How does a flywheel store energy

WebFlywheels are used in most combustion piston engines. Energy is stored mechanically in a flywheel as kinetic energy. Kinetic Energy Kinetic energy in a flywheel can be expressed as Ef = 1/2 I ω2 (1) where Ef = flywheel kinetic energy (Nm, Joule, ft lb) I = moment of inertia (kg m2, lb ft2) ω = angular velocity ( rad /s) WebFlywheels 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.
