Overview

Australian Vanadium Limited and Sumitomo Electric Industries are positioning a joint bid into Western Australia’s 500MWh flow battery procurement, framing the project as a long-duration vanadium flow battery build (10-hour discharge) with a reported completion target of 2029. The story is being amplified via trade coverage and community sharing, but remains centered on the same partnership-and-bid announcement.
