NYK and IHI Power Systems in collaboration with Nippon Kaiji Kyokai (ClassNK) has completed the ammonia-fueled tugboat Sakigake, the world’s first ammonia-fueled vessel for commercial use. Over a three-month demonstration period, the NYK Group company Shin-Nippon Kaiyosha will operate the vessel in Tokyo Bay.
The vessel was part of the Green Innovation Fund Project launched in October 2021 by Japan’s New Energy and Industrial Technology Development Organization (NEDO) to develop vessels equipped with domestically produced ammonia-fueled engines.
As part of NEDO’s Green Innovation Fund Project, NYK is also involved in the development of an ammonia-fueled medium gas carrier (AFMGC) in partnership with Japan Engine Corporation, Nihon Shipyard Co., Ltd., IHI Power Systems, and ClassNK. This vessel is expected to be delivered in November 2026.
