Sodium-Sulfur Batteries

NGK Insulators is known-worldwide for the development of sodium-sulfur batteries in cooperation with TEPCO.[5] NGK's NaS battery systems are being used worldwide, primarily in Japan and the United States.[6]

NGK Insulators markets its NaS batteries for use as grid storage (especially for use in conjunction with renewable energy sources such as wind and solar). The battery systems can be used for both peak shaving, load leveling, emissions reductions, and as emergency power supplies. The "typical system" (as defined by NGK) is composed of 40 50-kW units for a total system capacity of 12,000 kWh.[5]
