By designing holistic, integrated approach to power use is going to be a key our solutions around LNG we are making them as future-proof component of ef? cient container shipping in the future.” as possible: HVO (Hydrotreated Vegetable Oil), biogas and syn- thetic methane can all be used by dual fuel LNG engines without any major modi? cations, and an LNG system designed the right way can be converted for use with ammonia, albeit with up- rated and increased tank capacity to cope with the lower energy density of the fuel. Of course, a dual fuel engine can also burn

MGO, so that gives six possible fuels to choose from.” “Choosing the right fuel is going to be important,” said Gjer- pe. “But we’re also looking at the wider picture – how to make sure that get the best from your fuel. There are still ef? ciencies to be made, and the use of PTOs is a key enabler for this. Our research is quite clear – propulsion engines and generators sets are often underutilised, which means that they’re not running ef? ciently. PTOs allow use of spare capacity, meaning fewer
