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.
When is excess electricity stored in flywheels?
At times when there is more electricity supply than demand, such as during the night or on the weekend, power plants can feed their excess energy into huge flywheels, which will store it for periods ranging from minutes to hours and release it again at times of peak need.
