To address the increasing global energy and environmental issues, safe and sustainable energy carriers alternative to carbon based fuels for the current power generation are being continuously explored. Hydrogen has long been attracted significant attention as a highly capable energy carrier because of its high energy storage density. Owing to its low volumetric energy density, however, a safe and economically viable hydrogen storage method that can transport large quantities of hydrogen still remains challenge. Cyclic and aromatic compounds possessing C=C bonds are potential hydrogen storage media that can store hydrogen as liquid forms with high volumetric H<sub>2</sub> storage capacities. Moreover, the hydrogen atoms stored can also be released as H<sub>2</sub> gas on demand in the presence of a proper catalyst. Here, we present novel eutectic mixtures of biphenyl and diphenylmethane and their H2-release properties. In addition, relevant hydrogenation and dehydrogenation reactors for different stationary fuel cell applications will be presented.
