METHOD AND SYSTEM FOR COMBINED PUMP WATER PRESSURE-COMPRESSED AIR ENERGY STORAGE AT CONSTANT TURBINE WATER PRESSURE

摘要

A method for the combined pump water pressure-compressed air energy storage at a constant turbine water pressure, the energy to be stored is used to pump a liquid medium into a pressure vessel such that a rising level of medium compresses the gas contained in the pressure vessel through a connecting conduit and presses said gas into a compressed gas tank, the conduit being shut using a check valve such that the energy is stored in the compressed gas.
