Revterra stores energy in the motion of a flywheel. Electric energy is converted into kinetic energy by a spinning rotor. When needed, that kinetic energy is converted back to electricity. Revterra''s innovative approach leverages passively stable magnetic bearings and low-cost steel alloys to improve efficiency and reduce cost.

Energy storage flywheels are usually supported by active magnetic bearing (AMB) systems to avoid friction loss. Therefore, it can store energy at high efficiency over a long duration. Although it was estimated in [3] that after 2030, li-ion batteries would be more cost-competitive than any alternative for most applications.

In energy storage, the principle of the flywheel can be used. Flywheels store energy in the form of the angular momentum of a spinning mass, called a rotor. The work done to spin the mass is stored in the form of kinetic energy. Video 1 is a simple video that illustrates the concept of flywheel electrical energy storage.

A second class of distinction is the means by which energy is transmitted to and from the flywheel rotor. In a FESS, this is more commonly done by means of an electrical machine directly coupled to the flywheel rotor. This configuration, shown in Fig. 11.1, is particularly attractive due to its simplicity if electrical energy storage is needed.
