These are: • In the absence of smooth continuous energy, to provide continuous smooth energy. For example, in reciprocating motors, flywheels are used because the torque produced by the motor is discontinuous. • A flywheel is used to store energy and then release it. In some cases, energy is released at a speed that the energy source cannot.

What is Flywheel Energy Storage – How Does it Work?
A flywheel is essentially a mechanical battery consisting of a mass rotating around an axis. It stores energy in the form of kinetic energy and works by accelerating a rotor to very high speeds and maintaining the energy in the system as rotational energy. Flywheel energy storage is a promising technology for replacing conventional lead acid
