Method and system for releasing hydrogen gas from an at least partially loaded carrier material

Abstract

A method for releasing hydrogen gas from at least partially loaded carrier material includes the following method steps: in a first dehydrogenation reactor (2), dehydrogenating the carrier material from an initial degree of hydrogenation to a first degree of hydrogenation by contacting the carrier material with a catalyst material and thereby releasing hydrogen gas, wherein the carrier material leaves the first dehydrogenation reactor (2) with a liquid phase proportion of at least 5%, transferring the carrier material, which has the first degree of hydrogenation, from the first dehydrogenation reactor (2) into a second dehydrogenation reactor (3, 4), dehydrogenating the carrier material in the second dehydrogenation reactor (3, 4) from the first degree of hydrogenation to a second degree of hydrogenation, and removing by-products from the carrier material.
