A flywheel is a mechanical device that uses the conservation of angular momentum to store rotational energy, a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed. In particular, assuming the flywheel''s moment of inertia is constant (i.e., a flywheel with fixed mass and second ...
Flywheel Energy Storage Explained
Share this post. Flywheel energy storage systems (FESS) are a great way to store and use energy. They work by spinning a wheel really fast to store energy, and then slowing it down to release that energy when needed. FESS are perfect for keeping the power grid steady, providing backup power and supporting renewable energy sources.
REVIEW OF FLYWHEEL ENERGY STORAGE SYSTEM
Generally, the flywheel rotor is composed of the shaft, hub and rim (Fig. 1). The rim is the main energy storage component. Since the flywheel stores kinetic energy, the energy capacity of a rotor has the relation with its rotating speed and material (eq.1). 1 2 2 EI= ω (1) Where, I is moment of inertial (determined by the material
