Abstract: At present, countries around the world are comprehensively laying out and developing the hydrogen energy industry chain based on their own development characteristics and technological advantages. Vigorously developing hydrogen energy is one of the important means for China to achieve the goal of "double carbon" and realize green transformation. China's hydrogen energy industry started late but has developed rapidly. In recent years, China has made great progress in hydrogen energy transportation, green hydrogen refining, and other aspects. With the development of the hydrogen energy industry from demonstration to large-scale application, the scale of green hydrogen storage and transportation continues to expand, and the safety issues of hydrogen storage and transportation are becoming increasingly prominent. The safety of hydrogen storage and transportation is a systematic issue that involves various aspects such as standard selection, plane layout, process design, automatic control, monitoring, equipment, and material selection. This article focuses on the scenario of normal temperature hydrogen storage and transportation in hydrogen energy storage and transportation engineering, and studies the material selection of hydrogen pipelines in different pressures and application scenarios in hydrogen energy storage and transportation engineering. Based on the characteristics of hydrogen, the current research status of hydrogen pipeline materials domestically and internationally, and the development needs of the hydrogen energy industry, suggestions for the material selection of normal temperature hydrogen pipelines at this stage are proposed.
