Flywheel storage technology stores energy as the kinetic energy of a rapidly spinning rotor. This form of mechanical energy storage can provide near-instantaneous response and is capable of millions of cycles.
Flywheel storage addresses the need for fast-response and high-cycle-count energy storage solutions, particularly for grid stability and frequency regulation.
Energy from an external power source is used to spin up a heavy, vacuum-sealed rotor on magnetic bearings. When energy is needed, the spinning rotor drives a generator, converting its kinetic energy back into electrical energy with minimal losses.
The manufacturing process involves creating a robust vacuum-sealed housing, precise machining of the rotor, and installation of magnetic bearings to ensure minimal friction losses. The rotor is typically made from high-strength materials like steel or composite alloys.
Components are fabricated, assembled in a clean room environment to prevent contamination, and tested for performance before integration into a storage system.
