A long-duration energy storage system using NGK’s sodium-sulfur (NAS) batteries has been commissioned by a subsidiary of German chemicals company BASF, which seeks out high growth opportunity businesses to work with. 

An order for 8.5MWh of iron electrolyte flow battery energy storage systems (ESS) has been received by US manufacturer ESS Inc from Enel Green Power’s Spanish arm. 

BASF is using NGK Insulators’ sodium sulfur batteries as its entry point into the energy market, with the German chemical company signing up as a sales partner to the Japanese manufacturer.
