“Sage Geosystems has hit a big milestone out on a rugged tract near San Antonio: The startup is producing power from its first next-generation geothermal plant. The system is just the third of its kind to come online in the U.S. as the sector races to commercialize the source of on-demand clean electricity.

The novel geothermal facility in Texas has been running since April, Sage exclusively shared with Canary Media. The Houston-based firm said the 3-megawatt pilot plant has performed reliably and as predicted after more than 120 days of grid-connected operations…

Sage’s enhanced geothermal system is a type of nascent tech that involves drilling deep into hot rocks and fracturing them to create water pockets, then using the heat to generate power. It’s distinct from the decades-old traditional geothermal plants that rely on what Taff called ​'very unicorn geology' — the few places in the world where a combination of water, heat, and permeable rocks are easily accessible.”
