Hydrogen is widely seen as energy carrier of the future. Different technologies are under development to produce hydrogen at competitive cost but with significantly reduced carbon footprint. Two conventional technologies, namely, methane steam reforming and coal gasification, are compared based on product cost and carbon footprint with four new technologies, i.e., metal-oxide cycle, water electrolysis, biomass gasification, and methane pyrolysis. To evaluate the carbon footprint for methane pyrolysis, system extension and differential methods are applied. For the boundary conditions selected here, methane pyrolysis yields very good values for product cost and carbon footprint. Therefore, a cross industry technology development of methane pyrolysis was initiated.
