Theatre Storage


Storage of electricity as high temperature heat in rocks has potential to be a feasible and scalable solution for integration of wind and solar. Furthermore it could utilize existing thermal power plants otherwise threatened to shut down. Energinet is currently researching this potential in cooperation with Danish utility company Seas-NVE, DTU and other partners including the construction of a pilot plant. The presentation will focus on the potential socio-economic and private economic value of the storage technology as well as integration in the energy system.
