Geothermal Heat Storage and Heat PumpSystem

An innovative geothermal heat well storage and heat pump system has been commissioned at Lounavoima’s Waste-to-Energy (WtE) plant at the Lounapuisto circular economy park in Salo, Finland. The first phase of the project has been successfully implemented and tested. Upon completion of the project, the WtE plant will have six 2 km deep geothermal heat wells and heat pumps with a combined output of 6 MW. Waste heat produced by the WtE plant is stored in the geothermal heat wells in the summer and used for district heating in the winter.
