Dengkou - Shanghai Temple 553km Green Hydrogen Pipeline Project Initiates Stability Assessment Public Announcement, Total Investment 5.65 Billion, Boosting Inner Mongolia Green Hydrogen Pipeline Network Layout

On December 9, the People's Government of Otog Front Banner issued the "Public Announcement on the Social Stability Risk Assessment of the Dengkou-Shanghaimiao Green Hydrogen Pipeline Project," marking the entry of this large-scale green hydrogen transmission pipeline project spanning multiple leagues and cities into the social stability risk assessment stage. The project is an important component of the "One Main Line, Dual Rings, Four Outlets" green hydrogen pipeline network plan in Inner Mongolia. The information source is the People's Government of Otog Front Banner.

I. Project Core Construction Indicators and Pipeline Network Layout

1. Overall Scale: The project involves four areas: Bayannur City, Wuhai City, Ordos City, and Alxa League. The total pipeline length is 553 km, with a design pressure of 6.3 MPa and a design transmission capacity of 500,000 mt/year. The total investment is approximately 5.65 billion yuan (including tax). The construction unit is Inner Mongolia Menghxi Western Pipeline Network Co., Ltd.

2. Pipeline Network Structure: The project adopts a "One Main Line, Two Branch Lines" layout model:

• The main line is the Urat Rear Banner-Dengkou-Shanghaimiao Green Hydrogen Pipeline, with a length of 421 km and a pipe diameter of DN600, equipped with 6 stations and 12 valve chambers;

• Branch Line 1 is the Alxa Aolunbulage-Dengkou Green Hydrogen Pipeline, with a length of 92 km and a pipe diameter of DN400, equipped with 1 station and 3 valve chambers;

• Branch Line 2 is the Ordos Qipanjing-Wuhai Low-Carbon Park Green Hydrogen Pipeline, with a length of 40 km and a pipe diameter of DN300, equipped with 1 station and 1 valve chamber.

II. Content of the Social Stability Risk Assessment Public Announcement

This public announcement aims to widely solicit public opinions on the project. The core matters for solicitation include the public's attitude towards the project construction, potential social stability risks that may arise from the project, and related opinions and suggestions. The announcement sets a 15-day feedback period for opinions. The public can provide feedback to the construction unit or the evaluation unit through designated contact methods:

• Contact person for the construction unit, Inner Mongolia Menghxi Western Pipeline Network Co., Ltd.: Li Jian, Tel: 18004815147;

• Contact person for the evaluation unit, Inner Mongolia Menggeli Zhiye Group Co., Ltd.: Han Xiaofeng, Tel: 13294718666.

III. Strategic Significance of the Project for the Industry

This project is another large-scale green hydrogen pipeline project announced in Inner Mongolia following the Ar Horqin-Ningcheng Green Hydrogen Pipeline Project. It will accelerate the implementation of the "One Main Line, Dual Rings, Four Outlets" green hydrogen pipeline network plan in Inner Mongolia. Combined with the previously filed Shanghaimiao-Ningdong (Ningxia Section) Green Hydrogen Pipeline Project on September 29, it will form a regional green hydrogen transmission network in the future. This network will not only directly supply the Ningdong Energy Base but also radiate to surrounding areas, helping to build a "green hydrogen + chemical" industry chain, achieve efficient conversion of wind and solar power resources, and provide key infrastructure support for regional energy structure transformation and the realization of the "dual carbon" goals.
