Application Status and Function Analysis of Methanol in Hydrogen Transportation Energy Supply

Methanol, with its abundant production, mature synthesis process, well-established storage and transportation infrastructure, and no need to return the dehydrogenated product, is considered to be an ideal hydrogen carrier, is expected to play a great role in the energy transition of the transportation sector and the construction of a hydrogen transportation system. This paper focuses on the hydrogen energy supply system using methanol as a carrier, briefly introduces the basics of methanol production and transportation, and then focuses on the different routes of using methanol in hydrogen transportation infrastructure and vehicles from the perspectives of technology, economy, safety, and commercialization process. Finally, the impacts of the different routes of introducing methanol on hydrogen transportation are compared and analyzed, and the role of methanol in the energy supply of hydrogen transportation is elaborated.
