Chemical hydrides: A solution to high capacity hydrogen storage and supply

Cycloalkanes are good candidate media for hydrogen storage (6.5 wt% and 60 – 62 kg H 2 / m 3 ). A novel approach for the supply of hydrogen, through liquid organic hydrides (LOH) using catalytic reaction pair of dehydrogenation of cycloalkanes and hydrogenation of corresponding aromatics is a useful process for supply of hydrogen. Hydrogenation of aromatics is relatively well-established process. However, the efforts are needed to develop efficient catalyst for dehydrogenation of cycloalkanes. In this paper we review the dehydrogenation of cycloalkanes as useful reaction for storage of hydrogen in chemical hydrides.
