Flywheel energy storage systems

Flywheel energy storage systems store energy by spinning a heavy rotor at high speeds inside a vacuum chamber to minimize friction. When energy is needed, the rotor's momentum is converted back into electricity using a generator. This method allows for rapid charging and discharging with high efficiency, making it ideal for balancing power grids, smoothing out fluctuations, or providing quick bursts of energy. The system is durable, environmentally friendly, and capable of thousands of cycles with minimal wear, providing a reliable way to store and release electrical energy efficiently.
