Development Status and Prospects of Liquid Hydrogen Refueling Station and Its Key Equipment

Abstract:

Hydrogen energy is recognized as one of the most potential energy sources in the 21st century due to its non-polluting， high calorific value， and wide sources. As one of the forms of hydrogen energy utilization， hydrogen refueling stations are divided into gas-hydrogen refueling stations and liquid hydrogen refueling stations. Compared with gaseous hydrogen， liquid hydrogen may become the main form of utilization in the future due to its high density and high storage and transportation efficiency. In this paper， the process flow of liquid hydrogen refueling station is given. Then， the compression， gasification， storage， transportation， refueling process， equipment and risk research of hydrogen refueling station， are introduced respectively. Finally， the future of liquid hydrogen refueling in China is prospected， providing reference for the large-scale application of liquid hydrogen refueling stations.
