Proposal for the Longer Duration Energy Storage Demonstration innovation competition
Fund Name: Proposal for the Longer Duration Energy Storage Demonstration innovation competition
Project Length: Phase 1 (Stream 1 and 2 combined): September 2021- August 2022. Phase 2 (Stream 1 and 2 combined): January 2022 - March 2025.
Project Value: Stream 1: £1m - £11m. Stream 2: £50,000 - £9.45m.
This competition is intended to accelerate commercialisation of innovative longer duration energy storage projects (i.e. excluding commercial solutions such as pumped hydro/lithium ion) at different technology readiness levels, through first-of-a-kind (FOAK) full-system prototypes or actual demonstrations. Longer duration storage (across days, weeks, and months) could help reduce the cost of meeting net zero by storing excess low carbon generation for longer periods of time – helping to manage variation in generation, such as extended periods of low wind. This could reduce the amount of fossil fuel and low carbon generation that would otherwise be needed and optimise the output from renewables (rather than paying to turn off generators when there is excess supply).
This competition is divided into two streams. Stream 1 will provide grant funding for projects with technology readiness levels that are over 6– aiming to demonstrate the capability of first-of-a-kind energy storage facilities through actual demonstrations in operational environments. Stream 2 will provide Small Business Research Initiative (SBRI) funding for projects with technology readiness levels that are either 4 or 5 – aiming to demonstrate first-of-a-kind energy storage system prototypes in relevant or operational environments. There will be 3 key technology categories across both streams: Power-to-X, Thermal, Electric.
The deadline to express interest in Stream 1 or Stream 2 is 12/04/21.
All demonstrations would be expected to demonstrate flexibility services to and from the grid. Solutions with UK commercial deployments would be out of scope (e.g. lithium ion, pumped hydro, water tanks).
The competition could encompass energy storage technologies that:
- could be deployed at large scale,
- could provide competitive flexibility services and system benefits for the electricity system
- provide longer-duration storage capability (over 4 hours, longer durations scoring higher)
