A contract for a 100MW/400MWh all-vanadium flow independent energy storage station was signed in Changzhou, and the largest hydrogen storage demonstration project in the country has been awarded and signed.

Internationally, Huabao New Energy responded to U.S. tariff issues by stating that it has prepared sufficient inventory in advance, while Canadian Solar confirmed that it has included tariff protection clauses in its energy storage contracts. The U.S. Clean Energy Association announced a $100 billion investment to develop energy storage batteries, and the cause of a fire in a German balcony solar storage system has been identified, ruling out battery factors.

Production Capacity and Investment Highlights

Jiangsu Jieyuan’s 20GWh lithium battery manufacturing project aims for production in the third quarter. On May 5, the project, with a total investment of 5 billion yuan, achieved significant progress. The first factory has completed its pile foundation and basic construction, and is now awaiting the concrete compressive strength to meet standards, after which steel column installation will commence, aiming for production by the third quarter of this year.

Investment and Financing Update

On May 6, Zhongchuang Innovation and Suao Sensor announced that they have signed an agreement where Zhongchuang will acquire 156 million shares of Suao Sensor for 510 million yuan, granting Zhongchuang control over Suao Sensor. After the acquisition, Suao Sensor will become a subsidiary of Zhongchuang, which will hold 22.61% of its shares.

On the same day, CATL’s H-share issuance successfully passed the Hong Kong Stock Exchange’s listing hearing. The capital raised will be used to advance the construction of the first and second phases of its project in Hungary, operational funds, and other general corporate purposes. Meanwhile, Panasonic announced plans to close its solar and energy storage business to concentrate on areas with the most strategic impact, expressing confidence in solar and storage technology.

New Product Highlights

On May 7, at the 2025 European Smart Energy Expo in Munich, CATL unveiled the world’s first 9MWh high-capacity energy storage system, the TENER Stack. This system features high energy density batteries and a five-year zero degradation technology. Compared to traditional 20-foot energy storage systems, it boasts a 45% improvement in volume utilization and a 50% increase in energy density, capable of charging 150 electric vehicles.

Also on May 7, Xingwangda launched the NoahX 3.0, which features a 625Ah high-capacity energy storage cell. This product aims to advance high-density, low-cost, and intelligent energy storage systems, with global mass production scheduled for 2026. Shangen Electric presented its new household solar storage solution, which adheres to automotive-grade safety standards and includes six 335Ah high-quality cells.

Ruipu Lanjun also introduced its new 392Ah energy storage cell and PowtrixTM 6.26MWh energy storage system at the Munich exhibition, showcasing a variety of energy storage solutions for all scenarios.

Order and Performance Highlights

On May 7, Chuangneng New Energy and the UK’s Immersa signed a strategic cooperation agreement for 2.5GWh at the 2025 European Smart Energy Expo. The collaboration will focus on Chuangneng’s self-developed 5MWh battery prefabricated cabin, CORNEX M5. Additionally, BYD reported that in April 2025, the total installed capacity of its power and storage batteries reached approximately 26.478GWh, marking a historical high with a year-on-year growth of 110.83%.

Furthermore, Haishida Sodium Star announced it has received a procurement order for sodium-ion batteries from an overseas client, committing to a total procurement of no less than 1GWh over the next four years for residential, commercial, and telecommunications applications.

Haibosi’s first-quarter sales revenue approached 3GWh, and Nanfang Technology’s energy storage revenue for the same period exceeded 100 million yuan. Guoxuan High-Tech disclosed that it aims to ship around 63GWh in 2024, with energy storage accounting for about 35% of the total shipments.

Project Updates

On April 30, China General Nuclear Power Corporation’s 100MW/200MWh shared energy storage project in Yunnan was fully grid-connected.
