Abstract: Liquid hydrogen has the characteristics of high storage density and energy. However,limited by the physical properties of liquid hydrogen,its storage and transportation technologies restrict its large-scale application. In this paper,the fixed and mobile liquid hydrogen storage equipment worldwide in recent years have been investigated. Aiming at the current technical challenges,the critical technologies of liquid hydrogen storage and transportation are summarized in terms of hydrogen storage materials,low-temperature insulation,fluid thermodynamic features,supporting equipment and standard system,etc. The current situation and the development trend of liquid hydrogen storage and transportation are analyzed. And the major development direction of liquid hydrogen storage and transportation technology in the future is proposed,which will effectively promote the research and development of high-performance liquid hydrogen storage and transportation equipment in China and ensure the safe use of liquid hydrogen on a large scale in the future.
