The use of aquifers for storage of thermal energy implies a use of both the thermal storage capacity of ground water as well as that of the water-saturated rock. Both heat and cold can be stored. The storage capacity of an aquifer is large compared to other thermal storage systems due its large mass. For this reason, aquifers are often used for seasonal or long-term energy storage.
Further investigations at the Geothermal Research Platform Groß Schönebeck are carried out in order to show, if the geothermal potential of the North-German Basin (NGB) can be utilized for electricity generation with a fracture-dominated development of the deep geothermal reservoir in the Rotliegend.
The GEMex project is a joint effort of a European consortium (24 partners) with a corresponding consortium from Mexico (9 partners). GEMex focusses on resource assessment and characterization based on the combination of novel and conventional technologies at two geothermal systems in the Mexican Volcanic Belt. Concepts for site development will evolve from the project. GEMex is coordinated by GFZ.
