Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. 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 th
The Status and Future of Flywheel Energy Storage
This concise treatise on electric flywheel energy storage describes the fundamentals underpinning the technology and system elements. Steel and composite rotors are compared, including geometric effects and not
Compressed air, flywheels and more: Energy storage
Power is stored as kinetic energy by using a motor to accelerate the flywheels, and energy can be discharged by reversing the process so the flywheel drives a motor or some other electrical...
