UK government awards funding to longer-duration energy storage tech projects – EQ Mag Pro
The first awards of funding designed to “turbocharge” UK projects developing long-duration energy storage technologies have been made by the country’s government, with £6.7 million (US$9.11 million) pledged.
The total £68 million competitive funding opportunity was launched by the Department for Business, Energy and Industrial Strategy (BEIS) in June 2021 through the national Net Zero Innovation Portfolio (NZIP).
Announced this morning — as BEIS innovation programme manager Georgina Morris prepares to join speakers at the Energy Storage Summit 2022 in London today and tomorrow, hosted by our publisher, Solar Media — a total of 24 projects have now received funding through the Longer Duration Energy Storage Demonstration Programme.
The awards are split into two streams: Stream 1 is for demonstration projects of technologies considered close to commercialisation and aiming to accelerate that process so that they can be deployed on the UK energy system. Stream 2 seeks to accelerate the commercialisation of innovative projects through building “first-of-a-kind” prototypes of full systems.
The five awarded Stream 1 projects are a membrane free green hydrogen electrolyser, gravity-based energy storage, vanadium redox flow battery (VRFB), advanced compressed air energy storage (A-CAES) and a bundled solution of pressurised seawater and compressed air.
Thermal storage technologies were eligible, but none have received funding.
Stream 1 projects will receive funding ranging from £471,760 to £1 million per project.
There are however six thermal energy storage technologies among the 19 Stream 2 awardees. Stream 2 winners must deliver feasibility study reports for their proposed technologies and contribute to knowledge sharing and “sector capacity-building,” BEIS said.
Stream 2 funding ranging from £79,560 to £150,000 went to the six thermal storage projects, four power-to-x category projects and nine electrical energy storage projects.

After launching the competition last year, BEIS opened up a three-month Call for Evidence on long-duration energy storage in July, assessing how best to enable long-duration technologies at scale.
A recent report from energy industry consultancy Aurora Energy Research found that up to 24GW of energy storage with a duration of four hours or greater could be needed to enable a net zero energy system in the UK by 2035.
This would enable the integration of variable renewable energy generation and also lower household energy bills by £1.13 billion a year in 2035. It could also reduce the country’s reliance on gas by 50TWh each year and lead to a 10MtCO2 reduction in emissions.
Aurora said however that high upfront costs, long lead times as well as a lack of revenue certainty and market signals are resulting in long-duration energy storage being underinvested into. Policy support and market reforms were recommended in the group’s report.
Another report by KPMG published a few weeks ago said that a cap and floor mechanism would be the best way to reduce investor risk while encouraging operators of long-duration facilities to respond to electricity system requirements.
In the US, the Department of Energy is hosting the Energy Storage Grand Challenge, a policy-driven effort to reduce costs and accelerate the adoption of energy storage, including a similar competitive funding opportunity for long-duration technologies and projects. Its aims include reducing the cost of long-duration energy storage 90% by 2030.
Meanwhile a cluster of European trade associations made a recent plea for the European Union (EU) to take a similarly proactive stance to support long-duration energy storage, particularly in the European Green Deal package.
