The organic chemical hydride (OCH) method for the hydrogen storage and transportation has both of the high gravimetric and volumetric hydrogen density. This method has low potential risk, because hydrogen is stored as the chemical liquid under the ambient pressure at the room temperature. However, this method has not been established technically, because dehydrogenation catalyst did not have been attained the enough stability and the sufficient performance. Chiyoda Corporation has developed the dehydrogenation catalyst for a fixed bed reactor with the high stability and the sufficient performance. This catalyst can generate hydrogen from methylcyclohexane (MCH :99.9%) with conversion: ＞95%, toluene selectivity: ＞99.9%, hydrogen generation rate: ＞1000 Nm3/h/ m3-cat under the reasonable condition of 593K (320℃), ambient pressure, LHSV:2.0h-1 and co-feed hydrogen:5～20mol% in feed. The hydrogen energy chain as a future global vision by OCH method is also proposed.
