Flywheels excel in short-duration storage applications, typically less than four hours. This is precisely the time window needed to bridge the gap between when solar generation begins to drop and when peak demand occurs in the early evening. 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. . Flywheels don't store energy in "degrees" but in kilowatt-hours (kWh) or megajoules (MJ). Think of them as spinning batteries – the faster and heavier they rotate, the more energy they hold. Modern industrial flywheels can store anywhere from 5 kWh to 133 kWh, with some advanced models reaching up. . Flywheel energy storage works by storing energy kinetically in a rotating flywheel. This makes them ideal for solar. .
