China Datang Corporation, a state-owned power company, recently commissioned a 100 MWh energy storage station utilizing sodium-ion batteries in Hubei Province, central China, on June 30, according to battery provider Hina Battery on July 3.
The energy storage station can store 100,000 kWh of electricity in a single charge, sufficient to meet the daily demands of approximately 12,000 households.
Hina Battery stated that this is currently the world’s largest sodium-ion battery energy storage project, marking a new phase in the commercial operation of sodium-ion battery energy storage systems.
The energy storage station is the first phase of a 200 MWh project and comprises 42 battery compartments. According to Hina Battery, it can store 100,000 kWh of electricity in a single charge, discharge it during peak hours to meet the daily demands of about 12,000 households, and reduce CO2 emissions by 13,000 tons annually.

The company also stated that they are committed to the commercial application of sodium-ion battery energy storage technology, having completed the construction of the world’s first 100 kWh sodium-ion battery energy storage station in 2019.
Hina Battery also mentioned that they supplied a large quantity of sodium-ion energy storage batteries to the Southern China Power Grid at the end of 2023. The world’s first 10 MWh sodium-ion battery energy storage station utilizing these batteries was put into operation last May.
This battery storage station began operating on May 11 in Nanning, Guangxi, in southwestern China. Once the entire project is completed, it will be able to provide 73 million kWh of clean electricity annually, meeting the electricity demands of 35,000 households.
Regarding Hina Battery, the company was established in 2017 and launched sodium-ion batteries in the same year. On December 18, 2021, Hina Battery collaborated with two subsidiaries of the China Three Gorges Corporation and the Fuyang city government to build a large-scale mass production line for sodium-ion batteries.
On December 1, 2022, Hina Battery announced that the world’s first GWh-scale sodium-ion battery production line had produced its first batch of batteries.
Currently, lithium-ion batteries are predominantly used in electric vehicles and energy storage stations. Compared to lithium-ion batteries, sodium-ion batteries are considered to have a more abundant raw material reserve—nearly 1,000 times that of lithium—along with lower costs and better performance in low temperatures. Additionally, sodium-ion batteries are scalable, safer, and perform well in both extremely low and high temperatures. According to WoodMac, sodium-ion batteries are expected to partially replace LFP batteries in passenger electric vehicles and energy storage, reaching 20GWh by 2030.
In the global battery market, Chinese battery manufacturers also hold a dominant position. As of 2022, six Chinese companies were among the top ten battery manufacturers worldwide. Some Chinese electric vehicle manufacturers are also planning to develop their battery production facilities.
