青岛市氢能产业园输氢管道项目开工建设Construction of the Hydrogen Pipeline Project in Qingdao Hydrogen Energy Industrial Park Begins

On the morning of October 26, with the welding equipment sparked to start the first weld, the Qingdao Hydrogen Energy Industrial Park hydrogen transportation pipeline project officially commenced construction. This marks another new development in Qingdao's hydrogen energy industry since the city was selected as a national hydrogen energy comprehensive application pilot and officially launched related pilot work last week.

The Qingdao Hydrogen Energy Industrial Park hydrogen transportation pipeline project is a key infrastructure in the layout of the hydrogen energy industry in the West Coast New Area, invested and constructed by Qingdao Xinbo Holdings Group Co., Ltd. The project has a total investment of 5.7432 million yuan, mainly constructing a hydrogen transportation pipeline with a purification capacity of 10,000 standard cubic meters per hour (10000 Nm³/h) and a design pressure of 2.2 megapascals. As the first hydrogen transportation pipeline outside the park in Shandong Province, one end of the project connects to Jinneng Chemical (Qingdao) Co., Ltd., and the other end connects to the Huawang hydrogen refueling station within the Hydrogen Energy Industrial Park, with a total length of 886.41 meters.

"The project is expected to have a construction period of 60 days. Currently, the main construction of the hydrogen refueling station has been completed, and the site paving and outdoor pipeline installation are being accelerated. With the connection of the hydrogen transmission pipeline, the hydrogen refueling station is expected to be operational by the end of December," introduced Liu Shuai, General Manager of Huawang (Qingdao) Hydrogen Energy Technology Group Co., Ltd. After completion, the high-purity hydrogen produced from the hydrogen-rich tail gas of the PDH unit in the Jinneng Chemical plant using PSA purification technology will be directly supplied to the refueling station for hydrogen vehicles.

Hydrogen transportation has long relied primarily on long-tube trailers, and the processes of loading, unloading, round trips, and compression not only incur costs but also limit the continuity of hydrogen supply. Pipeline transmission directly connects the hydrogen production facility with the refueling terminal, eliminating the vehicle transfer step. It provides more stable hydrogen supply capacity and pressure, making it especially suitable for scenarios requiring high flow and continuous hydrogen consumption. Although the 886.41-meter pipeline length is not long, its significance lies in transforming the "production-storage-transmission-refueling" process from segmented connections into an integrated system, providing a physical channel for large-scale hydrogen flow within the park.

In recent years, the Qingdao Hydrogen Energy Industrial Park has adhered to high-level construction and operation. It has signed a total of 20 projects with a total investment of approximately 15 billion yuan. Five projects, including Penghua hydrogen fuel cell stacks, have been completed and put into production, continuously attracting high-quality industrial resources. The upstream of the industry chain involves by-product hydrogen purification, the midstream includes the manufacturing of core components such as fuel cell stacks, and the downstream covers hydrogen refueling stations and vehicle applications. A circular chain is forming within the park.

During the pilot phase, the Hydrogen Energy Industrial Park will accelerate the construction of integrated stations, verification and testing centers, and road network support, converting infrastructure into pilot scenarios to prepare for the large-scale application of hydrogen energy. From a single pipeline to a network, the density of infrastructure determines how far demonstration applications can go, which is also the practical reason why Qingdao moved first to advance hydrogen pipeline construction after being selected as a pilot city.
