A flywheel can store energy thanks to the conservation of angular momentum. After the massive rotating element starts spinning and reaches its final velocity, in the absence of friction, it would spin indefinitely, even resisting changes in orientation and other external factors. [pdf]
[FAQS about How long can flywheel energy storage be stored ]
Energy Storage: The flywheel continues to spin at high speed, maintaining energy as long as friction and resistance are minimized. The longer it spins, the more energy it holds, similar to how the skater retains rotational energy as they keep spinning. [pdf]

Photo: A typical modern flywheel doesn't even look like a wheel! It consists of a spinning carbon-fiber cylinder mounted inside a very sturdy container, which is designed to stop any high-speed fragments if the rotor should break. Flywheels like this have an electric motor and/or. .
Flywheels are relatively simple technology withlots of plus points compared to rivals such as rechargeable batteries: in terms of initial cost and ongoingmaintenance, they work out cheaper, last about 10 times longer(there are still. - Limited energy storage time of around 15 minutes, making flywheels only suitable for quick, timely applications.
