It allows for time-shifting power, charging from solar, providing grid support, and exporting power back to the grid. When an ESS system is able to produce more power than it can use and store, it can sell the surplus to the grid; and when it has insufficient energy or power, it automatically buys it from the grid.

flywheel, heavy wheel attached to a rotating shaft so as to smooth out delivery of power from a motor to a machine. The inertia of the flywheel opposes and moderates fluctuations in the speed of the engine and stores the excess energy for intermittent use. To oppose speed fluctuations effectively, a flywheel is given a high rotational inertia
Electrochemical capacitors. ECs, which are also called supercapacitors, are of two kinds, based on their various mechanisms of energy storage, that is, EDLCs and pseudocapacitors. EDLCs initially store charges in double electrical layers formed near the electrode/electrolyte interfaces, as shown in Fig. 2.1.

Energy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential, electricity, elevated temperature, latent heat and kinetic. Ene
