How is air purified during charging?

During charging, the purified air is compressed via multistage compression, cooled by the stored cold energy, and recirculating cold air. The air then flows through a cryoturbine or Joule–Thomson throttling valve and becomes liquid air, which is stored in a cryogenic (Cyro) tank (∼78 K and near-ambient pressure).

What is a CAES energy storage system?

CAES is a relatively mature energy storage technology that stores electrical energy in the form of high-pressure air and then generates electricity through the expansion of high-pressure air when needed.
