The flywheel energy storage operating principle has many parallels with conventional battery-based energy storage. The flywheel goes through three stages during an operational cycle, like all types of energy storage systems:
Table 2 lists the maximum energy storage of flywheels with different materials, where the energy storage density represents the theoretical value based on an equal-thickness-disc flywheel rotor. The storage capacity
Flywheel Energy Storage (FES) system is an electromechanical storage system in which energy is stored in the kinetic energy of a rotating mass. Flywheel systems are composed of various
Among all options for high energy store/restore purpose, flywheel energy storage system (FESS) has been considered again in recent years due to their impressive characteristics which are

The application of flywheel energy storage systems in a rotating system comes with several challenges. As explained earlier, the rotor for such a flywheel should be built from a material with high specific strength in order to attain excellent specific energy .
The main components of a flywheel energy storage system are a rotor, an electrical motor/generator, bearings, a PCS (bi-directional converter), a vacuum pump, and a vacuum chamber . During charging, the rotor is accelerated to a high speed using the electrical motor.
Flywheel energy storage systems are feasible for short-duration applications, which are crucial for the reliability of an electrical grid with large renewable energy penetration. Flywheel energy storage system use is increasing, which has encouraged research in design improvement, performance optimization, and cost analysis.
In 1999 , the University of Texas at Austin developed a 7-ring interference assembled composite material flywheel energy storage system and provided a stress distribution calculation method for the flywheel energy storage system.
Flywheel energy storage system to improve the integration of wind generators into a network. In: Proc. of the 5th International Symposium on Advanced Electromechanical Motion Systems (Vol. 2), pp. 641–646. J. Electr.
In the future, the focus should be on how to improve the stability of the flywheel energy storage single machine operation and optimize the control strategy of the flywheel array. The design of composite rotors mainly optimizes the operating speed, the number of composite material wheels, and the selection of rotor materials.
