YunChen Shen(Jenny) SCI-220 Timothy Brecheen Review of the Flywheel Energy Storage Flywheel energy storage (FES) works by accelerating a rotor ( flywheel ) to a very high speed and maintaining the energy in the system as rotational energy . When energy is extracting from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy , and adding energy to the system correspondingly results in an increase in the speed of the flywheel. The flywheel is a basic conceptual machine that takes advantage of the conservation of energy by storing energy in the form of rotational kinetic energy. A basic flywheel is a device that has a large moment of inertia and by spinning around only one axis is used to store rotational energy . Flywheel energy storage has been around for many years, but the traditional design uses heavy steel flywheels revolving at low speeds. Energy capacity is proportional to the weight and the square of the speed, leading power engineers to consider the
