Research on standards and standard system of hydrogen pipeline in China

Abstract

Pipeline hydrogen transport is one of the main technical paths to achieve large-scale storage and transportation of hydrogen energy, and standards are important technical support for pipeline hydrogen transport applications. China’s hydrogen pipeline construction started late, and a relatively complete hydrogen pipeline standard system has been established in the world, but China’s hydrogen pipeline standard system has not been established, the lack of key technical standards and other problems. This paper investigates the current situation of hydrogen transport pipeline standards and the applicability to China. A standard system is preliminarily constructed for hydrogen transport pipelines, including 6 sub-systems and 23 technical standard fields. Some suggestions are put forward for the development of China’s hydrogen pipeline standardization.
