HOW DO FLYWHEEL ENERGY STORAGE SYSTEMS WORK?

Flywheel energy storage systems operate based on the principles of kinetic energy storage. The underlying mechanism involves converting electrical energy into kinetic energy through the rotation of a mass (flywheel) stored within a vacuum chamber. This creates minimal friction, allowing the flywheel to spin at extremely high speeds without significant energy loss.

During energy charging, electricity powers an electric motor that accelerates the flywheel. The kinetic energy generated during this process can be stored until needed. When energy demand increases, the flywheel will decelerate, enabling the motor to act as a generator and convert kinetic energy back into electrical energy. This fast response time makes flywheel systems particularly effective in applications requiring high power density.

Moreover, advanced flywheel designs incorporate sophisticated control systems that allow for real-time adjustments to energy output, optimizing performance based on grid conditions.
