英文要約Title: Research and Development of Technology for Hydrogen Utilization. Research and Development on Improvement of Domestic Regulations, International Standardization and Harmonization for Fuel Cell Vehicles and Hydrogen Infrastructure. Research and Development on Regulation review for Construction, Operations, etc. of a Hydrogen Refueling Stations. (FY2013-FY2017) FY2015 Annual

(1)Safety inspection standard for 70MPa Hydrogen Refueling Stations(HRSs)
The following items have been carried out this year to draft a reasonable safety inspection standard for 70MPa HRSs and a safety technical standard for HRSs.
1) Evaluation of safety inspection standards for HRSs.
2) Evaluation of regular voluntary inspection.
3) Study for standardization of Ultrasonic Testing (UT) method for accumulator.
4) Evaluation of safety technical standards for HRSs.

(2)The pressure relief devices(PRD) for composite vessel installed in hydrogen trailer
The following items have been carried out this year to draft a technical standard in High Pressure Gas Safety Act (HPGSA) in order to use thermally actuated safety valves (glass bulb type) that are practically in use overseas for hydrogen trailers.
1) Follow-up study for the regulatory review process of proposed draft

(3) Revision of safety distances for HRSs
The purpose of this study is to propose new safety distances for HRS required by HGSA through evidence based approach.
The following items have been carried out this year;
1) Study of hydrogen diffusing and ignition
The experiment for detail analyses of high pressure hydrogen gas diffusion which reflects a fluctuation of the concentration was made.
The data for detail analyses of high pressure hydrogen gas diffusion was collected.

(4)-1.Refueling H2 to FCVs on public roads
Finished.

(4)-2 Same as the above(Refueling H2 to FCVs at dealer)
Finished

(5) Mitigation of maximum temperature on hydrogen trailer containers
In order to prevent a recurrence of fire on hydrogen trailer, the following items have been carried this year.
1) Study of safety measures for prevention of fire on hydrogen trailer
2) Study of a safety technical guideline for hydrogen trailer

(6 ) Technical standard for HRSs with cryo pump
The following items have been carried out this year to draft technical standards in HPGSA for HRSs with cryo pump that will be prepared as the favorite model of LH2 storage type HRSs which has already been enforced.
1) Design of the experiment for data acquisition that was necessary for the risk assessment.
2) Study of related technology for HRSs with cryo pump.
3) Study of risk assessment and safety measures of HRSs with cryo pump.

(7) Technical standard for small hydrogen supply equipment
The following items have been carried out to draft a technical standard in the HPGSA, which enables small HRSs having less than 30 m3/day production capacity to be constructed in the urban area adjacent to a conventional gas station.
1) Study of safety measures for High differential pressure water electrolysis.
2) Follow-up study for the regulatory review process of proposed draft.

(9)Revision of sprinkling facilities standard
The following items have been carried out this year to propose new sprinkling facilities standard for HRS.
1) Investigation into law concerned and study of quantity of sprinkling reduction method
2) Study of estimation method of hydrogen accumulators temperature using simulation

(10) Technical standard for self-service refueling systems at hydrogen stations
The following items have been carried out this year to draft a technical standard for self-service refueling systems at HRSs.
1) Investigation into past study contents of quantity of self-service refueling systems
2) Study of the technical problem self-service refueling systems
