Zinc bromide battery startup Gelion has started up manufacturing operations in Australia which lean on existing production techniques for lead-acid batteries.

Eos Energy Enterprises has said that equipment and machinery will begin arriving next month as the zinc-based battery storage company expands its manufacturing facility near Pittsburgh.

It’s been predicted for some time that the redox flow energy storage space will, after some turmoil and rapid consolidation, find success in providing energy storage at durations of more than four hours. This past couple of weeks have been a tale of both turmoil and success.

Over the past couple of weeks, various flow battery makers have touted new sales and supply chain agreements as the fledgling sector fights for a share of the stationary energy storage market.

Primus Power, a flow battery maker which claims its systems can cost less than half the price of lithium-ion energy storage over its lifetime, is establishing manufacturing lines in China.
