英文要約Title: Technology Development for the Realization of the Hydrogen society. Technology Development of Systems using Renewable Energy-derived Hydrogen. Development of Hydrogen Production-storage-utilization System adopting Hydrogen Production Device with the Electric Generation Function (FY2014-FY2015)FY2014 Annual Report

1. Examinations of the suitable introduction sites for the hydrogen production-storage-utilization system and clarification of the system merits
The hydrogen production-storage-utilization system mainly consists of the water electrolizer-fuel cell unitized reversible cell (URC) system and the hydrogen storage tank system. In this financial year, the qualitative features and functions of the system were identified for examining the suitable introduction sites of the system in the next financial year.
The features of the system were identified as features of the URC system and the metal hydride alloy tank system, which is one of the hydrogen storage tank systems. The functions of the system were identified by the evaluation index such as energy supply, environmental and practical use.

2. Comparative verification for the hydrogen storage methods
The hydrogen storage tank in the AIST uses 50 kg of MmNi5 metal hydride alloy. The volume of the storage tank is 0.018 m3. The utilizable hydrogen capacity is about 5.5 Nm3. The maximum operating pressure is less than 1.0 MPa. The total volume of the metal hydride tanks in the Savannah River National Laboratory is about 0.049 m3 and the utilizable hydrogen storage capacity is about 18 Nm3. The maximum operating pressure is 1.48 MPa. The Toshiba Corporation will be testing the self-contained energy supplying system with hydrogen, “H2One”. This system has two medium pressure hydrogen tanks with the volume of 17 m3 each. The apparatuses of the system are installed in three 20 feet containers. The maximum operating pressure is 0.8 MPa and the total utilizable hydrogen capacity is 275 Nm3. If the two medium pressure hydrogen tanks are replaced to the metal hydride tank of AIST, the 46 of metal hydride tanks will be needed. However, the total tank volume will be 1/40 for the medium pressure hydrogen tanks. Toshiba also has a plan of the 5 MW hydrogen electric power storage system. A medium pressure spherical hydrogen tank with the volume of 1600 m3 will be prepared for the system. The utilizable hydrogen storage capacity is 15200 Nm3 with the maximum pressure of 0.95 MPa. The same kind of hydrogen system has been operated in the Corsica in France. The project is called “MYRTE”. The hydrogen system is 0.5 MW-class. 1400 Nm3 of hydrogen is stored in the high pressure hydrogen storage tank with the maximum pressure of 3.5 MPa. The hydrogen tank volume is estimated at about 39 m
3. The hydrogen storage capacity for the field test in this project is 18 Nm3. On the other hand, the hydrogen storage capacity of the hydrogen system for the business plan will be about 1200~1800 Nm3. In the next financial year, we will investigate the best hydrogen storage methods for each system by considering the conditions of the system size and the installation site.
