Sustainable and clean energy carriers alternative to fossil fuels are being explored to mitigate the increasing energy and environmental issues. Hydrogen is considered as a viable renewable energy carrier owing to its high gravimetric energy storage density of ca. 33.3 kWh·kg-1. However, the low volumetric energy density of gaseous hydrogen limited its use for numerous energy applications particularly associated with high capacity and long distance hydrogen transportation. In the context, a safe hydrogen storage system capable of transporting large quantities of hydrogen in a liquid form has attracted particular attention. In the presentation, numerous liquid organic hydrogen carriers(LOHC) applicable to different fuel cell applications are introduced and their hydrogenation and dehydrogenation properties will be discussed.
