Chemically pure hydrogen is essential for use in fuel cells to generate electricity. Hydrogen produced from renewable raw materials biotechnologically contains a lot of impurities which deactivate the fuel cell batteries. Therefore, the effective development of hydrogen energy is need hydrogen accumulation systems, safe storage and preparation of chemically-pure hydrogen. Hydrogenation of benzene was carried out in a laboratory high pressure autoclave PARR-300 by stirring the reaction mass at a temperature of 180oC and pressure 70 atm and naphtalene at 280oC and 90 atm. We have used hydrogen produced from renewable raw material to hydrogenation of benzene and naphtalene. Dehydrogenation of cyclohexane and decalin [1] prepared by hydrogenation was carried out at temperatures 260–340°C and flow rates 1 h-1 in a flow reactor. The activities of various catalysts based Pt, Pd and Ni in reversible reactions of hydrogenation-dehydrogenation of aromatic compounds have been compared in order to produced chemically pure hydrogen from hydrogen-containing mixture. Hydrogen purity from dehydrogenation reactions was checked by chromatography. As a result, the possibility of selective accumulation and generation of chemically pure hydrogen instead of hydrogen from renewable raw material is shown [2]. [1 A. Kalenchuk, D. Smetneva, V.
