What is a vanadium flow battery?

Vanadium flow batteries, like Invinity’s VS3 technology, offer a compelling alternative. These systems provide long-duration storage, have no risk of fire, lower degradation over time, and are better suited to daily heavy cycling without loss of capacity.

Are vanadium flow batteries a viable alternative to lithium-ion batteries?

However, lithium-ion systems face challenges in providing multi-hour to multi-day storage, are prone to thermal runaway risks, and often suffer reduced lifespans under heavy cycling. Vanadium flow batteries, like Invinity’s VS3 technology, offer a compelling alternative.

Are redox flow batteries suitable for grid-scale energy storage?

Redox flow batteries (RFBs) are strong candidates for grid-scale energy storage due to their potential to decouple power and energy capacity. Commercial RFBs (e.g. all—vanadium system) have demonstrated attractive features, such as operation over a large number of cycles.
