Abstract (en)
[origin: WO2013138667A1] Various techniques may be employed alone or in combination to allow efficient storage and recovery of energy from compressed gas. In certain embodiments, a hydraulic motor may capture energy released by depressurization of a separated heat-exchange liquid that was pressurized during gas compression. Particular embodiments may be employed in conjunction with a heat engine. According to some embodiments, a compressed gas storage unit may include a gas-liquid interface between a liquid portion and a gas portion, with a hydraulic pump/motor capturing energy of liquid displaced by an inflow of compressed gas.
