Storage power station e.g. pump storage power station, for conversion of potential energy of stored water into electric energy, has water-filled rock layers and/or soil transformations functioning as energy storages and/or reservoirs

摘要

The station has water-filled rock layers e.g. sub-terrestrial caves and/or cave lakes, cirques and lakes, with lower and upper reservoirs (4, 8) and/or soil transformations functioning as energy storages and/or reservoirs for obtaining need-based electrical energy from water in the rock layers in combination with wind energy. A sterling motor (5) utilizes geothermal energy of the rock layers and hot water and/or thermal energy for obtaining mechanical energy to drive conveyor pumps (6). The rock layers are sealed with water-proof concrete.
