Redflow Energy Storage Solutions is planning to release a residential flow battery that observers believe could compete with lithium-ion batteries.
The Australian zinc-bromide flow battery maker is due to release full details of its 10-kilowatt-hour plug-and-play residential storage system at the end of March.
According to reports in the Australian press, the system is expected to cost between AUD$10,000 and $15,000 (USD$7,130 and $10,700) and will be competitive with the Tesla Powerwall on a cost-per-kilowatt-hour basis.
Redflow managed to halve the cost per kilowatt-hour of its batteries over the course of 2015, the Australian Financial Review reported.
The company is still finalizing the design of the product, which is being manufactured by the U.S. firm Flextronics. Redflow shareholders will get a discount on the first batteries produced.
Redflow declined to provide any further commercial details ahead of the March launch. One advantage the Redflow product could have over Tesla’s lithium-ion Powerwall is that the flow battery can be completely charged and recharged on a daily basis with no degradation in performance.
