From Tokyo's subway system to Texas wind farms, rotational energy storage now competes on both performance and price per kWh. Department of Energy confirms flywheels require 83% less rare earth materials than lithium batteries - a critical advantage amid supply. . Flywheel energy storage (FES) works by spinning a rotor (flywheel) and maintaining the energy in the system as rotational energy. Flywheels are best suited for applications that require high power, a large number of charge discharge cycles, and extremely long calendar life. Electrical energy is thus converted to kinetic energy for storage. At the core is the rotor – a cylindrical or disc-shaped mass that spins at high speed, often in excess of tens of thousands of. . As global industries seek cost-effective energy storage, flywheel systems emerge as game-changers with flywheel energy storage cost per kWh dropping 28% since 2020. Unlike lithium-ion batteries requiring frequent replacements, a California data center using 10MW flywheel array achieved $1,200/kWh. .
