The tender for the PC turnkey contract of the Inner Mongolia Huadian Damao Banner 1 million kW wind and solar power-to-hydrogen integrated project has recently been initiated. The tender is divided into Section I and Section II, with the project site located in Damao Banner, Baotou City, Inner Mongolia Autonomous Region.
According to the tender announcement, the project is the first phase of the Inner Mongolia Huadian Damao Banner 1 million kW wind and solar power-to-hydrogen project by Huadian Huayang Company. The first phase will build a 1 million kW new energy power generation scale, including 700 MW of wind power and 300 MW of PV. The wind power segment plans to install 70 wind turbine generators each with a single-unit capacity of 10 MW, while the PV segment is expected to adopt 710 Wp to 740 Wp half-cell, double-glass N-type battery modules.
The project will also include supporting construction of one 100 MW/200 MWh LFP battery ESS power station, two 220 kV step-up substations, as well as access roads, collector lines and other equipment and facilities, forming a coordinated operation system integrating wind power, PV, energy storage and hydrogen production.
For the hydrogen production segment, the project plans to construct 83 units of 1000 Nm³/h, 1 unit of 2000 Nm³/h and 1 unit of 3000 Nm³/h alkaline electrolyzer hydrogen production systems, totaling 85 electrolyzers, with an annual hydrogen production of about 47,000 mt. For hydrogen storage, the project will deploy 25 units of 2000 m³ hydrogen spherical tanks, providing a hydrogen storage capacity of about 650,000 Nm³, along with supporting facilities such as one 220 kV general step-down substation for hydrogen production.
In terms of the schedule, the overall project is planned to be put into operation on August 25, 2027. Among them, Section I has a tentative construction period of 300 days, and Section II has a tentative construction period of 360 days. The specific start time is subject to the bid inviter's written notice, and the end time is subject to the project's completion acceptance, while in principle meeting the group company's requirements for the date of reaching the standard and being put into production.
This tender is divided into two sections. Section I involves the 617 MW wind-solar power PC turnkey contract works, including 450 MW wind power, 167 MW PV, one 220 kV step-up substation, and one 100 MW/200 MWh electrochemical energy storage project. The scope of this section covers the procurement of equipment and materials except for those supplied by Party A, as well as construction, installation, commissioning, and grid-related testing within the wind power, PV, energy storage and substation areas.
Section II covers the 383 MW wind-solar power PC turnkey contract works and the construction turnkey contract works for the hydrogen production station and 220 kV general step-down substation, including 250 MW wind power, 133 MW PV, and related construction contents of the hydrogen production station and general step-down substation. For this section, apart from the equipment supplied by Party A, it also includes the procurement of relevant equipment and materials, as well as construction, installation, and commissioning within the scope of wind power, PV and hydrogen production station works.
According to the announcement, the project does not accept consortium bids.
As a wind and solar power-to-hydrogen integrated project, the Damao Banner project systematically integrates new energy power generation, energy storage regulation, electrolytic water hydrogen production, and large-scale hydrogen storage. Upon completion, the project is expected to further enhance Inner Mongolia's green hydrogen supply capacity, providing support for the large-scale consumption of renewable energy and the development of the hydrogen-based energy industry.
