Flywheel Energy Storage | Efficient Power Solutions

Flywheel Energy Storage (FES) systems refer to the contemporary rotor-flywheels that are being used across many industries to store mechanical or electrical energy. Instead of using large iron wheels and ball bearings, advanced FES systems have rotors made of specialised high-strength materials suspended over frictionless magnetic bearings

Flywheel Energy Storage System Basics

The kinetic energy of a high-speed flywheel takes advantage of the physics involved resulting in exponential amounts of stored energy for increases in the flywheel rotational speed. Kinetic energy is the energy of motion as quantified by the amount of work an object can do as a result of its motion, expressed by the formula: Kinetic Energy = 1
