The Status and Future of Flywheel Energy Storage:
This concise treatise on electric flywheel energy storage describes the fundamentals underpinning the technology and system elements. Steel and composite rotors are compared, including geometric
Energy and environmental footprints of flywheels for utility
A flywheel is a mechanical storage system that converts electricity to kinetic energy during charging and the kinetic energy back to electricity during discharge. Steel rotor FESSs are the most widely used FESSs, but recent developments in composite materials have encouraged manufacturers to produce composite rotor FESSs.
The development of a techno-economic model for the assessment
The differences in the TIC of the two systems are due to differences in rotor and bearing costs. The composite rotor flywheel energy storage system costs more than the steel rotor flywheel energy storage system because composite materials are still in the research and development stage and material and manufacturing costs are high.
