What is flywheel energy storage?

Flywheel energy storage is a promising technology for replacing conventional lead acid batteries as energy storage systems. Most modern high-speed flywheel energy storage systems (FESS) consist of a huge rotating cylinder supported on a stator (the stationary part of a rotary system) by magnetically levitated bearings.

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.

Why do flywheel energy storage systems have a high speed?

There are losses due to air friction and bearing in flywheel energy storage systems. These cause energy losses with self-discharge in the flywheel energy storage system. The high speeds have been achieved in the rotating body with the developments in the field of composite materials.

How kinetic energy is stored in a flywheel?

Electric energy is supplied into flywheel energy storage systems (FESS) and stored as kinetic energy. Kinetic energy is defined as the “energy of motion,” in this situation, the motion of a rotating mass known as a rotor, rotates in a near-frictionless environment.

What is a flywheel energy storage system (fess)?

Think of it as a mechanical storage tool that converts electrical energy into mechanical energy for storage. This energy is stored in the form of rotational kinetic energy. Typically, the energy input to a Flywheel Energy Storage System (FESS) comes from an electrical source like the grid or any other electrical source.

What is the function of a flywheel?

The basic function of the flywheel is to convert the mechanical energy for the end-use application, which is electrical energy. For this conversion, an electromechanical machine is required which could be a motor/generator set. Generator and motor: When the kinetic energy is being stored, the motor is used to drive the flywheel.
