Off-grid WA orchard beats bushfire blackouts with 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.”

Redflow receives order for ZBM2 batteries to power rural microgrid in North West Tasmania

Redflow Limited (ASX: RFX) has secured an order to immediately supply 27 of its ZBM2 zinc-bromine flow batteries for a Tasmanian farm owned by Simon Hackett.

Mr Hackett – Redflow’s largest single shareholder – has designed an energy system to deliver energy independence for the 73-hectare property, The Vale (, located in North West Tasmania.

The Vale runs sheep and beef cattle, with ‘The Vale Lamb’ featuring on the menus of multiple hotels along the north-west Tasmanian coast. The farm, which is diversifying into additional forms of agriculture, is also exploring an expansion into eco-tourism operations. The energy harvesting, storage and distribution system at The Vale will use an initial deployment of 27 ZBM2 batteries, storing as much as 270 kilowatt-hours (kWh) of energy, interfaced to a large fault-tolerant cluster of 12 x Victron Quattro 48/15000 inverter/chargers. The system will harvest renewable energy from a 100-kilowatt peak (kWp) ground-mounted array of photovoltaic (PV) solar panels, with scope for future expansion.

Mr Hackett said his goal for the system was to create energy independence for the farm, delivering energy to power both building loads and electric vehicles. “The project, with an overall budget of around $1m, will include the building of a new site-wide microgrid. This will use new underground power interconnects to link seven distinct buildings across the whole property,” he said.

Redflow energy storage in Agriculture

Energy storage has combined with renewable energy generation – primarily solar – in farms across Australia to reduce reliance upon unreliable electricity grids, to reduce diesel consumption and emissions and to reduce costs.

Increasingly Redflow’s zinc-bromine flow batteries are employed in rural applications across Australia with energy storage capacities as large as 600 kilowatt-hours (kWh) to provide primary producers with energy independence.

Redflow is an Australian ASX-listed company that has developed, manufactures and markets an innovative, environmentally sustainable 10 kWh zinc-bromine flow battery. This battery is unique in that it can be fully charged and discharged every day without adversely affecting its energy storage capacity, as occurs with other chemistries. This means Redflow-based energy storage systems do not need to be built oversized to cope with battery degradation. 

The Redflow battery is also well suited to Australian conditions as it can operate at internal temperatures as hot as 50 degrees Celsius (122 F) without the need for active air-conditioning. The Redflow electrolyte is based on bromine, which is used as a fire retardant, so there is no risk of runaway thermal events or uncontained fires, which can occur with other battery chemistries. Redflow also has a positive environmental story as its components can be easily reused or recycled. 

Redflow batteries have a growing market in the Australian agricultural sector, where customers need a reliable, daily supply of stored energy and the lack of degradation to deliver cost-effective energy storage throughout the life of a renewable energy project without the environmental risks of other batteries. Benefits of Redflow zinc-bromine flow batteries include:

  • Flow chemistry is like a reversible electroplating process
  • Unlike conventional batteries, Redflow batteries can repeatedly use 100% of their energy capacity and run flat –  incurring no damage!
  • Excellent tolerance for high ambient temperatures without external cooling
  • World’s most compact flow battery; its modular design enables scalability – 10kWh to MWh!
  • Smart battery including Battery Management System (BMS) with remote monitoring and diagnostics
  • Sustainable: Reusable electrolyte, recyclable HOPE plastic, non-toxic materials, no conflict minerals
  • Built-in battery self-protection features
  • 10 years or 36.5 MWh throughput warranty
  • Not susceptible to thermal runaway or sustaining fire.
