Summary: The combination of hydrogen release from a LOHC system with EHC provides three advantages: reducing hydrogen pressure for accelerated release, compressing released hydrogen for high value, and purifying hydrogen by proton transport. This technology is suitable for producing compressed hydrogen for fuel cell vehicles at future hydrogen filling stations using LOHC.

Summary: The kinetics of dehydrogenation reactions of polycyclic naphthenes were simulated based on real experimental data. It was found that the reaction of the 1st order predominates in the series of cyclohexane-bicyclohexyl-perhydroparatherphenyl. However, for other substrates, the probability of describing the reaction using the 2nd order equation increases significantly, with the trans-decalin reaction becoming the predominant form of describing the kinetics.

Summary: This study investigates the reversible hydrogenation and dehydrogenation processes in a liquid organic hydrogen carrier (LOHC) system using a single-catalyst approach. Key hydrogen-involved catalytic behaviors, such as adsorption and migration, play crucial roles in reactivity. The findings demonstrate that employing a defective metal oxide support can facilitate these behaviors at the active sites on the catalyst surface during the LOHC process.

Summary: Liquid organic hydrogen carrier (LOHC) technology enables safe and convenient storage and transportation of hydrogen in large quantities. This study proposes a promising LOHC candidate, 1-(n-phenylethyl)naphthalene (PEN), which exhibits high hydrogen storage capacity, superior physical properties, and low cost. PEN showed reversible hydrogen storage and release performance, and the dehydrogenation performance can be enhanced by controlling the composition of stereo isomers.
