Black Wattle 2 WBlack wattle (Acacia auriculiformis) - ‘soap’ plants that have been long-used by Bininj

A few months ago, a message appeared on Facebook.  Posted by a family member living in Arnhem Land it told of the electrocution of a child.  The women present did not administer CPR or call for medical assistance.  Rather, they prayed over him.  

When the coronavirus pandemic threatened there was another message from the same person, but the tone was more anxious this time.  It consisted of a photograph of a woman praying and below the message in large letters that God and prayer would protect people from the coronavirus.  As before several other women supported her post and they all sounded scared. 

The juxtaposition of these two messages led me to fear that if COVID-19 did make it to Aboriginal settlements, prayer would be the first port of call, at least for some.  An infectious diseases specialist friend has described the potential ramifications as ‘horrifying’.

Redflow Managing Director and CEO Tim Harris

Australian energy storage company Redflow Limited (ASX: RFX) has received a subsequent order for its ZBM2 zinc-bromine flow batteries for deployment by New Zealand’s Rural Connectivity Group (RCG).

Redflow, which supplied an initial eight batteries for use by RCG in November 2019, has received a follow on order for an additional 10 batteries for installation at two new off-grid RCG telecommunications transmission towers in the North Island of New Zealand. Local RCG partner Switchboard Services has placed the order and will undertake ZBM2 installation works. This repeat order follows the successful installation and commissioning of Redflow’s ZBM2 batteries at two RCG towers late last year.

Redflow Managing Director and CEO Tim Harris said this order for ZBM2 batteries at further RCG sites demonstrated the benefits that Redflow’s zinc-bromine flow battery technology delivered to telecommunications companies. “These benefits include long-life performance, heat-tolerance and theft-resistance,” he said.

Redflow batteries at Swansea University in Britain
Redflow batteries at Swansea University in Britain

Swansea University, a research-led British university, has purchased Redflow’s unique ZBM2 zinc-bromine flow battery technology as the energy storage backbone for its Active Building demonstrator -– an award-winning classroom that generates, stores and releases solar energy at the point of use.

The microgrid is built around 120 kWh of Redflow batteries and is supplied with building-integrated, thin-film photovoltaic solar panels, as well as a solar wall that supplies the warm air to a heat-pump for space and water heating.  Since being built, the classroom has proven the Active Buildings concept by generating more energy than it has used over an annual cycle, and during high solar summer months, the system will return power to the local electricity grid.

Redflow’s small 10 kWh flow battery units provided the only commercially available flow battery energy storage system that allowed accurate sizing for the 120 kWh system. Additionally, the Redflow battery operates “out of the box” with the Victron inverters and controllers that provide the power conversion for the Swansea University minigrid.

Tom Griffiths, Technology Transfer Fellow (Smart Systems), said Swansea selected the Redflow technology because of its ability to deliver 100% of the rated system energy every day, without degradation in capacity over a long – 10 year – life. “These characteristics were crucial considerations for us, and our application requires battery discharge duration of 4-8 hours depending on the time of year, making Redflow’s flow battery the ideal fit for our requirements in comparison to more conventional lead-acid or lithium alternatives.”

Solar panels at Kalyakool Farm supply 14 kWh of energy for storage by Redflow batteries
Solar panels at Kalyakool Farm supply 14 kWh of energy for storage by Redflow batteries

After losing power as the night horizon glowed orange with bushfires last summer, WA orchardists Jeff and Kerry Murray installed Redflow batteries to take their property off-grid and make it energy-independent year-round.

Power outages have plagued the Murrays’ farm - called Kalyakool, a Noongah word meaning “forever more” – since they bought the 34-hectare property near Gingin, 90km north of Perth, in 1994.

Mr Murray said the threat from the December bushfire was “the last straw”. “Our water comes from two bores, so without power, we can’t get any water,” he said. “The summer fire didn’t get to us, but it impinged on us through the loss of power for a whole day, which was followed by multiple outages as they brought it back on. If fire does reach us, we need energy to run the pumps to defend our property, which is why the bushfire was the last straw for us.”
