Mitsui OSK Lines (MOL) is to fit one of its bulkers with a hydrogen-fuelled engine as part of a trial with marine engine manufacturer Japan Engine Corp (J-ENG).

The trial will see a low-speed, two-stroke hydrogen-fuelled engine fitted on board the vessel, which will be operated by the Japanese shipping giant's subsidiary, MOL Drybulk.

MOL claims this is the first time such a system will be installed as a main engine on board "large" ocean-going or coastal vessels.
