August 4, 2022: Japan-based NGK Insulators is to deploy its NAS sodium sulfur battery technology combined with solar at manufacturing sites in the country to reduce CO2 emissions, the ceramics group said on August 1.

NGK will install 2.6MW of PV systems on rooftops with 1.2MWh of NAS battery rated capacity at two sites in Nomi in Ishikawa prefecture.

The battery will also be used as a backup power source if needed.

NGK said it expects the solar-storage system to reduce CO2 emissions by around 1,300 tonnes annually after it becomes operational in 2024.

NGK commercialized its sodium sulfur battery system some 18 years ago. In June 2019, NGK announced a sales partnership agreement with a subsidiary of German chemicals group BASF.
