Natron Energy to build gigawatt-scale sodium-ion battery plant in North Carolina
The new planned manufacturing facility will produce 24 GW of Natron’s sodium-ion batteries annually. Natron says its batteries outperform lithium-ion batteries in power density and recharging speed, do not require lithium, cobalt, copper, or nickel, and are non-flammable. The plant will be the first double-digit GW sodium-ion plant in the USA.
50MW/100MWh Sodium-ion ESS goes online in China with string PCS MV stations
In the Hubei province in China, 50MW/100MWh is just the first phase of the sodium-ion battery energy storage system (BESS) project spearheaded by Sineng Electric. The project should eventually have a storage capacity of 100MW/200MWh. The initial capacity has already been connected to the grid and begun operations, able to supply power to around 12,000 households for a whole day.
