Mitsubishi Shipbuilding ships first marine ammonia fuel systems amidst maritime decarbonisation push

Units were delivered for J-ENG ammonia engine model.

Mitsubishi Shipbuilding has shipped its first ammonia fuel supply system (AFSS) and ammonia gas abatement system (AGAS) for Japan Engine Corporation (J-ENG) for use with an ammonia-fuelled marine engine model, according to a press release.

The early market introduction of these systems will enable onboard verification combining J-ENG's ammonia-fuelled marine engine model 7UEC50LSJA-HPSCR, a first mover in next-generation advanced fueled engines, with Mitsubishi Shipbuilding's AFSS and AGAS. Commissioning work will begin in due course.

AFSS delivers ammonia to the engine, whilst the AGAS processes surplus ammonia generated during fuel switching from ammonia to conventional fuel oil.

Both systems support remote operation and automatic control through an integrated control system.
