Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of th

I think you might be over-estimating how much energy these things can store.
How do you calculate the energy of a flywheel?
George Jackson. Published: May 4, 2023. Sharing is Caring. Kinetic Energy goes as 1/2*I*w2. For flywheels I =1/2MR2. If we measure w in revolutions per second then the stored energy of a flywheel is approximately 6MR2 x w2 (RPS) For M=140 kg and R=50cm this yields a required w of 500 RPS or 30,000 RPM.

Flywheel Energy Storage
This results in the storage of kinetic energy. When energy is required, the motor functions as a generator, because the flywheel transfers rotational energy to it. This is converted back into electrical energy, thus completing the cycle. As the flywheel spins faster, it experiences greater force and thus stores more energy.
