The ability to store energy over extended periods could help to deliver a secure and flexible energy system at reduced costs. A range of new technologies is being developed that includes compressed air, flow batteries, power-to-X processes, gravity energy storage and thermal energy storage. The Government is currently consulting on the potential of large-scale, long-duration electricity storage. They have also invested £6.7 million in a demonstration programme for innovative longer duration energy storage projects. Understanding the potential of energy storage to operate beyond the short term will be critical in determining the transition pathway the UK’s energy system might follow. This POSTnote will assess the various types of long duration energy storage currently being developed and their potential to contribute to the UK’s net zero goal.

Work on this briefing will commence in September 2022.
