5000公里输氢管道规划倒逼标准体系完善

Core Viewpoint - The article emphasizes the importance of hydrogen pipeline technology in the development of green hydrogen projects in China, highlighting the need for standardized regulations and technological advancements to facilitate large-scale hydrogen transportation and storage [2][6]. Summary by Sections Hydrogen Pipeline Development - As of 2024, China has constructed approximately 150 km of pure hydrogen pipelines and over 500 km of hydrogen-blended pipelines, with plans to build over 5000 km by 2030 [2]. - The article outlines various ongoing hydrogen pipeline projects, including a 1132 km pipeline from Inner Mongolia to the Beijing-Tianjin-Hebei region and a 972.7 km pure hydrogen pipeline, which is the largest in the world in terms of diameter and capacity [4][5]. Standards and Regulations - Since 2024, China has been actively developing national and group standards for hydrogen pipelines, addressing the previous lack of targeted standards and relying on international references [2][5]. - Key standards include the "Hydrogen Transport Pipeline Integrity Management Specification" and the "National Standard for Steel Pipes for Hydrogen Storage and Transport," which aim to fill the regulatory gaps in the hydrogen energy sector [5][6]. Challenges and Future Outlook - The article identifies several challenges facing the hydrogen pipeline industry, including the low domestic production rate of critical equipment, the need for improved compatibility between hydrogen and pipeline materials, and the fragmented nature of current projects [6]. - It suggests that successful demonstration projects should serve as testing grounds for advancing standards and technology, ultimately enabling the transition from planning to actual implementation of green hydrogen infrastructure [6].
