The brief

Analyst view

• SMECI 3 MW pilot in South Texas completed 120+ days of operations, validating geopressured EGS technology.
• Ormat co-led $97M Series B in January 2026. Project Vector partnership at Blue Mountain, Nevada announced September 2026.
• Meta signed 150 MW geothermal power agreement in August 2024; first phase operational 2027.

Technical approach

As reported

Pressure circulation

Pumped heat transfer without reservoirs

Cool water down one well absorbs heat from rock; hot water circulates up second well to generate power.

Geopressured systems

Uses deeper, hotter rock strata

Geopressured layers (sandstone, shale, clay) under sediment hold extreme heat and pressure for economical extraction.

Data center scale

Baseload power 24/7

Geothermal delivers continuous power, unlike wind or solar. Sage targets 24/7 supply for data center operators who need reliable grid backstops for AI compute.

Flexible thermal loads

Heat storage and power on demand

The technology can store thermal energy for 8+ hours, allowing dispatch on demand or rapid ramp to support grid stability when paired with renewables.
