Sage Geosystems has raised $17 million in Series A funding to support the development of its Geopressured Geothermal System (GGS) in Texas. The funding will be used to build a 3MW commercial facility, called EarthStore™, which will utilize Sage Geosystems’ innovative technology to store energy from pressurized water stored deep underground. The facility will be able to store energy for short and long duration periods and can be paired with intermittent renewable energy sources to provide baseload power to the electric grid. Construction of the facility is set to begin in Q2 2024.
