The basis of the system is a flywheel, similar in appearance and concept to those used in mechanical hybrid systems. The difference is that the flywheel in the EM system is ''loaded'' or ''doped'' with magnetic particulates that can be magnetised in certain directions. What we have in effect is a large conventional electric motor rotor
Vice versa, the flywheel is slowed down when demand increases, releasing more kinetic energy for the grid to convert into electricity. In Shanxi Province''s city of Changzhi, a project to construct China''s first grid-level flywheel energy storage facility began in June this year. Backed by Shenzhen Energy Group, the project''s main investor
Examples of flywheels optimized for vehicular applications were found with a specific power of 5.5 kW/kg and a specific energy of 3.5 Wh/kg. Another flywheel system had 3.15 kW/kg and 6.4 Wh/kg
Figure 1 – Typical Flywheel Electrical Interface. Unlike a battery, which stores energy chemically, the FESS stores energy in rotational kinetic form. To charge the flywheel, current is delivered to the motor, which spins up the rotor. When the rotor reaches full speed, the FESS is fully. Report Documentation Page.

Abstract: This article presents crucial issues regarding the design, manufacture, and testing of a steel rotor for a 0.5-kWh flywheel energy storage system. A prototype was built
The differences in the TIC of the two systems are due to differences in rotor and bearing costs. The composite rotor flywheel energy storage system costs more than the steel rotor flywheel energy storage system because composite materials are still in the research and development stage and material and manufacturing costs are high.
