Updated 12 April 2023

Stream 1 aims to accelerate commercialisation of innovative longer duration energy storage projects through to actual demonstrations. During Phase 2, the project will be expected to build and commission its proposed technology.

The following project has received funding for Stream 1, Phase 2.

Electrical energy storage

Project Name: Vanadium Flow Battery Longer Duration Energy Asset Demonstrator (VFB LEAD)

Led by: Invinity Energy Systems
Project Location: United Kingdom

Invinity Energy Systems has been awarded £11 million for the VFB LEAD project to build a 30 MWh Vanadium Flow Battery (VFB) that will be deployed at a key node on the National Grid. The 7 MW VFB will perform a broad range of grid balancing services, providing vital flexibility to the electricity network and supporting the further buildout of renewables. Invinity’s VFB will be the largest battery ever manufactured in the UK and one of the largest of its kind anywhere in the world. Additionally, being capable of over 4 hours rated charge/discharge duration, VFB LEAD will be the longest duration battery to be connected to the UK grid to date.

Invinity will manufacture the VFB at the Company’s factory in West Lothian, Scotland. The £11 million of matched funding for the VFB LEAD project has been awarded through the LODES Stream 1 competition and the project is expected to go live in early 2025.
