Cryogenic Energy Storage

Cryogenic energy storage (CES) refers to a technology that uses a cryogen such as liquid air or nitrogen as an energy storage medium [1]. Fig. 8.1 shows a schematic diagram of the technology. During off-peak hours, liquid air/nitrogen is produced in an air liquefaction plant and stored in cryogenic tanks at approximately atmospheric pressure (electric energy is stored).
