LOHCs provide a flexible media for the storage and transportation of high-purity hydrogen, without losses even for long distances, using the existing fuel infrastructure. They have a higher gravimetric as well as a higher volumetric energy density as compared to other fuels used for commercial applications. Hydrogen is stored in these liquid-phase organic compounds for transportation, and is extracted on-demand. LOHCs retain their core molecular structure after both catalytic reactions, hydrogenation and dehydrogenation, thus eliminating the need for a new energy carrier after every cycle. While the hydrogenation reaction is exothermic in most cases, the dehydrogenation reaction is endothermic, which allows for coupling of these reactions within a reactor in order to maximize efficiency.
