A study by Imperial College London has found that 4500MW of new long duration pumped hydro storage could save up to £690m per year in energy system costs by 2050. The study, for pumped hydro with 90GWh of storage, is focused on the benefits of new long-duration pumped hydro storage in Scotland, as the current most established long-duration energy storage technology. It was commissioned by SSE Renewables via Imperial Consultants. The main benefit of long duration storage, compared to short duration batteries, is being able to continuously charge up the storage with excess renewables and also discharge power to the grid for several hours or days when wind and solar output is low.

PUMPED hydro storage schemes could cut the costs of operating the UK’s energy system by around £700m a year according to a study commissioned by SSE, which is working on plans for a bumper development in the Highlands. The Perth-based energy giant expects to be able to generate huge amounts of hydro-electricity at the Coire Glas plant from the movement of water between two reservoirs.
