# Sage Geosystems

> Sage Geosystems is a Houston enhanced geothermal developer that engineers reservoirs in hot rock to produce electricity and store energy underground as pressure. Its South Texas facility has supplied electricity and produced operating data for a planned two-well project at Ormat's Blue Mountain plant in Nevada. The company serves utilities, data center demand and defense energy needs through project development, technology partnerships and long-duration storage.

- **Founded:** 2020
- **Headquarters:** Houston, United States
- **Founders:** Lev Ring (Co-founder; president and chief technology officer), Lance Cook (Co-founder; chief scientist), Cindy Taff (Co-founder and chief executive officer; joined after the 2020 launch)
- **Products:** Pressure Geothermal / GGS, EarthStore, GeoTwin, Geothermal project development
- **Notable:** Sage's 2023 pilot reported 200 kW for over 18 hours and 1 MW for 30 minutes; those were pilot results, not sustained commercial output., Its SMECI facility sold first electricity in Q2 2026 and reported more than 120 operating days by August 2026., Sage reported less than 10% water loss across multiple cycles at SMECI and said GeoTwin predicted observed operating behavior.

## Products & services

- **Pressure Geothermal / GGS** — Engineered geothermal reservoirs in hot rock circulate water through wells and use subsurface heat and pressure for firm power generation.
- **EarthStore** — A single-well long-duration storage system that pumps water into deep fractures when electricity is available and recovers pressure energy when needed.
- **GeoTwin** — A subsurface modeling tool used to predict reservoir operating behavior and inform project design.
- **Geothermal project development** — Site assessment, well development, reservoir engineering, power and storage project design with utilities, industrial partners and government customers.
