COMPRESSED AIR ENERGY STORAGE SYSTEM

摘要

The present disclosure is related to a method of pseudo- isothermal energy conversion between mechanical and pneumatic energy comprising the steps of: providing a gas/liquid unit wherein the gas/liquid unit may be a compression unit filled with gas and a liquid storage unit containing liquid, the compression unit having thermally conductive walls; compressing the gas by pumping the liquid into the compression unit via a liquid pump and producing compressed gas; concurrently transferring the heat created during the compression step through the walls of the compression unit; and transferring the compressed gas into a compressed gas storage unit and thereby storing energy in the form of pneumatic energy of a compressed gas. The method may also include expansion steps wherein the stored pneumatic energy in the form of compressed gas is converted into mechanical energy
