They are commonly used for short-term energy storage applications such as providing backup power to critical loads, stabilizing grid frequency, and smoothing out fluctuations in renewable energy sources such as wind and solar. 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. . Flywheel energy storage stores electrical energy in the form of mechanical energy in a high-speed rotating rotor. The core technology is the rotor material, support bearing, and electromechanical control system. The ex-isting energy storage systems use various technologies, including hydro-electricity, batteries, supercapacitors. . Flywheel energy storage systems (FESS) are revolutionizing how industries store and manage energy. By converting electrical energy into rotational kinetic energy, these systems provide rapid response times, high efficiency, and long lifespans. A rotating mass, ideally spinning in a vacuum. High-speed flywheels- made from composite materials like carbon fiber and fiberglas, typically operate at speeds between 20,000 and 60,000 revolutions per minute (RPM) and can. .
