from the 2019 (21 Nov) AGM for Redflex
... as a business we must recognise that whilst the overall market for energy storage has increased significantly and continues to grow, the intensity of competition - particularly from Lithium - has intensified. Bloomberg New Energy Finance notes that the volume weighted price of the average Lithium Ion battery pack fell by 85% from 2010-18.

Like it or not, the reality of our market is now that many areas of the energy storage now use Lithium, and Lithium prices , as their core reference point.

Very true, until the Government has to wear the cost for helping put in the batteries, then they have to wear the fallout from the electorate when the voters have to replace them.
Giving a surfing analogy, everyone is sitting on a board watching the horizon, the rise on the horizon shows, everyone turns their board and gets ready.
Then when it is time to go, some go the older smarter ones say no it just isnt quite right.
At the moment with house batteries the wave is still forming IMO.
That is just my take on it.
With cars lithium wins hands down, with huge bulk storage the same lithium wins hands down, with domestic house use Im not so sure.
The critical factor will be the charge and discharge rate and its suitability for grid intergration.

Flow batteries are perfectly suited to solar storage, the sun shines during the day and the flow battery releases its stored solar during the evening peak, cheap to make and easy to use with many more discharge cycles than lithium, perfect for local distribution.

The market is still very immature, globally smart grids are still to come - we are 20 years into the 3rd industrial revolution, 20 or 30 years to go.

Spot on IMO. Also deeper discharge cycle.
 
Redflow Limited (ASX: RFX) is pleased to announce that it has partnered with Optus to deploy Redflow batteries as part of the Australian Government’s Mobile Network Hardening Program. The Minister for Communications, Urban Infrastructure, Cities and the Arts, the Hon Paul Fletcher, visited Redflow’s Brisbane headquarters to launch the initiative, which is funded in part by the Government’s bushfire relief package.
Minister Fletcher, said: I welcome the fact that Redflow’s innovative Australian technology is being used by Optus in their mobile base station battery upgrades, funded under the Morrison Government’s Strengthening Telecommunications Against Natural Disasters (STAND) program.

Earlier this week, Optus installed its first Redflow battery system under the Government program at a black spot site in Lexton, Victoria. It is planning to deploy Redflow batteries in at least 56 black spot sites as part of the program. Optus has also used Redflow batteries in the environmentally sensitive Daintree Forest in Queensland since 2019.

Another advantage with the flow batteries is they have a low fire risk. I honestly don’t know how lithium batteries can be approved for domestic housing because of the fire risk??‍♂️.

Redflow signs its largest global battery sale to supply energy storage in California
Highlights:
  • Largest single sale and deployment of Redflow batteries globally
  • 2MWh energy storage system comprising 192 Zinc-bromine flow batteries to be provided to Anaergia for Rialto Bioenergy Facility in California
  • More than US$1.2 million (excluding taxes) to be received by Redflow for the system
  • Establishes Redflow’s presence in California, where substantial opportunities exist to offer energy storage solutions to the Californian and US energy market

As part of their largest commercial deal to date, signing a $1.5 million deal to provide 192 zinc bromine flow batteries to California based technology company Anaergia, Redflow will provide the batteries to support two megawatt hours of energy storage at Anaergia's microgrid at its Rialto Bioenergy Facility in San Bernardino County.The microgrid project was partly funded by a grant from the California Energy Commission. It consists of a 2 megawatt biogas-fuelled cogeneration unit and a microgrid control system.

Anaergia chief operating officer Yaniz Scherson said Redflow's batteries suited the Rialto project, which once completed will be North America's largest landfill-diverted waste digester facility. The waste facility will convert about 700 tonnes per day of organic waste and 300 tonnes per day of biosolids from the Los Angeles region into renewable natural gas and Class A fertiliser.
Anaergia selected the Redflow zinc bromine flow batteries because they are uniquely suited to meet the demands of the Rialto site, he said.

The Redflow 10 kilowatt hour batteries will allow the waste facility to store and [then] supply up to 2 megawatt hours of energy daily from 4pm to 9pm, during the peak tariff period. Under the contract, Redflow will receive more than US$1.2 million ($1.5 million) (excluding taxes) for the system.

Redflow managing director Tim Harris said the contract with Anaergia would allow the company to establish a presence in California and the wider US energy market.
It is a bit of a watershed for us and the flow battery. The US market is potentially enormous. ...California is really taking the leadership with renewable energy and the Biden administration has also been a real shot in the arm for the sector. We are very excited about the potential for Redflow in California and the broader US market.

California has committed to decarbonising its electricity grid by 2045, which will require between 45 gigawatts and 55 gigawatts of battery storage. This is more than 150 times California's current operating energy storage built since 2010.

Ironic that the batteries are now produced in Thailand not Mexico.
 
Does RFX's cost/kwh(do your own math) of storage give people here pause for thought as to how viable future expansion is for this company???
In the nexxt few years Lithium ion at the cell level should be edgeing to $60US/kwh...

Zinc bromine flow batteries have a longer life span and no risk of starting a fire unlike lithium.

Also check out depth of discharge, is a 10kw/hr lithium battery a 10kw/hr battery?
Or does depth of discharge worries make it in reality a 5kw/hr battery.
So many have so much to say, yet know so little IMO.
The other issue is end of life, the flow battery can easily be refurbished, which makes it ideal for domestic and static installations IMO.
For those who know little and say a lot, some reading to help get the knowledge in phase with the rhetoric, the article is in laymans terms so should be easy to follow. :xyxthumbs
I do hold.

Why depth of discharge matters in solar battery storage system selection

Depth of discharge (DoD) is one of the key figures to keep in mind when selecting batteries for a solar energy system. What is depth of discharge and how

Only 2% of lithium batteries get recycled,

Lithium is great for mobile applications, high density small size, but that isn't what is needed in a static situation where size doesn't matter.

What is needed there is depth of discharge and end of life renewal.
There is no point IMO, of paying $10k for a 10kw battery that really can only take a 50% depth of discharge and has to be replaced in 10 years.
Maybe @orr can explain the benefit?
 
Yes, hopefully RFX use their new income to accelerate the gen3 development and can produce a smaller cheaper flow battery system. (Maybe more competitive for domestic housing solar storage) ??
