The superconducting energy storage flywheel comprising of mag-netic and superconducting bearings is fit for energy storage on account of its high efficiency, long cycle life, wide operating temperature range and so on.
The flywheel comprising of magnetic and supercon-ducting bearings is fit for energy storage. Supercon-ducting energy storage flywheel can be used in space for energy storage, attitude control for satellites.
Accordingly, there are two main types of high-temperature superconducting energy storage flywheels, and if a system comprising both the thrust bearing and the radial bearing will have the characteristics of both types of bearings.
Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage. The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage.
