UK Aims for 1.2GW Long Duration Energy Storage by 2030 Amidst Growing Demand for Renewables
The UK is advancing towards its Clean Power 2030 goal, highlighting the need for 1.2GW of long duration energy storage (LDES) and 15GW by 2050. Battery Energy Storage Systems (BESS) are currently prevalent, but face challenges such as thermal runaway risks and limited lifecycles. The government has introduced a cap and floor scheme to promote LDES technologies including pumped storage hydro, compressed air energy storage, liquid air energy storage, and vanadium flow batteries, each offering unique advantages and challenges in energy storage.

The UK requires an additional 1.2GW of long duration energy storage (LDES) to meet its Clean Power 2030 target, with a further 15GW needed by 2050. Current reliance on lithium-ion Battery Energy Storage Systems (BESS) is facing challenges like safety risks and limited lifespan.
A government cap and floor scheme aims to support LDES technologies, which include pumped storage hydro (PSH), compressed air energy storage (CAES), liquid air energy storage (LAES), and vanadium flow batteries (VFBs). The world's first full LAES plant is under construction in Manchester, set to start operations in 2026. VFBs are gaining attention for their scalability and safety.
