Preferred Bidders Named for CHN Energy's 22,000 Nm³/h Zhangye Hydrogen Project

Two companies have been named as preferred bidders for the procurement and construction (PC) contract covering the hydrogen-production facilities at the Zhangye Carbon-Neutral Industrial Base Wind-Solar-Hydrogen-Storage Integrated Project in Gansu Province, according to a notice published on November 5, 2026.

China National Chemical Engineering Fourth Construction Co., Ltd. ranked first with a bid of RMB 290.28 million, while Shaanxi Construction and Installation Group Co., Ltd. ranked second with a bid of RMB 297.00 million.

The project is located in the Circular Economy Demonstration Park within Zhangye Economic and Technological Development Zone, Gansu Province. It marks CHN Energy's first green-power-to-hydrogen project in the province.

The project will feature a 22,000 Nm³/h alkaline water electrolysis hydrogen-production system comprising 12 electrolyzers: three rated at 1,000 Nm³/h, eight at 2,000 Nm³/h and one at 3,000 Nm³/h.

Supporting infrastructure will include four 1,000 m³ spherical hydrogen storage tanks operating at 3.0 MPa and two 1,000 m³ spherical oxygen storage tanks operating at 2.0 MPa, along with utility and auxiliary systems.

The project will also include a pilot-scale water-electrolysis validation platform equipped with one 1,000 Nm³/h alkaline electrolyzer and one 500 Nm³/h proton exchange membrane (PEM) electrolyzer. A supporting hydrogen storage system will operate at 20 MPa, with an effective storage capacity of 800 Nm³.

Together, the main production system and pilot platform will comprise 14 electrolyzers.

The PC contractor's scope covers procurement of hydrogen-production equipment and materials not supplied by the project owner, civil construction, equipment installation and related project services. The contractor will also be responsible for safety, quality, schedule, costs and documentation throughout the procurement and construction processes.

Owner-supplied equipment, which is excluded from the contractor's procurement scope, includes:

Three 1,000 Nm³/h atmospheric-pressure, square-type electrolyzers;

Eight 2,000 Nm³/h atmospheric-pressure, square-type electrolyzers;

One 3,000 Nm³/h atmospheric-pressure, square-type electrolyzer;

One 1,000 Nm³/h pressurized electrolyzer;

One 500 Nm³/h PEM electrolyzer;

Seven power transformers for the hydrogen-production system; and

Twelve rectifiers for the hydrogen-production system.

Final equipment specifications and quantities will be subject to the procurement contract signed by the project owner.

The contract period is 15 months from its effective date. The actual construction start date will be determined by the project owner's notice. The project is required to enter operation by December 31, 2027, and pass completion acceptance by June 30, 2028.
