Ofgem advances long duration storage project

Ofgem has announced 16 long duration electricity storage (LDES) projects have been provisionally selected to receive support under its cap and floor scheme.

The regulator said the decisions marks a significant step forward in the development of LDES which should reduce costs by alleviating pressure on transmission and distribution networks.

The selected projects include pumped storage hydro, compressed air energy storage (CAES), lithium-ion batteries and vanadium redox flow batteries.

Akshay Kaul, Director General for Infrastructure at Ofgem, said: “It’s fantastic to see such a wide range of technologies coming forward.

“This takes us a step closer towards the long-duration energy storage we need in a clean power system to maintain secure supply during periods of cold, hot, still or cloudy weather when solar or wind power output may be low.”
