Kurzbeschreibung (Abstract)

Geothermal energy can play an important role in the decarbonization of the German energy system. In order to make the great potential of geothermal energy in the crystalline basement economically viable, measures are taken to enhance existing permeable structures. However, a prerequisite for the public acceptance of such Enhanced Geothermal Systems (EGS) is the minimization of possible induced seismicity. Their control can only be based on an understanding of the processes and interactions of the fluid with the reservoir. With the generic underground laboratory GeoLaB (Geothermal Laboratory in the Crystalline Basement), fundamental questions of reservoir technology and borehole safety of EGS are to be investigated. The planned experiments will significantly improve our understanding of the relevant processes in the fractured crystalline rock under increased flow rates. The application and development of state-of-the-art observation and evaluation methods will lead to findings that are of great importance for a safe and ecologically sustainable use of geothermal energy and the underground. As an interdisciplinary and international research platform GeoLaB will generate synergies and technical-scientific innovations in cooperation with the German Research Foundation, universities as well as industrial partners and specialized authorities.
