財団法人石油産業活性化センター(以下PEC)、株式会社日本製鋼所、株式会社キッツ、財団法人金属系材料研究開発センター(以下JRCM)、株式会社山武の5者は連名により、PECを代表委託先として平成20年度より、70MPa級水素ステーションの低コスト化に向けた取組を開始している。平成21年度の事業では、平成20年度のFSに基づき立案したコスト低減の要素技術開発に取組むとともに、他NEDO事業等と連携して、将来的なコスト低減見通しとコスト構造の推定を行っている。
1. ステーション全体のコスト低減策候補の提案と総合的エンジニアリング技術の開発(PEC)
1.1水素ステーションの設備、運用の最適化検討
連名委託先で開発中の高容量化蓄圧器と制御システムとを組合せ、コスト低減型ステーションを構築するため、最適化検討を行った。ダイナミックシミュレーションによる充填時間の検証を行い、300Nm3/h(5台/h)の充填が可能な差圧充填型最適モデルを検討した。
1.2スキッド化による工事費用の低減
水素ステーションのプロットプランや機器荷重に対する基礎の設計施工仕様を調査、分析し、またステーション付属品、電気設備等に関する情報収集を行った。これらの結果をもとに、スキッド化の対象とする範囲を定め、具体的な検討に着手した。

Experimental study for low-cost station components has started in 2009, based on 2008 techno-commercial study in which technically key issues for obtaining a low-cost 70MPa hydrogen station were extracted. Future estimation of station cost and the structure was obtained.
1. Station modeling, cost estimation, and optimization study (JPEC)
The optimized differential pressure station model was studied using dynamic simulation, in which 300Nm3/h(5cars/h) of refueling is possible. Based on the station plot plan and associated study, skid mount station study has started
2. 70MPa Class Large Capacity Hydrogen Storage Tanks (JSW)
Tempering characteristics of two heats of SA723 steel were evaluated, and notched tensile tests in 45MPa gaseous hydrogen were conducted. The notched tensile stress turned to decrease around the tensile strength of 930MPa. A fatigue testing machine was introduced and the test material, which will be utilized for autofrettage cylinder, was prepared by vacuum induction melting. Detection test for hydrogen crack propagation by Acoustic Emission(AE) method has shown the possibility.
3. High Pressure Hydrogen Valves (KITZ)
Material selection and FEM analysis of ball seats and packing was conducted for good durability performance of a ball valve, which can be designed compact and low-cost. Through a partial designing and prototyping, the most suitable design of ball seats and packings was determined in addition to compact design for actuation. Primary design of ball valves (automated shutoff valve and manual valve) was completed.
4.High-strength and low-cost materials (JRCM)
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 were produced and served to manufacturers, and the obtained data such as SSRT testing was provided to further evaluation.
5. Station control system and control valve (YAMATAKE)
Defined control system structure that enables control panel footprint and cost as planned. Also, defined specifications of control software for JPEC standard station model including utilization of multiple compressors, hydrogen storage tanks, and dispensers for future practice. Developed the surface treatment method for valve stem to keep sealing performance up to 300,000 cycles under hydrogen atmosphere.
