A major cruise ship operator, Holland America Line, has embarked on a long-term biofuel test on its flagship vessel, Rotterdam. The ship is utilizing “100 percent low carbon intensity biofuel” while sailing within the Norwegian World Heritage Fjords. Before departing from the Port of Rotterdam, the Netherlands, on April 27, the vessel bunkered this biofuel. During its time in the Fjords, one of the ship’s four engines will run on low carbon intensity oil derived from organic waste or residues, certified in accordance with the EU Renewable Energy Directive.
