I’m not sure where you are based but in the UK the pipeline infrastructure is already in place.. You aint going to get ships etc running on H2 without the infrastructure world wide in place to do it and tbh I'd love to see it..
The National Tranmission System (NTS) is the network of gas pipelines that supply gas to power stations and large industrial users from terminals situated on the coast, and to gas distribution companies that supply commercial and domestic users.
This network can be be used to transport hydrogen to storage tanks and homes.
