Flywheels as mechanical batteries. Flywheel Energy Storage (FES) is a relatively new concept that is being used to overcome the limitations of intermittent energy supplies, such as Solar PV or Wind Turbines that do not produce electricity 24/7. A flywheel energy storage system can be described as a mechanical battery, in that it does not create electricity, it simply converts and

Flywheel energy storage (FES) works by accelerating a rotor 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

Flywheels, one of the earliest forms of energy storage, could play a significant role in the transformation of the electrical power system into one that is fully sustainable yet low cost.
The principle of flywheel energy storage FESS technology originates from aerospace technology. Its working principle is based on the use of electricity as the driving force to drive the flywheel to rotate at a high speed and store electrical energy in the form of mechanical energy.
On a high level, flywheel energy storage systems have two major components: a rotor (i.e., flywheel) and an electric motor. These systems work by having the electric motor accelerate the rotor to high speeds, effectively converting the original electrical energy into a stored form of rotational energy (i.e., angular momentum).
However, the high cost of purchase and maintenance of solar batteries has been a major hindrance. Flywheel energy storage systems are suitable and economical when frequent charge and discharge cycles are required. Furthermore, flywheel batteries have high power density and a low environmental footprint.
Fly wheels store energy in mechanical rotational energy to be then converted into the required power form when required. Energy storage is a vital component of any power system, as the stored energy can be used to offset inconsistencies in the power delivery system.
Indeed, the development of high strength, low-density carbon fiber composites (CFCs) in the 1970s generated renewed interest in flywheel energy storage. Based on design strengths typically used in commercial flywheels, σ max /ρ is around 600 kNm/kg for CFC, whereas for wrought flywheel steels, it is around 75 kNm/kg.
