Gaseous air is compressed during the charge phase and converted into liquid air by passing through a phase separator and J-T valve. A low-pressure cryogenic tank holds the liquid air (LA Tank). A high-grade cold storage (HGCS), which doubles as a regenerator, stores the extra cold released during regasification.
