What is a flywheel energy storage system?
A typical system consists of a flywheel supported by rolling-element bearing connected to a motor–generator. The flywheel and sometimes motor–generator may be enclosed in a vacuum chamber to reduce friction and energy loss. First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings.
What are flywheels used for?
Flywheels are used as intermediate energy storage systems for transport applications such as automobiles. Flywheel storage energy systems are more commonly used in Formula 1 cars and hybrid vehicles. However, manufacturers such as Maruti Suzuki have adopted this technology for passenger vehicles also.
What are large synchronous flywheels used for?
Large synchronous flywheels are also used for energy storage, yet not to be mistaken with FESS. They use very large flywheels with a mass in the order of 100 tonnes. These are directly connected to a synchronous condenser in order to provide grid inertia.
What are the limitations of Flywheel design?
One of the primary limits to flywheel design is the tensile strength of the rotor. Generally speaking, the stronger the disc, the faster it may be spun, and the more energy the system can store.
