the rise of flywheel energy storage

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.

Flywheel Energy Storage System

Flywheel energy storage system (FESS) is an electromechanical system that stores energy in the form of kinetic energy. A mass coupled with electric machine rotates on two magnetic bearings to decrease friction at high speed. The flywheel and electric machine are placed in a vacuum to reduce wind friction.
