> Even electric shipping is possible, but would require substantial infrastructure investments (e.g. buoys in the middle of large oceans every so often connected to trans-oceanic power cables so the ships can recharge regularly).

A lot has been said about hydrogen powered vehicles, but I don't think it will work for general use. Where it may be useful though is in 'industrial' transport.

It's unlikely we'll see hydrogen 'gas stations' for normal people, but for ships, trucks, and maybe airplanes, setting up the infrastructure may be more practical (fewer, more concentrated stations).
