What does kWh mean in flywheel energy storage system

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. . [PDF]
