Seems like this might be a better solution for shipping than for trucks. Batteries are not really a viable solution for shipping, except on short routes. They're probably stuck with hydrocarbon fuels, but this might work, and the extra mass of CO2 carried wouldn't really be a big deal for a ship. Probably won't work with current dirty bunker fuel though, as I expect that contains too many contaminants; it would need the fuel to be cleaned up a lot first so I wouldn't expect the shipping industry to be overly enthusiastic.

77% of semi truck routes are 250 miles or less, a distance easily covered by today’s EV technology.

What fraction of the total semi truck traveled miles are on those short routes?

Also, what percentage of semi trucks are only utilized on these short routes?

A big thing in fleets is flexibility, and if you're requiring a much larger fleet, or two fleets, to do the same job that's not workable in many cases.

The range of the Tesla semi is supposed to be 500 miles. Others can be expected to be similar. That's enough that if you're even partially charging every time you stop to eat or sleep you'll never run out.

A modern EV sedan can do 250 miles, but how far can that tech drive a semi truck? I'm guessing it's quite a lot less.

New regulations coming in effect in 2020: [1]

"What is the current regulation on SOx in ships emissions and by how much is that going to be improved?

We are going to see a substantial cut: to 0.50% m/m (mass by mass) from 3.50% m/m."
