Sage Geosystems company profile

Sage Geosystems develops geothermal and energy storage technologies that use subsurface heat and pressure to generate and store electricity. The company’s offerings include systems that store energy underground during low demand and release it to produce power when needed, and technologies that extract geothermal energy for continuous power generation. Its platform supports integration with intermittent renewable sources and grid applications, including long-duration storage and consistent electricity supply. Sage also works with partners on pilot projects and commercial deployments that apply its geothermal and storage systems to utility and infrastructure use cases.
