Fortunately, we don't burn bunker C anymore and haven't for a lot years. The drive to decarbonization of shipping is obviously a global initiative. It will take a number of factors all coming together. Frankly, the ports really won't have the ability to drive that. They will need to be ready to respond for what the new fuels are and the production of those fuels.
Ports need to be ready. They need to have the land available, because all of the fuels will require massive land use if that port is to be considered a bunkering port. Many won't. The whole bunkering network around the world will dramatically change as we transition to new fuels. There will probably be more bunkering ports required. There'll be a whole redistribution of bunkering around the world. How that will look remains to be seen.
I think that ports are keeping a very close eye on it, particularly the European and Asian ports. They're making some very good strides, but it is extremely expensive, as you can imagine.
