Mitsubishi Shipbuilding Co., Ltd., part of Mitsubishi Heavy Industries (MHI) Group, has shipped an ammonia fuel supply system (AFSS) and an ammonia gas abatement system (AGAS) for Japan Engine Corporation (J-ENG). Both systems are designed for J-ENG's first ammonia-fuelled marine engine model 7UEC50LSJA-HPSCR and represent the first units produced by Mitsubishi Shipbuilding. Commissioning work will begin in due course.
The AFSS supplies ammonia fuel to the engine in a stable and safe manner, while the AGAS safely 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, enhancing operational efficiency and safety.
The early market introduction of these systems will enable onboard verification combining J-ENG's 7UEC50LSJA-HPSCR ammonia-fuelled engine. The move is regarded as a pioneering step in next-generation advanced maritime propulsion. Ammonia fuel stands out as one of the most promising alternative fuel options for the transition to carbon-free maritime propulsion.
