Company Overview
Sage Geosystems is a geothermal energy technology company founded in 2020 and headquartered in Houston, Texas. The company is developing solutions to make geothermal energy more accessible, affordable, and available in diverse geological locations, not just traditional volcanic regions. Sage Geosystems leverages existing oil and gas technologies and expertise to create its proprietary Geopressured Geothermal System (GGS), which harnesses both the Earth's heat and pressure to generate power. This approach aims to be more efficient than other geothermal technologies. The company is also developing energy storage solutions, such as its EarthStore™ facility, designed to store energy for long durations and support intermittent renewable sources like wind and solar. Sage Geosystems has secured Series A funding and is actively developing commercial facilities, with partners including the U.S. Department of Defense and Meta.
