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.
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.
Are flywheel energy storage systems a good alternative to electro-chemical batteries?
Electro-chemical ESSs can be used in short-duration services, , but they suffer from a short lifetime and the need to dispose of toxic materials, . Flywheel energy storage systems (FESSs) are a promising alternative to electro-chemical batteries for short-duration support to the grid .
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 .
Like a savings account for the electric grid, energy storage neatly balances electricity supply and demand. When energy generation exceeds demand, energy storage systems can store that excess energy until electricity production drops and the energy can be deposited back to the power. . From large-scale solutions like pumped hydro and compressed air energy storage to distributed technologies such as batteries and hydrogen fuel cells, the role of storage is expanding beyond merely being a back-up: it is becoming an integral component of modern power systems. The first battery, Volta's cell, was developed in 1800. power grid in 2025 in our latest Preliminary Monthly Electric Generator Inventory report. This amount represents an almost 30% increase from 2024 when 48.
