> Modeling 5 to 10 GWh electrified containerships, researchers find that 40% of routes today could be electrified in an economically viable manner, before considering environmental costs.

Electric Semi trucks are already happening.

I never argued that some researcher hasnt tried it out. I argued that electric ships and semis are not good solutions. Certainly not with the current grid.

The reason is straightforward, the grid has a certain thermal efficiency, one that ships basically match and semis approach.

I'm not sure what specific grid you are talking about, but yeah, we should decarbonise our grids too. That's happening.

Almost certainly already better in most of the world, and anyway if you're building ship charging stations you can buy new renewable PPAs at the same time to supply power.
