Battery maker NGK Insulators has won an order to deploy 3.6MWh of its sodium-sulfur (NAS) batteries at Mongolia’s first solar-plus-storage energy storage system.
The Japanese-headquartered firm and the Ministry of Energy of Mongolia will deploy three 600kW NAS batteries for peak shifting and storage services, as the country weans itself from its reliance on coal power.
The operation is due to begin next spring in Uliastai, Zavkhan Province, Mongolia.
The system is part of the Upscaling Renewable Energy Sector Project, which aims to improve Mongolia’s energy security and reduce the amount of its carbon dioxide (CO2) emissions.
The order was received jointly by Japan’s JGC Corporation and MCS International, which is headquartered in Ulaanbaatar, Mongolia.
NGK says its 2V cells are capable of an energy density of 222Wh/kg and power density of 36W/kg with a 4,500 cycle-life.
To date, NGK has installed more 600MW NAS batteries and a total storage capacity of more than 4.2GWh globally.
