World’s largest sodium-ion battery goes live | News

The world’s largest sodium-ion battery has been put into operation in Qianjiang, China’s Hubei province. Developers of the energy storage system say it can meet the daily electricity needs of 12,000 homes.

Rechargeable lithium-ion batteries are used in everything from mobile phones and electric vehicles to grid-scale energy storage. But with lithium in high demand, sodium-ion batteries have emerged as a potential cheaper alternative energy storage solution. Now, China’s state-owned energy company Datang Group has connected the world’s largest sodium-ion battery to the grid. The 50 MW/100 MWh energy storage system stores 10 times more energy than the world’s second-largest sodium-ion battery, which was connected to China’s southern power grid last year.

This marks the completion of the first phase of the Qianjiang project, which will eventually have twice the current storage capacity. Developers say the current facility will help reduce carbon emissions by 13,000 tons per year.
