Stream 1 aims to accelerate commercialisation of innovative longer duration energy storage projects through to actual demonstrations. During Phase 1, projects will be expected to mobilise their proposed technologies to prepare for potential deployment on the UK energy system.
The following 5 projects received funding for Stream 1, Phase 1.
Thermal energy storage
No projects were awarded funding through the Thermal energy storage technology category.
Power-to-X energy storage
Project Name: Ballylumford Power-to-X
Led by: B9 Energy Storage
Project Location: Ballylumford, Northern Ireland
B9 Energy Storage will receive £986,082 to mobilise a 20MW membrane free electrolyser green hydrogen project. Using otherwise curtailed wind power, hydrogen produced will be stored in local underground salt caverns for later use as a fuel in transport and electricity sectors, creating a full-cycle hydrogen economy (production, storage, distribution and usage) on site.
Electrical energy storage
Project name: GraviSTORE
Led by: Gravitricity
Project location: Northern England
Gravitricity Limited will receive £912,410.84 to design their multiweight energy store demonstrator project, which will store and discharge energy by lifting and lowering multiple weights in a vertical underground shaft.
Project name: Long Duration Offshore Storage Bundle
Led by: Subsea 7 Limited
Project location: Aberdeen, Scotland
Subsea 7 Limited and FLASC B.V. will receive £471,760.00 to further develop the Long Duration Offshore Storage Bundle which will store energy as a combination of pressurised seawater and compressed air, using an innovative hydro-pneumatic technology.
Project Name: Vanadium Flow Battery Longer Duration Energy Asset Demonstrator
Led by: Invinity Energy Systems
Project Location: Bathgate, Scotland
Invinity Energy Systems will receive £708,371 to demonstrate how a 40 MWh Vanadium Flow Battery could deliver long duration storage-enabled power on demand from UK-based solar generation.
Project Name: Cheshire Energy Storage Centre
Led by: io consulting
Project Location: Cheshire, UK
io consulting will receive £1 million to enable its consortium to develop an electricity storage facility which could use mothballed EDF gas cavities in Cheshire utilising Hydrostor’s Advanced Compressed Air Energy Storage technology.
