Houston carbon storage solutions company names new energy transition leader at pivotal time of growth

ready to grow

Graham Payne sees a bright future for the multibillion-dollar energy transition economy in Houston.

“It’s been said that Houston is poised, like no other city, to lead the energy transition. And I’d have to agree, because we have all the requisite natural resources, industry, and talent,” says Payne, the new director of energy transition at Houston-based carbon capture, utilization, and storage (CCUS) company Caliche Development Partners II.

Caliche and other Houston-based energy transition companies secured $6.1 billion in private funding last year, up 62 percent from 2022, according to the Greater Houston Partnership.

“As the region positions itself as the leader in the global energy transition, Houston has seen constant growth in annual energy transition investments over the last five years,” the partnership says.

Payne, a geologist, comes to Caliche after holding roles at Battelle and Schlumberger, among other companies. Houston-based Sudduth Search recruited Payne for the Caliche job.

In his new position, Payne is overseeing permitting and completion of a leased 4,000-acre site in Beaumont for sequestration of carbon dioxide. Payne will also work on current and potential gas storage projects, which he says “will continue to play an important role in the energy mix.”

At previous employers, Payne has tackled various aspects of CCUS.

“The really enticing part about this job is the chance to put it all together, and then operate a full-scale operation,” he says. “I want this technology to move firmly out of the research phase and start making a measurable difference against climate change.”

Payne says Caliche is capable of successfully straddling the worlds of CCUS, natural gas storage, and industrial gas storage. The Beaumont project alone will be able sequester at least 30 million metric tons of carbon, a Caliche estimate indicates.

In November, Caliche announced the acquisition of its first CCUS assets, Golden Triangle Storage and Central Valley Gas Storage, following a $268 million infusion of capital from Orion Infrastructure Capital and GCM Grosvenor. Orion maintains offices in Houston, New York City, and London. GCM is based in Chicago.

The Golden Triangle and Central Valley deals were valued at a combined $186 million.

Houston students take home top prizes at DOE wind energy competition

wind winners

The student-led Rice Wind Energy team clinched second place overall at the U.S. Department of Energy’s 2025 Collegiate Wind Competition (CWC), which challenges students nationwide to design and build wind turbines, develop wind energy projects and engage in public outreach to promote renewable energy.

“The Collegiate Wind Competition is such an incredible opportunity for students passionate about sustainability to gain industry-applicable, hands-on experience in the renewable energy space,” senior and team vice president Jason Yang said in a news release.

The event was hosted by the National Renewable Energy Laboratories at the University of Colorado Boulder campus. Over 40 teams entered the competition, with just 12 advancing to the final stage. The competition comprises four core contests: connection creation, turbine design, turbine testing and project development.

Rice Wind Energy had the largest team with 26 students advancing to the final stage of the competition. It picked up a first-place win in the connection creation contest, and also placed third in the project development, fourth in turbine testing and fifth in turbine design contests.

“This accomplishment is a testament to our focus, teamwork and unwavering determination,” senior Esther Fahel, Rice Wind Energy’s 2024-25 president, said in a news release. “It’s a remarkable experience to have watched this team progress from its inception to the competition podium. The passion and drive of Rice students is so palpable.”

In the Connection Creation contest, the team hosted a wind energy panel with Texas Tech University, invited local high school students to campus for educational activities, produced a series of Instagram reels to address wind energy misconceptions and launched its first website.

The team also developed an autonomous wind turbine and floating foundation design that successfully produced over 20 watts of power in the wind tunnel. They were also one of just a few teams to complete the rigorous safety test, which brought their turbine to below 10 percent of its operational speed within 10 seconds of pressing an emergency stop button. It also designed a 450-megawatt floating wind farm located 38 kilometers off the coast of Oregon by using a multi-decision criteria matrix to select the optimal site, and conducted technical modeling.

“I am amazed at the team’s growth in impact and collaboration over the past year,” senior Ava Garrelts, the team’s Connection Creation lead for 2024-25, said in a news release. “It has been incredible to see our members develop their confidence by building tangible skills and lifelong connections. We are all honored to receive recognition for our work, but the entire experience has been just as rewarding.”

Rice faculty and industry sponsors included David Trevas and faculty advisers Gary Woods and Jose Moreto, Knape Associates, Hartzell Air Movement, NextEra Analytics, RWE Clean Energy, H&H Business Development and GE Vernova, Rice’s Oshman Engineering Design Kitchen, George R. Brown School of Engineering and Computing, Rice Engineering Alumni and Rice Center for Engineering Leadership.

The BYU Wind Energy Team took home the overall first-place prize. A team from the University of Texas at Dallas was the only other Texas-based team to make the 12-team finals.

Houston biotech company continues to expand in Brazil with new research partner

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.
