China Southern Energy Grid Power Storage, the power storage division of China Southern Energy Grid, has commissioned a ten MWh sodium-ion battery storage station in Nanning, southwestern China.
The corporate mentioned the power is the primary large-scale mission of its variety in China, and the primary section of a 100 MWh world mission.
“China has put into operation the primary large-scale storage station with sodium-ion batteries, marking a brand new period for low-cost batteries for large-scale use,” mentioned China Southern Energy Grid in an announcement.
The ten MWh sodium ion battery power storage station options 210 Ah sodium ion battery cells that may be charged to 90% in 12 minutes, in keeping with the corporate. The system consists of twenty-two,000 cells.
“In contrast with lithium-ion batteries, the uncooked materials reserves of sodium-ion batteries are considerable, simple to extract, low price and have higher efficiency at low temperatures, in order that they have apparent benefits for giant scale power storage,” the corporate said. “With these batteries, storage price will be diminished by 20% to 30%, and the associated fee per kilowatt-hour of electrical energy could also be diminished to CNY 0.2 ($0.0276).”
