Energy storage in uk

Does Great Britain need large-scale electricity storage?

It draws on studies from around the world but is focussed on the need for large-scale electrical energy storage in Great Britaina (GB) and how, and at what cost, storage needs might best be met. In 2050 Great Britain’s demand for electricity could be met by wind and solar energy supported by large-scale storage.

Can a large-scale storage system meet Britain's electricity demand?

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.

How much energy storage is installed in the UK?

Total installed capacity of utility-scale storage is now approaching 1.7 GW across 127 sites and the figure below shows annual installed energy storage capacity by project size. The UK installed 446 MW of utility-scale energy storage in 2021, close to the previous high seen back in 2018. Image: Solar Media Market Research.

How can electricity be stored?

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.

What is 'large-scale electricity storage'?

The report, ‘Large-scale electricity storage’, published today, examines a wide variety of ways to store surplus wind and solar generated electricity - including green hydrogen, advanced compressed air energy storage (ACAES), ammonia, and heat - which will be needed when Great Britain’s supply is dominated by volatile wind and solar power.

How did energy storage growth in the UK perform in 2021?

Utility-scale energy storage activity in the UK saw strong growth during 2021 with annual deployment growing 70% compared to 2020. Additionally, the pipeline of future projects increased by 11 GW to over 27 GW by the end of 2021.
