A Houston geothermal startup has announced the close of its series A round of funding.

Houston-based Sage Geosystems announced the first close of $17 million round led by Chesapeake Energy Corp. The proceeds aim to fund its first commercial geopressured geothermal system facility, which will be built in Texas in Q4 of 2024. According to the company, the facility will be the first of its kind.

The venture is joined by technology investor Arch Meredith, Helium-3 Ventures and will include support from existing investors Virya, LLC, Nabors Industries Ltd., and Ignis Energy Inc.

“The first close of our Series A funding and our commercial facility are significant milestones in our mission to make geopressured geothermal system technologies a reality,” Cindy Taff, CEO of Sage Geosystems, says in a news release. “The success of our GGS technologies is not only critical to Sage Geosystems becoming post-revenue, but it is an essential step in accelerating the development of this proprietary geothermal baseload approach. This progress would not be possible without the ongoing support from our existing investors, and we look forward to continuing this work with our new investors.”

The 3-megawatt commercial facility will be called EarthStore and will use Sage’s technology that harvests energy from pressurized water from underground. The facility will be able to store energy — for short and long periods of time — and can be paired with intermittent renewable energy sources like wind and solar. It will also be able to provide baseload, dispatchable power, and inertia to the electric grid.

In 2023, Sage Geosystems debuted the EarthStore system in a full-scale commercial pilot project in Texas. The pilot produced 200 kilowatt for more than 18 hours, 1 megawatt for 30 minutes, and generated electricity with Pelton turbines. The system had a water loss of less than 2 percent and a round-trip efficiency (RTE) of 70-75.

EnergyRe, a developer of large-scale renewable energy projects with headquarters in Houston and New York, has signed a renewable energy agreement that will allow Google to invest in and purchase renewable energy credits (RECs) from its projects under development in South Carolina.

Google will be able to pull from energyRe’s portfolio of more than 600 megawatts of new solar and solar storage projects in the state.

The agreement marks the second partnership between the companies. Last year, energyRe and Google signed a 12-year power purchase agreement in which Google would purchase renewable energy from a 435-megawatt solar project. EnergyRe would supply electricity and RECs generated from the solar project to Google to power the equivalent of more than 56,000 homes.

"Strengthening the grid by deploying more reliable and clean energy is crucial for supporting the digital infrastructure that businesses and individuals depend on," Amanda Peterson Corio, head of data center energy at Google, said in a news release. "Our collaboration with energyRe will help power our data centers and the broader economic growth of South Carolina."

EnergyRe's work includes developing high-voltage transmission, onshore and offshore wind, large-scale solar, distributed generation and storage assets in markets around the United States. Its national onshore utility-scale portfolio includes 1,520 megawatts of contracted solar assets and 398 megawatt-hours of contracted battery storage assets.

"This agreement is a milestone in energyRe's mission to develop innovative and impactful clean energy solutions for the future," Miguel Prado, CEO of energyRe, added in the news release."We're honored to partner with Google to help advance their ambitious sustainability and decarbonization objectives while delivering dependable, locally sourced clean energy to meet growing energy demands."

Google aims to achieve net-zero carbon emissions across its operations and value chain by 2030.
