Abstract - This study gives a critical review of flywheel energy storage systems and their feasibility in various applications. Flywheel energy storage systems have gained increased popularity as a method of environmentally friendly energy storage.
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.
The flywheel energy storage system mainly stores energy through the inertia of the high-speed rotation of the rotor. In order to fully utilize material strength to achieve higher energy storage density, rotors are increasingly operating at extremely high flange speeds.
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.
In 1999 , the University of Texas at Austin developed a 7-ring interference assembled composite material flywheel energy storage system and provided a stress distribution calculation method for the flywheel energy storage system.
The German company Piller has launched a flywheel energy storage unit for dynamic UPS power systems, with a power of 3 MW and energy storage of 60 MJ. It uses a high-quality metal flywheel and a high-power synchronous excitation motor.
