Two clean energy companies in Houston have been recruited for geothermal projects at U.S. military installations.

Fervo Energy is exploring the potential for a geothermal energy system at Naval Air Station Fallon in Nevada.

Meanwhile, Sage Geosystems is working on an exploratory geothermal project for the Army’s Fort Bliss post in Texas. The Bliss project is the third U.S. Department of Defense geothermal initiative in the Lone Star State.

“Energy resilience for the U.S. military is essential in an increasingly digital and electric world, and we are pleased to help the U.S. Army and [the Defense Innovation Unit] to support energy resilience at Fort Bliss,” Cindy Taff, CEO of Sage, says in a news release.

A spokeswoman for Fervo declined to comment.

Andy Sabin, director of the Navy’s Geothermal Program Office, says in a military news release that previous geothermal exploration efforts indicate the Fallon facility “is ideally suited for enhanced geothermal systems to be deployed onsite.”

As for the Fort Bliss project, Michael Jones, a project director in the Army Office of Energy Initiatives, says it’ll combine geothermal technology with innovations from the oil and gas sector.

“This initiative adds to the momentum of Texas as a leader in the ‘geothermal anywhere’ revolution, leveraging the robust oil and gas industry profile in the state,” says Ken Wisian, associate director of the Environmental Division at the U.S. Bureau of Economic Geology.

The Department of Defense kicked off its geothermal initiative in September 2023. Specifically, the Army, Navy, and Defense Innovation Unit launched four exploratory geothermal projects at three U.S. military installations.

One of the three installations is the Air Force’s Joint Base San Antonio. Canada-based geothermal company Eavor is leading the San Antonio project.

Another geothermal company, Atlanta-based Teverra, was tapped for an exploratory geothermal project at the Army’s Fort Wainwright in Alaska. Teverra maintains an office in Houston.

Houston-based Catalyze, a developer of independent power systems, announced it has secured an $85 million tax equity investment from RBC Community Investments.

“RBC’s investment in this portfolio demonstrates our commitment to advancing clean energy solutions within local communities,” Jonathan Cheng, managing director at RBC, said in a news release. “We are excited to partner with Catalyze on the strategic deployment of these and future projects.”

The financing will go toward the construction and completion of 75 megawatts of commercial and industrial solar projects nationwide in 2025. Catalyze’s current generation portfolio now totals 300 megawatts of projects in operations and construction.

The transaction will help Catalyze’s existing relationship with RBC, which demonstrates a commitment to advancing renewable energy solutions at scale.

“RBC is a valued financing partner, and we are pleased to further expand our relationship with this latest investment,” Jared Haines, CEO of Catalyze, said in a news release. “This financing enables us to further our mission to bring scalable distributed generation projects to businesses and communities nationwide.”

Catalyze also has other private equity sponsors in EnCap Investments and Actis.

Last May, Catalyze announced that it secured $100 million in financing from NY Green Bank to support a 79-megawatt portfolio of community distributed generation solar projects across New York state.
