Recommendation 51
51
Accepted
Paragraph: 174
Actively support renewable energy generation paired with sufficient storage for UK energy self-reliance
Recommendation
Renewable energy generation paired with sufficient energy storage will allow the UK to become more self-reliant, secure national energy supplies and provide a buffer against energy price hikes. This is a future that the UK should embrace, and that the Government must support actively.
Government Response Summary
The government agrees on the importance of long-duration energy storage, has decided to introduce a cap and floor scheme for LDES with a first application round expected in 2025, and is committed to designing a new business model for hydrogen storage by 2025.

HM Government

Government agrees with the importance of long-duration energy storage as a key enabler to a secure, cost-effective and low carbon energy system. Long duration energy storage, for example electricity or hydrogen storage, can help to decarbonise the system by storing excess renewable generation over longer periods of time. This will allow us to replace fossil-fuelled generation with renewable power without losing flexibility from the grid. Long duration electricity storage (LDES) will save consumers money, as it minimises the amount of additional generation and network capacity needed. System modelling estimates savings for the energy system, and ultimately the energy consumer, of £24 billion by 2050 in one scenario1. On 10 October 2024 the Government published its decision to introduce a cap and floor scheme for LDES, with Ofgem as regulator and delivery body. Future procurement ambitions for this scheme will be provided ahead of the first application round, which is expected in 2025. NESO’s Clean Power 2030 analysis contains scenarios for future storage deployment (both LDES and batteries). We will continue to work with NESO to develop projections of future system need, e.g. in preparation for next steps on delivery of the LDES cap and floor scheme. Low-carbon hydrogen can also act as a flexible generating technology and provide long duration energy storage, making use of curtailed electricity. We are committed to designing, by 2025, a new business model for hydrogen storage infrastructure and how best to enable private sector investment and remove market barriers. The Energy Act 2023 provides the legislative framework that will underpin the delivery of the hydrogen transport and storage business models.
