A flywheel energy storage can have energy fed in the rotational mass of a flywheel, store it as kinetic energy, and release out upon demand. They work by spinning up a heavy disk or rotor to high speeds and then tapping that rotational energy to discharge high power bursts of electricity. It is difficult to use flywheels to store energy for ...

The flywheel size (4-foot/1.2m diameter) is perfectly optimized to fit a cluster of 10 units inside a 20-foot container. Cables run from each flywheel unit to the associated power electronics rack. Power Electronics racks are stored in an electrical cabinet. A DC bus of 585-715V links the units (650V nominal).
