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
