Pipeline transportation is recognized as the most efficient and economical large-scale hydrogen transportation currently in use. This study offers a summary and synthesis of the current research on key issues including the compatibility of hydrogen pipeline materials, hydrogen leakage and monitoring, integrity management systems, and the lack of relevant standards and codes. The results indicate the following:the mechanism behind hydrogen-induced failure in typical pipeline steels under high-pressure hydrogen environments is not yet fully understood. It is necessary to investigate the degradation patterns of mechanical properties for different grades of steel under hydrogen environments and analyze the factors affecting hydrogen embrittlement susceptibility of steel. Secondly, hydrogen pipelines are more prone to leakage. Identifying the specific causes of hydrogen leakage in pipelines and associated equipment is imperative, alongside enhancing hydrogen leak monitoring technologies. Thirdly, there is a noticeable lack of integrity management systems for hydrogen pipelines. Integrating the effects of hydrogen into both risk assessments and integrity evaluations is vital for refining the techniques used to manage the integrity of hydrogen pipelines. Fourthly, leveraging existing hydrogen pipeline specifications to provide support for the integrity management of hydrogen pipelines and to foster the development of standards and codes for pipeline integrity management is crucial. The conclusions drawn can provide reference for the development of integrity management system for hydrogen pipelines.
