Where is compressed air stored?

2. Storage: The compressed air is stored, typically in large underground caverns such as salt domes, abandoned mines, or depleted natural gas reservoirs. Above-ground alternatives include high-pressure tanks or specially designed vessels, though these are generally more expensive and limited in capacity.

Which energy storage technology has the lowest cost?

How is high-pressure air stored?

The high-pressure and high-temperature air is cooled before being stored in an air reservoir. The thermal energy can be dissipated into the atmosphere, stored in TES, or used for heating applications. In the discharging process, stored high-pressure air is released whenever the electricity is required.
