Method for storing electrical energy into potential energy and for storing potential energy into electrical energy in deep water storage power plant, involves applying heavy loads with high density for storing electrical energy

摘要

The method involves applying heavy loads with high density, such as concrete for storing electrical energy. The supply of electrical energy in grid or acquisition of electrical energy is carried out by lowering and lifting the load in deep sea area. A generator (7) is acuated by a shaft (1) while lowering the load by a mechanical gear mechanism (3). The effect of force is reversed while lifting the load and a cable drum (2) is driven by the shaft. The electrolysis system is run in electrically isolated operation to produce hydrogen and oxygen with the acquired electrical energy.
