This document describes a flywheel energy storage system. It includes an introduction, block diagram, theory of operation, design, components, circuit diagram, advantages and disadvantages, and conclusion. . Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Since the inertial energy stored in a flywheel varies as the square of its rpm, it can discharge 90 percent of its maximum stored energy from maximum to minimum speed limits. For discharging, the motor acts a a generator, braking the rotor to produce elect s electrical energy into mechanical energy. . used on reducing energy consumption effectively.

Is battery storage better than Flywheel?
Battery Storage is typically a better choice for long-term energy storage, such as for renewable energy systems (solar or wind) or home energy storage. Flywheel technology is evolving, with several countries, including China, leading the way in large-scale flywheel installations.
How efficient are flywheels?
Modern flywheels can achieve round-trip efficiencies of 85–90%, comparable to advanced battery systems. Moreover, flywheels can store and release energy with minimal losses, particularly when used for short-duration storage (on the order of minutes to a few hours).
Why should you use a flywheel for solar power?
Moreover, flywheels can store and release energy with minimal losses, particularly when used for short-duration storage (on the order of minutes to a few hours). This makes them ideal for solar power applications where energy needs to be stored during the day and discharged in the evening.
