Organic Chemical Hydride (OCH) Method is a suitable for large scale H_2 storage and transportation. H_2 fixed to toluene chemically by hydrogenation reaction and toluene is converted to Methylcyclohexane (MCH). MCH has been easily stored and transported commercially, because it is in a liquid state under ambient temperature and pressure. H_2 is generated at a use-point by dehydrogenation reaction and toluene is recovered for recycle use as H_2 carrier. We had been proposed H_2 supply chain by using H_2 storage and transportation system by OCH method. H_2 production from fossil fuel with pre-combustion carbon treatment is an effective way for a clean utilization of fossil fuel. Since H_2 is also able to be produced from renewable energy, the establishment of this system can be contribute to solve the both of CO_2 emission and energy security issues of Japan.
