Execution of Memorandum of Understanding for Joint Development of Ammonia Fueled Bulk Carriers among 6 parties

MITSUI E&S Co., Ltd. (headquartered in Chuo-ku, Tokyo; President: Takeyuki Takahashi; hereinafter "MITSUI E&S"), announced today that, together with ITOCHU Corporation (hereinafter "ITOCHU"), Nihon Shipyard Co., Ltd. (hereinafter "Nihon Shipyard"), MAN Energy Solutions (hereinafter "MAN"), Kawasaki Kisen Kaisha, Ltd. (hereinafter ""K" Line"), and NS United Kaiun Kaisha, Ltd. (hereinafter "NS United") has executed a Memorandum of Understanding ("MOU") regarding joint development effort for the commercialization of ammonia fueled ships.

Ammonia is advancing as a key zero-emission marine fuel solution and it will greatly contribute to Greenhouse Gas (GHG) emissions reduction if ammonia can be commonly used as a marine fuel. The development and commercialization of ammonia dual fueled engine on which ammonia fuel is used for a primary fuel (Ammonia Fueled Engine) is essential for widespread use of ammonia fueled ship ("Ammonia-Fueled Ship"). In particular, the ensuring of safety in the handling of toxic ammonia and the confirming of stable operations at sea are important milestones on the road to the social implementation. This MOU is based on the premise that 200,000 deadweight ton class bulk carriers to be built by Nihon Shipyard will be equipped with Ammonia Fueled Engines being developed by MAN and manufactured by MITSUI E&S as a "pilot project" prior to commercialization, and that the necessary operational data will be collected after the delivery of the ships, for the commercialization of Ammonia Fueled Engines and Ammonia-Fueled Ships in cooperation with other parties involved.

The execution of this MOU is an important milestone for the implementation of Ammonia-Fueled Ships, a new challenge being taken on by the maritime industry, and also an important step in the ongoing implementation of the "Integrated Project" being facilitated by ITOCHU.
MITSUI E&S and partners will proceed with the development of the Ammonia Fueled Engines and Ships based on this MOU, and aim to begin its social implementation once it is ready in accordance with the "Integrated project for development and social implementation of ammonia fueled ships" which was adopted to the "Green Innovation Fund Project / Development Project for Next-Generation Ships / Development of Ammonia Fueled Ship", a project publicly offered by New Energy and Industrial Technology Development Organization (NEDO) in October 2021.

In accordance with this MOU, MITSUI E&S will manufacture and supply the world's first two-stroke MAN B&W ammonia dual fueled engine and will develop and supply related system. As a marine propulsion system supplier, MITSUI E&S will continue to contribute to the realization of a decarbonized society in the field of marine logistics.
