Carbon Dioxide‐Free Hydrogen Production with Integrated Hydrogen Separation and Storage

An integration of CO 2 ‐free hydrogen generation through methane decomposition coupled with hydrogen/methane separation and chemical hydrogen storage through liquid organic hydrogen carrier (LOHC) systems is demonstrated. A potential, very interesting application is the upgrading of stranded gas, for example, gas from a remote gas field or associated gas from off‐shore oil drilling. Stranded gas can be effectively converted in a catalytic process by methane decomposition into solid carbon and a hydrogen/methane mixture that can be directly fed to a hydrogenation unit to load a LOHC with hydrogen. This allows for a straight‐forward separation of hydrogen from CH 4 and conversion of hydrogen to a hydrogen‐rich LOHC material. Both, the hydrogen‐rich LOHC material and the generated carbon on metal can easily be transported to destinations of further industrial use by established transport systems, like ships or trucks.
