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.

Safe geothermal energy


© 3sat nano – TV broadcast from Tuesday 9 May on 3sat nano

Scientists are searching for safer drilling methods: geothermal energy can provide sustainable and clean energy right where we need it – however seismicity may be induced. Scientists at ETH Zurich investigate how to prevent these earthquakes.
