Flywheel energy storage

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. The energy is converted back by slowing down the flywheel. Most FES systems use electricity to accelerate and decelerate the flywheel, but devices that directly use mechanical energy are being developed.

The cost invested in the storage of energy can be levied off in many ways such as (1) by charging consumers for energy consumed; (2) increased profit from more energy produced; (3) income increased by improved assistance; (4) reduced charge of demand; (5) control over losses, and (6) more revenue to be collected from renewable sources of energy

Energy Storage

Flywheel energy storage systems using mechanical bearings can lose 20% to 50% of their energy in 2 hours.[27] Like in a gyroscope, the moving mass has a high angular momentum, which means that the flywheel (and the object where it is mounted on) strives to keep the same orientation.
