Hydrogen is expected to play an important role in the transportation sector for fuel cell vehicles (FCVs) . The infrastructure of hydrogen refueling stations from low cost sources like natural gas is necessary to the successful transition toward hydrogen-based society. Osaka Gas has successfully demonstrated the on-site hydrogen production system with low-pressure reformer at the first hydrogen refueling station based on steam methane reforming (SMR) in Japan under World Energy Network (WE-NET) Project. We also developed a new compact hydrogen production system with medium-pressure reformer for hydrogen infrastructure as well as industrial use. The basic unit generates 30Nm3⁄h pure hydrogen (99. 999%) , and all components are packaged on one skid. Our development effort realized to reduce 50% installation area, 50% capital cost and 30% operating cost compared with our conventional system.
The paper will describe our conventional on-site hydrogen production system based on SMR that was installed at the WE-NET hydrogen refueling station in Osaka, and subsequently focus on the detail of our new compact hydrogen production system for wide variety of applications.
