While lithium-ion continues to dominate big project announcements worldwide, three providers of long-duration non-lithium battery technologies have claimed various milestones in commercialisation.

There exist opportunities for flow batteries to target areas of the market lithium-ion “can’t provide in an economically justifiable way,” the chief commercial officer of Invinity Energy Systems has said.

The proposed merger between flow energy storage companies Avalon Battery and redT continues to progress, with the transaction set to be completed around the end of March 2020.
