It would be far better to use the energy locally to disassociate sea water and turn it into hydrogen, then ship the hydrogen.
They're doing this with the sea change ferry in San Francisco. The hydrogen that it runs on will be created from electricity and seawater at the point if use, on a floating fuel barge. It gets even better, they're using fully green hydroelectric energy from Hetch Hetchy reservoir, so the whole chain is about as green as possible, and is really an example for the rest of the world to follow.

- Schroedingersat 3y agoThe much higher capacity 8000 gross tonne hydrogen carrier can deliver about 1400MWh, after spending 3000MWh filling it up with a bunch of electrolysers then liquifying the hydrogen which you'd have to build a floating platform for. https://en.m.wikipedia.org/wiki/Suiso_Frontier https://en.m.wikipedia.org/wiki/Suiso_Frontier 8000 tonnes of 200Wh/kg batteries is 1600MWh. This is dumb, but hydrogen is much, much dumber.
