Large-scale energy storage is so-named to distinguish it from small-scale energy storage (e.g., batteries, capacitors, and small energy tanks). The advantages of large-scale energy storage are its capacity to accommodate many energy carriers, its high security over decades of service time, and its acceptable construction and economic management.
Large scale storage of heat is critical for the successful decarbonisation of the UK''s energy mix and for grid-balancing.

Large-scale and long-duration electricity storage could provide an important role in decarbonising our energy system, for example by storing renewable power and discharging it over periods of low wind. However there is evidence that it faces market challenges that mean it may struggle to deploy at scale.
The technologies that are most suitable for grid-scale electricity storage are in the top right corner, with high powers and discharge times of hours or days (but not weeks or months). These are Pumped Hydropower, Hydrogen, Compressed air and Cryogenic Energy Storage (also known as 'Liquid Air Energy Storage' (LAES)).
There are a number of technologies that are likely to help deliver this capability (battery, pumped hydro, air-based etc) with battery energy storage systems (BESS) expected to be responsible for delivering the largest share of storage power capacity.
The REA sees energy storage as a key missing piece of the UK's energy policy. Storage can help deliver the low carbon energy the country needs and it is therefore vitally important that it is appropriately incentivised and supported.
No matter how much generating capacity is installed, there will be times when wind and solar cannot meet all demand, and large-scale storage will be needed. Historical weather records indicate that it will be necessary to store large amounts of energy (some 1000 times that provided by pumped hydro) for many years.
There are many applications for electricity storage: from rechargeable batteries in small appliances to large hydroelectric dams, used for grid-scale electricity storage. They differ in the amount of energy that has to be stored and the rate (power) at which it has to be transferred in and out of the storage system.
