Flywheel Energy Storage Systems (FESS) represent an innovative mechanical energy storage technology that stores kinetic energy by accelerating a rotor (flywheel) to very high speeds and maintaining the energy in the system as rotational energy. The technology offers numerous advantages, including high power density, long operational life, quick response time, and minimal environmental impact compared to chemical batteries. These systems are particularly valuable in applications requiring frequent charge-discharge cycles, such as grid stabilization, uninterruptible power supply (UPS) systems, and renewable energy integration. The technology's ability to provide instantaneous power delivery and its low maintenance requirements make it increasingly attractive for various industrial and commercial applications. Furthermore, its environmentally friendly nature, as it doesn't require harmful chemicals or rare earth materials, aligns well with global sustainability goals.

The flywheel energy storage market is estimated to be valued at USD 1.43 Billion in 2024 and is expected to reach USD 1.74 Billion by 2031, growing at a compound annual growth rate (CAGR) of 2.84% from 2024 to 2031.
