Is it again time for the flywheel-based energy storage systems?

A brief background: the underlying principle of the flywheel energy storage system—often called the FES system or FESS—is a long-established basic physics. Use the available energy to spin up a rotor wheel (gyro) via a motor/generator (M/G), which stores the energy in the rotating mass (Figure 1). Electronics is also required for the motor

Spinning Batteries

Flywheels are an alternative to deep cycle batteries or molten salt for storing energy that can be transformed into electricity. Flywheel energy storage works by accelerating a rotor (flywheel) to incredibly high speeds and maintaining the energy in the system as rotational energy, which is converted back by slowing down the flywheel.
