PROBLEMS OF ACCUMULATION AND STORAGE OF HYDROGEN

The attractiveness of hydrogen as a universal energy carrier is determined by the ecological purity, flexibility and efficiency of energy conversion processes with its participation. Technologies of a multiscale production of hydrogen are well developed and have an almost unlimited raw material base. However, the low density of gaseous hydrogen, the low temperature of its liquefaction, and also the high explosive danger combined with the negative impact on the properties of structural materials put the problems of developing economically and technically effective and safe hydrogen storage systems at the forefront. It is these problems that hinder the development of hydrogen energy and technology at the present time. The proposed review is devoted to modern hydrogen storage systems. Existing technologies of hydrogen storage are considered: physical and "chemical" methods.
