Mitsubishi Shipbuilding Advances Ammonia Handling System for Marine Fuel Utilization

 

Mitsubishi Shipbuilding, a part of Mitsubishi Heavy Industries (MHI) Group, is actively working on the development of the Mitsubishi Ammonia Supply and Safety System (MAmmoSS), a comprehensive ammonia handling system designed to support the use of ammonia as a marine fuel. This initiative aims to significantly reduce greenhouse gas emissions from ships. One essential component of MAmmoSS is the Ammonia Gas Abatement System (AGAS), which safely processes excess ammonia. 

 

Demonstration testing of the AGAS subsystem has commenced at the Nagasaki District MHI Research & Innovation Center. Mitsubishi Shipbuilding will evaluate the system's processing capabilities under various simulated onboard ammonia operation scenarios. Additionally, the company intends to collaborate with related equipment manufacturers to broaden the application of developed ammonia-related technology across various industries, prioritizing safety in the handling of ammonia.

 

MAmmoSS encompasses multiple subsystems, including the AGAS, a high-pressure/low-pressure ammonia fuel supply system (AFSS), and an ammonia fuel tank system. An important feature of MAmmoSS is the modularization of these subsystems, allowing for customizable configurations suited to onboard plants containing multiple engines and boilers.

 

Aligned with MHI Group's energy transition strategy, Mitsubishi Shipbuilding aims to leverage its experience in ammonia handling and shipbuilding to supply safe and reliable products. As a maritime system integrator, the company will contribute to the global reduction of environmental impact by offering shipbuilding engineering services for ammonia-fueled vessels, alongside construction support and related services to meet diverse customer needs.
