Abstract: Under the background of “dual carbon target”, hydrogen becomes the carrier of clean energy in the future. The current research status of the intensification technology of hydrogen production by methanol steam reforming (MSR) is reviewed in this paper. The characteristics and research progress of MSR micro-reactors are summarized, research on the modification of common catalysts by loading different mass fractions of metals and using other catalyst supports is introduced, and the influence of catalyst application methods on the reaction process is analyzed. Monolithic frame catalysts are mostly used in tubular reactors, coated catalysts are widely used in micro-reactors to create smaller reactors with better hydrogen production performance. Among other technologies for intensifying MSR hydrogen production, the research of a new type of solar thermal reforming hydrogen production reactor filled with phase change heat storage medium is mainly introduced. Finally, recommendations are given for further research and applications of the small-scale reactors for on-demand hydrogen production in different circumstance. In order to solve the gap and instability of green hydrogen production, renewable energy hydrogen production with heat storage medium is a favorable technological means.
