Geothermal heat and power plant

Cheap heat & power for municipalities generated from a local source

Geothermal heat and power plant is a standardized power plant that challenges common geothermal energy approaches. It makes geothermal more efficient and reduces the CO2 lifecycle footprint to a bare minimum. Cheap heat & power for municipalities generated from a local source.

It is a new variant of geothermal energy with technology that fully utilizes the energy potential of hot brines. In contrast to conventional geothermal power plants, its advanced system uses two sources for its energy production: hot water as well as the combustible gases dissolved in it. The gases are separated from the water and burned in a gas engine. The CO2 from combustion, as well as any brought up with the hot water, is captured and safely re-injected into the aquifer. The result: remarkably cost-effective renewable and zero-carbon energy.
