Could flywheels be the future of energy storage?

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.

What is a flywheel energy storage system?

Flywheel Energy Storage Systems are used in a wide range of applications, including grid-connected energy management and uninterruptible power supply. With the advancement of technology, the FESS application is undergoing rapid renovation.

How kinetic energy is stored in a flywheel?

Electric energy is supplied into flywheel energy storage systems (FESS) and stored as kinetic energy. Kinetic energy is defined as the “energy of motion,” in this situation, the motion of a rotating mass known as a rotor, rotates in a near-frictionless environment.

When did flywheel energy storage system start?

In the years between 1800 and 1950, traditional steel-made flywheel gained application areas in propulsion, smooth power drawn from electrical sources, road vehicles. Modern flywheel energy storage system (FESS) only began in the 1970’s.

How much energy does a flywheel store?

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, σmax /ρ is around 600 kNm/kg for CFC, whereas for wrought flywheel steels, it is around 75 kNm/kg.

How does a kinetic energy storage system work?

The system captures otherwise lost kinetic energy and stores it for later use, improving overall energy efficiency. However, this can also lead to an unusual driving dynamic that may not align with the expectations of drivers accustomed to conventional systems.
