What is the unit of flywheel energy storage

Could Flywheels Be the Future of Energy Storage?

On a high level, flywheel energy storage systems have two major components: a rotor (i.e., flywheel) and an electric motor. These systems work by having the electric motor accelerate the rotor to high speeds, effectively converting the original electrical energy into a stored form of rotational energy (i.e., angular momentum).
