Topic: Organic hydride for hydrogen energy carrier

Abstract

Hydrogen storage and transportation are critically important to realize a low-carbon society. A hydrogen supply chain concept has recently been proposed by Chiyoda Corporation on the successful basis of catalytic methylcyclohexane dehydrogenation, coupled with well-established toluene hydrogenation and existing delivery infrastructures at low cost. The SPERA Hydrogen” process ensures liquid storage of hydrogen energy for safe large-scale and long-distance transportation (even abroad) under ambient temperature and atmospheric pressure. Overall costs would generate business risks. High-equilibrium temperatures and large enthalpy change (H) are deficit in this reversible reaction couple. Utilization of various types of exhaust heat and development of a compact-size dehydrogenation reactor should be explored.
