Great Potential for Aquifer Thermal Energy Storage Systems

Aquifer thermal energy storage systems can largely contribute to climate-friendly heating and cooling of buildings: Heated water is stored in the underground and pumped up, if needed. Researchers of Karlsruhe Institute of Technology (KIT) have now found that low-temperature aquifer thermal energy storage is of great potential in Germany.

Aquifer Thermal Energy Storage for low carbon heating and

Aquifer Thermal Energy Storage (ATES) is an underground thermal energy storage technology that provides large capacity (of order MW t h to 10s MW t h), low carbon heating and cooling to large buildings and building complexes, or district heating/cooling networks.The technology operates through seasonal capture, storage and re-use of thermal energy in shallow aquifers.

Aquifer Thermal Energy Storage

Aquifer Thermal Energy Storage is a sustainable energy supply in which heat and cold are stored via a heat exchanger (counter-current device, TSA) in a water-carrying sand package 90 meters deep in the ground. In summer a building is cooled with groundwater from the cold wells. And in winter a building is heated via the same heat exchanger, but
