The UK is advancing long-duration energy storage (LDES) technologies to store renewable energy for extended periods, with Ofgem supporting 16 projects through a new cap-and-floor scheme. These technologies aim to stabilise supply during low wind and solar periods and could reduce energy system costs by over £24bn between 2030 and 2050.

◆ ◆ The Wire takeaway
You must now factor in long-duration storage options as prime energy system enablers. UK policy support opens projects that will change grid reliability and create procurement opportunities in storage tech over the next decade.
