The invention provides a hydrogen pump for vacuum insulation jackets for a vessel or a pipe which holds or through which flows a hydrogen-containing medium at temperatures such that hydrogen permeates into the jacket, comprising a palladium or palladium alloy membrane exposed on one side to an oxidizing atmosphere and on its other side to the evacuated space within the jacket, wherein the membrane enables the flow of the hydrogen from the evacuated space through the membrane into the oxidizing atmosphere.

A hydrogen pump for vacuum insulation jackets for a vessel or pipe which holds or through which flows a hydrogen-containing medium at temperatures such that hydrogen permeates into said jacket, comprising a palladium or palladium alloy membrane exposed on a first side to an external oxidizing atmosphere having a relatively high hydrogen partial pressure, and on a second side to the evacuated space having a relatively low hydrogen partial pressure within said jacket, wherein said membrane enables the flow of said hydrogen from said evacuated space through said membrane into said oxidizing atmosphere and said palladium membrane catalyzes the reaction of said hydrogen permeated through said palladium membrane and oxygen present in said external atmosphere to form water to reduce the hydrogen partial pressure at said second side of the membrane creating a hydrogen gradient that moves said hydrogen from said evacuated space to said external atmosphere.
