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.
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. Measure or maintain direction in navigation. In this application, the principle of conservation of angular momentum is used ( Meijneke et al., 2021 ). The disk (flywheel) is the main component of a FESS setup.
