In this episode, we chat with Graham Arvidson, CEO of Australian Vanadium Limited, on the case for long-duration energy storage and Australia’s opportunity in vanadium flow batteries.

Graham walks us through how flow batteries work, why they’re uniquely suited to long-duration applications, and why their economics flip the equation: every extra hour of duration is just another tank of electrolyte, not another full battery.

He also makes the case for Australia’s supply chain opportunity, given we have the second-largest vanadium resources in the world.
