READ MOREAs promising as compressed air appears as a storage medium, it does have some drawbacks. When air is compressed, it heats up. When it expands, it cools. Cold air isn''t as effective at producing power when it is run through a turbine, so before the air can be used, it needs to be heated, frequently using natural gas, which produces CO
READ MORECompressed air energy storage (CAES) is a method of compressing air when energy supply is plentiful and cheap (e.g. off-peak or high renewable) and storing it for later use. The main application for CAES is grid-scale energy storage, although storage at this scale can be less efficient compared to battery storage, due to heat losses. Unlike
