The company closed over $97 million in Series B funding co-led by Ormat Technologies and Carbon Direct Capital, with participation from investors including Abilene Partners, Alfa8, Arch Meredith, Cubit Capital, Exascale Fund, ignis H2 Energy, Nabors Industries, SiteGround Capital, and UC Berkeley Foundation's Climate Solutions Fund. The funding will support deployment of the world's first commercial Pressure Geothermal power generation facility at an existing Ormat power plant, accelerating market entry and scaling to meet demand for firm power, particularly for AI data centers. Sage Geosystems has a strategic commercial agreement with Ormat to expedite commercialization of its technology. In August 2024, the company announced a partnership with Meta to deliver up to 150 MW of new geothermal baseload power east of the Rocky Mountains in the US, supporting Meta's data center expansion. Ormat, a leader in geothermal and renewable energy with approximately 3,400 MW of gross capacity worldwide, brings expertise in power plant engineering, manufacturing, and energy storage. The round aligns with growing demand for enhanced geothermal systems (EGS), positioned to serve hyperscalers needing clean firm power for AI computing, with Sage's pressurized EGS advantaged economically and environmentally.
Feb 2024Series AExpand Energy (lead); Arch Meredith; ignis H2 Energy; Nabors Industries; Virya; Helium-3 Ventures$17MSage Geosystems, a Houston-based clean energy startup founded in 2020, develops geopressured geothermal systems (GGS) that harvest energy from pressurized water deep underground to provide long-duration energy storage, integrating with renewables like solar and wind for baseload power. The technology uses existing oilfield drilling methods to make geothermal more accessible beyond volcanic regions, offering advantages like smaller footprint, no lithium dependency, and higher efficiency. In February 2024, Sage Geosystems raised $17 million in the first close of its Series A round, led by Chesapeake Energy with participation from Arch Meredith, Helium-3 Ventures, ignis H2 Energy (Ignis Energy), Nabors Industries, and Virya. The funds will fully finance EarthStore, a 3MW commercial facility in Texas using GGS technology, with construction starting in Q2 2024 and commissioning targeted for Q4 2024. Prior pilots demonstrated 200kW for 18 hours and 1MW for 30 minutes. Sage plans to generate revenue through engineering services, IP royalties, and technology licensing, with expansion eyed in California, Arizona, and internationally. The company anticipates becoming post-revenue upon successful GGS commercialization.
