news Australian energy storage specialist Redflow is set to show its recently launched ZCell home battery and new custom-designed enclosure at the Australian Energy Storage Conference & Exhibition this week in Sydney.
ZCell is a residential energy storage system that includes a flow battery made from easily recyclable or reusable components.
A flow battery is a rechargeable system powered by two different liquids separated by a membrane across which ion exchange occurs.
Redflow’s system’s 10kWh of stored energy allows people to store daytime solar power and use it at night, or store off-peak power for peak periods.
ZCell offers a number of benefits, such as allowing 100% of energy to be discharged without battery damage, and the ability to be stored indefinitely without requiring maintenance charging.
Its creators also tout the battery’s safety features, including no risk of explosion following mechanical damage, no risk of ‘thermal runaway’ – when increased temperature leads to further increases in temperature, and an electrolyte that is fire retardant.
Further, ZCell can perform well in hot, remote locations without the need for external cooling until an ambient outside temperature of at least 45ºC.
The new outdoor-rated enclosure, measuring around 1 metre long, by 0.5m wide and 1.15m high, has been custom designed to hold Redflow’s 10 kilowatt hour (kWh) ZBM2 flow battery.
Simon Hackett, Executive Chairman at Redflow, who is to speak at an opening session of the Sydney conference, said the ZCell enclosure was designed and is being manufactured in Australia.
“This is the first time we have shown our ZCell enclosure publicly,” Hackett added.
“We’re very pleased with the design, which is both attractive and practical, that allows straightforward outdoor installation, and features a built-in secondary containment system to protect against the unlikely event of an electrolyte fluid leak,” he said.
Redflow expects to receive the first production batch of enclosures for quality assurance testing before the end of June, Hackett explained, with ZCell bundles now likely to be delivered to installers for customer deployment from August.
The firm has already installed demonstration ZCell systems at a number of Australian sites and is now developing documentation and training processes for the accreditation of qualified installation partners.
Redflow said it has received a “strong response” to the ZCell launch from prospective customers and potential installers.
“We are installing selected exemplar systems during June and July, with larger volumes of ZCell batteries scheduled to start arriving from August,” said Hackett.
ZCell’s international availability will be announced in coming months.
The Australian Energy Storage Conference & Exhibition taking place from 1-2 June at the Australian Technology Park in Sydney.
Hackett will participate in the conference’s opening panel discussion – titled “The disruption driving the New Energy Grid” – at 10am today.
