Sodium sulfur (NAS) batteries produced by Japan’s NGK Insulators are being put into use on a massive scale in Abu Dhabi, the capital of the United Arab Emirates.

Should lithium-ion batteries be stored in sodium sulfur?

While many grid-scale battery projects around the world are currently being executed with lithium-ion batteries, in this instance, the use of sodium sulfur, allowing for six hours of storage, is “mandatory for thermal generation investment deferral”, the NGK spokesman said, with the peak demand period being shifted itself lasting around six hours.

How many NaS batteries are there in Abu Dhabi?

Sodium sulfur (NAS) batteries produced by Japan’s NGK Insulators are being put into use on a massive scale in Abu Dhabi, the capital of the United Arab Emirates. The company’s battery systems have been deployed across 10 locations – 15 systems in total – adding up to 108MW / 648MWh in total, with each system able to store energy for six hours.

What is a standard NaS battery container?
