“Game-Changing” Long-Duration Energy Storage Projects To Store Power In Hydrogen, Compressed Air And Next-Gen Batteries Win UK Government Backing

The title of this post, is the same as that of this press release from EDF.

These are the first two paragraphs.

EDF UK has received £2 million in funding from the Department for Business, Energy & Industrial Strategy (BEIS) to support four innovative methods of storing energy for longer periods of time.

The four longer-duration energy storage demonstration projects will help to achieve the UK’s plan for net zero by balancing the intermittency of renewable energy, creating more options for sustainable, low-cost energy storage in the UK.

These are the projects.

Tech Transfer And Modification Of Metal Hydride Storage Used In Fusion Sector For Hydrogen (Protium) Storage

The project is described like this in the press release.

The first project will store electricity as hydrogen in a chemical form using depleted uranium hydride (UH3). The project will utilise Urenco’s depleted uranium liability – a waste product from fuel production and reprocessed spent MOX fuel – to safely store hydrogen as UH3, which has approximately twice the volumetric energy density as liquid H2. The project will see EDF R&D lead a consortium combining expertise in engineering and materials from University of Bristol, operating metal hydride storage at UKAEA and handling depleted uranium from Urenco.

Sounds like a good project. Especially, as it finds a use for Urenco‘s depleted uranium.

Pivot Power

Pivot Power, part of EDF Renewables, will work on two projects.

  • Delivering Power On Demand From Solar PV Using 40MWh Vanadium Flow Battery Storage System
  • Accelerate Commercialisation Of Zinc-Based Battery Storage

The first project was described in Longer Duration Energy Storage Demonstration Programme, Stream 1 Phase 1: Details Of Successful Projects.

This is what EDF says about the two projects which are linked.

Pivot Power, part of EDF Renewables, will support the delivery of two demonstration projects. The first project, delivered in partnership with Invinity Energy Systems plc (AIM:IES), will establish the feasibility of developing one of the UK’s largest storage-enabled solar power resources. If selected, Phase Two of this project, which includes a utility-scale 10 MW / 40 MWh Invinity Vanadium Flow Battery, would receive funding under the programme.

Pivot Power will also work alongside e-Zinc, with support from Frontier Economics, to ‘metalize energy’, deploying breakthrough technology that stores energy in zinc, an inexpensive and widely available metal that has a high energy density.

I’m a believer in storing energy in zinc, until it is proven, it’s not a good method.

The final project was also described in Longer Duration Energy Storage Demonstration Programme, Stream 1 Phase 1: Details Of Successful Projects.

The EDF press release adds this.

The final project will explore how electricity, converted into compressed air, can be stored in EDF’s existing gas storage facilities, where EDF Thermal Generation and R&D will partner with io consulting and Hydrostor.

I have a good feeling about this project.
