Energy storage projects boosted by Government funding

Case Studies

Five UK based energy storage projects have been awarded over £32m of Government funding to help support the UK’s transition to a clean energy society.

Energy storage technologies are essential if the country is to decarbonise its energy supply, storing excess energy produced by renewable energy systems such as wind, solar and hydropower for use when required, reducing fossil fuel use, boosting our security of supply and increasing the resilience of the UK’s electricity grid. 

The £32.9m funding has been made available as part of phase two of the Longer Duration Energy Storage (LODES) competition, to develop technologies that can store energy as heat, electricity or as a low-carbon energy carrier like hydrogen.

Minister for Climate Graham Stuart said:

“Accelerating renewables is key to boosting our energy resilience. Energy storage helps us get the full benefit of these renewables, improving efficiency and helping drive down costs in the long term.

“This £32.9 million government backing will enable green innovators across the UK to develop this technology, helping create new jobs and encouraging private investment, while also safeguarding the UK’s energy security.”

Phase one of the LODES competition saw 19 projects awarded a share of £2.7m to demonstrate the capability of the technologies in question. Of these the following five projects, chosen as the most promising, have been awarded funding via phase 2, to build prototypes and demonstrators: 

  • StorTera Ltd, based in Edinburgh, will receive over £5m to develop a long-lasting megawatt scale battery that can operate for up to eight hours. The company’s ‘single liquid flow battery (SLIQ)’ will reportedly offer flexibility to the grid by storing electricity which can then be released when weather dependent technologies such as wind turbines and solar panels have periods of decreased energy generation.
  • RheEnergise Ltd have been awarded over £8m to build a demonstrator of their High-Density Hydro® storage system, featuring a fluid, 2½ times denser than water, that can create 2½ times the electricity from gentle slopes when compared to conventional hydro-power systems.
  • Sunamp will receive £9m of funding to trial their advanced thermal storage system in 100 homes across the UK. 
  • The University of Sheffield will receive £2.6m to develop a prototype modular thermal energy storage system, enabling optimised, flexible storage of heat within homes, providing benefits for both the occupant and the grid.
  • EDF UK, in partnership with the University of Bristol, Urenco and the UK Atomic Energy Authority (UKAEA), will receive £7.73m to develop a hydrogen storage demonstrator utilising depleted uranium at UKAEA’s Culham Science Centre in Abingdon, Oxfordshire. Electricity will be converted to hydrogen via electrolysis and stored for future use – either directly as hydrogen, or converted back to electricity via a fuel cell when required.
