Simon Hackett with the redesigned Redflow LSB

Redflow simplifies Large Scale Battery design

Redflow Limited (ASX:RFX) has simplified using its batteries in large energy storage systems by integrating plug-and-play technology into its LSB (Large Scale Battery) reference platform.

Implemented in an LSB installed at Simon Hackett’s Base64 property in Adelaide, the new design incorporates six 12-kilowatt (kW) Victron Quattro 48/15000 battery inverter/chargers with 45 Redflow ZBM2 batteries. By implementing this improved design, the Base64 LSB will deliver an energy storage capacity of 450 kilowatt-hours (kWh).

The LSB Reference Platform is a container-sized deployment of Redflow batteries, which can operate as a single ‘virtual” battery to assist Redflow system integrators with designing and deploying larger energy storage systems. Base64 installed its original LSB in 2016, running it for about a year before undertaking the redesign process in conjunction with Redflow.

Redflow’s first Thai battery stacks arrive in Brisbane

Redflow Limited (ASX: RFX) has today received in Australia the first battery electrode stacks made by its new Thailand facility.

The battery stack (pictured below) is the critical part of the Redflow ZBM2 zinc-bromine flow battery, containing electrodes that charge the battery by “plating” zinc on a membrane and then discharge it by reversing that process, which can sustain 10 kilowatt-hours of energy storage capacity for the battery’s operating life.

At Redflow’s Brisbane headquarters, the Thai-made battery stacks will be installed on ZBM2 battery tank sets (without stacks) which were manufactured last year at the former factory in North America.

Redflow Chairman Brett Johnson said these complete batteries would be tested and then supplied to customers to meet existing orders. “As we manufacture stacks for these approximately 200 tank sets, we will progressively validate high-quality components and sub-assemblies at our factory,” he said.

Mossel Bay goes carbon neutral with Redflow

Mossel Bay Municipality in the Southern Cape province of South Africa has eliminated the carbon footprint of its Technical Services Department buildings by deploying ZBM2 batteries from Redflow.

Installed in late 2016, the four 10 kilowatt-hour (kWh) zinc-bromine flow batteries have enabled the ageing offices to become net exporters of electricity to the power grid through the intelligent storage of energy harvested from 114 rooftop photovoltaic solar panels.

Redflow produces first battery stacks in Thailand

Australian battery company Redflow Limited has achieved a second manufacturing milestone by successfully producing the first battery electrode stacks from its new factory in Thailand.

The battery stack is a critical part of the Redflow ZBM2 zinc-bromine flow battery, containing electrodes that charge and discharge the battery by “plating” and “deplating” zinc on a membrane – a process that can sustain 10 kilowatt-hours of energy storage capacity throughout the battery’s operating life. Redflow produced its first battery components from the factory last month.

ASX-listed Redflow (ASX: RFX) reports that the factory has set up and qualified its battery stack machines and processes, optimising them for Thai environmental conditions.

Redflow Limited Managing Director and CEO Richard Aird said assembly of the battery stacks in Thailand had gone according to plan. “The manufacturing team is very happy with the consistent quality and acceptable yield metrics of the stack line,” he said.

Redflow makes first battery components in Thailand

Redflow Limited has successfully started manufacturing core components for its zinc-bromine flow batteries at its new production facility in Thailand.

During the past week, Redflow began producing electrode inserts made of HDPE (High-Density Polyethylene) plastic on the production line at the factory in the Hemaraj industrial estate, south-east of Bangkok. The electrode inserts – produced from custom-made highly conductive plastic – use a bipolar design to enable a zinc-plating reaction on one side and a bromine reaction on the other.

Redflow CEO Richard Aird said production of the first components was going according to plan, as outlined last month at the company’s Annual General Meeting in Brisbane. “We remain on track to produce full battery stacks from our Thai factory next month,” he said.

Redflow aims for 250 batteries/month from Thailand

Australian battery company Redflow Limited aims to produce as many as 3000 batteries a year from its new Thai factory, which it is currently fitting out, reports Redflow Chairman Brett Johnson.

In a letter to shareholders, Mr Johnson said that once the Thai facility was fully operational, it would have the capacity to manufacture as many as 250 batteries a month. “I am confident that once our new factory is producing quality batteries, Redflow will be able to demonstrate that it has a unique and viable product with real benefits for many energy storage applications,” he said.

Queensland home sets Redflow residential record

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.  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. Continue reading “Queensland home sets Redflow residential record”
