Due to the variability of renewable electricity (wind, solar) and its lack of synchronicity with the peaks of electricity demand, there is an essential need to store electricity at times of excess supply, for use at times of high demand. This article reviews some of the key issues concerning electricity storage.
Electrical energy storage offers two other important advantages. First, it decouples electricity generation from the load or electricity user, thus making it easier to regulate supply and demand. Second, it allows distributed storage opportunities for local grids, or microgrids, which greatly improve grid security, and hence, energy security.
