Japanese Companies Advancing Ammonia Fuel Transport Solutions for Maritime Industry

A partnership of Japanese companies is making significant progress in developing ammonia transport for use as a fuel in various industries, including the maritime sector. The project, involving Mitsubishi Shipbuilding Co., Mitsui O.S.K. Lines, and Namura Shipbuilding Co., recently received initial design approval from ClassNK. This Approval in Principle (AiP) signifies that the basic design drawings and risk assessment have met the necessary standards for moving forward with the development process. The partners have gone above and beyond in detailing the designs to meet future demands and market potential as a transitional fuel for power plants and marine transportation.

The focus of the project is on designing a large ammonia carrier with an engine that utilizes ammonia as the main fuel source. This innovative approach aims to reduce greenhouse gas emissions from the vessel and increase efficiency in marine transport. The design also incorporates the Wind Challenger rigid sail system, developed by Mitsui O.S.K. Lines and Oshima Shipbuilding Co., which was first deployed in 2022. The vessel is expected to be larger than conventional Very Large Gas Carrier/Very Large Ammonia Carrier (VLGC/VLAC) vessels, ensuring compatibility with existing infrastructure and port entry restrictions at major power plants in Japan.

The partners anticipate that the first vessels based on this revolutionary design could be constructed in the second half of this decade. The project’s emphasis on sustainability and efficiency aligns with the growing global interest in alternative fuels and environmentally friendly transportation solutions. By leveraging ammonia as a fuel source, the partnership aims to address emissions challenges in the maritime sector while meeting the evolving needs of the industry and market demands.
