For liquid organic hydrogen carrier (LOHC) technology to be competitive with other H2‐storage methods, it is crucial to reduce the cost of LOHC materials occupying the high proportion of the embodied energy required for system implementation. Promising approaches are to convert crude or waste feedstock into LOHC materials and to utilize crude hydrogen sources obtained from various routes. Thus, in this review, the state‐of‐the‐art advances in sustainable LOHC‐based hydrogen storage using crude or waste feedstock, associated with their conversion into LOHC materials, and coupling crude hydrogen with LOHC system to obtain high‐purity H2 without separation and purification are highlighted. Petroleum sources like light cycle oil and pyrolysis fuel oil are used after liquid–liquid extraction, combined distillation/hydroprocessing, and one‐pot hydrotreating–hydrocracking. In case of converting renewable resources (e.g., biomass and plastic waste), depolymerization followed by hydrodeoxygenation is an effective approach. To utilize crude hydrogen sources for hydrogen storage, catalysts should be designed and synthesized toward activating LOHC hydrogenation reaction at lower temperatures, along with high CO resistance. Consequently, this context provides guidance for the development of LOHC technology to accelerate its commercialization.

The catalytic selective hydrodeoxygenation of guaiacol to value-added cyclohexane is one of the sustainable biomass utilization pathways for which the Ru/HZSM-5 support catalyst has been considered as promising. However, the effect of the catalyst morphology on the catalytic properties must be further investigated. Four Ru catalysts with different support morphologies, two-dimensional nanosheets (Ru/HZSM-5-P), brick-shaped (Ru/ HZSM-5-G), cross-shaped (Ru/HZSM-5-J), and irregular particles (Ru/HZSM-5-D), were prepared by the impregnation method to investigate the effects of catalyst morphology and acidity on the conversion efficiency of lignin-derived guaiacol to cyclohexane. The catalytic activity data showed that Ru/HZSM-5-P exhibited the best catalytic performance among the four catalysts with a conversion rate of 99.9% for guaiacol and a yield of 99.9% for cyclohexane. The characterization results showed significant differences among the four catalysts in terms of accessibility (thickness and pore volume), acidity, metal particle size, and reduction temperature. The Ru/HZSM-5-P catalyst with a two-dimensional nanosheet structure showed the best accessibility, smaller metal particle size, reasonable metal−support interaction, and appropriate B/L. The relatively strong acid centers facilitate the activation of C−C and C−O bonds. Besides, the reduced Ru species on the Ru/ZSM-5 catalyst exhibited high H 2 adsorption activity, which was beneficial for the adsorption of guaiacol. This indicates that the difference in catalyst morphology could greatly affect its catalytic activity, thereby altering the conversion rate of reactants and selectivity of the products.
