The cost of FES can be broken down into several components: Capital Expenditure (CapEx): The upfront cost of purchasing and installing the flywheel system. Operating Expenditure (OpEx): The recurring costs associated with maintaining and operating the FES, including energy losses and maintenance.Are flywheel energy storage systems economically feasible?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.
Does a flywheel storage system need a bottom-up research?However, almost no bottom-up research has been done, i.e., research that considers the technical parameters to size the components of a flywheel storage system, estimate cost parameters based on the design, and provide a probable distribution of the total investment cost and levelized cost of storage.
How much does a steel rotor flywheel cost?The steel rotor flywheel has a lower capital cost and levelized cost of storage. The costs of composite and steel rotor flywheels are $190 and $146/MWh, respectively. Flywheel energy storage systems are increasingly being considered as a promising alternative to electro-chemical batteries for short-duration utility applications.
What is the power rating of a flywheel energy storage system?Utility-scale energy storage systems for stationary applications typically have power ratings of 1 MW or more . The largest flywheel energy storage is in New York, USA by Beacon Power with a power rating of 20 MW and 15 min discharge duration .
How many flywheels are required?The corresponding number of flywheels required was calculated to be 200 and 186 (see Table 1). The TIC comprises total equipment cost, miscellaneous items cost, construction and commissioning cost, and contingency cost. The TEC, which comprises the costs of different components of the system, alone contributes about 68% to the TIC.
How much does a flywheel power converter cost?The costs of a power converter for composite and steel flywheels are $49,618 and $52,595, respectively. The cost difference is due to the difference in rated power, 100 kW for the composite flywheel and 108 kW for the steel flywheel. Fig. 5.
