Tunnel construction as a climate-friendly source of energy

Tunnel construction as a climate-friendly source of energy The Brenner Base Tunnel will relieve transit traffic between Italy and Austria and, incidentally, supply parts of Innsbruck with geothermal energy. The source of energy is the tunnel water. 17 March 2021 Brenner Basistunnel (c) BBT SE When tunnels are bored through mountains, it is not the groundwater level that is an issue but the mountain water level. Mountain water comes from precipitation and flows down from the mountain surface. Along the way, its temperature is increased by the earth’s heat. “Geothermal energy is largely generated by the decay of long-lived nuclides in the earth’s interior,” says Thomas Geisler of the Institute of Rock Mechanics and Tunneling at Graz University of Technology. “As such, it is an entirely natural heat source fed by the Earth’s interior.” Unlike wind turbines, which only provide energy when the wind is blowing, geothermal energy is basically available around the clock an

Tunnels to become CO2-neutral energy suppliers

A research association led by TU Graz is exploring the possibilities. view more Credit: © BBT SE After completion in about ten years, the Brenner base tunnel is expected to provide relief for transit traffic between Italy and Austria. The Brenner Base Tunnel Company (BBT SE) and Innsbrucker Kommunalbetriebe (Innsbruck municipal works) now want to generate an additional benefit together with the Institute of Rock Mechanics and Tunnelling at Graz University of Technology and determine the geothermal potential of the tunnel, as Institute head Thomas Marcher explains: We are investigating whether and how drainage water from the Brenner base tunnel can be used for climate-friendly heating and cooling of houses or even entire neighbourhoods in Innsbruck.
