A team headed by Franz Georg Pikl, a PhD student at the Institute of Hydraulic Engineering and Water Resources Management at TU Graz, has combined the advantages of pumped storage technology and heat storage using water as a medium to create a “hot-water pumped storage hydropower plant”. The new system stores and supplies electricity, heat and cooling energy as required.
