When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of the flywheel. . Flywheel energy storage (FES) works by spinning a rotor (flywheel) and maintaining the energy in the system as rotational energy. Electrical energy is thus converted to kinetic energy for storage. In this chapter, the requirements for this safety-critical component are discussed, followed by an analysis of historical and contemporary burst containment. . Abstract - This study gives a critical review of flywheel energy storage systems and their feasibility in various applications. This innovative technology offers high efficiency and substantial environmental benefits.
