China Deploys First Large-Scale Sodium-Ion Battery Energy Storage System
Datang Hubei Energy Development Co., Ltd. (Datang Hubei Energy) recently announced that its large-scale sodium-ion battery energy storage systemhas been recognized as one of the Top 10 Technological Innovations in the Energy Industry for 2024 by the National Energy Administration (NEA). A key part of this achievement is the Datang Qianjiang Sodium-Ion Energy Storage Station, which marks a significant milestone in the commercialization of sodium-ion battery technology.
Sodium-ion batteries are emerging as a key energy storage technology for next-generation power systems, offering cost advantages, abundant raw materials, and a secure supply chain. This project represents the world’s first large-scale commercial deployment of sodium-ion energy storage technology.
The system features a fully self-developed energy management platform that integrates AI-driven data analysis and image recognition for early safety warnings and intelligent operations. With an efficiency of over 80%, the project has achieved breakthroughs in high-capacity sodium-ion battery technology, system integration, and safety controls, all developed with independent intellectual property rights.
According to Datang Hubei Energy, the project helps balance electricity supply and demand through peak shaving and valley filling, enhancing grid flexibility and renewable energy consumption. Since its commissioning on June 30, 2024, the system has completed 147 charge-discharge cycles by the end of the year, significantly improving regional power stability and reliability.
