Ceramic Porous Absorber for Hydrogen Storage

Abstract

The study is devoted to the processes of hydrogen absorption in porous ceramic materials and the study of the main approaches to solving the problem of hydrogen storage. Various modern methods for storing hydrogen in various states of aggregation are described, including storage in a liquefied form at low temperatures and in chemically bound forms such as metal hydrides. The results include the synthesis of porous materials for hydrogen absorbers, suggesting various types of hydrogen absorbers in the form of porous materials. The study shows the dependence of the degree of hydrogen absorption on the composition of the absorber and the temperature of hydrogen sorption. A ceramic porous material with a zeolite composition of sodium aluminosilicate (AlSiNaO) has been developed, exhibiting a high hydrogen absorption coefficient (13.2 wt.%).
