[0002] The ocean water body has a huge reserve and contains nearly unlimited hydrogen resources, so the hydrogen production technology by electrolysis of seawater is becoming an important direction of the green hydrogen strategy. However, the large-scale, long-period storage and safe transportation of hydrogen obtained by seawater electrolysis are still key bottlenecks. The organic liquid hydrogen storage (LOHC) technology is widely adopted due to the advantages of high hydrogen storage density, liquid delivery at normal temperature and pressure and recyclable use. The technology uses hydrogen storage solvents containing unsaturated carbon-carbon bonds such as olefins, alkynes or aromatic hydrocarbons, and realizes the 'chemical fixation' and 'controllable release' of hydrogen through reversible hydrogenation / dehydrogenation reactions. In a typical hydrogen-electricity combined supply system, the hydrogen storage solvent is usually called 'hydrogen oil', and the dehydrogenated solvent is called 'dehydrogenated hydrogen oil'.
