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.
