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.”

Cemvita expands in Brazil with acquisition, new leader

going global

Houston industrial biotech company Cemvita has announced two strategic moves to advance its operations in Brazil.

The company, which utilizes synthetic biology to transform carbon emissions into valuable bio-based chemicals, acquired a complementary technology that expands its IP and execution of scale-up capacity, according to a news release. The acquisition will bring additional synthetic biology toolsets that Cemvita believes will assist with compressing and commercializing timelines.

The company also appointed Luciano Zamberlan as vice president of operations based in Brazil.

Zamberlan will lead operational execution, site readiness and early commissioning activities in Brazil. He brings more than 20 years of experience in biotechnology to the role. He recently served as director of engineering at Raízen, Brazil’s largest ethanol producer and the world’s largest producer of sugarcane ethanol. At Raízen, he coordinated the implementation of four greenfield plants and oversaw operational teams and process optimization for second-generation ethanol (E2G) and biogas.

“I am very pleased to join Cemvita, a company at the forefront of transforming waste into valuable, sustainable resources,” Zamberlan said in the release. “My expertise in scaling-up innovation, coupled with my experience in structuring and commissioning greenfield industrial operations, is perfectly aligned with Cemvita's mission and I'm eager to bring my energy and drive to accelerate Cemvita's industrial performance and contribute for a circular future.”

Cemvita expanded to Brazil in January to help capitalize on the country’s progressive regulatory framework, including Brazil’s Fuel of the Future Law, enacted in 2024. The law mandates an increase in the biodiesel content of diesel fuel, starting from 15 percent in March and increasing to 20 percent by 2030. It also requires the adoption of Sustainable Aviation Fuel (SAF) and for domestic flights to reduce greenhouse gas emissions by 1 percent starting in 2027, growing to 10 percent reduction by 2037.

“These steps enable us to augment Brazil’s longstanding bioindustrial ecosystem with next-generation capabilities, reducing early commercialization risk and expanding optionality for future product platforms,” Marcio Silva, CTO of Cemvita, said in the news release. “Together, they strengthen our ability to move from proof-of-concept to industrial reality.”

Gold H2 harvests clean hydrogen from depleted California reservoirs in first field trial

breakthrough trial

Houston climatech company Gold H2 completed its first field trial that demonstrates subsurface bio-stimulated hydrogen production, which leverages microbiology and existing infrastructure to produce clean hydrogen.

Gold H2 is a spinoff of another Houston biotech company, Cemvita.

“When we compare our tech to the rest of the stack, I think we blow the competition out of the water," Prabhdeep Singh Sekhon, CEO of Gold H2 Sekhon previously told Energy Capital.

The project represented the first-of-its-kind application of Gold H2’s proprietary biotechnology, which generates hydrogen from depleted oil reservoirs, eliminating the need for new drilling, electrolysis or energy-intensive surface facilities. The Woodlands-based ChampionX LLC served as the oilfield services provider, and the trial was conducted in an oilfield in California’s San Joaquin Basin.

According to the company, Gold H2’s technology could yield up to 250 billion kilograms of low-carbon hydrogen, which is estimated to provide enough clean power to Los Angeles for over 50 years and avoid roughly 1 billion metric tons of CO2 equivalent.

“This field trial is tangible proof. We’ve taken a climate liability and turned it into a scalable, low-cost hydrogen solution,” Sekhon said in a news release. “It’s a new blueprint for decarbonization, built for speed, affordability, and global impact.”

Highlights of the trial include:

  • First-ever demonstration of biologically stimulated hydrogen generation at commercial field scale with unprecedented results of 40 percent H2 in the gas stream.
  • Demonstrated how end-of-life oilfield liabilities can be repurposed into hydrogen-producing assets.
  • The trial achieved 400,000 ppm of hydrogen in produced gases, which, according to the company,y is an “unprecedented concentration for a huff-and-puff style operation and a strong indicator of just how robust the process can perform under real-world conditions.”
  • The field trial marked readiness for commercial deployment with targeted hydrogen production costs below $0.50/kg.

“This breakthrough isn’t just a step forward, it’s a leap toward climate impact at scale,” Jillian Evanko, CEO and president at Chart Industries Inc., Gold H2 investor and advisor, added in the release. “By turning depleted oil fields into clean hydrogen generators, Gold H2 has provided a roadmap to produce low-cost, low-carbon energy using the very infrastructure that powered the last century. This changes the game for how the world can decarbonize heavy industry, power grids, and economies, faster and more affordably than we ever thought possible.”

global expansion

Houston biotech company Cemvita has announced a strategic collaboration with Brazilian sustainable research institution REMA.

The move aims to promote Cemvita’s platform for evaluating and testing carbon waste streams as feedstocks for producing sustainable oil, according to the company.

Cemvita utilizes synthetic biology to transform carbon emissions into valuable bio-based chemicals. REMA professors Marcio Schneider and Admir Giachini have previously worked with Cemvita’s CTO, Marcio Busi da Silva, for approximately 20 years.

“This long-standing partnership reflects not only our strong professional ties, but also our shared commitment to advancing science and technology for a more sustainable future," Busi da Silva said in a news release.

REMA’s center is based in Florianópolis and is affiliated with the Federal University of Santa Catarina, which develops cost-effective environmental and technological solutions in automation, chemical engineering, biotech, environmental engineering and agronomy.

“Partnering with REMA in Florianópolis represents a significant step forward in our mission to transform carbon waste into valuable resources,” Tara Karimi, chief science and sustainability officer of Cemvita, said in a news release. “Together, we will enhance our platform’s capabilities, leveraging REMA’s expertise to evaluate and utilize diverse waste streams for sustainable oil production, further advancing the circular bioeconomy in Brazil and beyond.”

Cemvita recently expanded to Brazil to capitalize on the country’s progressive regulatory framework, which includes Brazil’s Fuel of the Future Law. The expansion also aimed to coincide with the 2025 COP30, the UN’s climate change conference, which will be hosted in Brazil in November.

Cemvita became capable of generating 500 barrels per day of sustainable oil from carbon waste at its first commercial plant in 2024, and as a result, Cemvita quadrupled output at its Houston plant. The company originally planned to reach this milestone in 2029.

Also in 2025, Cemvita announced a partnership with Brazil-based Be8 that focused on converting biodiesel byproduct glycerin into low-carbon feedstock to help support the decarbonization of the aviation sector. Cemvita agreed to a 20-year contract that specified it would supply up to 50 million gallons of SAF annually to United Airlines in 2023.

Houston’s power future: The role of energy efficiency and demand response

The View from HETI

In Houston, industrial expansion, advanced manufacturing, data centers, AI, electrification, and population growth are all increasing demand for power across the region. At the same time, the infrastructure needed to support that growth, from generation and transmission to distribution and storage, takes significant time and investment to plan and build.

This growing power demand creates a near-term challenge: how can the region support new investment while major grid projects are planned and built?

A new report from the Houston Energy Transition Initiative, “Role of Efficiency & Demand Response to Meet Near-Term Regional Power Demand”, examines how Houston can get more from the grid it has today. Its central finding: energy efficiency (EE) and demand response (DE) can create measurable grid “headroom” while new major infrastructure projects are being planned, financed, permitted and built.

Explore the key takeaways from the report:

Houston’s power challenge affects economic growth

Houston’s ability to attract industrial investment increasingly depends on reliable, affordable power. ERCOT and MISO Texas project major load growth through 2030 and 2035 from industrial development, data centers, AI, advanced manufacturing and electrification.

Efficiency and demand response can lower peak demand and help manage local grid constraints that could slow growth.

EE and DE are different tools, and Houston needs both

Energy efficiency creates lasting reductions in electricity use through equipment upgrades, building improvements and changes in operations. Demand response lets customers temporarily reduce or shift power use based on grid conditions, incentives or market signals.

Texas programs show measurable results

In 2024, Texas investor-owned utility programs delivered about 609 MW of evaluated demand reduction and 603 GWh of annual energy savings. The report puts the lifetime cost of saved energy at about $0.02 per kWh.
CenterPoint Energy accounted for more than 40% of ERCOT investor-owned utilities’ total demand reduction and energy savings. It achieved about 236 MW of peak demand reduction and 229 GWh of energy savings, above goals of 66 MW and 116 GWh.

Entergy Texas also achieved significantly more demand reduction and energy savings than its 2024 program year goals, with a reported 24 MW of peak demand reduction against a goal of 17 MW and 43 GWh of energy savings against a goal of 30 GWh.

Large power users can add flexibility

Data centers, industrial facilities and advanced manufacturers may be able to shift noncritical work, adjust cooling, use on-site resources or briefly cut consumption.

The report states that verified demand savings, flexible loads and behind-the-meter resilience could help reduce interconnection risk and support more cost-effective growth.

Technology can expand options

Storage, smart controls and energy management systems can work with efficiency and demand response. Smaller loads can also be combined across commercial buildings, multifamily developments and homes.

For Houston, these tools do not replace new generation, transmission, distribution or storage. They can help the region use existing infrastructure more effectively while new capacity is built, supporting reliable, affordable power and continued economic growth.

New 160MW battery storage project comes online in Houston

powered on

Colorado-based energy storage company SMT Energy and North Carolina-based software company FlexGen have begun operations of Houston IV, a 160-megawatt utility-scale battery storage facility that aims to support the ERCOT grid.

The companies delivered the project in just six weeks, according to a news release. Mississippi-based Irby Construction Company served as the engineering, procurement, and construction (EPC) partner, and CenterPoint Energy will serve as the interconnecting utility.

“FlexGen’s distinctive combination of software automation, our remote operations center, and on-the-ground field expertise all work together to accelerate battery deployment,” Jason Rislov, SVP of operations at FlexGen, said in the release. “What used to take 25-plus weeks took us six. That time saved translates directly into giving the grid and consumers what they need most right now: a more reliable, resilient energy system.”

Houston IV is one of more than 12 projects that SMT and FlexGen have built to connect to ERCOT, according to Energy Storage News.

“Bringing a 160-MW battery storage facility online in just six weeks required disciplined planning, seamless coordination, and an unwavering focus on safety and quality,” Shaun Coleman, project manager at Irby Construction, said in a news release. “The SMT Energy, FlexGen, and Irby Construction teams coordinated engineering, procurement, and construction to keep every workstream aligned, identify challenges early, and maintain safety and quality at an accelerated pace. That integration is critical, not only to delivering projects quickly, but also to ensuring battery storage facilities perform reliably over the long term.”

Houston IV is expected to store and provide enough electricity to power 8,800 homes in Texas annually. In March, SMT Energy secured $135 million in funding for the project from Macquarie and KeyBanc Capital Markets as joint lead arrangers. SMT and FlexGen broke ground to signal the start of the process in May.

In 2023, SMT Energy and joint venture partner SUSI Partners also announced plans to add 10 battery storage projects to Texas, which would double capacity from 100 megawatts to 200 megawatts in the Houston and Dallas areas.
