Comparison of Hydrogen Transportation Methods for Hydrogen Refueling Station

This paper first presents a review of the existing hydrogen delivery methods.Then a study is made of the delivery cost,energy consumption and the safety of hydrogen transportation by tube trailer,tank and pipe.A hydrogen transportation cost model is established to calculate the large-scale hydrogen transportation cost in Shanghai.The results show gaseous hydrogen(GH2) transportation cost by tube trailer is 2.3 RMB·kg-1,liquid hydrogen(LH2) by tank is 0.4 RMB·kg-1,and GH2 by pipe is 6 RMB·kg-1.Regarding to the energy consumption,hydrogen liquefaction consumes more than 30% of its low heat value(LHV);about 3 times of hydrogen compression.There may exitst some risks such as.high-pressure,LH2 boil-off and permeability during the delivery,which can be avoided cylinder design,regulation and so on.Based on the analysis result,hydrogen delivered by tube trailer is the best option for a plan to establish a scale of about a thousand fuel cell vehicles in Shanghai.
