When new tunnel structures are constructed in inner cities, this provides an excellent opportunity to also tap geothermal energy parallel to this and with little expenditure and effort. This energy can be used, for example, for heating and cooling buildings.

The BINE Projektinfo “Air-conditioning with geothermal energy from underground metro tunnels” (09/2013) presents a research project in Stuttgart. The aim is to research the effects of extracting heat from the surrounding ground.
