Equipment cost distribution for the flywheel energy storage systems. FESSs are used for short-duration power applications. Therefore, power capital cost ($/kW) could be a useful parameter to compare the economic feasibility of energy storage systems for similar power applications.
Typical energies stored in a single unit range from less than a kilowatt-hour to levels approaching 150 kilowatt-hours. Thus, a single composite flywheel can be equivalent, in stored energy, from one to more than 100 automotive batteries. Moreover, in flywheel systems, the stored energy and output power are relatively independent of each other.
Composite flywheels are designed, constructed, and used for energy storage applications, particularly those in which energy density is an important factor. Typical energies stored in a single unit range from less than a kilowatt-hour to levels approaching 150 kilowatt-hours.
