Mission Statement

The Geothermal Energy & Geofluids group is endowed by the Werner Siemens Foundation and investigates reactive fluid (water, CO2, CxHy, N2) and (geothermal) energy (heat, pressure) transfer in the Earth's crust employing computer simulations, laboratory experiments and field analyses to gain fundamental insights and to address a wide range of societal goals and concerns.

Feasibility of geothermal power plants

In cooperation with the Geothermal Energy and Geofluids (GEG) group, ETH Zurich researchers, working at NAGRA’s Grimsel rock laboratory, have retreated deep inside the mountain. By fracturing solid rock, they are hoping to re-examine the feasibility of geothermal power plants based on petrothermal technology. (ETH Globe, 1/2017)
