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.
