The technology proposed in this article, IUWCAES combines near-isothermal liquid piston compressions (ICAES) with underwater compressed air energy storage (UWCEAS) [16], [17]. Such solution enables high capacity and high efficiency energy storage without wasting useful land surface.
Both methods of Compressed Air Energy Storage are based on compression of ambient air via excess electrical energy, such as that from a wind turbine or photovoltaic cell, to high pressures (up to 70 bar) during times of lower demand.
