The large scale application of hydrogen-powered heavy-duty trains will help reduce fossil fuel consumption and reduce carbon dioxide emission.While the on-board hydrogen storage capacity usually exceeds 50 kg,the influence of hydrogen refueling station configuration on refueling performance is studied.The high-precision simulation to hydrogen refueling station is realized by using the dynamic process modeling,and the influence of the refueling performance is studied.Results show that the fueling capacity decreases significantly when the pressure of the tube trailer is low.The fueling performance of hydrogen refueling station can be improved through increasing the compressor capacity and the hydrogen storage bank in the station.Four kinds of hydrogen refueling station configurations are compared and studied.It is shown that the fueling capacity of the hydrogen refueling station with compressor capacity of 500 m3·h-1 and hydrogen storage bank size of 5 m3 is comparable with that of the hydrogen refueling station with compressor capacity of 1 000 Nm3·h-1 and hydrogen storage bank size of 3 m3,both can fill up the heavy-duty trains with hydrogen storage capacity of 150 kg and 65 kg in 50 minutes and 20 minutes,respectively.
