Fundamentally, flywheels store kinetic energy in a rotating mass known as a rotor [[6], [7], [8], [9]], characterized by high conversion power and rapid discharge rates [10].

Flywheels store energy in the form of rotational energy. A flywheel is, in simple words, a massive rotating element that stores energy by speeding up and maintaining its angular speed.
