In this paper, the applicability of methane decarbonization in the PtG concept has been analyzed on a general sense. Some development is still needed to put into practice this technology, mainly to improve from the laboratory scale to the demonstration and industrial scale. Hydrogen production rates should be up-scaled from a few mL/min to some ton/h with economically viable processes that could compete with existing hydrogen production processes, either from methane (as steam reforming) or electrolysis.
