Mitsubishi Shipbuilding Completes Delivery of Ammonia Fuel Supply System for Large, Low-Speed Two Stroke Marine Engines

Tokyo, May 24, 2023 – Mitsubishi Shipbuilding Co., Ltd., a part of Mitsubishi Heavy Industries (MHI) Group, has completed delivery of an ammonia fuel supply system for large, low-speed two stroke marine engines, to Japan Engine Corporation (J-ENG), a manufacturer of marine engines based in Akashi City, Hyogo Prefecture.

J-ENG is currently conducting tests of ammonia fuel under various conditions utilizing an experimental, large-scale, low-speed two stroke marine engine located at the MHI Research & Innovation Center, Nagasaki District in Japan. The ammonia fuel supply system supplied by Mitsubishi Shipbuilding has been installed at the Nagasaki District facility, and supplies the ammonia fuel used to conduct the tests.

Ammonia, which emits no CO₂ when combusted, is attracting attention as a fuel that contributes significantly to the reduction of GHG (greenhouse gas) emissions in the maritime industry, and is expected to be utilized as a stable clean energy in the future. Mitsubishi Shipbuilding aims to contribute to reducing GHG emissions in the maritime industry by manufacturing and supplying ammonia fuel supply systems for ships.

Going forward, according to MHI Group’s strategy of advancement of the energy transition, Mitsubishi Shipbuilding will strive to promote decarbonization of the maritime industry as well as to contribute to realizing a carbon-neutral society and reduction of environmental load on a global scale, by utilizing its technologies and expertise in ammonia handling accumulated through its long experience in building multi-gas carriers for transporting LPG and ammonia.
