“…Early LOHC studies focused on polycyclic hydrocarbons due to their several advantages, such as their high gravimetric hydrogen contents (5 wt%-8 wt%), high volumetric hydrogen storage capacities (>60 g H 2 /L), and reversibility between hydrogenation and dehydrogenation. Simple aromatic compounds such as benzene [53,54] and toluene [55,56] were intensively investigated in the 1980s as early LOHCs, but these LOHCs will not be addressed in this review.…”

Here, we review liquid organic hydrogen carriers (LOHCs) as a potential solution to the global warming problem due to the increased use of fossil fuels. Recently, hydrogen molecules have attracted attention as a sustainable energy carrier from renewable energy-rich regions to energy-deficient regions. The LOHC system is one a particularly promising hydrogen storage system in the “hydrogen economy”, and efficient hydrogen mass production that generates only benign byproducts can be applied in the industry. Therefore, this article presents hydrogenation and dehydrogenation, using homogeneous or heterogeneous catalysts, for several types of LOHCs, including formic acid/formaldehyde/ammonia, homocyclic compounds, nitrogen- and oxygen-containing compounds. In addition, it introduces LOHC system reactor types.

“…A number of research groups have investigated the CBH cycle. ,,− Cacciola et al reported that the reaction reversibility and selectivity in the CBH cycle is higher than that of MTH and DNH cycles. Kariya et al , studied hydrogen production from cyclohexane, MCH, and decalin and reported that the highest production rate was obtained from the dehydrogenation of cyclohexane.…”

Hydrogen Storage in Liquid Organic Hydride: Producing Hydrogen Catalytically from Methylcyclohexane

Hydrogen storage for stationary and mobile applications is an expanding research topic. One of the more promising hydrogen storage techniques relies on the reversibility and high selectivity of liquid organic hydrides, in particular, methylcyclohexane (MCH). The use of liquid organic hydrides in hydrogen storage also provides high gravimetric and volumetric hydrogen density, low potential risk, and low capital investment because it is largely compatible with the current transport infrastructure. Despite its technical, economical, and environmental advantages, the concept of hydrogen storage in liquid organic carriers has not been commercially established because of technical limitations related to the amount of energy required to extract the hydrogen from liquid organic hydride and the insufficient stability of the dehydrogenation catalyst. This paper provides a review for the effort that has been directed toward the development of this concept over the past few decades and mainly focuses on the catalytic production of hydrogen from MCH. The topics that have been covered are the kinetics of MCH dehydrogenation over Pt/Al2O3 and Pt–Re/Al2O3 catalysts, the kinetics of catalyst deactivation, the thermodynamic equilibrium in MCH dehydrogenation, and the sulfur impact on the MCH dehydrogenation reaction.

“…In the field of hydrogen storage, cycloalkanes have attracted some attention in the past two decades under the name ''liquid organic hydrides'' (LOH), [123][124][125][126][127] which refers to solid hydrides such as NaBH 4 , LiBH 4 etc. The hydrogen content of cycloalkanes is comprised of between 3 wt% for tetralin and 7.1 wt% for cyclohexane.…”
