Finally, the high pressure liquid CO 2 (state 11) expands through the cryo-turbine to the required storage pressure, and the produced liquid CO 2 (state 13) is stored for the energy recovery use. At peak hours, liquid CO 2 (state 16) is pumped to the discharging pressure (state 17) and transfers its cold energy to methanol through CR 2 .
An alternative to those systems is represented by the liquid air energy storage (LAES) system that uses liquid air as the storage medium. LAES is based on the concept that air at ambient pressure can be liquefied at −196 °C, reducing thus its specific volume of around 700 times, and can be stored in unpressurized vessels.
