en.Wedoany.com Reported - The 20GWh semi-solid-state battery production base and grid-forming underground energy storage power station project of Wocheng New Energy has officially landed in Zhangwan District, Shiyan City, Hubei Province, with a groundbreaking ceremony scheduled for June 17.
The project focuses on the research, development, and production of high-safety, long-life, underground high-end energy storage systems. With a planned total capacity of 20GWh, it encompasses two core segments: the production of semi-solid-state energy storage cells and the demonstration of a grid-forming underground energy storage power station. The project will establish a production base integrating intelligent manufacturing and technological innovation, creating a hub for China's underground energy storage system solutions.
The core technologies of the project include semi-solid-state energy storage technology and grid-forming underground energy storage power stations. The semi-solid-state electrolyte technology inherits the high safety of solid-state batteries while balancing engineering feasibility and cost controllability. Compared with traditional liquid lithium batteries, it significantly improves thermal stability, effectively suppressing thermal runaway; extends cycle life to meet the long-term operational needs of energy storage power stations; and balances energy density and rate performance, making it suitable for grid-level frequency regulation and peak shaving scenarios. The grid-forming underground energy storage power station is China's first large-scale demonstration: core equipment is placed underground, while the above-ground area can be restored to greenery or lightweight photovoltaic carports, saving land resources and reducing visual impact. The grid-forming control actively supports grid voltage and frequency, enhancing new energy integration capacity and addressing stability challenges of high-proportion renewable energy grid connection. With a high protection level, it adapts to various climatic conditions and ensures safer operation and maintenance.
In terms of industrial significance, the project will aggregate upstream and downstream resources, covering positive and negative electrode materials, electrolytes or solid electrolytes, separators, as well as BMS, PCS, system integration, and power station operation and maintenance, forming a complete industrial ecosystem. Previously, there was no large-scale manufacturing of high-end energy storage cells in Shiyan City and its surrounding areas. This project directly fills a critical gap in the industrial chain. The underground energy storage power station will participate in regional grid regulation, improving green electricity integration capacity. Additionally, the project will establish an energy storage industry research institute and a training base to cultivate new energy technology talent for the region.
