Queensland-based stream battery firm, Redflow, has commissioned a 30 kWh zinc-bromine stream battery for Brisbane Metropolis Council.
From pv journal Australia
Brisbane Metropolis Council has chosen to put in a Redflow battery to enhance vitality effectivity at its Willawong Animal Rehoming Heart in south Brisbane.
The 30 kWh zinc-bromine stream battery undertaking is deployed with Redflow’s new integration associate, Shiny Spark Group, and consists of two Deye hybrid inverters to permit the photo voltaic system to be expanded sooner or later.
The Willawong Animal Rehoming Heart website is the primary in Brisbane Metropolis Council’s wider plan to enhance the resilience of presidency websites throughout town, referred to as the ‘Higher Brisbane Proposals’ initiative. The Redflow battery system is funded by way of this system.
The Willawong Animal Rehoming Heart was chosen for the preliminary website as a consequence of ongoing points with grid outages, which affected the storage of vaccines and medicines.
Battery stream overview
Circulate batteries are a distinct animal from mainstream lithium-ion batteries, the area of giants like Tesla. Lithium-ion batteries are solid-state batteries that retailer vitality in steel. Circulate batteries, alternatively, retailer vitality in liquid electrolytes. They’re normally designed with two tanks, one containing a positively charged anode and the opposite containing a negatively charged cathode, separated by a membrane.
The usage of liquids permits stream batteries to provide electrical currents with out degradation, giving the batteries an extended cycle life and permitting them to carry a cost for longer durations of time. in comparison with lithium-ion batteries. Circulate batteries will also be totally discharged with out harm, and are simply scalable – they are often stacked on prime of one another to extend capability.
Circulate batteries additionally lend themselves to recycling, which is a facet Redflow CEO and Managing Director Tim Harris thought shall be significantly related for Redflow’s general providing – particularly provided that solely 2% of Australia’s lithium-ion battery waste is presently recycled.
The stream of batteries pitfall? Dimension. Fluid tanks, by nature, can solely be very small. That is a part of the rationale lithium-ion batteries are so quick out of the gate – we’d like small, highly effective batteries that last more than our fundamental home equipment. Though much less appropriate for bigger purposes, lithium-ion batteries profit significantly from their ubiquity and visibility, having been used for many years in our telephones, laptop computer chargers and now in our EVs .

After years of predictions across the daybreak of the battery age, it seems that the decades-old know-how is lastly capturing a few of the storage market. Final yr, Redflow grew to US market and combines its methods with a variety of inverters.
There are a variety of run battery corporations and tasks within the pipeline in Australia, together with Vitality Storage Industries’ manufacturing manufacturing unit in Maryborough, Queensland, the place it would assemble iron-flow batteries from its “deep tech associate” ESS Inc. Sydney startup Gelionand VSUN Vitalitya subsidiary of Perth-based mining firm Australian Vanadium Restricted (AVL), additionally intends to broaden the manufacturing and deployment of stream batteries in Australia.
