China’s first large-capacity sodium-ion energy storage station saw its Phase II expansion project go into operation on Wednesday in Nanning, south China’s Guangxi, bringing the station’s total capacity to 50 MW.

The facility can now complete up to 600 charge-discharge cycles per year, enabling the additional consumption of about 30 million kWh of wind and solar power annually, enough to meet the annual electricity demand of around 20,000 households and equivalent to reducing CO2 emissions by 13,500 tonnes.

    I’m really excited for sodium-ion batteries to mature. Sodium is much more plentiful and less harmful to acquire than lithium, with near limitless amounts of it in the crust and the oceans. They also operate in a broader temperature range and can theoretically last for even more cycles. The only real downside is its lower energy density, which is improving and isn’t too important for grid-scale storage. Scale is really the biggest issue right now, and fortunately scaling up is something China is quite good at doing.
