Redflow Limited, a publicly-listed Australian company (ASX: RFX), produces small 10kWh zinc-bromine flow batteries that tolerate daily hard work in harsh conditions. Marketed as ZCell and ZBM2, Redflow batteries are designed for high cycle-rate, long time-base stationary energy storage applications in the residential, commercial & industrial and telecommunications sectors, and are scalable from a single battery installation through to grid-scale deployments. Redflow batteries are sold, installed and maintained by an international network of energy system integrators. Redflow’s smart, self-protecting batteries offer unique advantages including secure remote management, 100 per cent daily depth of discharge, tolerance of high ambient temperatures, a simple recycling path, no propensity for thermal runaway and sustained energy delivery throughout their operating life.

As the electricity grid shut down to protect itself during a fierce storm, two Redflow batteries at the Hackett house continued to operate, providing it with electricity, without missing a beat.

At last week’s Redflow AGM, Mr Hackett said the two ZBM2 batteries had worked as intended. “They kept our lights on as the rest of the state was plunged into darkness,” he said.

Redflow is the Australian company that produces the world’s smallest zinc-bromine flow battery, a stationary energy storage technology that competes with lithium-ion batteries. As well as this year’s launch of its ZCell residential battery, Redflow produces ZBM commercial batteries that are used for business, telco and industrial-grade energy storage in Asia, Africa, Europe, Central America and Australia.

In a blog on his website www.simonhackett.com, Mr Hackett said Tesla’s unveiling of its new Powerwall 2 battery with a built-in AC inverter last week took a leaf from the Apple playbook of vertical integration.

Conservation SA CEO Craig WilkinsSA’s peak environmental organisation, Conservation SA, has installed two ZCell batteries to charge an electric car and to provide energy for emergency lighting and data centre backup for its office.

This first installation of ZCell batteries for commercial premises allows Conservation SA to store energy collected from a 13 kilowatt (kW) array of Tindo solar panels on the roof of its building, The Joinery, in central Adelaide. Earlier this week, Redflow announced its first ZCell deployment, a two-ZCell energy storage system installed at Alan Noble’s off-grid property in Willunga.

The Australian-developed ZCell is a unique 10 kWh zinc-bromine flow battery that ‘timeshifts’ solar power from day to night, stores off-peak power for peak demand periods and supports off-grid systems. As well as providing backup power for Conservation SA’s emergency lighting and first floor data centre, the ZCells will charge up the GoGet electric vehicle that is based at the site.
