Pneumatic Energy & Compressed Air Storage | Planète Energies

Compressed air energy storage (CAES) is a way of capturing energy for use at a later time by means of a compressor. The system uses the energy to be stored to drive the compressor. When the energy is needed, the pressurized air is released. That, in a nutshell, is how CAES works. Of course, in reality it is often more complicated.
