A hybrid dehydrogenation reaction system includes: an acid aqueous solution tank having an acid aqueous solution; an exothermic dehydrogenation reactor including a chemical hydride of a solid state and receiving the acid aqueous solution from the acid aqueous solution tank for an exothermic dehydrogenation reaction of the chemical hydride and the acid aqueous solution to generate hydrogen; an LOHC tank including a liquid organic hydrogen carrier (LOHC); and an endothermic dehydrogenation reactor receiving the liquid organic hydrogen carrier from the LOHC tank and generating hydrogen through an endothermic dehydrogenation reaction of the liquid organic hydrogen carrier by using heat generated from the exothermic dehydrogenation reactor.

A system for distribution of hydrogen gas in a metal hydride reactor is disclosed. The system comprises a hydrogen distribution conduit positioned within a metal tube so as to define an annular space between the hydrogen distribution conduit and the outer metal tube. The hydrogen distribution conduit provides a flow passage for the hydrogen gas. A metal sponge matrix containing hydrogen-storing metal powder or hydrogen-storing alloy powder is filled in the annular space. The system provides a more uniform distribution of hydrogen across the particles of the hydrogen-storing metal/alloy powder, provides mechanical support to the hydrogen distribution conduit, improves the thermal conductivity of the powdered metal/alloy bed and reduces the size and production cost of the reactor.
