UK Government Grants £30 Million For Long Duration Energy Storage Projects

The title of this post, is the same as that of this article on Solar Power Portal.

These two paragraphs outline the grants and their recipients.

The UK Department for Energy Security and Net Zero (DESNZ) is providing £30 million in grants for three long-duration energy storage (LDES) projects using novel energy storage technologies.

The three projects awarded funding are from Synchrostor, Invinity Energy Systems and Cheesecake Energy. Synchrostor and Cheesecake Energy are to receive £9.4 million each to fund thermal energy storage systems and Invinity Energy Systems receiving £11 million to develop a vanadium flow battery.

The UK Government seems to give out a lot of these grants for research and development purposes and from feedback I have received from recipients and also by applying my own experience, I am of the opinion, that they are spending tax-payers money more in a wise, rather than a foolish direction.

Cheesecake Energy

I wrote about Cheesecake Energy’s grant in Cheesecake Energy Collects £9.4m Government Funding.

The Government’s press release says this about Cheesecake’s grant.

Cheesecake Energy Ltd, Nottingham, which will receive £9.4 million to test their FlexiTanker technology which stores electricity using a combination of thermal and compressed air energy storage and uses a reversible air compression / expansion train to charge and discharge. They will then install pilot units at 2 sites within a microgrid development in Colchester.

If this project proves successful, it surely is one that can be duplicated in many places.

I have had my eye on Cheesecake Energy for some time and this could be their breakthrough.

Invinity Energy Systems

I first wrote about Invinity Energy Systems in UK’s Pivot Power Sees First Battery On Line By 2021.

The Government’s press release says this about Invinity’s grant.

Invinity Energy (UK) Limited, Scotland, which will receive £11 million to develop and manufacture their 7MW, 30MWh 4-hour Vanadium Flow Battery (VFB), the largest in the UK. Invinity will manufacture the 30 MWh VFB at the Company’s factory in West Lothian, Scotland. The location of the plant will be confirmed in due course.

In this article on, which is entitled Invinity Wins Funds For 30MWh UK Battery, these two paragraphs introduce the project.

Invinity Energy Systems plc has today been awarded £11m in funding by the Department for Energy Security and Net Zero to build what it says is the largest grid-scale battery ever manufactured in the UK.

The £11m in funding will come from the Longer Duration Energy Storage Demonstration (LODES) Competition, with funding matched by Invinity’s, as yet unnamed, project partner.

These are other points from the article.

  • It will be a fast-response 30MWh battery.
  • The battery will be assembled at Bathgate in Scotland.
  • It will operate as a stand-alone energy storage asset.
  • It will be connected to the National Grid.
  • Invinity’s vanadium flow batteries are an alternative to lithium-ion.

The aim is to go live by 2025.

This paragraph indicates the differences between a vanadium flow battery and a traditional lithium ion one.

Invinity said this battery is safer as they cannot catch fire, more durable as they do not degrade with use and are almost completely recyclable at the end of their 25+ year life, reducing environmental impacts and disposal costs for project owners.

I believe that there will come a point, when fully-developed vanadium flow batteries, will become very attractive for financial reasons to the successful energy storage funds like Gresham House and Gore Street.

If the UK government’s funding hastens the day, when energy storage funds feel that these new-fangled vanadium flow batteries are a safe investment, then it is money well spent.

It is not as though the money is going to an early start-up, as this page on the Invinity Energy Systems web site indicates  at least a dozen installations.

This project for an as yet unnamed customer, which has a capacity of 30 MWh, is probably much bigger and the Government help is probably very much welcomed.


SynchroStor was new to me, today.

The Government’s press release says this about SynchroStor’s grant.

Synchrostor, Edinburgh, Scotland, which will receive £9.4 million to build a Pumped Thermal Energy Storage (PTES) grid-connected demonstration plant operating at 1MW, with the ability to charge and discharge for a period of 10 hours, longer than current battery technology.

This page named Technology on their web site, explains their technology, both with words and diagrams.

It is probably the most complex technologies of the three batteries, but I don’t think that will be a problem.


The Government has given grants to three different storage technologies.

If all goes well three good sizable pilot plants will be created and those companies like Centrica, Gore Street, Gresham House, National Grid, Ørsted, SSE and others, will be able to judge, which system is best for their needs.
