Methanol Steam Reforming for Hydrogen Production

Methanol steam reforming is a catalytic process that converts liquid methanol and water vapour into hydrogen-rich synthesis gas at temperatures typically between 200 °C and 300 °C. Central to this reaction are copper‐based catalysts, often supported on zinc oxide and alumina, which facilitate the dehydrogenation of methanol and the subsequent water–gas shift reaction to maximise hydrogen yield while minimising carbon monoxide by‐products. Reactor designs range from multi‐tubular packed beds to microchannel and microreactor systems, each addressing challenges in heat management, mass transfer and catalyst utilisation. Advances in reactor modelling and process integration have led to more compact, efficient and responsive systems suitable for portable power applications, stationary fuel‐cell installations and waste‐heat recovery schemes. Global interest in methanol as a liquid hydrogen carrier stems from its high volumetric energy density, ease of storage and distribution, and compatibility with renewable methanol production, making steam reforming a promising route to decarbonised hydrogen for transport, industrial and distributed‐generation sectors.
