Mechanical energy storage can be added to many types of systems that use heat, water or air with compressors, turbines, and other machinery, providing an alternative to battery storage, and enabling clean power to be stored for days. . Compressed air energy storage (CAES) plants are largely equivalent to pumped-hydro power plants in terms of their applications. But,. . Two existing commercial scale CAES plants in Huntorf, Germany, and in McIntosh, Alabama, USA, as well as all the proposed designs foreseeable future are based on the diabatic method. In principle, these plants are essentially just conventional gas turbines, but where the compression. . Much higher efficiencies of up to 70% can be achieved if the heat of compression is recovered and used to reheat the compressed air during turbine operations because there is no. . Independent of the selected method, very large volume storage sites are required because of the low storage density. Preferable locations are.

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 system correspondingly results in an. . A typical system consists of a flywheel supported by connected to a . The flywheel and sometimes. . GeneralCompared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no. . Flywheels are not as adversely affected by temperature changes, can operate at a much wider temperature range, and are not subject to many of the common failures of chemical . They are also less potentially damaging to the environment, being largely made of . • • • .
