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.


Simon Hackett with his Tesla Model S in front of the Redflow LSBTechnology entrepreneur Simon Hackett has installed a Redflow LSB energy storage system at his Adelaide office, Base64, guaranteeing at least four days of continuous energy supply.

Base64’s LSB (Large Scale Battery) contains 60 ZBM flow batteries in a 20ft shipping container form-factor, which can deliver 660 kilowatt hours (kWh) of energy in a full discharge cycle. The LSB can be charged from solar and store more than four days of the typical energy requirements of the 2777-square-metre Kent Town property - a multi-tenanted facility routinely occupied by more than 50 people - significantly reducing Base64’s need for grid energy and associated carbon emissions.

Mr. Hackett, who is Executive Chairman of Redflow Limited (ASX:RFX), said the LSB would store energy harvested from Base64’s existing array of 80 PV solar panels. “It will provide us with an enormous degree of energy independence,” he said.

ZCell can store 10 kilowatt hours (kWh) of energy, allowing people to ‘timeshift’ solar power from day to night, store off-peak power for peak demand periods and support off-grid systems.

Australian residential installations are scheduled to start mid year, kicked off by an introductory rebate offer for eligible Redflow shareholders. Full details of ZCell and the opportunity to reserve a ZCell battery are available at International availability will be announced in coming months.

Redflow Executive Chairman Simon Hackett said ZCell was a breakthrough system. “ZCell breaks many of the rules that apply to legacy batteries, making it ideal for the home market,” he said.

Redflow non-executive director Patrick TapperAustralian battery manufacturer Redflow Ltd has appointed experienced technology industry executive Patrick Tapper to its board of directors, just one week before its residential battery launch.

With more than 25 years experience in the telecommunications, technology, media, and entertainment industries, Mr. Tapper will hold a non-executive role as ASX-listed Redflow (ASX: RFX) starts its next phase of growth.

Mr. Tapper, a Fellow of the Australian Institute of Company Directors, already holds non-executive director roles with Silver Chef Ltd (ASX: SIV), Acurus Pty Ltd, and SYC Ltd. He previously worked with Redflow Executive Chairman Simon Hackett from 1998 to 2013 at Internode, where he was CEO and Executive Director.
