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.
Do power utilities need a flywheel storage system?
Power utilities need innovative ways to store renewable wind and solar energy, during low demand periods, so they can release it after sunset when demand is high. Several innovative power utilities already use flywheel storage systems to maintain power grid frequency. Renewable energy is knocking on flywheel energy’s door.
Can a flywheel energy storage system stabilize a power grid?
Anything to do with energy storage attracts us, although a flywheel energy storage system is very different from a battery. Flywheels can store grid energy up to several tens of megawatts. If we had enough of them, we could use them to stabilize power grids.
Why is a flywheel considered a dynamic storage system?
Because a flywheel must be accelerated by an external force before it will store energy, it is considered a “dynamic” storage system. The rate at which the flywheel spins remains nearly constant because of the vacuum-like container, which prevents friction from slowing the revolution.
