Construction of Guizhou’s 99 million yuan green hydrogen project kicks off 2026-02-04 On February 2, the China Tendering and Bidding Public Service Platform issued a tender announcement for the Wind-Hydrogen Green Hydrogen Zero-Carbon Smart Park project based in Duyun, Guizhou, marking the official start of the project’s implementation phase. It is understood that this project was built by Wind-Hydrogen Energy (Guizhou) Technology Co., Ltd., with an investment of around 99 million yuan. The project is located at the intersection of Yunlong Avenue and the southern section of Qishan Avenue in the Duyun Economic Development Zone in Guizhou, covering an area of 72,334 square meters. Its planned production capacity is 10,400 tons of green hydrogen per year, with a purity level of ≥99.999%. The facilities included in the project are a green hydrogen factory, storage and transportation areas, a hydrogen energy testing center, and a comprehensive energy station. The hydrogen production plant with an annual output of 10,400 tons of hydrogen is divided into five hydrogen production units. The first unit includes 5 sets of electrolyzer equipment with a capacity of 1,000 Nm³/h, 5 sets of gas-liquid separation equipment with a capacity of 1,000 Nm³/h, and 1 set of purification equipment with a capacity of 5,000 Nm³/h. The second and third units each contain 4 sets of electrolyzer equipment with a capacity of 1,000 Nm³/h, 1 set of gas-liquid separation equipment with a capacity of 4,000 Nm³/h, and 1 set of purification equipment with a capacity of 4,000 Nm³/h. The fourth unit (backup unit) includes 6 sets of electrolyzer equipment with a capacity of 1,000 Nm³/h, 6 sets of gas-liquid separation equipment with a capacity of 1,000 Nm³/h, and 1 set of purification equipment with a capacity of 6,000 Nm³/h. The fifth unit is a 200 Nm³ PEM (test unit, located in the hydrogen production workshop). The first three hydrogen production units are included in the capacity calculation, resulting in a total hydrogen production rate of 14,560 Nm³/h; the purity of the produced hydrogen is 99.999%. The last two units are standby units and are not taken into account in the capacity calculation. According to the available information, the constructor will begin site preparation in June 2025, and the environmental impact assessment documents will be submitted for consideration in January 2026; the project construction is progressing steadily in accordance with the planned schedule.
