Liquid organic hydrogen carriers (LOHC) are organic compounds that can absorb and release hydrogen through chemical reactions. LOHCs can therefore be used as storage media for hydrogen. In principle, every unsaturated compound (organic molecules with C-C double or triple bonds) can take up hydrogen. To absorb hydrogen, the dehydrated form of LOHC (an unsaturated, mostly aromatic compound) reacts with the hydrogen in a reaction. The hydrogenation is an Toluene / methylcyclohexaneAs early as the 1980s there were attempts with, which is converted to by hydrogenation. The basic idea of this variant came from the USA in 1975 and was further developed in 1979 at the An alternative, innovative and highly promising approach to convert LOHC-bound hydrogen into electricity is proposed recently.
