Flywheel energy storage can be compared to the battery in the same way. The flywheel energy storage system uses electrical energy and stores it in the form of kinetic energy. When energy
Flywheel Energy Storage Explained
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

6 FAQs about [How to brake after the flywheel stores energy]
How can flywheels be more competitive to batteries?
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage.
How does a flywheel system store energy?
A flywheel system stores energy mechanically in the form of kinetic energy by spinning a mass at high speed. Electrical inputs spin the flywheel rotor and keep it spinning until called upon to release the stored energy. The amount of energy available and its duration is controlled by the mass and speed of the flywheel.
Can a flywheel optimize braking energy recovery and acceleration?
A. Smith and K. R. Pullen present the optimization of a flywheel designed for braking energy recovery and acceleration for hybrid vehicles. The result is optimal flywheel size and depth-of-discharge for a particular vehicle to achieve a balance between high transmission efficiency and low system mass.

Can a flywheel reduce friction?
The same guy who built the flywheel bike decided to see if he could use a flywheel in place of batteries for energy storage, and he had a great idea to reduce friction. By using magnetic levitation, friction losses were very low, and he set up an alternator to be turned by the levitating flywheel.
What is the difference between a flywheel and a battery?
The physical arrangement of batteries can be designed to match a wide variety of configurations, whereas a flywheel at a minimum must occupy a certain area and volume, because the energy it stores is proportional to its rotational inertia and to the square of its rotational speed.
