Are flywheel energy storage systems feasible?

Abstract - This study gives a critical review of flywheel energy storage systems and their feasibility in various applications. Flywheel energy storage systems have gained increased popularity as a method of environmentally friendly energy storage.

How does a flywheel energy storage system work?

Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. For discharging, the motor acts as a generator, braking the rotor to produce electricity.

Do power utilities need a flywheel storage system?

Power utilities need innovative ways to store renewable wind and solar energy, during low demand periods, so they can release it after sunset when demand is high. Several innovative power utilities already use flywheel storage systems to maintain power grid frequency. Renewable energy is knocking on flywheel energy’s door.

How much energy does a flywheel store?

Flywheels can store grid energy up to several tens of megawatts. If we had enough of them, we could use them to stabilize power grids. Batteries also started out as small fry, so we should not write off flywheels any time soon. How Does a Flywheel System Store Energy? A flywheel is a mechanical device, that stores and releases rotational energy.
