The relevant question is not: “Could airships move full shipping containers?” but rather: “Could airships find an economic niche and turn a profit in that niche?” Perhaps they move cargo in lighter containers (fiberglass, aluminum, etc.), or in moving high-volume low-mass cargoes like prefabricated cylindrical tanks, or wind turbine blades. Perhaps they specialize by replacing “ice road” transport to tundra or arctic locations. Or to jungle locations - mining or drilling operations. Maybe they replace sky-crane helicopters rather than replacing barges, container ships, trains, or trucks. We have mostly replaced sailing ships, canal narrow boats, stagecoaches, and the pony express. Nothing is forever. We’ll know that H2 airships have really arrived when they are mentioned in country music.
