Sage Geosystems

aid: sage-geosystems
name: Sage Geosystems
description: 'Sage Geosystems is a Houston, Texas energy company developing "Pressure Geothermal" — an evolution of traditional
  geothermal that applies subsurface breakthroughs from the oil and gas industry to hot dry rock. Its two-well Power Generation
  system circulates water through engineered "lung" fractures and extracts heat at surface through a heat exchanger driving
  an sCO2 turbine, while its single-well EarthStore energy storage system charges and discharges over 8-hour to multi-day
  timescales for long-duration storage. The company markets to utilities, data centers and government partners rather than
  to developers: as of this profile it operates a seven-page marketing site with no developer portal, public API, SDK, or
  machine-readable specification of any kind.'
