Aquion Energy, the saltwater battery maker, has cut a 10-year, 50% cost reduction target by eight years within the last five months.

The company now hopes to halve the cost of its products in as little as 48 months, instead of the decade it had estimated in June this year.

“We’ll probably achieve that within two years,” confirmed chief commercial officer Tim Poor.

“We’re a new chemistry with lots of optimisation as yet to be factored in by additional innovation and improvements to the basic battery chemistry design.”

A 50% reduction would bring the wholesale price of Aquion’s Cradle-to-Cradle-certified products down to around USD$200 per kWh.

Lithium-ion’s potential to dominate the stationary storage battery sector may be stronger than previously thought, according to the implications of a new study.

Research published last week by the analyst firm Bloomberg New Energy Finance (BNEF) shows a glut of second-hand lithium-ion (Li-ion) batteries from the auto industry could cut battery storage costs significantly.

By 2018, says Used EV batteries for stationary storage: second-life supply & costs, the cost of repurposing batteries for second-life applications could go down to as little as USD$49 per kWh.

This compares to a cost of roughly $300 per kWh for new batteries at the moment, and $160 for lowest-cost battery chemistries such as the zinc hybrid cathode technology being commercialised by Eos Energy Storage.

Given that BNEF expects around 10GWh of capacity from used electric vehicle batteries to be entering into the stationary storage market by 2025, second-life applications could deal a real blow to the prospects for non-Li-ion chemistries.
