The use and role of flywheel energy storage systems
Flywheels, in short, are machines that store kinetic energy in a rotating mass. The flywheel operates via a “flywheel effect”whereby its rotation is maintained via its own inertia [1]. Although ancient science did not understand the mechanics of flywheels, ancient engineers were able to develop spindle whorls (by 6000 BC) and potter's wheels (by 3000 BC) which both used their own inertia to maintain motion [1]. Work on flywheels gradually expanded until the industrial revolution, whereby they were incorporated into engine design to smooth rotations and damp vibrations [1-3]. Early uses of flywheels in electrical systems included regulation of power generation systems [4] and damping vibrations [2, 3]; roles they continue in today [5]. However, flywheels have seen additional use as a form of battery and interest is increasing in this use as material developments are made.
