4 FAQs about Sodium-sulfur battery energy storage project

Are sodium batteries a good choice for energy storage?

Much of the attraction to sodium (Na) batteries as candidates for large-scale energy storage stems from the fact that as the sixth most abundant element in the Earth’s crust and the fourth most abundant element in the ocean, it is an inexpensive and globally accessible commodity.

What is a sodium-sulfur battery?

Sodium-sulfur (NaS) batteries are a promising energy storage technology for a number of applications, particularly those requiring high-power responses [11,21]. It is composed of a sodium-negative electrode, a sulfur cathode, and a beta-alumina solid electrolyte that produces sodium pentasulfide during the discharge reaction .

Who makes sodium sulfur batteries?

Utility-scale sodium–sulfur batteries are manufactured by only one company, NGK Insulators Limited (Nagoya, Japan), which currently has an annual production capacity of 90 MW . The sodium sulfur battery is a high-temperature battery. It operates at 300°C and utilizes a solid electrolyte, making it unique among the common secondary cells.
