About us

The Swiss Energy Strategy 2050 envisages considerably increasing the share of renewable energies. Geothermal energy, using the heat captured in the deep underground, is one such source. In the “Bedretto Underground Laboratory for Geoenergies”, ETH Zurich studies techniques and procedures for a safe, efficient, and long-term use of geothermal heat in close collaboration with national and international partners. To this aim, a unique research infrastructure was established. It is located 1.5 kilometers below surface in the middle of a 5.2-kilometer long tunnel connecting the Ticino with the Furka tunnel.
