This is one area where we’re guaranteed to see a fuel being used. Either synfuels, e-fuels, ammonia, hydrogen, etc., it will have to be something that can be carried into the port from elsewhere. There’s no other way around this problem.

For long distance shipping anyway.

These are river barges in the article.

Long distance shipping is currently mostly burning "resid" it's the bottom-of-the-bottom or the barrel. It's 3.5% sulphur and it's not worth much more than the cost of transporting it from the refinery to the port.

The idea that shipping companies will go straight for the expensive options of as synfuel, green ammonia (the deaths alone for the crew will be horrific), or green hydrogen is absurd.
