June 13, 2019: Japanese firm NGK Insulators, the first firm to commercialize sodium sulfur batteries in scale, and BASF New Business, a wholly-owned subsidiary of the German chemical group BASF, announced on June 11 the conclusion of a sales partnership agreement.

The move is timely as system developers are increasingly looking for longer duration energy storage.

NGK commercialized its sodium sulfur battery system some 15 years ago. The firm says it has delivered NAS battery systems to about 200 locations worldwide with a total output of more than 560MW and a storage capacity of 4GWh.

The partnership allows BASF another entry point into the energy market and also allows NGK the ability to use BASF’s worldwide distribution network, which should allow it to achieve higher market penetration.

“Based on our technical expertise gained by own developments in recent years, sodium-sulfur technology fits ideally to the requirements of the emerging market for long-duration energy storage systems,” says Frank Prechtl, director business build-upE-power-management of BASF New Business

“The NAS battery from NGK enables BASF to enter the energy market and offer customers a reliable, proven solution.”  “The NaS battery system has a range of positive features, including larger capacity, higher energy density and longer life compared to other battery technologies,” says NGK.  “These features are beneficial for stationary applications ‒ in contrast to lithium-ion batteries, for example, which are suited to deliver high power over shorter periods.”
