A geothermal company with Houston ties has made a strategic acquisition.

CeraPhi Energy acquired the business of Third Energy Limited, which is a former fracking company, with plans to repurpose the existing wells into clean geothermal energy centers. The terms of the deal were not disclosed.

The acquisition is set to include subsidiaries like Third Energy Trading Limited, Wolfland Renewables Limited, Wolfland Utilities Limited, Third Energy UK Gas Limited, and 50 percent holding in West Heslerton Renewables Limited.

The assets are located in North Yorkshire U.K. and include eight well sites consisting of 12 former gas wells in a suspended state, 22.4 km of 6-inch and 16.6 km of 3-inch subterranean pipelines and a further 22.4 km of buried fiber optic comms lines.

CeraPhi, which has a Houston office in Greentown Labs, completed a commercial demonstration of its CeraPhiWell system in 2023 using the Third Energy KMA site.

The company's strategy aims to “de-risk the scaling and commercialisation of large-scale heat networks using boreholes down to a depth of 2km, reducing the space required for deployment of large-scale systems and increasing the extraction of thermal energy available for network connections,” according to its website.

“By using the inexhaustible resource beneath our feet using closed-loop technology we can access this energy anywhere with zero environmental risk, requiring no hydraulic fracturing, no use of water and providing enough energy within the next 15 years to solve our energy crisis indefinitely,” says CEO Karl Farrow in a news release.

Sage Geosystems, a Houston-based developer of geothermal power systems, has chosen a site in Nevada for its commercial-scale Project Vector facility.

The company’s two-well enhanced geothermal system (EGS) will deliver around-the-clock geothermal heat to Ormat Technologies’ Blue Mountain geothermal power plant in Winnemucca, Nevada.

The startup expects to begin drilling the first well later this year, with the first electricity to be generated in 2027 and full-scale production to start in 2028.

In the Nevada system, fluid will circulate through an engineered subsurface reservoir, absorb heat from the surrounding rock and return heat to the surface. The heat will be delivered to the Blue Mountain plant for conversion into electricity.

Project Vector builds on the performance of Sage’s SMECI facility in South Texas. That facility’s results, combined with Sage’s digital twin platform, will be used to shape to the design and development of Project Vector.

Project Vector supports Sage’s growing commercial pipeline, including a 150-megawatt geothermal power agreement with Meta Platforms, the parent company of Facebook and Instagram.

“Blue Mountain is an ideal location for Sage to take the next step in continuing to commercialize our proprietary EGS approach,” Jason Peart, chief operating officer at Sage, said in a release. “By delivering geothermal heat into an existing power plant, Project Vector can demonstrate the model for bringing firm, 24/7 geothermal power to market at scale.”

Project Vector extends Sage’s relationship with Ormat.

In August 2025, Sage and Ormat agreed to accelerate commercialization of Sage’s geothermal technology at an Ormat power plant. This January, Ormat co-led Sage’s $97 million Series B funding round.

Sage, founded in 2020, has raised about $159 million across three funding rounds.

As the startup ramps up its ESG platform, Sage is targeting data centers as customers, among other large-scale users of electricity.

“The energy needs are huge, and they need it now,” CEO Cindy Taff said on Data Center Frontiers’ podcast. “They can’t depend on the grid anymore.”
