Im guessing that container ships don’t need much refueling? If the ship runs into issues I wonder if they have to ground it until they can ship the methanol to it.

Apparently not; large container ships have a range of 10.000 - 20.000 miles on a single tank of fuel. These things are huge, and I can imagine they don't even need to compromise on storage space for fuel tanks (just like planes have fuel in the wings so their cargo capacity is maximised)

They can do that because they can carry 2-4.5 million gallons of fuel; 16,000 cubic meters.

That's taking some space somewhere, usually between the double hulls on the bottom of the ship.

It's a dual fuel ship - it can still run on fuel oil.

so is this methanol in harbor / emissions zones and fuel oil at sea? Does it run on diesel too?

The main engine can run on fuel oil and methanol/LPG. They claim they can have 40k km of range on methonol.

What they actually do in operation is of course different from what they're able to do.

yeah I wonder how the costs compare at current day prices. they aren't going to run methanol if its more expensive.

They will if they can get someone to pay the difference; either because of carbon credits or advertising or whatever.
