ESS is now building an iron flow battery gigafactory at Maryborough

Construction has begun of a factory for long-duration flow batteries using iron and saltwater electrolyte in Queensland, Australia.
The ceremonial first turning of sod on the site was announced yesterday by the Queensland state government and by the company behind the A$70 million (US$47.67 million) project, Energy Storage Industries Asia-Pacific (ESIAP).
Located in the Queensland city of Maryborough, the facility’s construction was welcomed by dignitaries in attendance, including Queensland Deputy Premier and State Development minister, Steven Miles, who is also a local parliamentary representative for the city.
“In the near future, power generated from a nearby wind or solar farm will be stored in iron flow batteries and help power Queensland,” Miles said.
“This manufacturing facility shows industry has confidence to invest in Queensland.”
The state government recently committed A$15 million to support the scale up of the National Battery Testing Centre in Brisbane, Queensland’s capital city, and is preparing to launch a Queensland Battery Strategy later this year.
The iron electrolyte flow battery is IP held by US manufacturer ESS Inc. Unlike vanadium redox flow batteries for which many patents expired several years ago, Oregon-headquartered ESS Inc remains the only company able to manufacture and license the technology.
