英文要約Title: Advancement of Hydrogen Technologies and Utilization Project/ Analysis and Development on Hydrogen as an Energy Carrier/ Economical Evaluation and Characteristic Analyses for Energy Carrier Systems (FY2014-FY2015) FY2014 Annual Report

(1)Economical Evaluation and Characteristic Analyses for Energy Carrier Systems
Based on the actual conditions about the energy supply and demand, and the visions for renewable energy utilization, requirements or constrains for the framework were derived. Defining the frameworks, where the systems from renewable energy electricity generating, converting to energy carriers, consuming at final demands, have economically advantages to the referring conventional systems, the economical evaluation and characteristics analyses were performed, comparing 3 systems containing proposed novel process.
(2)Cost Analysis of Energy Carrier Technologies
Interviews with researchers of liquefied hydrogen, ammonia, methylcyclohexane and methanol were performed for the purpose of collecting technical information related to estimating a maximum possible capacity, achievable unit efficiency, plant construction cost, etc. and this information was reflected into the assumption in cost calculation. The cost analysis framework, which is a common assumption for comparing each energy carrier, was developed by expanding the cost analysis guideline developed in FY2013. The scope of the analysis covers from the acceptance of hydrogen produced from low carbon resources, synthesis of energy carriers, its transportation and storage, international transportation, and then domestic delivery as necessary after unloading in Japan. An analysis of costs and efficiency of each energy carrier in 2030 was carried out.
(3)Impact Evaluation of Long Term Global Energy Supply and Demand
Global energy model GRAPE framework was expanded and tested to include up-to-date information of production, transportation and utilization of low CO2 energy carriers. New energy carrier flows were added to the prototype model. This flow contains use of imported energy carriers (liquefied hydrogen, ammonia and methyl-cyclohexane (MCH)) for transport, power generation and other demands in Japan. Results of the carrier cost analysis described in (2) were used in the analysis.
(4)Development of Scenario on Hydrogen Technologies and Utilization
To show technology development efforts to be made mainly for production, storage and transportation technologies and their direction, scenarios and challenges were derived in introducing the system to produce hydrogen through electrolysis using electricity generated from renewable energy and store, transport and utilize such hydrogen or converted energy carriers including ammonia, etc., in consideration of the analyses on efficiency and cost of specific elements and the entire system. Situations of introduction and dissemination on hydrogen energy in 2030 and 2050 were assumed to set the target amount of hydrogen introduced and establish time changes in supply cost and permissible cost of hydrogen, which can achieve the target amount of hydrogen introduced, by use of a scenario frame through back-casting.
