Cutting-edge technologies to advance geothermal energy in Switzerland

ZeroGeo Energy uses Hot Dry Rock (HDR) technologies to offer renewable energy storage and low-carbon baseload power generation in Europe.

The TerraThermo™ joint venture between ZeroGeo and Sage Geosystems Inc. will utilize Sage’s EarthStore™ and Battery+™ technologies to develop renewable energy storage and baseload power generation projects in Europe.

How is our well engineering different from other Hot Dry Rock Technologies?

Scalable from storage to baseload power production

Renewable baseload power generation

Our technology allows for renewable baseload power production by cycling multiple wells.

• Closely spaced wells, using pad drilling techniques common in the oil and gas industry, provide significant operational efficiencies and cost-effective scaling.
• After injecting fluid under pressure (< 1’000 PSI) into the downhole fractures and harvesting heat from dry rock, the fluid is allowed to return to the surface (driven by the fracture closure pressure) to power an sCO2 turbine for highly efficient electrical conversion.
• Each well alternates between injector and producer (like a multi-cylinder engine) and can produce > 3 MW of power per well.

We use downward-oriented HeatRoot™ Fractures
