Compressed Air Energy Storage




In a caes system, air is compressed in hours of low energy costs, recovering heat from the compressors; in the subsequent expansion, the air get's heated by the thermal energy precedently stored. Compared to existing systems (CAES with combustion) the proposed system does not require connection to the gas network and has no polluting emissions.
