If methanol is generated from electrolysis, then ok.
If it's from "biofuel", then more deforestation in tropical countries to use land to make methanol from crops. I recall news like this back 5-10 years ago.
I can easily imagine huge floating batteries being very valuable in one place or another.
But we will probably move in the direction of more local production. When the energy is already there, transporting it there, as cheap as it may be is pure cost, for no gain.
