N2 - The world's increasing greenhouse gas emissions and the rapid consumption of fossil fuels have led researchers to develop safe and efficient energy sources. Hydrogen, which can be produced from renewable sources, is a clean and sustainable solution to the energy crisis. However, a reliable storage method is essential to meet the demands of the hydrogen economy. In recent years, liquid organic hydrogen carriers (LOHC) systems have gained considerable importance for demonstrating a compelling storage solution for hydrogen produced through water electrolysis using renewable electricity sources. LOHC technology is composed of cyclic hydrogenation and dehydrogenation of organic H2-lean and H2-rich compounds of LOHC systems, respectively. Implementing this new technology requires achieving an effective release of hydrogen from the organic molecules, primarily significant thermal heating is required for the endothermic dehydrogenation reaction of LOHC. Hence, employing a highly active, selective, and reusable catalyst is crucial to mitigate the dehydrogenation temperature while increasing the amount of liberated hydrogen and suppressing the formation of side reaction products. As catalyst development is a vital aspect of LOHC technology, the recently commenced work is currently investigating the preparation and assessment of heterogeneous catalysts for both hydrogenation and dehydrogenation in LOHC systems.
