June 30, 2024 – The first phase of the Datang Hubei 100 MW / 200 MWh Sodium-Ion New Energy Storage Power Station Technology Innovation Demonstration Project has been completed and connected to the grid, with an initial operational capacity of 50 MW / 100 MWh. The sodium-ion battery cells for the project were supplied by HiNa Battery. This represents the world's largest sodium-ion battery energy storage project to date, marking a new stage in the commercial operation of sodium-ion battery energy storage systems.

The station's energy storage system comprises 42 battery storage containers and 21 power conversion system (PCS) units, supported by a dedicated 110 kV booster station. Once operational, a single full charge can store 100,000 kWh of electricity. Releasing this stored energy during peak grid demand can meet the daily electricity needs of approximately 12,000 households. Annually, it is expected to reduce carbon dioxide emissions by 13,000 tons, demonstrating significant economic and social benefits.

Sodium-ion batteries are a prime example of new quality productive forces. They can fundamentally address the potential supply chain vulnerabilities arising from the limited and uneven global distribution of lithium resources (China holds only about 6.3% of global reserves). This technology serves as a critical enabler for building China's new power system and represents an important direction for cultivating strategic emerging industries. Datang Hubei, positioned at the forefront of technology and market trends, has demonstrated courage in exploring new technological paths and a willingness to make breakthroughs. Through in-depth research, careful technical evaluation, and dedicated efforts during construction, the project exemplifies the innovative spirit and sense of responsibility inherent in a central state-owned enterprise.

HiNa Battery is committed to the commercial application of sodium-ion battery energy storage technology. Key milestones include completing the world's first 100 kWh sodium-ion battery energy storage station demonstration in 2019, successfully commissioning the world's first 1 MWh sodium-ion battery energy storage system in 2021, and completing the batch delivery of sodium-ion battery cells to China Southern Power Grid by the end of 2023. This latter delivery supported the world's first 10 MWh sodium-ion battery grid-side energy storage station, which was officially connected to the grid in May this year. The commissioning of Datang Hubei's world-first 100 MWh sodium-ion energy storage station represents another significant milestone in the technological development and commercial operation of sodium-ion battery energy storage.

Looking ahead, HiNa Battery will continue to collaborate closely with upstream and downstream partners. Staying true to its original aspirations and forging ahead with determination, the company will accelerate the commercialization process of sodium-ion batteries and contribute its expertise to the new energy industry.

This project also received support from the National Key Research and Development Program of China.
