The first phase of Datang Group’s 100 MW/200 MWh sodium-ion energy storage project in Qianjiang, Hubei Province, was successfully connected to the grid on July 2, 2024. This milestone marked a significant achievement for China’s state-owned power generation enterprise and is a testament to its commitment to clean energy.
The project, which is part of the Datang Hubei Sodium Ion New Energy Storage Power Station, consists of 42 battery energy storage containers and 21 sets of boost converters. It utilizes large-capacity sodium-ion batteries supplied by China’s HiNa Battery Technology and is equipped with a 110 kV transformer station.
With this achievement, Datang Group has become the world’s largest operator of sodium-ion battery energy storage systems. Previously, the largest operational sodium-ion system was China Southern Power Grid’s Fulin 10 MWh BESS project in Nanning, southwestern China. This project also uses HiNa Battery cells and is part of a larger 100 MWh project.
The success of this project highlights the growing importance of sodium-ion batteries as an alternative to traditional lithium-ion batteries for energy storage applications. Sodium-ion batteries offer several advantages over lithium-ion batteries such as longer cycle life, higher energy density, and faster charging times. They are also more environmentally friendly as they do not contain any rare earth metals like lithium-ion batteries do.
Datang Group has been at the forefront of developing and deploying new technologies for clean energy production and storage. With this successful completion of their latest project, they continue to set new standards in the industry and contribute to China’s vision for sustainable development.
