JSE-listed Reunert Group subsidiary Reutech and newly formed BlueNova has introduced lithium-iron yttrium phosphate (LiFeYP04) batteries to the market, noting that it would be a good alternative to ageing lead-acid batteries.
BlueNova CEO James Verster told delegates at the launch that the batteries would be available to the market at $550/kWh or R9 000/kWh.
“These batteries are guaranteed to last more than ten years, which translates into a fixed cost of energy storage of less than R2/kWh over that period,” he said.
Verster further explained that the introduction of the batteries, which ranged from 12 V to 800 V direct current, was specifically aimed at replacing all lead-acid batteries in Southern Africa, with a need for these storage solutions in residential, industrial and utility-scale applications.
“These are very exciting times for energy storage . . . the lithium battery supersedes all expectations of lead-acid batteries. We are not looking at a new market, like the electric vehicle is seeking, but we are looking at people who are already spending money . . . in the R2.5-billion local static energy storage industry.”
Verster further noted that, besides being 100% environment-friendly, the LiFeYPO4 battery system offered greater safety than the traditional lead-acid battery, as it did not leak or give off gas and required zero maintenance.
