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.

経済産業省が水素燃料電池戦略ロードマップを2016年3月に改訂するなど、エネルギー媒体としての水素利用はますます注目されている。経営情報部会WG1では、水素利用の進展が日本のエネルギー業界に与える機会や脅威をシナリオプランニングの手法を用いて検討した。本検討では、地方自治体の特性でシナリオを書き分けており、本講演では、人口密度の高い都市のシナリオについて、ドライバーや帰結を報告する。

Mid- and long- term energy balances of Japan were investigated after the Great East Japan Earthquake on the 11th of March, considering fossil fuel imports, environmental constraints, and economy as well as risks revealed by Fukushima nuclear accidents and disasters. It is concluded that i) great uncertainties on technology and economy are apprehensive about renewable energy oriented energy balance, ii) nuclear power is still an indispensable technological option, and iii) fossil fuels are necessary to meet the balance without both renewables as well as nuclear. The "energy best mix" strategy, which had long been the core philosophy in the Japanese energy policy, should not be amended with the severe nuclear accidents after the Earthquake.
