China’s first large-scale lithium-sodium hybrid energy storage station, located in Wenshan, Yunnan province, is now operational. The station, run by China Southern Power Grid, leverages advanced sodium-ion batteries to address energy storage demands.
High-Capacity Technology and Storage Overview
The Baochi energy storage station integrates high-capacity sodium-ion batteries alongside mature lithium batteries. With a storage capacity of 800,000 kWh per day, it caters to the electricity needs of about 270,000 households. The energy station spans over 33,333 square meters and features more than 150 battery compartments and boost-converter compartments. Its maximum instantaneous output capacity reaches 200 MW, enabling optimal usage of renewable energy sources.
Why Sodium-Ion Batteries Stand Out
Sodium-ion batteries are gaining traction due to their abundant raw material reserves and low extraction cost, making them economically viable. In this station, the sodium-ion batteries boast six times faster response speeds compared to existing alternatives.
Wang Hui, head of the station, emphasized the advanced capabilities of sodium-ion batteries in balancing the volatility associated with new energy sources. Coupled with lithium batteries, this hybrid system supports stable energy delivery and efficient use of renewable power.
Enhanced Renewable Energy Integration
The station collaborates with over 30 wind and photovoltaic plants in the region. This setup ensures stable integration of renewables into the grid, facilitating seamless market transactions for clean energy. New energy sources from regions including Tibet, Xinjiang, Gansu, and Ningxia now experience improved stability and efficiency.
Wan Minhui, a researcher at Southern Grid’s energy storage unit, highlighted the system’s ability to flexibly adjust charging and discharging modes. This adaptability further promotes balanced energy distribution and consistent power delivery for renewable sources.
Contributions from Hina Battery
Hina Battery played a key role in providing the Sodium-ion Battery technology for this project. Known for their innovative energy solutions, Hina was established in 2017 and launched its first GWh-class Sodium-ion Battery production line in December 2022. Their high-capacity power sodium-ion batteries have received significant attention, particularly for their application in large-scale energy storage.
The Future of Sodium-Ion Batteries
While primarily used in energy storage systems like Baochi, sodium-ion batteries are also beginning to feature in Electric Vehicles, showcasing their versatility. This marks a significant milestone for the energy sector as their adoption continues to grow.
China’s dedication to renewable energy and advancements in energy storage technologies set a global precedent. The Baochi station exemplifies such innovation, reinforcing the country’s capabilities in achieving sustainable energy goals.
