Houston-based biotech company Cemvita has achieved a key production goal five years ahead of schedule.

Thanks to technology advancements, Cemvita is now capable of generating 500 barrels per day of sustainable oil from carbon waste at its first commercial plant. As a result, Cemvita has quadrupled output at the Houston plant. The company had planned to reach this milestone in 2029.

Cemvita, founded in 2017, says this achievement paves the way for increased production capacity, improved operational efficiency, and an elevated advantage in the sustainable oil market.

“What’s so amazing about synthetic biology is that humans are just scratching the surface of what’s possible,” says Moji Karimi, co-founder and CEO of Cemvita. “Our focus on the first principles has allowed us to design and create new biotech more cheaply and faster than ever before.”

The production achievement follows Cemvita’s recent breakthrough in development of a solvent-free extraction bioprocess.

In 2023, United Airlines agreed to buy up to one billion gallons of sustainable aviation fuel from Cemvita’s first full-scale plant over the course of 20 years.

Cemvita’s investors include the UAV Sustainable Flight Fund, an investment arm of Chicago-based United; Oxy Low Carbon Ventures, an investment arm of Houston-based energy company Occidental Petroleum; and Japanese equipment and machinery manufacturer Mitsubishi Heavy Industries.

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.”

3 takeaways from COP28 from Houston biotech, sustainability founder

big picture

Before he even had a chance to recover from the jetlag, Moji Karimi was thinking about his biggest takeaways from 2023 United Nations Climate Change Conference or Conference of the Parties, more commonly known as COP28.

Karimi, CEO and co-founder of Cemvita, a biotech company with sustainable solutions for the energy transition, joined the Houston Innovators Podcast this week to discuss what his biggest takeaways were.

"It was a pretty amazing experience," Karimi says, comparing the event to how CERAWeek has evolved to really have a strong presence in its innovation-focused track called Agora. "This year you had a massive section for innovation and sustainability. I think that will become a theme in COP29 and beyond to bring entrepreneurs, investors, and more participating in the event."

Karimi's three big observations are outlined below, as is the full podcast with him sharing more about Cemvita's growth this year.


Expanding the environmental footprint

One of the big things Karimi observed was that there seems to be a rising conversation about not only how carbon emissions are effecting climate change, but that companies and countries need to look more broadly at their environmental impacts.

Specifically, Karimi learned about the new framework Task Force on Nature-Related Financial Disclosures (TNFD), an addition to Task Force on Climate-Related Financial Disclosures (TCFD), which was introduced a few years back.

"TNFD is the new framework to capture non-carbon emissions-related aspects of an impact on the environment, such as biodiversity loss," he says.

Language has evolved to reflect this shift too, Karimi says, referencing "nature-positive tech" and "nature tech." He says he feels like Europe has led the way so far, but in the next year or two the conversations will come to the United States.

"Some of this is driven by COP30 being in Brazil and being focused on biodiversity," he adds.

A major focus on nuclear

Karimi says he saw a lot of support for nuclear energy, which can lower the cost and carbon intensity of power. Personally, Karimi is wondering what happens if and win nuclear is better adapted, solving the current challenges the power industries face.

"What I'm interested in is so many other climate tech applications that are enabled once you have low-cost, and low-carbon power from nuclear energy. That will be interesting to watch," he says.

Actionism, not activism

Lastly, Karimi says he saw a huge push toward action, not simply advocacy. The emphasis on "actionism" included activations for COP28 attendees to share what actions could be taken now.

"The point was to all come together, no matter where you come from, and focus on what actions you can take," he says. "It was interesting to bring people together in a different way. We'll see how that translates into actions from here on."

Sustainable biotech company to test hydrogen production technology with global chemicals leader

seeing gold

Two Houston-area companies have announced a strategic partnership to test a unique hydrogen production technology.

The Woodlands-based ChampionX Corporation (NASDAQ: CHX) and Gold H2 Inc. entered into the partnership on November 9. GH2, a subsidiary of Houston-based Cemvita, provides tailored subsurface microbiology solutions by harnessing the power of microorganisms to enable in-situ hydrogen production from depleted oil and gas wells.

Created with carbon neutrality, the gold hydrogen costs less to create and is more sustainable than its alternatives. Cemvita, a sustainability-focused biotech company, has already seen success from its technology. After successfully completing a pilot test of gold hydrogen in the oil-rich Permian Basin of West Texas, Cemvita raised an undisclosed amount of funding through its Gold H2 spin-out.

ChampionX, a global equipment and services provider for the oil and gas industry, has a suite of services and chemical technologies for optimizing production for reservoirs.

"Could not have asked for a better partner than ChampionX, Victor Keasler and Deric Bryant to helps us bring the Gold H2 technology to life. They are the industry leader in oilfield chemistry and microbiology and we are beyond excited to have them as a collaborator," Cemvita Co-founder and CEO Moji Karimi writes in a LinkedIn post. "I talk about creating a natural resource company of the future and our work at Gold H2 is a perfect example. To learn from subsurface biology and effectively turn the reservoir into a natural bioreactor and proactively biomanufacture end products of interest, integrating upstream with downstream."

Cemvita has had a flurry of corporate partnership announcements this year. In September, the company announced a 20-year off-take agreement with United to provide up to 50 million gallons of sustainable aviation fuel a year across 20 years.

TEX-E names Houston VC leader as new executive director

new hire

The Texas Exchange for Energy & Climate Entrepreneurship (TEX-E) has named Houston venture capital and innovation leader Sandy Guitar as its new executive director.

Guitar succeeds David Pruner, who will move into the board chair role.

Guitar previously served as general partner and managing director at Houston-based VC firm HX Venture Fund and is co-founder of Weathergage Capital. She also sits on the advisory board of Rice University's Liu Idea Lab for Innovation and Entrepreneurship (Lilie) and launched the Women Investing in VC in Houston group.

In a LinkedIn post, Guitar shared that she's looking forward to bringing her problem-solving skills to the energy transition.

"Innovating in the energy sector is as significant and intricate a problem as I have ever worked on — one that demands creativity, collaboration, and resourcefulness at every turn," she shared.

"I'm honored to join TEX-E at such a pivotal time in the energy transition," she added in a news release. "Energy and climate innovation is accelerating at the intersection of brilliant minds and bold ideas. I'm excited to help TEX-E amplify that collision between students who think differently and the real-world problems that demand fresh solutions."

According to TEX-E, Guitar will continue to lead the organization's programming that aims to connect student climate entrepreneurs with "industry reality."

"Sandy understands the complexities of the Texas energy ecosystem and brings a forward-looking vision for how related innovation can drive meaningful, lasting impact. She's exactly the leader we need to take TEX-E to the next level and help create the next generation of energy transition innovators," David Baldwin, TEX-E board member, added in the release.

It works with university students from six schools: Rice University, University of Houston, Prairie View A&M University, The University of Texas at Austin, Texas A&M University and MIT.

It's known for its student track within the Energy Venture Day and Pitch Competition at CERAWeek, which awarded $25,000 to HEXASpec, a Rice University-led team, at the 2025 event. It also hosted its inaugural TEX-E Conference, centered on the theme of Energy & Entrepreneurship: Navigating the Future of Climate Tech, earlier this year.

Expert: Debunking the myth that Texas doesn't care about renewable energy

Guest Column

When most people think about Texas, wind turbines and solar panels may not be the first images that come to mind. But in reality, the state now leads the nation in both wind-powered electricity generation and utility-scale solar capacity. In 2024 alone, Texas added approximately 9,700 megawatts of solar and 4,374 megawatts of battery storage, outpacing all other energy sources in new generation capacity that year. So what’s driving Texas’ rapid rise as the renewable energy capital of the United States?

Leader in wind energy

Texas has been a national leader in wind energy for more than a decade, thanks to its vast open landscapes and consistent wind conditions, particularly in regions like West Texas and the Panhandle. These ideal geographic features have enabled the development of massive wind farms, giving Texas the largest installed wind capacity in the United States. Wind energy also plays a strategic role in balancing the grid and complements solar energy well, as it often peaks at night when solar output drops.

Battery storage growth

Increasing battery storage capacity is unlocking more potential from solar and wind. When intermittent energy sources like wind and solar go offline, batteries release stored electricity and provide stability to the Electric Reliability Council of Texas system. Excluding California, Texas has more battery storage than the rest of the United States combined, accounting for over 32% of all the capacity installed nationwide.

Solar electricity generation and utility-scale batteries within ERCOT power grid set records in summer 2024. Between June 1 and August 31, solar contributed nearly 25% of total power demand during mid-day hours. In the evening, as demand stayed high but solar output declined, battery discharges successfully filled the gap. Battery storage solutions are now a core element of ERCOT’s future capacity and demand planning.

Interest in creating a hydrogen economy

Texas is well positioned to become a national hub in the hydrogen economy. The state has everything needed to lead in this emerging space with low-cost natural gas, abundant and growing low carbon electricity, geology well suited for hydrogen and carbon storage, mature hydrogen demand centers, existing hydrogen pipelines, established port infrastructure and more. The state already has an existing hydrogen market with two-thirds of the country’s hydrogen transport infrastructure.

In 2023, the Texas Legislature created the Texas Hydrogen Production Policy Council, which found that:

  • Hydrogen could represent a grid-scale energy storage solution that can help support the increased development of renewable electricity from wind and solar. Renewable electricity that is converted to hydrogen can improve overall grid reliability, resilience and dispatchability.
  • The development of the hydrogen industry, along with its supporting infrastructure and its downstream markets within Texas, could attract billions of dollars of investment. This development may create hundreds of thousands of jobs - especially with younger generations who are passionate about climate science - and greatly boost the Texas economy.
  • Hydrogen supports the current energy economy in Texas as a critical component to both conventional refining and the growing production of new biofuels (such as renewable diesel and sustainable aviation fuel) within the state.

Legislative action and pressure to reduce carbon emissions

Texas has also seen key legislative actions and policies that have supported the growth of renewable energy in Texas. During the most recent legislative session, lawmakers decided that The Texas Energy Fund, a low-interest loan program aimed at encouraging companies to build more power infrastructure, will receive an additional $5 billion on top of the $5 billion lawmakers approved in 2023. Of that amount, $1.8 billion is earmarked to strengthen existing backup generators, which must be powered by a combination of solar, battery storage and natural gas. These funds signal growing institutional support for a diversified and more resilient energy grid.

Furthermore, there is growing pressure from investors, regulators and consumers to reduce carbon emissions, and as a result, private equity firms in the oil and gas sector are diversifying their portfolios to include wind, solar, battery storage and carbon capture projects. In 2022, private equity investment in renewable energy and clean technology surged to a record-high $26 billion.

The future of the renewable energy workforce

With renewable energy jobs projected to grow to 38 million globally by 2030, the sector is poised to be one of the most promising career landscapes of the future. Given that young people today are increasingly environmentally conscious, there is a powerful opportunity to engage students early and help them see how their values align with meaningful, purpose-driven careers in clean energy. Organizations like the Energy Education Foundation play a vital role in this effort by providing accessible, high-quality resources that bridge the gap between energy literacy and real-world impact. The nonprofit employs comprehensive, science-based educational initiatives to help students and educators explore complex energy topics through clear explanations and engaging learning tools, laying a strong foundation for informed, future-ready learners.

STEM and AI education, which are reshaping how young people think, build, and solve problems, provide a natural gateway into the renewable energy field. From robotics and coding to climate modeling and sustainable engineering, these learning experiences equip students with the critical skills and mindsets needed to thrive in a rapidly evolving energy economy. By investing in engaging, future-focused learning environments now and through leveraging trusted educational partners, like the Energy Education Foundation, we can help ensure that the next generation of learners are not just prepared to enter the clean energy workforce but are empowered to lead it.

With its rapidly growing wind, solar, battery and hydrogen sectors, Texas is redefining its energy identity. To sustain this momentum, the state must continue aligning education, policy, and innovation—not only to meet the energy demands of tomorrow, but to inspire and equip the next generation to lead the way toward a more sustainable, resilient and inclusive energy future.
