2.2. CAES operational parameters. CAES devices store electrical energy by using an electric motor to compress air, which is then stored in a reservoir (typically an underground formation). Compressed air is then used at a later time to generate electricity by expanding the compressed air through a series of turbines.
Compressed air is produced by forcing air into a container and keeping it at a pressure greater than the external (atmospheric) pressure. This pneumatic energy is used for many applications, including: pneumatic handtools. glass manufacturing. fermentation, clarifying and bottling of beverages. spray painting.
