State of the Art of Hydrogen Production via Pyrolysis of Natural Gas

Abstract Fossil fuels have to be substituted by climate neutral fuels to contribute to CO 2 reduction in the future energy system. Pyrolysis of natural gas is a well‐known technical process applied for production of, e. g., carbon black. In the future it might contribute to carbon dioxide‐free hydrogen production. Production of hydrogen from natural gas pyrolysis has thus gained interest in research and energy technology in the near past. If the carbon by‐product of this process can be used for material production or can be sequestrated, the produced hydrogen has a low carbon footprint. This article reviews literature on the state of the art of methane / natural gas pyrolysis process developments and attempts to assess the technology readiness level (TRL).
