The idea with a flywheel for power storage is that a small amount of electricity is used to keep a heavy mass rotating at a very high speed — 10,000 revolutions per minute (rpm) or faster. Then when power interruptions happen or some extra power is needed to stabilize the grid, that flywheel generates power, gradually slowing down in …

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.
The core element of a flywheel consists of a rotating mass, typically axisymmetric, which stores rotary kinetic energy E according to. E = 12Iω2 [J], E = 1 2 I ω 2 [ J], (Equation 1) where E is the stored kinetic energy, I is the flywheel moment of inertia [kgm 2 ], and ω is the angular speed [rad/s]. In order to facilitate storage and ...

In the 1950s, flywheel energy storage systems were employed in vehicles such as gyrobuses in Switzerland and Belgium and they could also replace conventional chemical batteries in electric vehicles. They have also been utilized in rail transport, in aircraft launching systems and by NASA in their G2 flywheel for spacecraft energy storage.
Flywheel Energy Storage Systems (FESS) are essentially composed of a few key components besides the flywheel and electric motor: bearings, an enclosure, and a power electronic converter. 8 FESS have bearings to support the rotor and resist against forces to maintain its position, which allows it to spin at high velocities.

2. A 1,000kg, 5m, 200RPM flywheel would store 685,567J of energy if it was shaped like a disc. That''s 0.19kWh of energy — enough to boil the water for about seven (7) cups of tea or run a typical airconditioner for about 10 minutes. I think you might be over-estimating how much energy these things can store.
