Yes, shipping in general, especially long-distance, is a huge issue. But it is only solvable through economics. A solution must be at least as effective and efficient (from a business perspective) as the current dirty oil burning, /and/ significantly better at something to overcome inertia.
My bet would be #nuclear power for that: already being done for decades (mostly military though), and the environment seems ideal (no cooling issues).
