Standards are essential to establish a market-receptive and safe environment for commercial hydrogen equipment and systems. A review of ISO, IEC and Chinese national hydrogen standards is presented in this paper. China has a larger number of hydrogen national standards than ISO and IEC, involving terminology, hydrogen fuel quality, hydrogen safety, construction, production and purification, storage, transportation and fuelling, applications, and testing. ISO hydrogen standards are mainly specialized in hydrogen fuel quality, safety, production, hydrogen fuelling station, and testing. IEC hydrogen standards are mainly specialized in fuel cell safety, applications and testing. Hydrogen standard system is now imbalanced and insufficient for China. We should pay much more attention on drafting standards for hydrogen production, storage, transportation and fuelling. |
