The analysis compares LNG, marine gas oil, very low sulphur fuel oil and heavy fuel oil used in marine engines in the LNG tanker and cruise sectors. However, results varied widely depending on engine technology. High-pressure dual fuel (HPDF) machinery came out top but the ICCT estimates that only 90 of the 750-plus LNG-fuelled ships in ...
