Invinity to build 20MWh flow battery in UK

Known as the LODES (Longer Duration Energy Storage) Project, the system will be the largest deployed by Invinity to date. It’s expected A solar PV array operated by a third party will be co-located with the energy storage. 

LODES will use Invinity’s VS3 vanadium flow batteries (VFBs) to store solar and grid energy at times of high generation, releasing it back to the grid during peaks in user demand. Though not as energy dense as lithium-ion batteries, VFBs have minimal degradation in performance over time and are better suited to longer term storage as a result. 

The total cost for the battery system – including site acquisition - is expected to be up to £20m. Approximately £7m-£10m will be funded by the Department for Energy Security and Net Zero (DESNZ) through the LODES Demonstration competition. However, Invinity will fully own and operate the asset, something which the company believes will allow it to maximise income through grid balancing and energy trading activities when the project goes live in 2026.
