Their efficiency is high during energy storage and energy transfer (>90 %). The performance of flywheel energy storage systems operating in magnetic bearing and vacuum is high. Flywheel energy storage systems have a long working life if periodically maintained (>25 years).
One of the most important issues of flywheel energy storage systems is safety. As a result of mechanical failure, the rotating object fails during high rotational speed poses a serious danger. One of the disadvantages of these storage systems is noise. It is generally located underground to eliminate this problem.
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.

A Flywheel Energy Storage System (FESS) is defined as a system that stores energy for a distinct period of time to be retrieved later. There is a class distinction between flywheels used for smoothing the intermittent output of an engine or load on a machine and these energy storage systems.
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 .
A flywheel energy storage system works by applying a torque in the direction of rotation to speed up the rotor, and applying a torque in the reverse direction to slow it down. On one level, it is simple to implement and understand in comparison with many other energy storage methods, and can store and release energy for potentially unlimited cycles.
