英文要約Title:“Research and Development for Hydrogen Production, Transportation and Storage System / Research and Development for Elemental Technology of Hydrogen Refueling Station Components / Research and Development for Low-cost 70MPa Hydrogen Refueling Station”(FY2008-FY2008)FY2008 Annual Report

A techno-commercial study for cost effective components was conducted on 70MPa Hydrogen station. Current components were classified and studied on each element basis, in order to extract technically key issues for obtaining a low-cost 70MPa hydrogen station.
1. 70MPa Hydrogen Station modeling and cost estimation
70MPa Hydrogen station base model was studied, and it was estimated that the construction cost of the base model is 660 million yen, and 435 million yen for a low-cost model. However, as for station specifications, the capacity of the accumulator or the compressor should be determined through an optimization study. Cost reduction through total engineering of station, associated with optimization study for those specifications is planned in 2009 and 2010.
2. 70MPa Class Large Capacity Hydrogen Storage Tanks
Candidate materials are studied and it was concluded that ASME SA723 steel is the best due to its excellent hardenability. A cost analysis showed 50 percent of the production cost could be cut by enlargement of tank capacity. Two construction techniques, “autofrettage” and “shrinkage fitting” are evaluated and a sound monitoring method consists of acoustic emission(AE) and ultrasonic inspection(UT).
3. High Pressure Hydrogen Valves
Reducing refueling time to FCV is the most critical issue for current 70 MPa Hydrogen refueling station. A ball valve, which can be designed compact and have better flow efficiency, seems to be the most economical solution. The technical subjects, sealing performance of ball seats, durability, and technology for more compact design for actuation will be studied.
4.High-strength and low-cost materials
Effective methodology for strengthening and suppress of high-cost-nickel use for cost reduction of austenitic stainless steels are focused to obtain new materials. For the achievements of the target, we shall take 1) solution precipitation and work hardening approaches for the material strengthening and 2) alternative raw elements selection such as manganese. Lab-scaled materials will be produced and served to manufacturers, and the obtained data will be provided to future standardization.
5. Station control system and control valve
Control equipments and devices are currently supplied by each supplier’s scope, so it seems to be essential to optimize them. A control scheme with a unified system from compressor to dispenser will be the desirable structure. The system model will be designed and implemented. Control valve sealing-related parts must be investigated and developed to achieve higher reliability, and a cost reduction effort will follow using a new material.
