Houston-based biotech company Cemvita announced that it recently reached a critical milestone in the development of its FermOil product, which can be used to create Sustainable Aviation Fuel (SAF) and other renewable fuels at industrial scale.

The company shared in a news release that it completed a 75,000-liter industrial fermentation run at Belgium's Bio Base Europe Pilot Plant.

The campaign achieved target technical metrics for the production of FermOil, Cemvita’s renewable natural oil (RNO). FermOil is produced from industrial crude glycerin, an industrial byproduct, as opposed to traditional sugar-based feedstocks used in many bio-oil fermentation processes. It's designed to be a drop-in feedstock for creating SAFs.

Cemvita had previously advanced its FermOil production process through multiple scale-up stages before successfully reaching the 75,000-liter demonstration campaign, according to the company.

“This is not just a fermentation milestone,” Moji Karimi, CEO at Cemvita, said in the release. “It is a blueprint for how existing industrial infrastructure can evolve into circular bioeconomy infrastructure. Every biodiesel plant generating crude glycerin is a potential platform for renewable natural oil production.”

The milestone also supports the deployment of Cemvita’s industrial biomanufacturing platform, FermWorks, which integrates with existing energy and industrial infrastructure to turn waste carbon streams into SAFs and other materials. According to the release, Cemvita plans to move forward with commercial deployment discussions with partners in Brazil, Europe and in the UK. Cemvita already has a partnership with the Brazilian sustainable research institution REMA.

“We are proud to support innovative companies like Cemvita in scaling breakthrough industrial biotechnology solutions,” Hendrik Waegeman, head of business operations at Bio Base Europe Pilot Plant, added in the release. “Successfully operating at the 75,000-liter scale using a feedstock such as crude glycerin highlights both the maturity of the technology and the quality of the scale-up execution achieved by the Cemvita team.”

Energy industry veteran named CEO of Houston hydrogen co.

GOOD AS GOLD

Cleantech startup Gold H2, a spinout of Houston-based energy biotech company Cemvita, has named oil and gas industry veteran Prabhdeep Singh Sekhon as its CEO.

Sekhon previously held roles at companies such as NextEra Energy Resources and Hess. Most recently, he was a leader on NextEra’s strategy and business development team.

Gold H2 uses microbes to convert oil and gas in old, uneconomical wells into clean hydrogen. The approach to generating clean hydrogen is part of a multibillion-dollar market.

Gold H2 spun out of Cemvita last year with Moji Karimi, co-founder of Cemvita, leading the transition. Gold H2 spun out after successfully piloting its microbial hydrogen technology, producing hydrogen below 80 cents per kilogram.

The Gold H2 venture had been a business unit within Cemvita.

“I was drawn to Gold H2 because of its innovative mission to support the U.S. economy in this historical energy transition,” Sekhon says in a news release. “Over the last few years, my team [at NextEra] was heavily focused on the commercialization of clean hydrogen. When I came across Gold H2, it was clear that it was superior to each of its counterparts in both cost and [carbon intensity].”

Gold H2 explains that oil and gas companies have wrestled for decades with what to do with exhausted oil fields. With Gold H2’s first-of-its-kind biotechnology, these companies can find productive uses for oil wells by producing clean hydrogen at a low cost, the startup says.

“There is so much opportunity ahead of Gold H2 as the first company to use microbes in the subsurface to create a clean energy source,” Sekhon says. “Driving this dynamic industry change to empower clean hydrogen fuel production will be extremely rewarding.”

Rice University spinouts named among 50 top cleantech companies to watch

green team

Two Rice University spinouts, Coflux Purification and DexMat, appear on a new list of the world’s 50 cleantech companies to watch.

Cleantech Group’s 2026 Cleantech 50 to Watch list recognizes early-stage companies “creating groundbreaking solutions to address some of the world’s most pressing environmental and sustainability challenges.”

Cleantech Group, a market research, consulting, and events company, selects the 50 honorees based on insights from analysts and early-stage innovators, along with public nominations.

Destroying “forever chemicals”

Coflux, founded in 2024, offers an onsite treatment system that captures and destroys manufactured “forever chemicals”—per- and polyfluoroalkyl substances—in water and wastewater. It’s a member of Greentown Houston.

Alec Ajnsztajn, CEO; Jeremy Daum, chief technology officer; and Dana Vazquez, chief commercial officer, co-founded Coflux. Ajnsztajn and Daum earned doctoral degrees from Rice, and Vazquez earned an MBA from the university.

Coflux spun out of Rice labs directed by professors Rafael Verduzco and Pulickel Ajayan.

Last year, Coflux received a $175,000 grant from the U.S. Food and Drug Administration’s National Institute of Food and Agriculture. The startup has also raised more than $500,000 in non-dilutive funding, including $80,000 awarded in 2024 by Rice’s One Small Step Grant program.

Promoting an alternative to copper

DexMat, founded in 2015, produces carbon nanotube products such as fibers, yarns, cables, and fabric. The company’s products address demand for materials that can reduce carbon emissions, according to CB Insights.

Its main product, Galvorn, is a copper alternative made of carbon nanotube fibers. CB Insights says Galvorn is engineered to be lighter and stronger than traditional conductive materials like carbon and steel. It’s used in industries such as energy, aerospace, defense, automotive, consumer electronics, and health care.

DexMat emerged from Matteo Pasquali’s Carbon Lab at Rice. Pasquali, co-founder of DexMat, co-invented the company’s technology with the late Nobel Prize-winning chemist Rick Smalley. Smalley was a professor of chemistry, physics, and astronomy at Rice.

Pasquali is a professor of chemical and biomolecular engineering, chemistry, materials science, and nanoengineering at Rice. He co-founded DexMat with Rice graduate Dmitri Tsentalovich, the company’s director of product innovation.

Earlier this year, DexMat raised $5 million in seed funding from Non Sibi Ventures, Governance Partners, Tailwind Futures, BetterWay, Capital Factory, and other investors. The company also secured $3 million in non-dilutive funding.

In 2023, DexMat raised $3 million in a pre-seed round led by Shell Ventures.

TotalEnergies expands solar joint venture with $1.2B portfolio in Texas, Ohio

solar expansion

TotalEnergies, a French company whose U.S. headquarters is in Houston, announced this month that it is expanding its renewable energy joint venture with New York-based investment firm KKR by adding 700 megawatts of utility-scale solar projects.

The deal will add three utility-scale solar assets in Texas and Ohio, which are expected to reach commercial operation by Q1 2027, according to a news release from the company. The portfolio is valued at $1.2 billion.

The 50/50 joint venture between TotalEnergies and KKR currently holds 1.4 gigawatts of renewable energy and will grow to 2.1 gigawatts.

The new deal is expected to close this year. Once completed, TotalEnergies will operate the assets. The electricity generated from the solar projects will be sold to third parties, the company reports.

The companies originally formed the joint venture about a year ago when TotalEnergies sold KKR a 50 percent stake in a North American solar portfolio valued at $1.25 billion. The deal originally included six utility-scale solar assets, primarily located in the U.S.

“TotalEnergies is a renewable energy industry leader globally, and we are thrilled to establish this joint venture with the TotalEnergies team to support their renewables business," Cecilio Velasco, managing director KKR, said in a release last year. “We have long been investors in renewables through our infrastructure platform, having committed more than $23 billion to date in energy transition investments. TotalEnergies’ North American solar portfolio is a great fit for us, representing high-quality renewable energy assets with long term contracts.”

TotalEnergies reports that by June 2026 it held more than 37 gigawatts of gross renewable power generation capacity. It aims to achieve over 100 terawatt-hours of net electricity production by 2030.

The company signed a major power purchase agreement with Google earlier this year. Through the deal, TotalEnergies will supply the tech giant with 1 gigawatt of solar power for its data centers in Texas over a 15-year span.

However, the company also recently redirected nearly $1 billion in capital away from wind energy projects and "decided to renounce offshore wind development in the United States." Read more here.
