Redflow targets 40% cut in battery storage costs by 2015  

RNE has an update on Redflow's flow battery technology - Redflow targets 40% cut in battery storage costs by 2015.

Redflow, a Brisbane-based developer of unique zinc-bromine “flow” batteries, says it is targeting a 40 per cent cut in the capital cost of energy storage systems by the end of next year.

In a market presentation released on Thursday, Redflow says it estimates the capital cost of its technology – developed originally at the University of Queensland –a t $875/kWh. This,is says, is comparable with some lithium-ion batteries, half the price of vanadium, and while expensive than some lead acid batteries, it will have greater applications.

However, full-scale manufacturing will commence later this year in a previously announced deal with global group Flextronics, and Redflow says this will lead to a cost reduction of 40 per cent by 2015. ...

Redflow’s core product is a “flow battery” that avoids some of the charging issues and limitations that affect other battery technologies, such as lead acid and lithium-ion. The company says the daily deep charge and discharge capability makes it ideal for storage and shifting of intermittent renewable energy, and managing peak load or supporting off-grid systems.
