Evolution in Hydrogen Safety Activities, Regulations, and Standards in China Over the Last Decade

Hydrogen represents one effective solution for China to develop economy in a sustainable way, for its characteristics of unlimited supply, emissions reduction, and high energy efficiency. There has been an ever-increasing interest in the study of hydrogen safety in China over the last decade, driven by the development of hydrogen energy. First, activities related to hydrogen safety in China were reviewed, including the investigations of temperature rise during hydrogen fast filling, fire test for on-boardhydrogen storage tank, consequence evaluation of hydrogen release and explosion, safety distance, and so on. Second, a systematic overview of Chinese regulations and standards for hydrogen technology was presented. The regulations and standards on hydrogen safety were described in detail. Some important on-going activities related to hydrogen safety were introduced subsequently. Finally, suggestions on further studies on hydrogen safety and development of relevant standards were proposed.
