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

The housing of a flywheel energy storage system (FESS) also serves as a burst containment in the case of rotor failure of vehicle crash. In this chapter, the requirements for this safety-critical component are discussed, followed by an analysis of historical and contemporary burst containment designs. By providing several practical
(1) E F W = 1 2 J ω 2 Where, E FW is the stored energy in the flywheel and J and ω are moment of inertia and angular velocity of rotor, respectively. As it can be seen in (1), in order to increase stored energy of flywheel, two solutions exist: increasing in flywheel speed or its inertia.The moment of the inertia depends on shape and mass of
In flywheel energy storage systems, carbon fibres are typically used in the construction of the flywheel itself. They are wound into a cylindrical shape and then coated with a resin to hold the fibres in place. The flywheel is then placed in a vacuum-sealed container to reduce friction and increase efficiency.
With this FESS, 66% of the brake energy can be stored and reused in the best conditions. In vehicles, a flywheel is specifically weighted to the vehicle''s crankshaft to smooth out the rough feeling and to save energy. In city buses and intercity taxis, it can have a huge impact on reducing fuel consumption.
