英文要約Title:Development of Technologies for Hydrogen Production, Delivery, and Storage Systems. Research and Development of Elemental Technologies for Hydrogen Station Components. Research and Development of Compact Hydrogen Station for Urban Areas Use (FY2008-FY2012) FY2010 Annual Report

The laws and regulations concerning compact hydrogen stations were studied to clarify any restrictions on the legal distance governing fixed manufacturing facilities and specified hydrogen compression stations. Also clarified were the subject items of which revision would produce positive effects to facilitate the introduction of compact hydrogen stations out of 16 subject items of the ongoing review by the Regulations and Systems Subcommittee of the Government Revitalization Unit. The merits and demerits of the installation of a pressure accumulator, compressor and other equipment on a canopy or underground were examined along with the examination of possible measures to ensure safety in both the horizontal and vertical directions. This led to examination of a concrete concept for a compact hydrogen station, the construction of which should be feasible not only from the viewpoint of the legality but also from the viewpoint of the structure, including beams, doors and other components. In numerical study, to reduce the blast pressure released to outside air from the basement room by the explosion accident, we investigated the effective air vent shape by using numerical parameter studies. As a result, it was found that the pressure reduction plate with a hole installed inside the air vent could reduce the blast pressure discharged into outside. We confirmed that the pressure reduction effect was changed by the number of the plates, the opening size and the interval. And the most effective shape of the air bent was shown. In verification experiment, we carried out the verification experiments to examine the blast pressure reduction effect of the plate inside the air vent and to verify the accuracy of the numerical simulation. We confirmed the pressure reduction effect of the plate and the high prediction accuracy of our numerical simulation. In development of hydrogen combustion control system, a mixture of hydrogen with air and helium was ignited during a very fine water spray (particle diameter is 16 microns and water rate is 50 mL/min per 1 nozzle) in a combustion container (500mm width x 170mm height x 500mm length). The hydrogen mixture combustion was prevented when 8 water spray nozzle and 24% helium were used for 8% hydrogen concentration. In case of increased 16% hydrogen concentration, 8 water spray nozzles and 24% helium are required to prevent the combustion. Inner frame was needed to make the quenching effect of water spray. The pressure often becomes larger when the water spray was applied. It means that some apparatus to make the air turbulence smaller is to be developed. Construction cost estimation of each type of compact hydrogen station was performed. As a result, the underground type is a half times as low as the base model considering land rent in urban area.
