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 …

Flywheel Energy Storage Explained

Share this post. Flywheel energy storage systems (FESS) are a great way to store and use energy. They work by spinning a wheel really fast to store energy, and then slowing it down to release that energy when needed. FESS are perfect for keeping the power grid steady, providing backup power and supporting renewable energy sources.

The minimum speed of the flywheel is typically half its full speed, the storage energy is be given by ½ (1 2-0.5 2) I f w f 2 where I f is the rotor moment of inertia in kgm 2 and the w f maximum rotational speed in rad/s. The power level is controlled by the size of the M/G, so this is independent of the rotor.
