The main power circuit technology is mature, and the main research is the conversion control algorithm. China has successfully developed MW-class motor converters for flywheel energy storage systems. 4. FES System
Small-scale flywheel energy storage systems have relatively low specific energy figures once volume and weight of containment is comprised. But the high specific power possible, constrained only by the electrical machine and the power converter interface, makes this technology more suited for buffer storage applications.
Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage.
