Flywheel (named mechanical battery [10]) might be used as the most popular energy storage system and the oldest one [11]. Flywheel (FW) saves the kinetic
The flywheel energy storage system (FESS) converts the electric energy into kinetic energy when the speed is increased by the two-way motor and the opposite when reduced. The energy storage capacity depends on the inertia and maximum speed of the rotor. In order to meet the frequency modulation needs of the power grid and reduce

Disadvantages of Flywheel Energy Storage. High initial cost – Setting up a flywheel system can be expensive due to the cost of materials and sophisticated technology needed. Limited energy capacity – The amount of energy a flywheel can store is not very big, so it might not be enough for large-scale use. Requires regular maintenance
This high-speed FESS stores 2.8 kWh energy, and can keep a 100-W light on for 24 hours. Some FESS design considerations such as cooling system, vacuum pump, and housing will be simplified since the ISS is situated in a vacuum space. In addition to storing energy, the flywheel in the ISS can be used in navigation.
A review of energy storage types, applications and recent developments. S. Koohi-Fayegh, M.A. Rosen, in Journal of Energy Storage, 2020 2.4 Flywheel energy storage.

Moreover, flywheel energy storage system array (FESA) is a potential and promising alternative to other forms of ESS in power system applications for improving power system efficiency, stability and security [29]. However, control systems of
These are: • In the absence of smooth continuous energy, to provide continuous smooth energy. For example, in reciprocating motors, flywheels are used because the torque produced by the motor is discontinuous. • A flywheel is used to store energy and then release it. In some cases, energy is released at a speed that the energy source cannot.

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
