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).

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.

top spot

The accolades keep coming for Houston-based geothermal energy company Fervo Energy.

Fervo sits atop Time magazine’s and Statista’s 2026 list of America’s Top GreenTech Companies. Fervo ranked No. 6 on the list last year.

The ranking honors 250 companies in the U.S. based on their environmental impact, innovation and financial strength. Fervo joins five other Houston-area companies on the list.

No. 49 Quaise Energy, an MIT Energy Initiative spinout that’s developing a drilling system designed to convert existing power stations for geothermal power production
No. 71 Plus Power, which develops, owns and operates battery energy storage systems
No. 98 Utility Global, whose technology enables industrial decarbonization
No. 199 Solugen, whose technology converts plant-based feedstocks into carbon-negative chemicals
No. 215 Noodoe, which specializes in EV charging stations and software

Fervo says its approach to enhanced geothermal systems (EGS)—including horizontal drilling, AI-enabled drilling and exploration, advanced reservoir engineering, and fiber-optic sensing—demonstrates how validated technology can help deliver reliable zero-emission power.

“By applying drilling technology from the oil and gas industry, we have proven that we can produce 24/7 carbon-free energy resources in new geographies across the world,” Fervo co-founder and CEO Tim Latimer said last year.

Other recent recognitions for Fervo includes:

The 2025 Houston Innovation Awards named it Scaleup of the Year
MIT Technology Review put Fervo on its 2025 list of the 10 global climatech companies to watch
Time named Fervo one of the 100 Most Influential Companies of 2025
Fervo was hailed as the Global Cleantech Group 100 North American Company of the Year
Fervo was among Congruent Ventures’ and Silicon Valley Bank’s 50 by 2050 companies, all of which are poised to advance global decarbonization over a 25-year span

Just last month, Fervo secured $421 million in debt financing for the construction of its 500-megawatt Cape Station geothermal project in Utah. And in December, the company landed an oversubscribed $462 million Series E round of funding, pushing its valuation to an estimated $1.4 billion. Fervo filed for an IPO earlier this year.

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.

Houston's KBR tapped to provide tech for first SAF plant in Kazakhstan

clean deals

Houston-based engineering and technology firm KBR Inc. has been tapped to provide technology for Kazakhstan's first sustainable aviation fuel (SAF) production plant.

KazMunayGas-Aero LLP (KMG-Aero), a subsidiary of Kazakhstan’s national oil and gas company KazMunayGas, and KazFoodProducts awarded the contract to KBR for the project. The plant will use the alcohol-to-jet (AtJ) process for producing aviation fuel and aims to support President Kassym-Jomart Kemeluly Tokayev’s goal of boosting Kazakhstan's profile as a global aviation player, according to a news release from KBR.

"We are honored to support KMG-Aero and KFP in advancing the national commitment to reduce greenhouse gas emissions, recognizing the pivotal role of aviation decarbonization in achieving these strategic objectives,” Jay Ibrahim, president of KBR Sustainable Technology Solutions, said in the release.

KBR will provide its PureSAF technology and engineering design for the project. Invented and developed by Swedish Biofuels AB, the PureSAF tech will be used to convert alcohol-based feedstocks into SAF. The PureSAF Technology can process multiple feedstocks—like bioethanol, syngas, carbon dioxide and hydrogen—and convert them to SAF, diesel and gasoline, according to KBR.

"KBR’s PureSAF is a feed-flexible, bankable technology that is designed to deliver high SAF yields and supports the project across the full lifecycle,” Ibrahim added in the release. “We look forward to closely collaborating and supporting the successful execution of this landmark SAF project.”

Earlier this summer, KBR was also chosen to provide technology for what’s expected to be Asia's first commercial-scale ethanol-to-jet (SAF) plant. The plant has a planned production capacity of up to 100,000 tons of SAF per year.

In addition to the SAF projects, KBR also announced this month that it has been selected by ORNX Green Hydrogen to provide proprietary ammonia technologies for a low-cost green ammonia project in Morocco.

The commitments come as KBR shifts its focus solely toward sustainability technology and services. The company is in the process of spinning off its Mission Technology Solutions business, which KBR recently announced will be named Trinzic. The remaining company, "New KBR," will serve the ammonia and syngas, chemical and petrochemicals, clean refining and circular economy markets.
