Invinity has confirmed that nine developers have selected the flagship ENDURIUM flow battery for project bids in the UK’s long duration energy storage Cap and Floor support programme. While not all project details have been made public, early information suggests that three of the nine developers represent c.13.4GWh of capacity. We think the full nine could easily take capacity over 20GWh. Of course, not all project bids will be successful, but we think the quantum here bodes well for Invinity and provides strong support for our mid-term forecasts.
