Since the Space Station will spend approximately one-third of its orbital time in the Earth's shadow, energy storage for this dark period will be a significant design driver. Because of this, highly efficient energy storage devices such as those of the inertial type, better known as flywheels, are particularly attractive for these applications. Their high efficiency, coupled with the added advantages of long life, light weight, design flexibility, and readily monitored depth-of-discharge, make them prime candidates for a wide variety of large and small applications. This paper describes various inertial energy storage concepts and discusses the relative merits of each. Important design parameters such as energy density, depth-of-discharge,and turnaround efficiency are discussed along with their influence on system design. An assessment is made of three critical technology areas: rotor materials, magnetic suspension, and motor-generators. Conclusions on the viability of inertial energy storage systems are presented. Finally, recommendations are made for areas of further work in flywheel technology.
