China's 195-km Damao Banner–Baotou Hydrogen Pipeline Completes Main Construction

On October 21, 2026, the nitrogen purging operation for the long-distance hydrogen pipeline connecting Damao Banner and downtown Baotou was successfully completed, marking the completion of the main construction work on what is described as China’s first high-pressure, long-distance green hydrogen pipeline.

The Damao Banner–Baotou Hydrogen Pipeline is a key project under the first batch of hydrogen energy pilot projects designated by China’s National Energy Administration. Stretching approximately 195 kilometers, the pipeline is designed to meet Baotou’s industrial hydrogen demand once commissioned and provide infrastructure support for future hydrogen supplies to the Beijing-Tianjin-Hebei region, as well as Shaanxi, Ningxia, Liaoning and other areas.

The pipeline starts at the initial station in Barun Industrial Park (Chemical Industry Cluster) in the Bayan Obo Mining Area. Running generally from north to south, it passes through the Bayan Obo Mining Area, the New Industrial Park, Guyang County, Urad Front Banner and Kundulun District in Baotou, where the terminal station is located.

The pipeline has a total length of approximately 195 km, a design pressure of 6.3 MPa and a nominal diameter of DN457. Its designed annual hydrogen transmission capacity is 100,000 tonnes.
