This paper presents a cost analysis on hydrogen energy carrier supply chains using three different hydrogen energy carriers, such as liquefied hydrogen, ammonia, and organic hydrides (Toluene and Methylcyclohexane). An international supply chain from a foreign country to Japan by ship is the target of this analysis. The authors calculated hydrogen supply cost per 1 normal cubic meter in 2030 and 2050. For 2030 case, the cost, capacity, and efficiency of each facilities, which includes technological advancement to 2030, are summed up. For 2050 case, cost, capacity, and efficiency of facilities are assumed in order to realize the targeted cost 20 JPY/Nm3. The authors set comparable conditions among the carriers, calculated material and energy balances, assumed facilities in three supply chains, and got CAPEX and OPEX of the supply chains. As a result, the authors got two findings. Firstly, among three supply chains, there is small supply cost difference in both 2030 and 2050. Secondly, by comparing the supply costs of each carrier in 2030 and that of 2050, the authors found essential points of research and development; liquefaction, storage and shipping for liquefied hydrogen, composition and decomposition for ammonia, and dehydrogenation for organic hydrides.
