Abstract

A system for converting electricity into pressurized air, and converting pressurized air into electricity. The system includes a pressurized air reservoir, two high pressure tanks, a pump and an electrical motor convertible into a hydro turbine and an electricity generator, a volume of water equal to a tank's volume, a set of controllable valves for connecting and disconnecting independently each tank, to the atmosphere, to the pump inlet and outlet, and to the air reservoir. In use, a volume of water in the first tank is pumped into the second tank, the air in the second tank is compressed and flows into the air reservoir. By changing position of the valves, the operation repeats with opposite roles of the tanks. In an electricity generating mode, the system operates by transferring pressurized air from the air reservoir into the first tank which is full of water, the pressurized water flowing through the hydro turbine generator thereby generating electricity.
