英文要約Title: Hydrogen Utilization Technology Development/ Research and Development on Improvement of Domestic Regulations, International Standardization and Harmonization for Fuel Cell Vehicles and Hydrogen Infrastructure/ Research and Development on the Expansion of Utilizable Steel Grades for Hydrogen Refueling Station (FY2013-FY2017) FY2013 Annual Report

1.Research and development toword the utilization of lower-cost and/or higher-strength materials
1)Planning and preparation (JPEC)
To manifest the operating pressure and temperature of mechanical components in the actual use of hydrogen fueling station, practical issues and related requests from industries were summarized. Accordingly, further research and development were planned and prepared for the following materials:
-Copper and brass: Low cost materials for low pressure hydrogen
-Low alloy steel SCM435: Low cost material for high pressure hydrogen
2)Review for the newly proposed design concepts to utilize lower cost materials in high pressure hydrogen (KHK, Kyushu Univ., JPEC)
In view of the utilization of lower cost materials, a series of strength properties (i.e. ductility, fatigue life and fatigue crack growth) in high-pressure hydrogen were investigated with respect to low alloy steel SCM435 and carbon steel SM490B. Based on the results, novel concepts of design-by-rule and design-by-analysis were proposed by HYDROGENIUS, and then they were discussed in Joint Meeting. Further promotion of the research and development on SCM435 was agreed in Sub-committee on Material Regulation, and additional experiments for next year were prepared with the efforts of JPEC.
3)Proposal for the revision of Technical Standard of KHK (JPEC)
A revision of the Technical Standard was proposed to enable copper and brass to be utilized under low pressure hydrogen. The proposal was approved in Steering Committee and Sub-committee on Material Regulation.
2.Development of database for the utilization of materials in higher pressure hydrogen over a wider range of temperature
1)Planning and preparation (JPEC)
Based on surveys on the operating pressure and temperature of mechanical components in the actual use of hydrogen fueling station, further research and development were planned and prepared for the following materials:
-SUS316 (High Ni equivalent): Moderate strength austenitic stainless steel
-SUH660: Iron-base alloy used for pipe, mechanical joint and nozzle
-XM-19 (HRX19): Weldable high strength austenitic stainless steel
2)Evaluation tests and reviewing the results (KHK, Kyushu Univ., JPEC)
To clarify the availability of austenitic stainless steel SUS316 (High Ni equivalent) and iron-base alloy SUH660 in low-temperature hydrogen atmospheres (e.g. pre-cooler in hydrogen station), slow strain rate tests (SSRTs) were carried out at pressure and temperature of 106 MPa and -45 °C in HYDROGENIUS. The experimental results clarified that both the steels can maintain a sufficient ductility even in the low temperature hydrogen. Accordingly, the applicability of the experimental data was approved in Steering Committee and Sub-committee on Material Regulation.
Moreover, the excellent resistance against hydrogen of high-strength austenitic stainless steel XM-19 was found in a series of experiments in HYDROGENIUS. Further investigations to confirm the availability of XM-19 was agreed in Steering Committee and Sub-committee on Material Regulation.
3)Proposal for the revision of Technical Standard of KHK (JPEC)
A revision of the Technical Standard was proposed to enable SUS316 (High Ni equivalent) to be used over a wider range of temperature. The proposal was approved in Steering Committee and Sub-committee on Material Regulation.
