Internal combustion engines (ICEs) represent the dominant technology in marine propulsion today. If ICEs are to play a role in the decarbonization of shipping, suppliers, regulators, shipowners and engine manufacturers will have to agree on viable alternatives to carbon-based fuel, argues Dr Christos Chryssakis, Business Development Manager at DNV GL.

A growing order book for methanol-fuelled ships shows that the shipping industry sees methanol as a promising alternative fuel. Relying on decades of expertise in the field, DNV explains important criteria to consider.
