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
