Fig. 3: Global service provided by technology for international and domestic shipping and long-haul and short-haul aviation across the four scenarios.
From: Integrated assessment modeling of a zero-emissions global transportation sector

Note the different y-axis scales and units for each mode; units are trillion passenger-kilometers (pass-km) for aviation and trillion ton-kilometers (ton-km) for shipping. For aviation, hydrogen technologies employ hydrogen combustion turbines, while for shipping, hydrogen fuel cell electric vessels are modeled. BEV battery electric vehicle, FCEV fuel cell electric vehicle.
