The flywheel is the main energy storage component in the flywheel energy storage system, and it can only achieve high energy storage density when rotating at high speeds. Choosing appropriate flywheel body materials and structural shapes can improve the storage capacity and reliability of the flywheel.
The small energy storage composite flywheel of American company Powerthu can operate at 53000 rpm and store 0.53 kWh of energy . The superconducting flywheel energy storage system developed by the Japan Railway Technology Research Institute has a rotational speed of 6000 rpm and a single unit energy storage capacity of 100 kW·h.
A flywheel plays an important role in storing energy in modern machine systems. Flywheels can store rotational energy at a high rotating speed and have the ability to deliver a high output power if the system needs a stored energy to overcome a sudden loading or keep rotating for an expected long time.
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.
Flywheel energy storage systems are suitable and economical when frequent charge and discharge cycles are required. Furthermore, flywheel batteries have high power density and a
