A startup announced Tuesday that it has inked a deal in central Texas allowing it to build the world’s first geothermal energy storage project that delivers power to the grid.
Houston-based Sage Geosystems said it has a land-use agreement with San Miguel Electric Cooperative to develop a 3-megawatt energy storage facility in Christine, Texas.
The Sage project, known as EarthStore, will be near San Miguel’s 391-MW coal-fueled power plant and an associated mine. Construction on the geothermal facility started last week and the project is expected to be ready before the end of 2024, the company said.
“Once operational, our EarthStore facility in Christine will be the first geothermal energy storage system to store potential energy deep in the earth and supply electrons to a power grid,” said Cindy Taff, Sage’s CEO, in a statement.
