Houston-based climate tech venture firm Ecosphere Ventures has partnered with Virginia Venture Partners and Virginia Innovation Partnership Corporation’s venture capital program to invest in Virginia-based NearStar Fusion Inc., which develops fusion energy power plants.

NearStar aims to use its proprietary plasma railgun technology to safely and affordably power baseload electricity on and off the power grid through a Magnetized Target Impact Fusion (MTIF) approach, according to a news release from the company.

NearStar’s power plants are designed to retrofit traditional fossil fuel power plants and are expected to serve heavy industry, data centers and military installations.

“Our design is well-suited to retrofit coal-burning power plants and reuse existing infrastructure such as balance of plant and grid connectivity, but I’m also excited about leveraging the existing workforce because you won’t need PhDs in plasma physics to work in our power plant,” Amit Singh, CEO of NearStar Fusion, said in a news release.

NearStar will also conduct experiments at the Texas A&M Hypervelocity Impact Laboratory (HVIL) in Bryan, Texas, on prototype fuel targets and evolving fuel capsule design. The company plans to publish the results of the experiments along with a concept paper this year. NearStar will work with The University of Alabama in Huntsville (UAH) to develop computer performance models for target implosions.

NearStar’s MTIF approach will utilize deuterium, which is a common isotope of hydrogen found in water. The process does not use tritium, which NearStar believes will save customers money.

“While avoiding tritium in our power plant design reduces scientific gain of the fusion process, we believe the vastly reduced system complexity and cost savings of eliminating complicated supply chains, regulatory oversight, and breeding of tritium allows NearStar to operate power plants more profitably and serve more customers worldwide, ”Douglas Witherspoon, NearStar founder and chief scientist, said in a news release.

Houston’s Ecosphere Ventures invests in climate tech and sustainability innovations from pre-seed to late-seed stages in the U.S. Ecosphere also supports first-time entrepreneurs and technical founders.

wind deal

Houston-based renewable energy company ENGIE North America has made a deal to supply up to 568 megawatts of renewable electricity for tech giant Oracle's projects in Texas.

The power will come from ENGIE’s wind resources serving the Electric Reliability Council of Texas (ERCOT) grid. Oracle is developing data centers in Abilene and Shackelford, Texas, according to its website.

The Oracle deal is part of ENGIE’s efforts to bring substantial new electricity supply to the grid. In the past six years, ENGIE has developed 12 gigawatts of new renewable generation and battery storage capacity in North Americas, equaling $11 billion in capital, according to the company.

"Our customers are looking for reliable, scalable energy solutions that can support long-term growth," Anne-Laure Chassanite, interim CEO of ENGIE North America, said in a news release. "ENGIE has invested heavily in developing new generation resources across North America, and we're pleased to support Oracle as it continues to expand its operations in Texas. These agreements reflect the strength of our portfolio and our ability to deliver customized energy solutions that help customers meet their business objectives.”

Computer technology and cloud computing company Oracle is working towards its goal to match 100 percent of AI data center electricity use with carbon-free electricity by 2035.

"Oracle is taking a responsible approach to meeting the energy needs of our growing AI and cloud operations in Texas — investing in carbon-free electricity without shifting costs to consumers," Julia Robin, head of infrastructure planning and sourcing for Oracle Cloud Infrastructure, added in the release. "Our agreements with ENGIE advance Oracle's goal to match 100 percent of our AI data center electricity use with carbon-free electricity by 2035, while supporting long-term economic growth with no cost impact to the state of Texas.”

ENGIE also recently won the 2026 Green Power Leadership Award in the Market Innovation category for its work advancing 24/7 renewable energy solutions. The awards honor individuals and companies advancing sustainability and renewables in the energy industry through innovation and leadership.

The company has inked major deals to supply renewable energy to other major companies like Meta, Daikin and others.

Houston energy and innovation leaders come together at Argonne National Laboratory

The view from heti

Nearly 20 companies from Houston, ranging from global multinationals to innovative startups, joined the team at Argonne National Laboratory in Lemont, Illinois, for a full day of meetings, discussions, and networking focused on advancing innovation, commercialization, and industry collaboration.

The fly-in organized by the Houston Energy Transition Initiative, provided a unique opportunity for companies to engage directly with Argonne researchers, technical experts, and leadership while gaining a deeper understanding of the laboratory’s world-class capabilities. Participants explored how national laboratories can help bridge the gap between breakthrough research and commercial deployment, particularly in areas critical to U.S. competitiveness and economic growth.

The significance of this engagement extends beyond a single visit. While the U.S. Department of Energy operates 17 national laboratories, none is located along the Gulf Coast, a region uniquely home to industry, infrastructure, and energy systems at commercial scale. HETI’s continued work with the national laboratories helps bridge that geographic and operational gap by connecting world-class scientific research with companies that understand how to scale and deploy technologies. The Argonne fly-in also created space to address practical barriers to collaboration, including complex agreements and lengthy contracting timelines, and to explore ways to establish partnership frameworks more efficiently.

Explore HETI’s key takeaways from the fly-in:

1. Scaling Technologies for Commercial Use

A central theme was the importance of scale-up infrastructure and the role Argonne plays in helping companies reduce technical and manufacturing risks. Participants learned how facilities such as the Materials Engineering Research Facility (MERF) support the transition from laboratory discoveries to pilot-scale production and ultimately commercial manufacturing. These capabilities are especially valuable for companies working to move promising technologies from concept to market.

The discussions also highlighted Argonne’s extensive work in critical materials, battery recycling, advanced manufacturing, and supply chain resilience. Attendees learned about initiatives including the ReCell Center, AI-enabled materials discovery, and advanced modeling tools that can help businesses understand supply chain vulnerabilities and evaluate mitigation strategies. These capabilities have applications across energy, chemicals, manufacturing, semiconductors, defense, and emerging technologies.

2. Creating Pathways for Collaboration

Another key takeaway was the importance of engaging early. Companies do not need to arrive with a fully developed project or solution. Argonne offers multiple pathways for collaboration, including sponsored research, user facility access, technology licensing, pilot-scale testing, and Cooperative Research and Development Agreements (CRADAs). These partnerships help companies access specialized expertise, facilities, and analytical tools that can accelerate innovation and commercialization

3. Building Connections Across Industry and Research

The fly-in reinforced the value of relationship building. Bringing together nearly 20 organizations in one place created meaningful opportunities for collaboration, knowledge sharing, and identifying future projects.

The conversations throughout the day demonstrated a shared commitment to strengthening domestic innovation, developing resilient supply chains, and creating pathways to bring new technologies to market.

Fervo produces first geothermal power at flagship Utah project

energy milestone

Fervo Energy’s flagship project in Utah just generated its first geothermal power.

The electricity is now flowing to the power grid from one of Cape Station’s three generation units, Houston-based Fervo said in a news release. This represents an early but important milestone for the project, as the unit isn’t scheduled to deliver contracted power until Oct. 1.

The achievement, coming four months after Fervo’s roughly $2.2 billion IPO, demonstrates the viability of enhanced geothermal systems (EGS).

“This is a gamechanger for the geothermal industry. It establishes EGS as the defining new power generation technology of our time, and we believe it shows that the commercial and technical maturity of EGS is ready to meet the urgent need for reliable, clean power,” Tim Latimer, co-founder and CEO of Fervo, said in the release.

The plant’s two other units are scheduled to launch commercial operations on Jan. 1.

The three units make up the project’s 99-megawatt first phase. The next phase, which will add 400 megawatts of capacity, is under construction. The second phase is set to go online in 2028.

Altogether, Cape Station will provide more than 4 gigawatts of capacity, with 900 megawatts already spoken for. The 900 megawatts of contracted electricity would be enough to power nearly 1 million U.S. homes per year.

“Cape Station works because we treated the subsurface like an engineering challenge,” Jack Norbeck, co-founder and chief technology officer of Fervo, added in the release. “Years of drilling, completion design, subsurface modeling, and flow testing led to this moment, and this is the validation that matters most.”

Enhanced geothermal continuously draws on heat that’s deep underground, producing electricity around the clock regardless of weather or time of day. That makes it one of the only carbon-free resources capable of constant power delivery, which is critical for data centers and AI infrastructure.
