Research
GeoLaB serves as a nucleus for the development of environmental-friendly, innovative geothermal technologies and ensures close interaction with society. The following research objectives can be realized for the first time in GeoLaB:
- Controlled high-flow experiments (CHFE) as basis for an efficient and sustainable management of fractured reservoirs
- State-of-the-art multidisciplinary THMC+ research with innovative visualization concepts and a "digital twin"
- Development of new environmentally friendly strategies for underground facilities
- Acceptance research and transparent interaction with the public and decision-makers
The complex processes that take place in the crystalline rock during deep geothermal utilization are hidden deep underground and can only be inadequately observed from the borehole or the surface. The Black Forest and Odenwald offer science a unique opportunity: The reservoir rock of the Upper Rhine Graben, which lies there at a depth of several kilometers, has been uplifted here and is thus accessible to science. Experiments could therefore be carried out here from a tunnel under conditions similar to those in the reservoir. The processes taking place can be observed here in three dimensions with a dense network of sensors.
The planned experiments will contribute significantly to the understanding of the processes associated with increased flow rates in crystalline rocks. The application and development of state-of-the-art monitoring and analysis tools will provide fundamental insights that are of great importance for a safe and ecologically sustainable use of geothermal energy and other subsurface resources.
In doing so, GeoLaB creates synergies with complementary underground laboratories worldwide and will leave a lasting mark on the geosciences.
