Flywheel Energy Storage Explained

For a flywheel, this depends on both the amount of mass it has and how that mass is spread out around its spinning axis. If you add more mass to the flywheel, you increase its moment of inertia. This means the flywheel can store more energy at the same speed. So, a heavier flywheel can hold more energy and deliver more power when needed.

Is a flywheel a battery? : r/ElectricalEngineering

With a cap, or a flywheel, you don''t need that extra piece. A flywheel, you put rotational energy in, it''s stored as rotational energy. A cap, you put electrons in, that charge is directly stored. An inductor, you put electrons in, but they need to be converted to an electric field. The analogy was a flywheel, not a hydraulic system.

A typical system consists of a flywheel supported by rolling-element bearing connected to a motor–generator. The flywheel and sometimes motor–generator may be enclosed in a vacuum chamber to reduce friction and energy loss. First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors

DIY Flywheel Energy Storage on a small scale? : r/AskEngineers

Generator flywheel and diesel were on one axis with a coupling towards the diesel. The flywheel was constructed as an engine around that axis, so the stator is the axis at 1500 rpm and the flywheel turns around at max. 4400 rpm. If energy needs to be provided, the outer rotor is slowed down by a brake in that axis, so the energy is transferred

Thus; kinetic (mechanical) energy is stored in the flywheel. Then, by using the motor as a generator the kinetic energy in the flywheel can be converted back into electrical energy, and re-stored in the battery as chemical energy. The energy stored in the flywheel equates to the electrical energy taken from the battery minus the energy lost as
