Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of th

Compressed Air Energy Storage

The Compressed Air Energy Storage Principle. A CAES plant requires two principal components, a storage vessel in which compressed air can be stored without loss of pressure and a compressor/expander to charge the storage vessel and then extract the energy again. (The latter might in fact be a compressor and a separate expander.)
