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.
Therefore, the selection of appropriate rotor materials and the design of rotor structure are the key to reducing the cost of flywheel energy storage, which is crucial for the promotion of flywheel energy storage. Several review papers address different aspects of FESS research.
The performance of the energy storage flywheel is basically determined by the rotor material properties, geometry and rotating speed. A high density material can significantly increase the rotor mass and hence increase the stored kinetic energy of flywheel.
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.
