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.

A Queensland family has chosen ZCell batteries to guarantee that their new home has electricity without any power bills in the largest Australian residential energy storage system to date for Redflow Limited.

The Bates family’s six-battery, 60 kilowatt-hour (kWh) system ensures complete off-grid operation for their recently built home on a cattle and grain property, about 2.7 kilometres from mains power.

When Scott and Breeann Bates built their new house near Wallumbilla, they chose a ZCell-based energy storage system to give them uninterrupted power, grid-independence and no power bills rather than pay many thousands of dollars per kilometre to connect mains power to the house.

ZCell batteries are produced by Redflow Limited, the ASX-listed company that has developed the world’s smallest zinc-bromine flow battery. The system was installed by Off-Grid Energy Australia.

Breeann Bates said the ZCell-based system was living up to their expectations. “We are really impressed with it,” she said. “Scott wanted to be able to do everything on batteries that we could do on mains power and not compromise our way of living. It’s cold in the morning, so we’re running the heaters to keep our three kids warm, and we keep them on until the day warms up.

Australian battery company Redflow Limited has started installing battery production equipment at its new factory in Thailand, putting it on track to commence initial operation by the end of this year.

Through its Thai subsidiary, Redflow has signed a three-year lease on the 1500-square-metre building at the Hemaraj Chonburi Industrial Estate, part of the IEAT free trade zone, 110km southeast of Bangkok and 25km from the Laem Chabang deep sea container port.

Redflow CEO Richard Aird recently visited Thailand to finalise the lease agreement with David Nadone, Chief Executive Officer and President of Hemaraj Land and Development Public Co Ltd, a subsidiary of WHA Corporation.

Two ZCell zinc-bromine flow batteries installed at Adrian Shand's Glenlyon cottageVictorian sound engineer Adrian Shand is using renewable energy to power his rural stone cottage after installing two ZCell batteries from Australian company Redflow Limited.

Adrian and his partner, who live at Glenlyon in central Victoria, have used their ZCell batteries to maintain a “city lifestyle” in the country, without having to “calorie count” their daily energy use.

The self-declared “tree changer” couple, who own energy efficient appliances and insulated the cottage's roof, have plenty of solar-generated energy to power their home, including multiple computers and professional musical amplifiers that Adrian requires for his sound engineering work.

Although the cottage had existing photovoltaic solar panels and a lead-acid battery when they moved in, Adrian and his partner decided to upgrade both the solar panels and the battery to make the property truly grid-independent without heavy use of a diesel backup generator. Redflow’s 10 kilowatt-hour (kWh) zinc-bromine flow batteries, which the solar panels can fully charge in just four hours on a sunny day, deliver clean power that does not interfere with Adrian’s elaborate musical equipment.

Adrian said the energy storage system had cost $56,000 – about one quarter of the $200,000 cost of connecting mains power to the property. “It means we never receive another power bill,” he said.
