A typical system consists of a flywheel supported by connected to a . The flywheel and sometimes motor–generator may be enclosed in a to reduce friction and energy loss. First-generation flywheel energy-storage systems use a large flywheel rotating on mechanical bearings. Newer systems use composite The lithium-ion battery has a high energy density, lower cost per energy capacity but much less power density, and high cost per power capacity. This explains its popularity in applications that require high energy capacities and are weight-sensitive, such as automotive and consumer. .

Flywheel energy storage is mostly used in hybrid systems that complement solar and wind energyby enhancing their stability and balancing the grid frequency because of their quicker response times or with high-energy density storage solutions like Li-ion batteries . Can flywheels be used for power. .
Flywheel energy storage (FES) works by spinning a rotor (flywheel) and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the. .

Currently, the most widely used energy storage system is the chemical battery. However, chemical batteries have several shortcomings, such as high cost, low thermal reliability, short life cycles and high maintenance costs. Furthermore, chemical batteries cannot provide high power in a short time. .
Flywheel energy storage (also referred to as FES) works by accelerating a flywheel (rotor) to a really high speed and maintaining this energy within the system as rotational energy. When the stored energy is extracted from the storage system, the rotational speed of the flywheel is reduced as a. .
Environmentally Friendly: Since there are no harmful chemicals or heavy metals involved, flywheels are considered a greener option compared to chemical batteries. While both flywheel and battery storage systems serve the same fundamental purpose—storing energy for later use—their technologies.
