Funding opportunity: Develop and integrate energy storage technologies at grid scale

Apply to do fundamental research into developing and integrating technologies to enable energy storage at grid level.

You must be based at a UK research organisation eligible for EPSRC funding.

Your project must be at least 50% within the remit of EPSRC.

The full economic cost of your project can be up to £1.5 million. EPSRC will fund 80% of the full economic cost.

We are interested in the following areas:

  • mechanical storage systems
  • compressed-air energy storage
  • storage of heat, hydrogen or natural gas
  • heat pumps or pumped heat electrical storage.

This is not an exhaustive list and we welcome proposals in alternative and novel areas.

  • hold fellowships under other schemes (please contact EPSRC to check eligibility, which is considered on a case-by-case basis).

Holders of postdoctoral level fellowships are not eligible to apply for an EPSRC grant.

If you are currently restricted under the repeatedly unsuccessful applicants policy, you may submit unlimited outlines but you will only be able to submit one full proposal (as principal investigator or co-investigator) during the 12-month restricted period.

Submissions to this opportunity will count towards the EPSRC repeatedly unsuccessful applicants policy.

What we're looking for


This is an opportunity for funding proposals in fundamental research which applies to energy storage at grid scale. This can be development of new storage technologies or integration of technologies to grid scale.

Both short-term balancing technologies and long-term inter-seasonal technologies are of interest.

For more information on the background scope of this funding opportunity, please see the grid scale energy storage workshop report (PDF, 196KB).

While we understand research in this area can be interdisciplinary, the project must be in the remit of EPSRC with at least 50% of the proposed work falling within the energy theme at EPSRC.

The following are of interest. Please note this list is not exhaustive and alternative or novel areas are welcome:

  • mechanical storage systems
  • compressed-air energy storage
  • storage of heat, hydrogen or natural gas
  • heat pumps or pumped heat electrical storage.

We do not require specific industrial collaboration to be included in the application. However, support from project partners is welcome and letters of support can be attached to the full proposal submission, if appropriate.

Out of scope

Proposals that do not fall within EPSRC remit or are not sufficiently focused on the development or integration of grid scale energy storage will be rejected.

Due to other opportunities that are available in these spaces, we will not fund projects that could be described as:

  • battery technologies
  • formation of chemical storage vectors (such as hydrogen).

Funding available

We plan to award approximately 8 to 10 proposals from this opportunity. Projects will be for 24 months in duration and valued between £500,000 and £1.5 million for fundamental research in this area.

Equipment over £10,000 in value (including VAT) is not available. Smaller items of equipment (individually under £10,000) should be under the ‘directly incurred – other costs’ heading.

Find more information on equipment funding.

How we will assess your application

Assessment process

Stage one: intent to submit

In order to submit a full proposal to this opportunity, an intent to submit must be completed.

This stage is not assessed. The remit of the proposed work will be determined at the full proposal stage.

For this stage, we will use the information to plan peer review of the full proposals and understand demand. The questions involved in this survey relate to the involved:

  • investigators
  • costs
  • partners involved
  • objectives for the research.

In the event of this funding opportunity being substantially oversubscribed as to be unmanageable, EPSRC reserves the right to modify the full proposal assessment process.

Stage two: full proposal

Full proposals will undergo postal peer review by community members with appropriate expertise.

There will then be the opportunity for applicants to reply to comments made. The reviews, and response from applicants will then be assessed at a panel of generalists and prioritised for funding, which will inform funding decisions.

Additional info


The UK has committed to reaching net zero by 2050. The future energy system will have an increasing reliance on renewables, which can lead to seasonal disparities due to the intermittent nature of energy supply.

The intermittence experienced across the grid will need to be resolved. This necessitates alternative energy storage technologies or increases to the storage capacity of current storage technologies.

A key factor in reaching decarbonisation goals will be more cost effective, efficient energy storage technologies.

Along with scale-up of existing energy storage and development of new energy storage technologies is the need to integrate these with existing and future infrastructure.

This opportunity aims to fund several fundamental research proposals in the area of grid-scale energy storage. This can be the development of new storage technologies or integration of technologies to grid scale.

This funding opportunity has been developed due to advice gained from the community, in terms of the UKRI Energy Programme Scientific Advisory Committee as well as a workshop held earlier this year.

The report from the workshop contains more detailed information on the type of intervention needed in this area.

Responsible innovation

EPSRC is fully committed to develop and promote responsible innovation. Research has the ability to not only produce understanding, knowledge and value, but also unintended:

  • consequences
  • questions
  • ethical dilemmas
  • social transformations.

We recognise that we have a duty of care to promote approaches to responsible innovation that will initiate ongoing reflection about the potential ethical and societal implications of the research that we sponsor and to encourage our research community to do likewise.

Therefore applicants are expected to work within EPSRC framework for responsible innovation.

Applicants planning to include international collaborators in their proposal should get more information and advice on trusted research from the Centre for the Protection of National Infrastructure. This is so they can get the most out of international collaboration whilst protecting intellectual property, sensitive research and personal information.
