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.
The aCQurate (accurate CO2 monitoring using Quantitative joint inversion for large-scale on-shore and off-shore storage applications) project aims to develop a new technology for quantitative CO2 monitoring applicable to large-scale on-shore and off-shore sites, e.g. on the Norwegian Continental Shelf.
The project H2_ReacT researches fundamental aspects of the geological storage of hydrogen. The project aims to derive experimental data on the kinetics of chemical reactions and microbial processes as well as on transport mechanisms of molecular hydrogen in deep geological systems under in-situ conditions.
