Longer duration energy storage demonstration-stream 1 (pre-commercial demonstrator grants)

Project Size:
Phase 1 £1M, phase 2 £11M


As part of the Government’s 10 Point Plan for a green industrial revolution, BEIS has launched the £68M Longer Duration Energy Storage Demonstration Programme, to support the demonstration of innovative first-of-its-kind technologies which provide UK power grid flexibility. The programme is split into two funding streams, which target technologies at different maturity levels:

Stream 1 Grant Competition: Pre-Commercial Demonstration TRL 6/7

These cover three technology categories (electricity, thermal, power-to-x), and encompass two phases (1. preparatory, 2. build & commission).

Your proposal must:

  • specify a single technology category (electrical storage, thermal storage or power-to-x)
  • outline technical deliverables which explore potential cost reductions, performance improvements, demonstrate capabilities, and de-risk effective non-conventional storage technologies
  • show applicability of the technology to the UK energy system
  • demonstrate the impact funding can have on business growth
  • identify measurable performance indicators and benefits

Projects can be delivered by a single company or a consortium. To lead a project your organisation must:

  • be a business of any size, a research organisation or a RTO, with a base in the UK
  • intend to exploit the results from or in the UK
  • carry out project work in the UK

The minimum technology requirements are:

  • ability to charge using electricity
  • ability to charge for at least 4 hours
  • ability to remain charged for at least 4 hours, without significant self-discharge, before utilising the stored energy
  • must have flexibility to increase electricity demand at times of low demand and high renewable output
  • must be stationary

Stream 1: Grant Competition: Pre-Commercial Demonstration TRL 6/7

This £37.2M grant competition supports capital expenditure for pre-commercial demonstrator proposals.


Phase 1. Mobilisation- put in place technical, legal, financial and commercial measures for Phase 2

  • maximum grant size/project is £1M
  • end by October/November 2022

Phase 2. Demonstration- build and demonstrate technology

  • maximum grant size/project is £11M
  • end by March 2025

Upon Phase 1 completion, project achievements will be considered to determine eligibility for Phase 2 progression. Activity must be experimental development. % funding determined by applicant size.


TRL 6/7. Must not yet be commercially deployed (in UK or elsewhere). Projects will increase TRLs by minimum of 2 levels.
