Are flywheel energy storage systems feasible?
Vaal University of Technology, Vanderbijlpark, Sou th Africa. Abstract - This study gives a critical review of flywheel energy storage systems and their feasibility in various applications. Flywheel energy storage systems have gained increased popularity as a method of environmentally friendly energy storage.
How does a flywheel energy storage system work?
Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. For discharging, the motor acts as a generator, braking the rotor to produce electricity.
Are flywheel-based hybrid energy storage systems based on compressed air energy storage?
While many papers compare different ESS technologies, only a few research, studies design and control flywheel-based hybrid energy storage systems. Recently, Zhang et al. present a hybrid energy storage system based on compressed air energy storage and FESS.
What rotors are used in a grid-scale flywheel energy storage system?
While some systems use low mass/high speed rotors, other use very massive rotors eg 200 tonnes and correspondingly much lower rotational speeds, referred to as grid-scale flywheel energy storage.
