Abstract:

The materials used for hydrogen energy storage and transportation equipment are the foundation for the large-scale application of hydrogen energy, and standards are the prerequisite for correct material selection and safe use. At present, China is vigorously promoting material research and development, standard formulation, and other aspects in this field. However, due to the limited research data and engineering application experience in this area, it is necessary to refer to and draw lessons from relevant technical information from abroad. The relevant technical requirements of the main foreign standard specifications for hydrogen energy equipment materials, and the regulations on the compatibility and sensitivity of metal materials for hydrogen energy storage and transportation equipment with hydrogen were elaborated, and the future development of materials for hydrogen storage equipment was envisaged, to assist the technological progress of research and development, standard formulation, and engineering application of hydrogen energy materials in China.

Key words: hydrogen energy equipment, metal material, high pressure hydrogen storage, low temperature hydrogen storage, pipeline hydrogen transportation, compatibility, HEE index, fracture mechanics

摘要：

氢能“储运输”装备用材料是氢能规模化应用的基础，标准是规范装备选材和保障装备安全使用的前提。目前，国内在该领域的材料研发、标准编制等方面正在大力推进中。但由于在这方面的研究数据和工程应用经验较少，需要参考和借鉴国外的相关技术资料。文中就氢能装备用材主要国外标准规范的相关技术要求、氢能“储运输”装备用金属材料与氢相容性、敏感性的规定以及未来储氢装备用材料技术发展展望进行综合性阐述，助力国内氢能用材的研发、标准编制和工程应用的技术进步。
