Sage Geosystems

In just 12 months, Sage Geosystems and San Miguel Electric Cooperative built the world’s first pressure geothermal system. It is now poised to deliver long-duration, dispatchable storage for the Electric

Geothermal energy has been utilized by humans for millennia. While the first-ever use may be a mystery, we do know the Romans tapped into it in the first century for hot baths at Aquae Sulis (modern-day Bath, England). Since then, many other people and cultures have found ways to use the Earth’s underground heat to […]

The U.S. Department of the Air Force has awarded Sage Geosystems an initial $1.9 million contract to demonstrate its pioneering geothermal baseload power and energy storage system at an off-site test well in Starr County, Texas.  When completed as planned in 2025, the demonstration will become the first Geopressured Geothermal Systems (GGS) facility in the […]

Sage Geosystems will build a first-of-its-kind 3-MW geothermal baseload power and energy storage system on land owned by San Miguel Electric Cooperative (SMECI) in Christine, Texas. The company plans to begin operating the project later this year to supply the Electric Reliability Council of Texas (ERCOT) grid. The project will mark the first commercial-scale deployment […]

A handful of geothermal projects are crossing from experimentation into execution, testing whether drilling gains, reservoir control, and new market demand can turn subsurface risk into firm, contractable power. Since 2021, geothermal power’s proposition has been quietly shifting, driven primarily by encouraging policy, but also a new class of decisive buyers. In response to reliability […]
