Mitsubishi Shipbuilding Co., Ltd., a part of Mitsubishi Heavy Industries (MHI) Group, is currently developing the Mitsubishi Ammonia Supply and Safety System (MAmmoSS®), an ammonia handling system to support the utilization of ammonia as marine fuel, which is attracting attention as a means of significantly reducing greenhouse gas (GHG) emissions from ships. As part of this development project, Mitsubishi Shipbuilding has begun demonstration testing of the Ammonia Gas Abatement System (AGAS), a subsystem of MAmmoSS® to safely treat surplus ammonia.
Ammonia Gas Abatement System (AGAS) demonstration facility
Using the AGAS demonstration facility at the Nagasaki District MHI Research & Innovation Center, Mitsubishi Shipbuilding will conduct demonstration tests of the processing performance under various scenarios simulating onboard ammonia operations and as well as explore broadening the range of maritime industry through collaboration with related equipment manufacturers, developed ammonia related technology will be applied for various industries to support its safe handling.
MammoSS® comprises several subsystems in addition to AGAS, including a high-pressure/low-pressure ammonia fuel supply system (AFSS) and an ammonia fuel tank system. A key feature of MAmmoSS® is that each of these subsystems can be modularized, allowing Mitsubishi Shipbuilding to provide the optimal modular configuration in a package for onboard plants consisting of multiple engines and boilers.
