Houston co. enters new carbon capture collaboration focused on biofuels industry

cleaning up

Carbon Clean, a carbon capture company whose North American headquarters is in Houston, has forged a deal with a contractor to build modular carbon capture containers for the agricultural sector.

The company, based in the United Kingdom, says its tentative partnership with Merrill, Wisconsin-based AGRA Industries should speed up adoption of Carbon Clean’s CaptureX technology in the biofuel industry.

Carbon Clean’s technology has been installed at 49 sites around the world. Eighty percent of the sites have prefabricated modular carbon-capture containers, reducing construction and installation time.

The partnership will enable customers to capture CO2 released during the biofuel fermentation stage, enabling the production of fuels with lower carbon-intensity ratings. This will improve the ability of biofuel producers to claim federal tax credits, Carbon Clean says.

“Carbon Clean’s collaboration with AGRA Industries is a win-win for biofuel producers. Customers will benefit from the expertise of a leading agricultural engineering specialist and our modularized, innovative carbon capture technology that is cost-effective and simple to install,” Aniruddha Sharma, chair and CEO of Carbon Clean, says in a news release.

Carbon Clean’s customers include companies in the cement, steel, refinery, and energy-to-waste sectors.

Among the investors in Carbon Clean, founded in 2019, are Chevron, Samsung Ventures, Saudi Aramco Energy Ventures, and WAVE Equity Partners. To date, the company has raised $260 million in funding, according to data platform Tracxn.

ExxonMobil extends European fuel cell pilot project

next step

The Esso fuel business of Spring-based ExxonMobil is forging ahead with a pilot project at its Dutch refinery in Rotterdam to test technology aimed at reducing carbon emissions and simultaneously generating electricity and hydrogen.

ExxonMobil and FuelCell announced the pilot project in 2023.

“The unique advantage of this technology is that it not only captures CO2 but also produces low-carbon power, heat, and hydrogen as co-products,” Geoff Richardson, senior vice president of ExxonMobil Low Carbon Solutions, said last year.

The Rotterdam facility, which opened in 1960, will be the first location in the world to test the technology. The technology eventually could be rolled out at additional ExxonMobil sites.

The European Union is among the funders of the pilot project. FuelCell is making carbonate fuel cells for the project at its manufacturing plant in Torrington, Connecticut.

The extended agreement enables FuelCell to incorporate elements of the jointly developed technology into carbon capture products currently being marketed to customers. ExxonMobil and FuelCell are working on formalizing an arrangement for selling the new technology.

“The technology, which captures carbon while simultaneously generating electricity and hydrogen, could improve the economics of carbon capture and could potentially lower the barrier to broader adoption of carbon capture in the marketplace,” according to a FuelCell news release.

FuelCell says its 10-year partnership with ExxonMobil has focused on developing technology that reduces carbon emissions from emission-intensive sectors while generating electricity and hydrogen in the process — “something that no other fuel cell technology or conventional absorption systems can do.”

Navigating the energy transition is a relay race, and the baton is in Houston, says this energy executive. Photo courtesy of SCS

O&G exec: Houston is where the future of energy is taking shape

Q&A

Earlier this month, a West Texas-based oilfield equipment provider announced that it was opening an office in the Ion Houston. It's all a part of the company's energy transition plan.

SCS Technologies, based in Big Spring, Texas, has a new strategy and innovation-focused office in the Ion, the company announced last week. The company, which provides CO2 capture measurement and methane vapor recovery equipment for the energy, industrial, and environmental sectors, also announced René Vandersalm as the new COO.

These are just the latest moves for the company as the world moves away from hydrocarbons and toward a greener future, CEO Cody Johnson tells EnergyCapital, explaining that he recognizes Houston has a role in the energy transition.

"This is a relay race – a race that has already started," he says. "Houston is the place where the baton will be handed off – it’s the place where the race is occurring. SCS Technologies is determined to be part of this solution dreamed of and planned in Houston and then executed in the Permian Basin, where we call home."

In an interview with EnergyCapital, Johnson weighs in on the new office and the future of his company.

EnergyCapital: How has SCS’s business evolved amid the energy transition?

Cody Johnson: SCS Technologies was founded to design and fabricate customized Lease Automated Custody Transfer units in the Permian Basin. These LACT units were used primarily to measure the quality and quantity of crude oil at all points of custody transfer. Essentially, SCS Technologies produced the premier "crude cash registers" for the Permian Basin.

As the oil and gas industry has adapted into the energy transition industry, our customers and the communities we operate in have a growing need for SCS Technologies to use our design and fabrication of measurement skids to measure the quality and quantity of CO₂ or to design and fabricate methane — and other vent gases — Vapor Recovery Units. SCS Technologies’ design and fabrication expertise in measurement skids, pump skids, and compression skids, coupled with our Permian Basin based training and fabrication campus, ideally positioned us to answer the call to fill the expertise and capacity gap.

EC: How are you preparing for the future of energy?

CJ: Society has been powered for the past 100 years or so by the management of hydrocarbon molecules. The essential tools for that have been and continue to be oil rigs, pipelines, and refineries in large part. This has given society many benefits but at a price to the environment that isn’t sustainable. Over the next 50 years, society will complete a transition away from managing hydrocarbon molecules and towards managing electrons. Those electrons are created by wind, solar, geothermal, or nuclear processes and travel down copper wires. Managing this transition that is already occurring and working together to do it in the near-term future of energy.

As we execute this transition over the next several decades from managing molecules to managing electrons to provide energy, molecule management companies must find ways to reach net zero emissions in their management practices. This means primarily capturing and managing methane vapors and capturing and sequestering CO₂. This is starting in 2023 in a meaningful way and needs to continue past 2030 and probably past 2050 to have any chance to meet the globally shared social goal to achieve net zero emissions by 2050 and stay below a maximum increase of 1.5 degrees C in global temperatures.

The clock is ticking, and we are behind. The largest molecule management infrastructure investment in history must happen for us to reach these goals. It's mission-critical as one of the three things we simply cannot fail at to achieve net zero by 2050. SCS Technologies is very focused on being an intentional part of the tremendous supply chain buildout to support the infrastructure buildout.

EC: How does the new office in the Ion support these plans?

CJ: SCS Technologies needs to collaborate with the brightest minds working on the energy transition challenges. To contribute meaningfully to the overall effort and to be the thought leader in the methane vapor recovery and CO₂ compression and measurement niche, we need to be at the heart of the energy transition collaboration community. That beating heart is the Ion in Houston.

EC: What role does your new COO, René Vandersalm, play in SCS evolving with the energy transition?

CJ: René is a proven executive in growing mission-critical design and fabrication capacity without sacrificing quality. René’s experience, capabilities, and global network will play a key role in our path forward.

EC: Based in West Texas, SCS has a growing presence in Houston. Why do you see Houston as a leader in the energy transition?

CJ: West Texas has an amazing group of oil and gas professionals and infrastructure. We are proud of that heritage and will always maintain our roots and foundation there. Houston has the only community of engineers, scientists, universities, companies, investors, and key professional service providers that can deliver on the buildout of the molecule management infrastructure required to buy the electron management infrastructure folks time to transition fully to green energy after 2050.

This is a relay race – a race that has already started. Houston is the place where the baton will be handed off – it’s the place where the race is occurring. SCS Technologies is determined to be part of this solution dreamed of and planned in Houston and then executed in the Permian Basin, where we call home.

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.

TEX-E was founded in 2022 through partnerships with MIT Martin Trust Center for Entrepreneurship and Greentown Labs. 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.
