Electric power storing device for storage tank power plant, recovers potential energy generated by emptying tank into surrounding waters using pump devices under application of electric energy, during filling of tank
The device has a tank (1) filled with water, which is arranged on a seabed (6). The potential energy generated by emptying the tank into surrounding waters using hydraulic or pneumatic pump devices under the application of electric energy, is recovered during filling of the tank. The flowing amount of water is regulated so that the power of turbine (8) and generator (9) is adapted to the requirement of electricity grid (12). The air chamber (3) of the tank is connected to external air through pipe (2) or hose so as to enable compression-free exchange of air. An independent claim is included for method for storing electric power.
