In the context of the energy transition, especially in view of securing the base load capacity of alternative energy sources, subsurface energy storage will increasingly gain importance. The key aspects of this joint research project are dimensioning, risk analysis, and impact assessments of subsurface energy storage as a basis for the spatial planning of the subsurface. 

The main objectives of the department MET are to develop strategies for the geothermal exploration and implement an effective impact monitoring for an optimized use of shallow subsurface heat storage. Therefore, a multi-scale approach is applied which includes laboratory tests geophysical/hydrogeological field investigations as well as model applications.
