Most of the completed hydrogen storage and transportation stations in China are high pressure hydrogen storage and transportation stations. The efficiency of high pressure hydrogen storage and transportation is low, the economic hydrogen supply radius is small, the single hydrogen supply scale is small, and the core equipment of high pressure hydrogen storage and hydrogenation stations-hydrogen diaphragm compressor has high value, high energy consumption and short service life. In order to solve the above problems, the construction of combined stations for liquid hydrogen vaporization and hydrogenation is put forward, in order to make full use of more than 2000 stations already built in China. The technical solution realizes the functions of gas hydrogen hydrogenation of fuel cell vehicle, filling of hydrogen long tube trailer, liquid hydrogen filling of liquid hydrogen fuel cell vehicle, gas filling of compressed natural gas (CNG) vehicle and filling of CNG long tube trailer in a joint construction station. It can achieve 3 times of hydrogenation scale on the same floor area of high-pressure hydrogen storage and hydrogenation stations, increase the type of energy filling in the co-built stations, reduce the investment cost of the co-built stations, and improve the operation economy of the co-built stations.
