> these ships will have to burn cleaner fuel The big freighters run on something pretty close to crude oil, it's basically unrefined. Are they really passing regulations requiring them to run on refined processed fuel? That will increase the cost of shipping dramatically. Not sure if the engines can even run on normal diesel. https://news.ihsmarkit.com/press-release/energy/new-low-sulfur-requirements-marine-bunker-fuels-causing-scramble-refiners-and-s https://news.ihsmarkit.com/press-release/energy/new-low-sulf... Well, it appears they are. What will happen then to the high density waste oil from the refining process that is currently used for freighters? Without them burning it or existing as a market, the oil will still exist as a byproduct of refining. Will it just be dumped somewhere? > researchers expect that on-board ship scrubbers, devices that clear harmful pollutants from exhaust gas, will be the primary compliance path for ships, which could continue to burn higher-sulfur fuels This is probably the only option. Or switching to reactors.
