Sage Geosystems

What Sage Geosystems does

Sage Geosystems is a Houston, Texas-based privately held pressure geothermal company founded by veterans of the oil and gas industry, including former Shell executive and CEO Cindy Taff, with leadership claiming 30+ years of drilling experience across 5,000+ wells globally. The company has developed two related subsurface technology platforms: a two-well Pressure Geothermal system that uses engineered "lung" fractures in hot dry rock (designed for depths up to 20,000 feet and temperatures of 180°C+) to circulate water under pressure, transfer subsurface heat, and drive a proprietary supercritical CO2 (sCO2) turbine at the surface; and a single-well EarthStore™ mode that provides long-duration mechanical energy storage (8+ hours to multi-day) using subsurface pressure cycles paired with a Pelton turbine. Together these technologies are positioned to deliver firm, 24/7, dispatchable baseload power and grid-stabilizing storage from a geographically unrestricted hot dry rock resource.

The company's commercial traction is anchored on three enterprise offtake channels. First, long-dated Power Purchase Agreements with hyperscale data center operators, headlined by a 150 MW PPA with Meta signed in August 2024 with first-phase delivery targeted for 2027. Second, strategic co-development and build-own-operate agreements with established geothermal operators, most notably a strategic commercial agreement with Ormat Technologies (August 2025) under which Ormat gains rights to develop, build, own, and operate Sage-powered plants, and will host the first commercial pressure geothermal power generation facility at an existing Ormat site in Nevada (2027). Third, defense and utility deployment, including DoD feasibility studies and demonstrations at Fort Bliss, Naval Air Station Corpus Christi, and Ellington Field, and a commissioned 3 MW energy storage facility at the San Miguel Electric Cooperative (SMECI) site in Christine, Texas, which began cycling in Q1 2025.

Sage Geosystems earns revenue (or near-term revenue potential) through three distinct streams: recurring PPA-based baseload power revenues tied to large energy buyers like Meta; technology licensing, milestone, and royalty income from strategic commercial agreements with operators like Ormat; and long-duration energy storage services sold to electric cooperatives, utilities, and renewable developers. The company has raised over $97 million in a Series B closed in January 2026 (co-led by Ormat's $25 million equity commitment and Carbon Direct Capital) on top of a $17 million round in February 2024, with strategic backers including Meta, SiteGround Capital, Nabors Industries, GeoLog, Expand Energy, ABB, California Resources Corporation, and several climate-focused funds. Pricing is not publicly disclosed; commercial contracts are negotiated project-by-project. The company is pre-revenue with its first operational commercial facility (3 MW storage at SMECI) cycling since Q1 2025, with the first commercial power generation facility targeted for 2027.

Revenue model

1. Long-term Power Purchase Agreements (PPAs): Multi-year, multi-megawatt offtake contracts with major energy buyers (e.g., Meta 150 MW PPA signed August 2024) providing recurring baseload power revenue once commercial projects come online; targeted $1.11-1.16B sector revenue context per Ormat 2026 guidance points to large-scale recurring revenue potential.
2. Technology licensing / Strategic commercial agreements: Co-development and licensing arrangements with strategic operators (Ormat) granting rights to develop, build, own, and operate Sage-powered plants, generating upfront investment, milestone payments, and ongoing royalties.
3. Long-duration energy storage services: Long-duration energy storage services (8+ hours to multi-day) sold to utility cooperatives, renewable generators, and grid operators (e.g., San Miguel Electric Cooperative 3 MW facility in Christine, TX) to stabilize the grid and integrate intermittent renewables.
4. Strategic equity investment capital: Capital raises from strategic corporate investors (Ormat $25M, Meta, Carbon Direct Capital, SiteGround Capital) to fund project development and technology deployment ahead of commercial revenue.
