Flywheel energy storage (FES) is a kind of physics energy storage method exploiting a rotational block with kinetic energy that changes with the rotational speed varying [2, 3]. The speed-increasing flywheel stores energy when it is accelerated by a motor, which obtains electrical power from the grid through power electronic device driving.
Flywheels with the main attributes of high energy efficiency, and high power and energy density, compete with other storage technologies in electrical energy storage applications, as well as in transportation, military services, and space satellites .
Thanks to the unique advantages such as long life cycles, high power density, minimal environmental impact, and high power quality such as fast response and voltage stability, the flywheel/kinetic energy storage system (FESS) is gaining attention recently.
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.
