This chapter examines the techno-economic and policy dimensions of hydrogen transportation and trade, highlighting its critical role in enabling the hydrogen economy. Unlike fossil fuels, hydrogen’s low volumetric energy density and unique chemical properties make its movement more complex and costly, requiring tailored infrastructure solutions. The analysis compares major transport modes—pipelines, trucking, shipping of liquid hydrogen and derivatives, and electricity transmission via HVDC—and identifies the conditions under which each is most efficient. Pipelines emerge as the backbone for regional trade, particularly where natural gas networks can be repurposed, while ammonia and methanol are the most viable options for long-distance maritime trade. Blending offers only transitional value, and HVDC lines complement rather than compete with pipelines. The chapter also explores the United Kingdom’s Hydrogen Transport Business Model, which uses a regulated asset base with revenue support to mitigate investment risk. Collectively, these insights underline hydrogen’s likely evolution as a hybrid regional-global traded commodity.
