In 2015, evidence emerged of the potential for middle-deep geothermal energy in Luxembourg. A geophysical investigation will now be launched to gather further information on the deep subsoil.

The seismic survey relies on ground vibrations, similar to ultrasound, to gain an insight into the subsoil’s structure. Teams place sensors and trucks generate mild vibrations along predefined routes. The aim is to determine the potential of middle-deep geothermal energy.

Geothermal energy uses the thermal energy stored in the earth’s crust. It offers an sustainable alternative to fossil fuels and is becoming increasingly important in Luxembourg.
Near-surface geothermal energy is ideal for single-family homes, while medium-depth geothermal energy can supply larger buildings and energy-intensive districts
