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.

    Sage Geosystems builds geothermal power generation and energy storage plants; its entire web
    presence is a seven-page Webflow marketing site (home, technology, projects, company, newsroom,
    contact, careers) with no developer, docs, or API path — /developers, /api, /docs, /openapi.json
    and every /.well-known/* probe returned 404, and no GitHub organization exists under the name.
