Liquid air energy storage (LAES), as a form of Carnot battery, encompasses components such as pumps, compressors, expanders, turbines, and heat exchangers [7] s primary function lies in facilitating large-scale energy storage by converting electrical energy into heat during charging and subsequently retrieving it during discharging [8].Currently, the

For energy storage and uninterrupted power supply

Energy is stored by a rotating mass. In order to reduce friction which would cause power losses and heat generation, many systems operate under vacuum. The required vacuum level depends on the rotational speed of the flywheel. Typical targeted pressures are 1·10-1 hPa down to 1·10-3 hPa or even less. As a result, both heat generation and
