Compressed-air energy storage
OverviewTypes of systemsTypesCompressors and expandersStorageHistoryProjectsStorage thermodynamics

Brayton cycle engines compress and heat air with a fuel suitable for an internal combustion engine. For example, burning natural gas or biogas heats compressed air, and then a conventional gas turbine engine or the rear portion of a jet engine expands it to produce work. Compressed air engines can recharge an electric battery. The apparently-defunct
