Development of standards for liquid hydrogen in China

Abstract

Liquid hydrogen is important to long distance hydrogen transportation and development of heavy-duty vehicles, etc. China starts to deploy liquid hydrogen since 2020. To support the development of liquid hydrogen, three national standards for liquid hydrogen have been published. In this paper, national standards for liquid hydrogen specification, production, storage and transportation, and hydrogen fueling station are reviewed. Compared to USA, standards for liquid hydrogen in China are insufficient. It is important to establish a complete standard system for liquid hydrogen to better support the commercial, safe use of liquid hydrogen.
