BASF Stationary Energy Storage GmbH, a wholly owned subsidiary of BASF and NGK, has released what it calls “an advanced container-type NAS battery”, NAS Model L24.
It is said to offer a significantly lower degradation rate than previous designs, achieving 1% per year, thanks to reduced corrosion in the battery cells. It also has an improved thermal management system, enabling longer continuous discharge (eg 6 hours for a discharge at 200 kW-dc per L24 unit).
These improvements allow projects to be implemented using significantly fewer NAS battery containers and with lower maintenance costs, say the developers, also noting that “the new concept complies with the latest safety standards for energy storage installations, such as UL1973 and UL9540A.”
