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

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.

Lectures & Courses


X.‑Z. Kong, A. Ebigbo, 651-4240-00L
This course presents advanced topics of single and multiphase fluid flow, heat transfer, reactive transport, and geochemical reactions in the subsurface. Emphasis is on the understanding of the underlying governing equations of each physical and chemical process, and its relevance to applications, e.g., groundwater management, geothermal energy, CO2 storage, waste disposal, and oil/gas production.
