WebProperties of several composite materials suitable for flywheel energy storage were investigated. Design and stress analysis were used to determine for each material, the maximum energy densities and shape factor of the flywheel. The materials identified based on the results from this study outperformed the boron/epoxy–graphite/epoxy combination. WebApr 25, 2024 · Flywheel rim contributes 92% of the flywheel effect and web contributes 8% of flywheel effect. Hence in this work evaluation of stresses in the steel rim and webs made up of different composite materials are studied using finite element method and results are validated by analytical calculations.
Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles of use), high specific energy (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The energy efficiency (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 kWh to 1…
