That is, it stores energy in the form of kinetic energy rather than as chemical energy as does a conventional electrical battery. Theoretically, the flywheel should be able to both store and extract energy quickly, and release it, both at high speeds and without any limit on the total number of cycles possible in its lifetime.

This is the most traditional and also most commonly used (when talking globally) method of energy storage, in which the mechanism of storage is creating hydraulic height (mainly water) using pumps (i.e., pumping water from a reservoir at a lower altitude to a higher reservoir) during the charging phase.
Energy storage is performed by radius and weight parameters in this method. Fig. 7.8 shows the integration of the flywheel energy storage system with the grid. In this method the stored energy is transferred to the grid by a generator, alternative current (AC)/direct current (DC) rectifier circuit, and DC/AC inverter circuit. Figure 7.8.
The inbuilt motor uses electrical power to turn at high speeds to set the flywheel turning at its operating speed. This results in the storage of kinetic energy. When energy is required, the motor functions as a generator, because the flywheel transfers rotational energy to it.
