Overview

CycloKinetics builds a flywheel energy storage system to support a world with more renewable power. It stores energy as spinning kinetic energy in a rotor made entirely from carbon fiber, housed in a hubless design with an optimized magnetic bearing and power electronics to transfer energy in and out. The hubless carbon-fiber rotor and high-speed operation give higher energy density and lower costs than traditional flywheels and batteries, while reducing wear and environmental impact. The company’s approach focuses on cheaper, longer-lasting energy storage for grid use, especially to balance solar and wind power. Its goal is to help make 100% renewable energy possible by accelerating the transition away from fossil-fuel storage options.
