Energy Storage

Salt Caverns

Large underground stores are required for fluctuating renewable energy resources. The frequent loading and unloading of salt cavern arrays is investigated from a geomechanical point of view.

Thermo-Chemical Heat Storage (NUMTHECHSTORE)

NUMTHECHSTORE

Thermal energy storage is of high strategic relevance for a sustainable energy system. The development of next generation storage systems like thermochemical solutions is accompanied by major scientific challenges. Due to the complexity of the considered storage systems and the exceptional efforts for the development of storage materials as well as for the implementation of large-scale experiments, modelling and numerical simulation are of outstanding importance for the prediction of the operational behaviour and the optimisation of thermochemical heat storage systems.
