ever IPO in the clean energy sector. The company’s valuation now exceeds $10 billion.

Founded in 2017, Fervo borrows methods from the oil and gas sector to drill wells that go down vertically into hot rock before turning horizontal, letting water circulate through them and produce electricity from the heat it absorbs. Cape Station in Utah, the company's first utility-scale project, is set to start delivering power to the grid later this year, with capacity expected to grow to 100 megawatts by 2027.

Co-founder and CEO Tim Latimer tells Fast Company, which named him a 2026 Visionary of the Year, that he launched his career as a drilling engineer for fossil fuels, “but quickly became obsessed with this idea that the drilling techniques we were using would actually be transformative for the world of geothermal as well.”

Fast Company notes the geothermal power generated by Cape Station will be available 24/7, unlike wind and solar power.

“When you start adding something to the grid mix that’s affordable and works around the clock,” Latimer says, “that’s going to be a huge asset to meeting our country’s energy needs.”

Time teamed up with data provider Statista to compile the second annual ranking of the 250 top greentech companies in the world. Companies on the list either develop or provide green technology, products, or services that help ease or reverse the environmental impacts of human activity.

Statista gathered and analyzed data from more than 8,300 companies to create the list, and they were scored in three categories: positive environmental impact, innovation, and financial strength. Fervo earned a score of 94.63 out of 100.

Joining Fervo on this year’s list are:

  • Houston-based Quaise Energy (No. 78), which specializes in terawatt-scale geothermal power
  • The Woodlands-based Plus Power (No. 112), which develops, owns and operates battery storage projects
  • Houston-based Utility Global (No. 167), which develops decarbonization technology
  • Houston-based 1PointFive (No. 217), an Occidental Petroleum subsidiary that offers large-scale carbon removal and storage.
  • Houston-based Sage Geosystems (No. 250), which produces commercial-scale geothermal power

Earlier this year, six Houston-area companies landed on Time's list of top greentech companies in America: Fervo (No. 1), Quaise Energy (No. 49), Plus Power (No. 71), Utility Global (No. 98), Solugen (No. 199) and Noodoe (No. 215).

Fervo promotes strategy leader to COO as flagship geothermal project nears launch

new leader

Houston geothermal unicorn Fervo Energy has named Sarah Jewett as its new COO.

Jewett steps into the role as the company prepares for its flagship Cape Station geothermal project to deliver its first power later this year.

Jewett joined Fervo in 2020 as director of strategy and most recently served as the company's senior vice president of strategy. She spoke with HETI on the potential of geothermal energy in 2024.

Before Fervo, Jewett served as senior director of corporate development for Houston-based Select Energy Services. She ran hydraulic fracturing crews for Schlumberger in the Permian Basin and Alaska's North Slope early in her career.

In the COO role, Jewett is tasked with creating "the centralized infrastructure required to execute on what the company believes is the most significant commercial opportunity for clean, firm power in history," according to a company release.

“What Sarah has built over the last six years has been foundational to the company’s success. From the time she joined, she has brought an unwavering people-first mindset and outstanding dedication to building things that last,” Tim Latimer, CEO and co-founder of Fervo, added in the release. “As we move into the next phase of our growth, there is no better person to lead the operating core of this company.”

Jewett holds an MBA from Harvard Business School and a bachelor's degree in mechanical engineering from Dartmouth College.

Fervo announced the addition of four heavyweights to its board of directors this spring, including Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE. Shortly after, the company filed for its highly anticipated $1 billion-plus IPO. Read more here.

Houston trio lands on Time’s list of 10 most influential energy companies

making an impact

Three companies with headquarters in Houston made Time magazine’s new list of the 10 most influential energy companies.

The unranked list includes:

  • Houston-based oil and gas giant Chevron
  • Houston-based Fervo Energy, a geothermal power provider that just went public in a $1.9 billion IPO
  • Saudi Aramco, the world’s largest oil company, whose U.S. headquarters is in Houston

In naming Chevron to the list, Time cites the company’s standing as the only major American oil company operating in Venezuela. Time says Chevron wields “extraordinary power” over Venezuela’s massive oil reserves.

Despite pressure from the White House on U.S. oil and gas producers to ramp up investments in Venezuela, “Chevron has pumped the brakes, pledging to boost output gradually and not chase price fluctuations,” Time says.

“Chevron has been in Venezuela for over a century,” CEO Mike Wirth told shareholders in January. “We remain committed to leveraging our deep expertise and long-standing partnerships for the benefit of our shareholders and the people of Venezuela.”

Time points out that Fervo sits “at the front of the pack” in generation of geothermal energy. The Houston-based company uses fracking techniques borrowed from the oil and gas industry to create underground hot-rock reservoirs that heat water to generate electricity.

Fervo’s Cape Station in Utah is scheduled to start delivering power to the grid this year. At full capacity of 500 megawatts, it will be the first large-scale commercial geothermal plant in the U.S. Time says another site in Utah, Project Blanford, is Fervo’s hottest well yet, highlighting the potential for harnessing geothermal heat for at-scale clean energy.

“It’s hard to find something that can [deliver] reliable 24/7 energy, that’s carbon-free, and can be constructed in a timely manner,” Fervo CEO Tim Latimer said. “It’s energy without a lot of the compromises.”

Government-owned Saudi Aramco, which last year earned $104.7 billion in profit, not only is a dominant player in the Mideast oil and gas sector, but Time says it holds “global clout in politics and business” that reaches far beyond oilfields. For example, the company finances big projects spearheaded by Crown Prince Mohammad Bin Salman, who chairs Saudi Arabia’s sovereign wealth fund. These include initiatives in global sports, tourism, and AI.

Fervo Energy officially files for initial public offering

going public

Fervo Energy has officially filed for IPO.

The Houston-based geothermal unicorn filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission on April 17 to list its Class A common stock on the Nasdaq exchange. Fervo intends to be listed under the ticker symbol "FRVO."

The number and price of the shares have not yet been determined, according to a news release from Fervo. J.P. Morgan, BofA Securities, RBC Capital Markets and Barclays are leading the offering.

The highly anticipated filing comes as Fervo readies its flagship Cape Station geothermal project to deliver its first power later this year

"Today, miles-long lines for gasoline have been replaced by lines for electricity. Tech companies compete for megawatts to claim AI market share. Manufacturers jockey for power to strengthen American industry. Utilities demand clean, firm electricity to stabilize the grid," Fervo CEO Tim Latimer shared in the filing. "Fervo is prepared to serve all of these customers. Not with complex, idiosyncratic projects but with a simplified, standardized product capable of delivering around-the-clock, carbon-free power using proven oil and gas technology."

Fervo has been preparing to file for IPO for months. Axios Pro first reported that the company "quietly" filed for an IPO in January and estimated it would be valued between $2 billion and $3 billion.

Fervo also closed $421 million in non-recourse debt financing for the first phase of Cape Station last month and raised a $462 million Series E in December. The company also announced the addition of four heavyweights to its board of directors last week, including Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE.

Fervo reported a net loss of $70.5 million for the 2025 fiscal year in the S-1 filing and a loss of $41.1 million in 2024.

Tracxn.com estimates that Fervo has raised $1.12 billion over 12 funding rounds. The company was founded in 2017 by Latimer and CTO Jack Norbeck.

Fervo Energy adds former eBay CEO Meg Whitman, other leaders to board

power players

As it prepares for a highly anticipated IPO, Houston-based geothermal power provider Fervo Energy has added four heavyweights to its board of directors.

The most notable new board member is Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE, and former U.S. ambassador to Kenya. She joined the Fervo board as lead independent director.

One of the other high-profile new board members at Fervo is Jessica Uhl. She was chief financial officer of Shell from 2017 to 2022 and spent a little over a year as president of GE Vernova, a GE energy spinoff. She is a former board member of GE, Goldman Sachs and Shell. Today, Uhl advises investment firms on energy matters.

Another energy industry veteran, Trey Lowe, also joined the Fervo board. Lowe is senior vice president and chief technology officer at oil and gas producer Devon Energy, a Fervo investor that’s moving its headquarters from Oklahoma City to Houston. Before Devon, Lowe worked in the U.S. and Norway for Houston-based energy technology company SLB.

The fourth new director at Fervo is Robert Keehan, who spent 37 years at professional services firm PwC. He most recently was PwC’s chief global auditor and earlier was a partner in the firm’s energy practice.

Keehan and Uhl will serve as independent directors, which are non-executive governance and oversight roles, while Lowe is a non-independent director, which is a more hands-on role.

With the four new directors, Fervo has seven board members.

The arrival of the four new board members comes at a monumental time for Fervo, a provider of utility-scale geothermal energy:

“Energy markets are demanding dependable, carbon-free power at an unprecedented scale, and Fervo is uniquely positioned to supply it,” Tim Latimer, co-founder and CEO of Fervo, said in December.

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.

Texas City ammonia plant acquired by Yara in $1.3 billion deal

Ammonia Acquisition

Yara North America, a subsidiary of Norwegian fertilizer and ammonia producer Yara International, has agreed to buy an ammonia production plant in Texas City for $1.3 billion.

The seller is GCA Holdings, an affiliate of Texas City-based chemical manufacturer Gulf Coast Ammonia, which is owned by private equity firms Lotus Infrastructure Partners and MB Energy.

The Texas City plant, with an eventual annual capacity of 1.3 million metric tons, is expected to start full production by the end of this year. Yara says the ammonia produced by the plant will serve its own fertilizer production system and its key customers.

During a recent call with analysts and investors, Magnus Ankarstrand, executive vice president and CFO of Yara International, said the plant holds the potential to become one of the company’s most profitable plants. The $1.3 billion purchase price, he added, “is a very attractive entry ticket to ammonia production in the U.S. at a very attractive cost.”

The Texas City plant will add to Yara’s holdings in the Lone Star State, as Yara is the majority owner of an ammonia, hydrogen and nitrogen production plant in Freeport.

Construction of the ammonia plant began in 2020, but technical and infrastructure issues delayed the project. On its website, Gulf Coast Ammonia says the plant represented a $600 million investment.

“Gulf Coast Ammonia is a world-class asset that required disciplined execution across development, financing, construction, and commercial structuring,” Philipp Pletka, managing director of Lotus Infrastructure Partners, says in a news release.

Trexlertown, Pennsylvania-based Air Products, which owns and operates the country’s largest hydrogen pipeline network, will continue to supply hydrogen and nitrogen for the plant under a long-term deal with Yara, according to the release.

However, the news comes two days after Yara International announced that it would no longer be purchasing ammonia assets in the Louisiana Clean Energy Complex (LCEC) from Air Products. In a separate release, Yara said it planned to reallocate funds toward "alternative mature U.S. ammonia investment opportunities with more competitive returns."
