Principle of Flywheel Energy Storage: A flywheel is a rotating disk or cylinder that stores kinetic energy. When energy is input into the flywheel, it starts spinning, and the kinetic energy is stored in the form of rotational motion. The amount of energy stored in the flywheel is proportional to the mass and the square of the flywheel''s rotational speed. The formula for calculating the

Charging energy is input to the rotating mass of a flywheel and stored as kinetic energy. This stored energy can be released as electric energy on demand. The rotating mass is supported by magnetic bearings which operate in a vacuum to eliminate frictional losses during long-term storage and safety issues [55].

Energy storage in flywheels A flywheel stores energy in a rotating mass. Depending on the inertia and speed of the rotating mass, a given amount of kinetic energy is stored as rotational energy. The flywheel is placed inside a vacuum containment to eliminate friction-loss from the air and suspended by bearings for a stabile operation.

Flywheel energy storage offers numerous advantages, making it a vital technology in the energy sector. One of its primary benefits is efficiency; flywheels can recover up to 80% of the stored energy, ensuring minimal losses during the conversion process.
The energy storage facility provided by flywheels are suitable for continuous charging and discharging options without any dependency on the age of the storage system. The important aspect to be taken note of in this regard is the ability of FES to provide inertia and frequency regulation .
The amount of energy stored, E, is proportional to the mass of the flywheel and to the square of its angular velocity. It is calculated by means of the equation (1) E = 1 2 I ω 2 where I is the moment of inertia of the flywheel and ω is the angular velocity.
It is now (since 2013) possible to build a flywheel storage system that loses just 5 percent of the energy stored in it, per day (i.e. the self-discharge rate).
