The excess could be stored in a variety of ways, for example electrochemically in batteries, gravitationally by pumping water into dams, mechanically by compressing air, chemically by making hydrogen, or as heat. This report considers the use of large-scale electricity storage when power is supplied predominantly by wind and solar.
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.
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.
In conventional power stations, the electricity that is fed into the grid is generated by synchronised rotating machinery, whose mechanical inertia provides stability and helps maintain a constant voltage and frequency. Wind and solar plants use power electronics to provide AC power to the grid.
What electricity storage will be needed, and what are the alternatives? Electricity can be stored in a variety of ways, including in batteries, by compressing air, by making hydrogen using electrolysers, or as heat.
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.
