FAQs 6

How does a flywheel energy storage system work?

Flywheel energy storage uses electric motors to drive the flywheel to rotate at a high speed so that the electrical power is transformed into mechanical power and stored, and when necessary, flywheels drive generators to generate power. The flywheel system operates in the high vacuum environment.

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 long does a flywheel energy storage system last?

Flywheel energy storage systems have a long working life if periodically maintained (>25 years). The cycle numbers of flywheel energy storage systems are very high (>100,000). In addition, this storage technology is not affected by weather and climatic conditions . One of the most important issues of flywheel energy storage systems is safety.

How kinetic energy is stored in a flywheel?

In this storage scheme, kinetic energy is stored by spinning a disk or rotor about its axis. Amount of energy stored in disk or rotor is directly proportional to the square of the wheel speed and rotor׳s mass moment of inertia. Whenever power is required, flywheel uses the rotor inertia and converts stored kinetic energy into electricity .
