The 25th National "Safety Production Month" in 2026. Everyone pays attention to safety and everyone will investigate and rectify potential risks on an emergency basis -------------------------------------------------- June 26,* * The Pipeline Group Hydrogen Energy Storage and Transportation Technology Exchange Conference was held in Beijing. The meeting officially released the hydrogen pipeline engineering technical plan and complete set of standards, establishing a complete technical specification and standard system for the access, storage, transportation, and delivery of hydrogen pipeline transportation, filling the gap in my country's long-distance, large-scale hydrogen pipeline transmission complete set of technologies and standards, and marking the key leap from single-point technical research to systematic application of my country's long-distance hydrogen pipelines. The complete set of technologies for hydrogen pipeline transmission projects released at the conference closely follows the core engineering needs of new hydrogen pipelines, hydrogen doping assessment and transformation of natural gas pipelines, hydrogen access and delivery, operation management, repair and maintenance, safety management and integrity management. It is the first time to build a technical map of hydrogen pipeline transmission projects, which can be applied to new hydrogen pipelines and in-service natural gas. Six sub-scenarios under the two main application scenarios of pipeline transformation/hydrogen doping transportation, the simultaneously released standard system and complete set of enterprise standards, comprehensively cover key aspects of the entire process of hydrogen pipeline materials, design, construction, safety, operation and maintenance, etc., and provide authoritative and standardized technical basis and standard support for the pilot demonstration and large-scale promotion of hydrogen pipeline transmission projects. As a key link in the "production, storage, and transportation" of hydrogen energy, pipeline transportation is the core path to achieve large-scale, long-distance, and highly reliable transportation of hydrogen. It is also an important part of the construction of a new energy "quality and energy network" and plays a fundamental supporting role in improving the new energy system and promoting the large-scale implementation of the hydrogen energy industry. * * Relying on the resource advantages of "One Nationwide Network", the Pipeline Network Group continues to promote hydrogen energy pipeline transmission technology research and industrial layout. It has now formed comprehensive capabilities integrating core technologies, standard systems, and test platforms.: Overcome the problem of hydrogen embrittlement in high-pressure pure hydrogen transportation and develop the country’s first 10 MPa X60 steel grade special hydrogen transportation pipe ； Build the 10 MPa pipeline hydrogen doping and transportation test platform with the most complete functions and the highest pressure level in China, and clarify the safe hydrogen doping boundary of in-service pipelines ； Independently developed core equipment such as leakage monitoring systems ； Build enterprises, industries, * * , international four-level linkage standard system, and established a number of ISO international standards.
