Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance;[4] full-cycle lifetimes quoted for flywheels range from in excess of 105, up to 107, cycles of use),[6] high energy density (100–130 W·h/kg, or 360–500 kJ/kg),[6][7] and large maximum power output.
This energy is used to set the flywheel in motion. Energy storage: As the flywheel spins, it stores kinetic energy. The energy can be stored as long as the flywheel continues to spin. The flywheel is often located in a vacuum environment and mounted on magnetic bearings to reduce energy loss.
Flywheel energy storage systems have a long working life if periodically maintained (>25 years). The cycle numbers of flywheel energy storage systems are very high (>100,000). In addition, this storage technology is not affected by weather and climatic conditions .
Flywheels, one of the earliest forms of energy storage, could play a significant role in the transformation of the electrical power system into one that is fully sustainable yet low cost.
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 .
Think of it as a mechanical storage tool that converts electrical energy into mechanical energy for storage. This energy is stored in the form of rotational kinetic energy. Typically, the energy input to a Flywheel Energy Storage System (FESS) comes from an electrical source like the grid or any other electrical source.
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. Flywheel energy storage system topology.

Additionally, flywheel systems can store energy for long periods without significant energy loss. Flywheels also have a longer lifespan than chemical batteries, potentially operating for over 20 years. What are the Advantages and Disadvantages of Flywheel Energy Storage?
The existing energy storage systems use various technologies, including hydroelectricity, batteries, supercapacitors, thermal storage, energy storage flywheels, [2] and others.
