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.
A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.
Electricity can be stored in a variety of ways, including in batteries, by compressing air, by making hydrogen using electrolysers, or as heat. Storing hydrogen in solution-mined salt caverns will be the best way to meet the long-term storage need as it has the lowest cost per unit of energy storage capacity.
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. What electricity storage will be needed, and what are the alternatives?
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.
Great Britain’s demand for electricity could be met largely (or even wholly) by wind and solar energy supported by large-scale storage at a cost that compares favourably with the costs of low-carbon alternatives, which are not well suited to complementing intermittent wind and solar energy and variable demand.
