A carbon innovation initiative in collaboration with Greentown Houston has named its new cohort.

The Carbon to Value Initiative (C2V Initiative) — a collaboration between NYU Tandon School of Engineering's Urban Future Lab (UFL), Greentown Labs, and Fraunhofer USA — has named nine startup participants for the fourth year of its carbontech accelerator program.

"Once again, the C2V Initiative has been able to select some of the most promising carbontech startups through a very competitive process with a 7 percent acceptance rate," Frederic Clerc, director of the C2V Initiative and interim managing director of UFL, says in a news release. "The diversity of this cohort, in its technologies, products, geographies, and stages, makes it an amazing snapshot of the rapidly evolving carbontech innovation landscape."

The cohort was selected from over a hundred applications from nearly 30 countries. In the six-month program, the nine companies gain access to the C2V Initiative's Carbontech Leadership Council, an invitation-only group of corporate, nonprofit, and government leaders who provide commercialization opportunities and identify avenues for technology validation, testing, and demonstration.

The year four cohort, according to the release, includes:

  • Ardent, from New Castle, Delaware, is a process technology company that is developing membrane-based solutions for point-source carbon capture and other chemical separations.
  • CarbonBlue, from Haifa, Israel, develops a chemical process that mineralizes and extracts CO2 from water, which then reabsorbs more atmospheric CO2.
  • MacroCycle, from Somerville, Massachusetts, develops a chemical recycling process to turn polyethylene terephthalate (PET) and polyester-fiber waste into "virgin-grade" plastics.
  • Maple Materials, from Richmond, California, develops an electrolysis process to convert CO2 into graphite and oxygen.
  • Oxylus Energy, from New Haven, Connecticut, develops a direct electrochemical process to convert CO2 into fuels and chemical feedstocks, such as methanol.
  • Phlair, from Munich, Germany, develops a renewable-energy-powered Direct Air Capture (DAC) system using an electrochemical process for acid and base generation.
  • Secant Fuel, from Montreal, Quebec, Canada, develops a one-step electrocatalytic process that converts flue gas into syngas.
  • RenewCO2, from Somerset, New Jersey, is developing an electrochemical process to convert CO2 into fuels and chemicals, such as sustainable aviation fuel (SAF) or propylene glycol.
  • Seabound, from London, England, builds carbon-capture equipment for new and existing ships.

"The depth and breadth of carbontech innovations represented in this applicant pool speaks volumes to this growing and dynamic industry around the world," adds Kevin Dutt, Interim CEO of Greentown Labs. "We're eager to support these nine impressive companies as they progress through this program and look forward to seeing how they engage with the CLC now and into the future."

The C2V Initiative will host a public Year 4 kickoff event on Sept. 19 at Greentown Houston and via livestream.

Hardtech innovator fellowship opens applications for 2025 Houston cohort

submit now

Applications are officially open for a hardtech-focused incubation and fellowship program's second Houston cohort.

Activate's application is live from now through October 23, and all founders of early-stage, research-backed hardtech companies in Houston are encouraged to apply. The Berkley, California-based program launched in Houston last year and recently named its inaugural Houston cohort.

“The Activate Fellowship provides an opportunity for approximately 50 scientists and engineers annually to transform into entrepreneurial leaders, derisk their technologies, define first markets, build teams, and secure follow-on funding,” says Activate’s executive managing director, Aimee Rose, in a news release. “With an average 30 percent annual growth in applications since 2015, we know there is high demand for what we do, and we’re excited to see the talent and impactful ideas that come through the pipeline this year.

The program, led locally by Houston Managing Director Jeremy Pitts, has 249 current Activate fellows and alumni that have collectively raised over $2.4 billion in public and private funding since the organization was founded in 2015.

“The success of Activate Fellows is ample evidence that scientists and engineers have the talent and drive to face global challenges head-on,” adds Activate chief fellowship officer, Brenna Teigler. “Our diverse fellows are transforming technical breakthroughs into businesses across the United States in 26 states across a range of sectors spanning carbon management, semiconductors, manufacturing, energy, chemicals, ocean tech, and more.”

The application is available online, and fellows will be selected in April of next year. The 2025 program will begin in June.

Activate is looking for local and regional early-stage founders — who have raised less than $2 million in funding — who are working on high-impact technology. Each cohort consists of 10 fellows that join the program for two years. The fellows receive a living stipend, connections from Activate's robust network of mentors, and access to a curriculum specific to the program.

Hardtech-focused accelerator program opens applications for inaugural Houston cohort

apply now

As of today, Houston innovators can apply for a new-to-Houston program that supports researchers on their entrepreneurial journeys.

Coinciding with Climate Week NYC Activate opened application period for its 2024 cohort. Applications close October 17.

“Climate Week is a premier showcase for innovation, and the opening of Activate applications couldn’t come at a more aligned time,” Activate Executive Managing Director Aimee Rose says in a news release. “It’s the perfect moment for innovators to connect, plan, and gain momentum when they’re most inspired. We’re poised and ready to support the next wave of brilliant scientists driving real change."

Applications are open across Activate's five programs. The two-year, hardtech-focused program was founded in Berkeley, California, in 2015 and expanded to Boston and New York before launching its virtual program, Activate Anywhere. Activate announced its expansion into Houston earlier this year, naming Jeremy Pitts as Houston managing director.

“Activate’s recruitment process is crucial, as it centers around finding scientists directly interested in solving urgent problems,” Pitts says. “Activate fellows are turning their technical breakthroughs into businesses that can help industries like manufacturing, energy, chemicals, computing, and agriculture, to meet their decarbonization and resiliency goals.”

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).

Houston-based Syzygy lands global customer for first commercial SAF plant

clean fuel deal

Houston-based Syzygy Plasmonics has secured a major future customer for its sustainable aviation fuel.

Syzygy announced this week that it has entered into a capacity reservation agreement with World Fuel Services, a global fuel distribution and logistics company.

Through the deal, World Fuel has reserved a portion of Syzygy's SAF production for future plants slated for Central and South America. The clean fuel will be produced at Syzygy’s NovaSAF-1 facility in Uruguay, which is moving toward construction.

The NovaSAF-1 will be the world's first electrified facility to convert biogas into sustainable aviation fuel (SAF). The facility is expected to produce over 350,000 gallons of SAF annually, which would be considered “a breakthrough in cost-effective, scalable clean fuel,” according to Syzygy.

The facility is expected to produce SAF with at least an 80 percent reduction in carbon intensity compared to Jet A fuel and make its first deliveries in 2028.

"Following NovaSAF-1, this agreement reflects continued interest in scalable pathways for producing SAF from biogas," Trevor Best, CEO of Syzygy Plasmonics, said in a news release. "Our NovaSAF platform is designed to deliver cost-competitive fuel while supporting the aviation sector's evolving regulatory and sustainability requirements."

Syzygy will make a portion of future production capacity available to World Fuel from its planned facilities, subject to the development and completion of those projects, according to the deal.

"We continue to evaluate supply opportunities that support increased access to lower carbon fuels in aviation, in line with emerging regulatory requirements and customer demand," Michael Ranger, senior vice president of supply EMEAA at World Fuel, added in the release. "Arrangements such as this are part of our ongoing efforts across the supply chain.”

Syzygy also secured an offtake agreement with Singapore-based commodity company Trafigura from NovaSAF-1 earlier this year.

Texas Gov. Abbott seeks data center crackdown as state grapples with growing power demand

growing pains

Just seven months ago, Gov. Greg Abbott trumpeted Google’s $40 billion plan to add three data center campuses in Texas. Now, amid growing public outcry over such projects, Abbott is pushing for a regulatory crackdown on data centers in the Lone Star State.

Abbott recently sent a letter to leaders of the Public Utility Commission of Texas (PUC) and the Electric Reliability Council of Texas (ERCOT) proposing stricter oversight of the state’s data centers. Texas is home to more than 400 data centers, with many more on the way, and is poised to become the world’s largest data center market.

Among other things, Abbott wants to:

  • Ensure residential electric bills go down — not up — as data centers connect to ERCOT’s grid, which supplies power for about 90 percent of Texans.
  • Require data centers to cover the costs of upgrades to deliver electricity to the power-hungry facilities.
  • Repeal sales tax exemptions and other “outdated or unnecessary” financial incentives for data centers.
  • Institute “best practices,” such as property setbacks and noise-reduction technology, to ease the impact of data centers on nearby residents.
  • Demand that all new data centers, which use a tremendous amount of water, be built with water-efficient technology.
  • Require large data centers to generate annual reports on their use of electricity and water.

Abbott has set a July 17 deadline for the PUC and ERCOT to address his recommendations.

“As Texas continues to welcome innovation and investment, we must ensure that growth strengthens our people and their quality of life without placing undue burdens on Texans and local communities,” Abbott wrote.

Abbott’s call for tighter control of data centers has elicited both praise and skepticism.

In a social media post on X, Texas House Speaker Dustin Burrows, a Lubbock Republican, thanked Abbott for seeking “accountability and reform” in the state’s data center industry. Burrows has made data centers one of his priority issues for the 2027 state legislative session.

State oil and gas regulator Wayne Christian, a member of the Texas Railroad Commission, weighed in with similarly positive comments about Abbott’s directive. He says an outright ban on data centers isn’t the answer to residents’ complaints about new facilities.

“The Texas way is not to answer innovation with government overreach or fear-driven bans,” Christian, whose agency wasn’t cited in Abbott’s letter, said in a statement posted on X. “Our job is to protect prosperity, safeguard taxpayers and ensure the infrastructure that powers our economy remains strong and reliable.”

Gina Hinojosa, an Austin Democrat who’s challenging Abbott in this November’s gubernatorial race, took issue with the governor’s edict on data centers.

“Greg Abbott is changing his tune on data centers because he knows his policies are unpopular,” Hinojosa, a state representative, wrote on X. “Nobody believes the arsonist is gonna be the one to put out the fire.”

Abbott’s call for stepped-up regulation of data centers echoes many of the concerns expressed by the state chapter of the Sierra Club, an environmental nonprofit.

“The growth of data centers reflects a broader transformation taking place across Texas,” the Sierra Club says on its website. “The state is becoming a hub for the technologies that will shape the future economy, from artificial intelligence to advanced computing and cloud services. At the same time, Texans deserve transparency about how these projects affect the communities where they are built.”
