First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass. To reduce friction, magnetic bearings are sometimes used instead of mechanical bearings.
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.
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.
Inertia must be replaced in a decarbonised grid in order to ensure stability. A hybrid flywheel energy storage system is proposed that returns “real” inertia. Active power control is possible using a differential drive unit (DDU). Case study applications and comments on turnaround efficiency are presented.
This can be achieved by high power-density storage, such as a high-speed Flywheel Energy Storage System (FESS). It is shown that a variable-mass flywheel can effectively utilise the FESS useable capacity in most transients close to optimal. Novel variable capacities FESS is proposed by introducing Dual-Inertia FESS (DIFESS) for EVs.
