Are flow batteries the future of home energy storage? Q&A with Redflow’s Simon Hackett

RedFlow’s ZCell is one of the most is one of the most in-demand battery storage products on the Australian market; it also stands out for being one of the only ‘flow batteries‘ currently available. Solar Choice had the opportunity to catch up with RedFlow CEO Simon Hackett about the role of flow batteries (and the ZCell) in Australia’s energy transformation, in the process discussing how the ZCell compares to the vast array of lithium-based batteries sweeping the market. Our conversation is included below. Continue reading “Are flow batteries the future of home energy storage? Q&A with Redflow’s Simon Hackett”

Tesla Powerwall demand jumps 30 times after blackouts

by Financial Review, Simon Evans
Demand for Tesla’s Powerwall home storage batteries has jumped more than 30 times at some large installers after power blackouts in two states.

Installers say “blackout proofing” has become a new buzzword among householders.

The surge in inquiries about home storage battery systems has been almost overwhelming as it adds a new level of demand from customers previously focused on environmental considerations and reducing power bills from weaning themselves off the traditional electricity grid.

Natural Solar managing director Chris Williams, who runs a national firm with its headquarters in Sydney, said the biggest jump had been in South Australia and Victoria, but demand had spiked across the country after the blackouts put the future of electricity grids and renewable energy sharply into the national spotlight.

Redflow says first ZCell batteries to be installed in homes in October

By reneweconomy.com.au

Australian battery technology developer Redflow says the first of its ZCell residential battery storage systems are due to be delivered to customers next month after the first shipment of batteries arrived in Australia on Sunday.


The Brisbane-based company has experienced a series of delays, including an unedited departure delays at the port of Los Angeles, but deliveries will commence in October after the batteries are installed into the Australian-made enclosures.

Redflow says it will announce names and details of the first group of Australian companies with approval to install ZCell energy systems on the ZCell.com website this week. These companies will be able to provide ZCell proposals for retail customers and install ZCell-based energy systems around Australia.

Redflow Ltd to begin installation of advanced energy storage system

By proactiveinvestors.com.au

Redflow Ltd (ASX:RFX) is on track to begin installation of its ZCell energy system, after the first shipment of ZBM2 batteries arrived in Australia yesterday.

ZCell is an energy storage system built by Redflow using ZBM2, the world’s smallest production zinc-bromide hybrid flow battery.

The ZCell system can deliver 10 kilowatt hours of stored energy each day, harvesting energy from solar panels or lower-cost off-peak power.

Installing ZCell with a suitable inverter as part of an energy management system can lower power costs and provide resilience during grid power cuts.

Redflow expect ZCell installations for Australian customers to commence from early October, following customs clearance, inspection and installation of batteries into ZCell enclosures.

What is battery ‘end of life’?


‘End of life’ is one of the key specifications that you should keep in mind as you compare battery storage options for your home. How is battery end of life defined, and why is it so important?

Defining battery end of life

If you have a battery storage system installed on your home, its lifespan can be explained in three different ways. It’s very important for you as a consumer to understand these terms in order to meaningfully compare products – preferably across all three metrics.

  • Cycle life – The number of times the battery can be fully charged and discharged (one cycle).
  • Warrantied life – Usually described in years (e.g. 10 year life under warranty). You may also see ‘expected operational life’ pop up from time to time – this will usually be a few years longer than the warrantied lifespan, but it’s best to think of this as a bonus, as this extra term of operation is not covered under warranty.
  • Total energy throughput – The total amount of energy you can expect to ‘pass through’ the battery during its life (e.g. 30 megawatt-hours).

RedFlow’s ZCell: An Aussie-designed flow battery for homes

RedFlow’s ZCell is currently one of the most talked-about battery storage products on the Australian market. Slated to be available in Australia in the very near future, the battery has significant advantages over most of the other products on the market – and it sure to appeal to the tech-happy ‘early adopter’ market despite its price point (which – though high – is in the ballpark of its competitors). As time goes on and prices come down, the ZCell’s appeal is almost certain to spread to a mass market thanks to its unique warranty structure and resistance to operational wear-and-tear.

Redflow in tie-up with Redback Technologies to smarten up battery offering – The Australian Financial Review

Technologies in an alliance it expects to smooth the path to market for its ZCell home battery and help overcome the greater popular recognition for rival lithium-ion batteries such as Tesla’s Powerwall.

The tie-up, to be announced on Tuesday, comes after months of testing the Redflow battery, which uses zinc bromide “flow” technology – much less well known than the lithium-ion technology – alongside Redback’s solar hybrid inverter.

It confirms that Redflow’s 10 kilowatt-hour ZCell battery is compatible with the Redback inverter, as well as with the product from Netherlands-based Victron Energy, which it is already working with.

“Our aim is to make sure our battery is highly compatible with industry in general,” Redflow chairman and technology entrepreneur SImon Hackett said in advance of the announcement.

Redflow top 20 energy storage disruptors – PV Tech

The term disruptor is thrown around a lot these days in a world rapidly facing digitisation and the fight to stay relevant is becoming ever more competitive in energy storage. While technological breakthroughs are always exciting, to paraphrase an old saying, there’s a lot that can go wrong between filling a cup with liquid and putting it to your lips. In the race to commercialise technologies and business models for a mass market still in its infancy, the real disruptors in energy storage aren’t just in the lab, they are making a real difference in houses, commercial buildings and on and off the grid.
