News in brief from the week in energy storage around the world.

Australian battery company Redflow Limited has repeated its largest-ever sale of its ZBM2 zinc-bromine flow batteries after receiving an international order worth about US$600,000.

An energy storage market and tech analyst has told Energy-Storage.News a decision by flow battery maker Redflow to shift focus away from the residential market signals that it is “highly unlikely” the technology can compete with lithium-ion in that space.

Australia-based flow battery provider Redflow has paused deliveries of new batteries after a number of unexpected product mode failures during remote monitoring at customer sites, according to a filing on the Australian Stock Exchange.

Chinese energy storage company TrinaBEST launched its residential storage product for the Australian market at last week’s All Energy show, while the USA’s Enphase and Australian flow battery maker Redflow were among the other exhibitors showcasing residential products.

Australia-based flow battery provider Redflow has halved the price of its zinc-bromide battery (ZBM) to the point where the cost of energy produced from its battery drops below the price of energy from the grid.
