The length of energy storage technologies is divided into two categories: LDES systems can discharge power for many hours to days or even longer, while short-duration storage systems usually remove for a few minutes to a few hours. It is impossible to exaggerate the significance of LDES in reaching net zero.
Against the backdrop of swift and significant cost reductions, the use of battery energy storage in power systems is increasing. Not that energy storage is a new phenomenon: pumped hydro-storage has seen widespread deployment for decades. There is, however, no doubt we are entering a new phase full of potential and opportunities.

Power capacity is the maximum amount how much electric power an energy storage system can charge or deliver in megawatts (MW), while duration is how long it can do so in hours. A megawatt-hour (MWh) is typically the unit used to describe the amount of energy a battery can store, in megawatts multiplied by hours.
