What is a flywheel energy storage system?

A flywheel energy storage system is a mechanical device used to store energy through rotational motion. When excess electricity is available, it is used to accelerate a flywheel to a very high speed. The energy is stored as kinetic energy and can be retrieved by slowing down the flywheel, converting the motion back into electricity.

Could flywheels be the future of energy storage?

Flywheels, one of the earliest forms of energy storage, could play a significant role in the transformation of the electri-cal power system into one that is fully sustainable yet low cost.

What is a Flywheel Energy Storage System (FESS)?

A Flywheel Energy Storage System (FESS) is defined as a system that stores energy for a distinct period of time to be retrieved later. There is a class distinction between flywheels used for smoothing the intermittent output of an engine or load on a machine and these energy storage systems.

What is the difference between a flywheel and a battery storage system?

Flywheel Systems are more suited for applications that require rapid energy bursts, such as power grid stabilization, frequency regulation, and backup power for critical infrastructure. Battery Storage is typically a better choice for long-term energy storage, such as for renewable energy systems (solar or wind) or home energy storage.

How much energy is stored in a vehicle mounted flywheel system?

The energy stored in a vehicle-mounted flywheel system is typically low, being of similar magnitude to the kinetic energy of the vehicle operating at a moderate speed.

What is China's largest flywheel energy storage plant?

China's massive 30-megawatt (MW) flywheel energy storage plant, the Dinglun power station, is now connected to the grid, making it the largest operational flywheel energy storage facility ever built.
