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-area company leads Texas businesses on Time's most sustainable list

Spring-based IT company Hewlett Packard Enterprise leads the list of eight Texas businesses that appear in Time magazine’s and data provider Statista’s World’s Most Sustainable Companies list for 2025.

HPE landed at No. 68, earning a score of 74.36 out of 100.

Time and Statista said the ranking highlights corporate responsibility and promotes sustainable practices.

“In an era marked by significant environmental challenges and social inequalities, it is crucial to recognize and reward companies prioritizing sustainability,” according to an article on Time’s website. “By featuring these leading entities, the ranking sets a benchmark for other businesses, fostering transparency and accountability and encouraging the integration of sustainability into core corporate strategies.”

Time and Statista’s ranking process started with a list of more than 5,000 of the world’s largest, most influential companies based on factors such as revenue and public prominence. They identified the top 500 companies based on more than 20 data points.

The process weeded out non-sustainable businesses, such as those involved in producing fossil fuels, and zeroed in on:

  • External sustainability ratings
  • Availability and quality of sustainability reports
  • Performance regarding environmental and social responsibility measures

HPE is targeting net-zero status across its supply chain by 2040. Working toward that goal, the company predicts its carbon emissions will decrease by 33 percent from 2020 to 2028.

“The climate transition demands collective action across our entire value chain, and I am resolute in my commitment to ensure that HPE plays a central role in showcasing the attainability of net-zero emissions through our technologies and actions,” said Antonio Neri, HPE’s president and CEO.

ENGIE strikes clean energy deal with Houston biomanufacturer

energy match

ENGIE North America has signed an agreement with Aker BioMarine to supply around-the-clock, Texas-sourced clean energy to the Norwegian company's Houston manufacturing facility.

The deal is through ENGIE's 24/7 offering, which allows users to "match electricity consumption with local renewable generation on an hourly basis," rather than annual renewable energy matching, according to a news release.

Houston-based ENGIE NA will match 90% of Aker BioMarine's hourly electricity consumption at its Houston facility through renewable energy certificates that link electricity consumed to clean power generated. The renewable energy will be sourced largely from ENGIE's Impact Solar Project in Lamar County, Texas.

“Working with companies that have made sustainability a core part of their strategy is essential to delivering meaningful progress,” Taymur Bunkheila, regional VP and retail supply lead for ENGIE’s U.S. 24/7 product, said in the release. “By aligning energy solutions with operational needs, we can help organizations improve transparency, strengthen accountability, and deliver measurable outcomes. This agreement demonstrates how companies can take practical steps today while building toward long-term sustainability objectives.”

Aker BioMarine, which develops sustainable marine-based ingredients, processes the majority of its krill and algae products at its Houston facility. The company says the deal with ENGIE marks an important step in reducing the environmental footprint of its operations.

“Through this agreement, we expect to reduce our Scope 2 emissions, marking an important milestone in our broader sustainability journey,” Matts Johansen, CEO at Aker BioMarine, added in the release. “ENGIE has delivered an affordable, innovative and transparent solution that allows us to match our electricity consumption for our Houston manufacturing facility with renewable power generation. The transparent data ENGIE provides strengthens our climate reporting while helping us continue delivering high-quality products with a lower environmental footprint."

ENGIE has more than 11 gigawatts of renewable energy projects in operation or under construction in the U.S. and Canada. The company is targeting 95 gigawatts by 2030

ExxonMobil announces date to move legal headquarters to Texas

save the date

Energy giant Exxon Mobil Corp. has set a date to move its legal headquarters to Texas.

The Spring-based company announced this week that the redomiciliation from New Jersey to Texas is expected to be effective July 1. Exxon's board of directors unanimously recommended redomiciling in the Lone Star State in March, and shareholders approved the move to Texas at the company’s annual meeting in May.

As part of the move, ExxonMobil Holdings Corp. will replace Exxon Mobil Corp. of New Jersey and become the publicly traded parent company. Exxon reports that its shares will continue to trade on the New York Stock Exchange under the ticker symbol “XOM,” and that shareholders do not need to take action.

At the time of the recommendation, Exxon said the move would not affect business operations, management, strategy, assets or employee locations.

Exxon Chairman and CEO Darren Woods added that the redomiciliation was in part due to Texas' business-friendly environment and policies.

"Over the past several years, Texas has made a noticeable effort to embrace the business community. In doing so, it has created a policy and regulatory environment that can allow the company to maximize shareholder value,” Woods said in a news release. "Aligning our legal home with our operating home, in a state that understands our business and has a stake in the company’s success, is important.”

The Associated Press reports that about 30 percent of Exxon's employees work in Texas. Exxon's legal headquarters has been based in New Jersey since 1882, when it was Standard Oil Company.

Exxon moved its operational headquarters from Irving, Texas, to the Houston area in 2023.

Exxon was the highest-ranking Houston-area company on this year's Fortune 500 list, coming in at No. 9. Houston tied with Chicago for the second-most Fortune 500 headquarters on this year's list, with Texas leading the nation for the most Fortune 500 headquarters (57).

“Texas is the undisputed headquarters of headquarters,” Gov. Greg Abbott said in a news release. “The world’s leading businesses invest with confidence in Texas because of our welcoming business climate, predictable regulatory environment, and skilled and growing workforce. People and businesses are choosing Texas because Texas works.”

Houston startups named to World Economic Forum cohort for carbon removal, clean technologies

top honor

Two Houston-based startups have been selected to join the World Economic Forum's Technology Pioneers community.

The two-year program aims to help mission-driven, early-stage start-ups scale their innovations through multi-stakeholder initiatives, co-creating partnerships and other gatherings for community members. One-hundred startups are selected each year from around the globe, this year hailing from 23 countries and working in AI, energy, space, biotech markets and more.

Cleantech startup Vaulted Deep was one of 11 energy and climate companies to be named to the cohort. Julia Reichelstein and Omar Abou-Sayed founded the company in 2023. Its technology injects excess organic waste underground to remove carbon dioxide from the atmosphere.

Last year, Vaulted Deep inked a 12-year deal with Microsoft to remove up to 4.9 million metric tons of carbon dioxide from the environment.

The startup has earned several accolades in recent years, including a No. 3 spot on Fast Company’s list of the World’s Most Innovative Companies of 2026. It was also recently named to market intelligence and advisory firm Cleantech Group's annual Global Cleantech 100 list for a second year in a row.

"Waste management is one of the world's great invisible infrastructure systems ... The need for new infrastructure is growing as disposal challenges become more complex and regulations evolve. Vaulted is building the first new disposal pathway for organic waste in decades by putting it deep underground, permanently," the company shared in a LinkedIn post. "This year, we're joining the World Economic Forum's 2026 Tech Pioneers alongside innovators working on the many interconnected challenges shaping our future."

Houston-based Venus Aerospace was also selected to join the cohort, along with six other spacetech companies. The company was founded in 2020 by Sassie and Andrew Duggleby.

The startup specializes in next-generation rocket engine propulsion as a cleaner alternative to traditional combustion engines. The company's rotating detonation rocket engine (RDRE) burns fuel more efficiently and completed a successful high-thrust test flight last year. Venus says it’s the only company in the world that makes a flight-proven, high-thrust RDRE with a “clear path to scaled production.”

"Frontier technologies matter most when they expand what people, industries, and nations can do," Sassie Duggleby, co-founder and CEO of Venus, said in a news release. "For Venus, RDRE does not just represent a more efficient engine. It is a foundation for faster movement, more capable space systems, and new forms of connectivity across the planet. Being named a Technology Pioneer validates the potential of this technology to help shape a future where distance is less limiting."
