This paper provides an overview of a 100 kw flywheel capable of 100 kW-Hr energy storage that is being built by Vibration Control and Electromechanical Lab (VCEL) at Texas A&M University and Calnetix Technologies. The novel design has a potential of nearly doubling the energy density of conventional steel flywheels. Applications include renewable energy source energy storage, frequency regulation at power plants, regenerative braking on vehicles and cranes and backup power at data centers and hospitals. The design and construction of this Department of Energy sponsored flywheel will be presented.
