We have commissioned external analysis to improve understanding of the role that large-scale, long-duration electricity storage will play in the electricity system, how much may be required at different points in time, and the benefits of different durations of storage. It includes a range of different technologies such as pumped hydro storage and less established long duration storage technologies like hydrogen storage and compressed air energy storage. This analysis will inform how we address the barriers to deployment that such storage faces. We aim to publish the results of this analysis in due course.
