Clean and sustainable energy sources alternative to the current fossil fuels have attracted increasing attention to address the global warming issues likely caused by greenhouse gases. Hydrogen has been recognized as a clean energy carrier. The efficiency of hydrogen economy can be maximized in conjunction with fuel cell technologies. In order to achieve hydrogen economy, however, a safe and efficient hydrogen storage method is required. In this context, different hydrogen storage methods such as compression, liquefaction, and material based storage technologies have been proposed. Among those methods, liquid organic hydrogen carriers (LOHCs), particularly having aromatic/heteroaromatic structures, have intensively studied owing to their high volumetric hydrogen storage densities as well as safe, easy, and economical storage and delivery. We present here a eutectic mixture of biphenyl and diphenylmethane as a promising candidate material for hydrogen storage. The eutectic mixture proved its capability to store mass quantities of hydrogen as a chemical form in the presence of a Ru catalyst. Furthermore, the chemical and physical properties of the as-developed LOHC will be discussed.
