What is a flywheel-storage power system?
A flywheel-storage power system uses a flywheel for grid energy storage, (see Flywheel energy storage) and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to serve as a short-term compensation storage.

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.

Are flywheel energy storage systems feasible?
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.
How can flywheels be more competitive to batteries?
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage.
