The accolades keep rolling in for Houston-based Fervo Energy, a producer of geothermal power.

Fervo lands at No. 6 on Time magazine and Statista’s new list of America’s Top GreenTech Companies of 2025. The ranking recognizes sustainability-focused companies based on factors such as impact, financial strength, and innovation.

Time notes that Fervo broke ground in 2023 in Utah on what the company claims will be the world’s largest geothermal plant. The plant is scheduled to start supplying carbon-free electricity to the grid next year and to reach its 400-megawatt capacity in three years.

“Technologies like this only make a difference if we deploy them at large-scale in a way that can reduce carbon emissions and increase the reliability of the grid,” Fervo CEO Tim Latimer told Time in 2023.

The startup was named North American Company of the Year by research and consulting firm Cleantech Group for 2025. Fervo topped the Global Cleantech 100, Cleantech Group’s annual list of the world’s most innovative and promising cleantech companies.

Last year, Fervo also made Time’s list of the 200 Best Inventions of 2024. Fervo was recognized in the green energy category for its FervoFlex geothermal power system.

Founded in 2017, Fervo is now a unicorn, meaning its valuation as a private company exceeds $1 billion. The startup’s valuation is estimated at $1.4 billion. According to PitchBook data, the company raised $634 million in the fourth quarter of 2024.

In all, eight Houston-area companies appear among the top 250 greentech companies ranked by Time and Statista. Other than Fervo, they are:

  • No. 43 Lancium Technologies, an energy storage and distribution company
  • No. 50 Solugen, a producer of sustainable chemicals.
  • No. 56 Quaise Energy, which specializes in terawatt-scale geothermal power.
  • No. 129 Plus Power, a developer, owner and operator of battery storage projects.
  • No. 218 Dream Harvest, which promotes sustainable vertical farming.
  • No. 225 Cemvita, which uses synthetic biology to convert carbon emissions into bio-based chemicals.
  • No. 226 Syzygy Plasmonics, which decarbonizes chemical production.
Vermont-based BETA Technologies claimed the No. 1 spot. The company manufactures electric aircraft.

National agency announces $100M in funding for energy advancement at Houston event

seeing green

Rice University played host to the first-of-its-kind event from the Department of Energy’s Advanced Research Projects Agency-Energy, or ARPA-E, earlier this month in which the governmental agency announced $100 million in funding for its SCALEUP program.

Dubbed “ARPA-E on the Road: Houston,” the event welcomed more than 100 energy innovators to the Hudspeth Auditorium in Rice’s Anderson-Clarke Center on June 8. Evelyn Wang, director of ARPA-E, announced the funding, which represents the third installment from the agency for its program SCALEUP, or Seeding Critical Advances for Leading Energy technologies with Untapped Potential, which supports the commercialization of clean energy technology.

The funding is awarded to previous ARPA-E awardees with a "viable road to market" and "ability to attract private sector investments," according to a statement from the Department of Energy. Previous funding was granted in 2019 and 2021.

"ARPA-E’s SCALEUP program has successfully demonstrated what can happen when technical experts are empowered with the commercialization support to develop a strong pathway to market” Wang said. “I’m excited that we are building on the success of this effort with the third installment of SCALEUP, and I look forward to what the third cohort of teams accomplish.”

Rice Vice President for Research Ramamoorthy Ramesh also spoke at the event on how Rice is working to make Houston a leader in energy innovation. Joe Zhou, CEO of Houston-based Quidnet Energy, also spoke on a panel about how ARPA-E funding benefited his company along with Oregon-based Onboard Dynamics’s CEO Rita Hansen and Massachusetts-based Quaise Energy’s CEO Carlos Araque.

Attendees were able to ask questions to Wang and ARPA-E program directors about the agency’s funding approach and other topics at the event.

Houston energy innovators have benefited from programs like SCALEUP.

Quidnet Energy received $10 million in funding from ARPA-E as part of its SCALEUP program in 2022. The company's technology can store renewable energy for long periods of time in large quantities.

In January, Houston-based Zeta Energy also announced that it has secured funding from ARPA-E. The $4 million in funding came from the agency's Electric Vehicles for American Low-Carbon Living, or EVs4ALL, program. Zeta Energy is known for its lithium sulfur batteries

Oxy subsidiary granted landmark EPA permits for carbon capture facility

making progress

Houston’s Occidental Petroleum Corp., or Oxy, and its subsidiary 1PointFive announced that the U.S Environmental Protection Agency approved its Class VI permits to sequester carbon dioxide captured from its STRATOS Direct Air Capture (DAC) facility near Odessa. These are the first such permits issued for a DAC project, according to a news release.

The $1.3 billion STRATOS project, which 1PointFive is developing through a joint venture with investment manager BlackRock, is designed to capture up to 500,000 metric tons of CO2 annually and is expected to begin commercial operations this year. DAC technology pulls CO2 from the air at any location, not just where carbon dioxide is emitted. Major companies, such as Microsoft and AT&T, have secured carbon removal credit agreements through the project.

The permits are issued under the Safe Drinking Water Act's Underground Injection Control program. The captured CO2 will be stored in geologic formations more than a mile underground, meeting the EPA’s review standards.

“This is a significant milestone for the company as we are continuing to develop vital infrastructure that will help the United States achieve energy security,” Vicki Hollub, Oxy president and CEO, said in a news release.“The permits are a catalyst to unlock value from carbon dioxide and advance Direct Air Capture technology as a solution to help organizations address their emissions or produce vital resources and fuels.”

Additionally, Oxy and 1PointFive announced the signing of a 25-year offtake agreement for 2.3 million metric tons of CO2 per year from CF Industries’ upcoming Bluepoint low-carbon ammonia facility in Ascension Parish, Louisiana.

The captured CO2 will be transported to and stored at 1PointFive’s Pelican Sequestration Hub, which is currently under development. Eventually, 1PointFive’s Pelican hub in Louisiana will include infrastructure to safely and economically sequester industrial emissions in underground geologic formations, similar to the STRATOS project.

“CF Industries’ and its partners' confidence in our Pelican Sequestration Hub is a validation of our expertise managing carbon dioxide and how we collaborate with industrial organizations to become their commercial sequestration partner,” Jeff Alvarez, President of 1PointFive Sequestration, said in a news release.

1PointFive is storing up to 20 million tons of CO2 per year, according to the company.

“By working together, we can unlock the potential of American manufacturing and energy production, while advancing industries that deliver high-quality jobs and economic growth,” Alvarez said in a news release.

Houston energy-focused AI platform raises $5M in Mercury-led seed round

fresh funding

Houston-based Collide, a provider of generative artificial intelligence for the energy sector, has raised $5 million in seed funding led by Houston’s Mercury Fund.

Other investors in the seed round include Bryan Sheffield, founder of Austin-based Parsley Energy, which was acquired by Dallas-based Pioneer Natural Resources in 2021; Billy Quinn, founder and managing partner of Dallas-based private equity firm Pearl Energy Investments; and David Albin, co-founder and former managing partner of Dallas-based private equity firm NGP Capital Partners.

“(Collide) co-founders Collin McLelland and Chuck Yates bring a unique understanding of the oil and gas industry,” Blair Garrou, managing partner at Mercury, said in a news release. “Their backgrounds, combined with Collide’s proprietary knowledge base, create a significant and strategic moat for the platform.”

Collide, founded in 2022, says the funding will enable the company to accelerate the development of its GenAI platform. GenAI creates digital content such as images, videos, text, and music.

Originally launched by Houston media organization Digital Wildcatters as “a professional network and digital community for technical discussions and knowledge sharing,” the company says it will now shift its focus to rolling out its enterprise-level, AI-enabled solution.

Collide explains that its platform gathers and synthesizes data from trusted sources to deliver industry insights for oil and gas professionals. Unlike platforms such as OpenAI, Perplexity, and Microsoft Copilot, Collide’s platform “uniquely accesses a comprehensive, industry-specific knowledge base, including technical papers, internal processes, and a curated Q&A database tailored to energy professionals,” the company said.

Collide says its approximately 6,000 platform users span 122 countries.

CenterPoint reports progress on grid improvements ahead of 2025 hurricane season

grid resilience

As part of an ongoing process to make Houston better prepared for climate disasters, CenterPoint Energy announced its latest progress update on the second phase of the Greater Houston Resiliency Initiative (GHRI).

CenterPoint reported that it has completed 70 percent of its resiliency work and all GHRI-related actions are expected to be complete before the official start of the 2025 hurricane season.

"Our entire CenterPoint Houston Electric team is focused on completing this historic suite of grid resiliency actions before the start of hurricane season,” Darin Carroll, Senior Vice President of CenterPoint's Electric Business, said in a news release. “That is our goal, and we will achieve it. To date, we have made significant progress as part of this historic effort.”

CenterPoint’s resiliency solutions include clearing higher-risk vegetation across thousands of miles of power lines, adding thousands more automation devices capable of self-healing, installing thousands of storm-resistant poles, and undergrounding hundreds of miles of power lines.

CenterPoint's GHRI efforts, which entered a second phase in September 2024, aim to improve overall grid resiliency and reliability and are estimated to reduce outages for customers by more than 125 million minutes annually, according to the company. It has undergrounded nearly 350 miles of power lines, about 85 percent of the way toward its target of 400 miles, which will help improve resiliency and reduce the risk of outages. CenterPoint also aims to install the first of 100 new local weather monitoring stations by June 1.

In March, CenterPoint cleared 655 miles of high-risk vegetation near power lines, installed 1,215 automated reliability devices capable of self-healing, and added an additional 3,300 storm-resilient poles.

In April, CenterPoint will begin building a network of 100 new weather monitoring stations, which will provide 24/7 weather monitoring and storm response preparation.

“We will continue to work every day to complete these critical improvements as part of our company's goal of building the most resilient coastal grid in the country,” Carroll added in the release.
