ClassNK reports that the world\u2019s first commercial-use ammonia-fueled tugboat, Sakigake<\/em>, has successfully completed a three-month demonstration voyage, during which it engaged in tugboat operations in Tokyo Bay and achieved a GHG-emission reduction of up to approximately 95%.<\/p>\n The vessel was completed by Nippon Yusen Kabushiki Kaisha (NYK) and IHI Power Systems Co., Ltd. (IPS) on August 23, 2024, in cooperation with ClassNK as part of a Green Innovation Fund Project under Japan\u2019s New Energy a<\/a>nd Industrial Technology Development Organization (NEDO).<\/p>\n The development project for the ammonia-fueled tugboat vessel started in October 2021 as part of the Green Innovation Fund Project; \u201cDevelopment of vessels equipped with domestically produced ammonia-fueled engines.\u201c It was completed in August 2024, becoming the world\u2019s first commercial-use ammonia-fueled vessel, with NYK Group company Shin-Nippon Kaiyosha engaged deploying it on a three-month demonstration voyage while conducting tugboat operations in Tokyo Bay.<\/p>\n NYK and IPS analyzed the ammonia co-firing and GHG-reduction rates during vessel operations and confirmed them to consistently exceed 90% and rise to approximately 95% in each of the main engine load ranges, as shown in the table below.<\/p>\n The demonstration tests while in tugboat operation are the world\u2019s first trial of its king, confirming, says NYK, that ammonia is one of the most viable and promising options as a next-generation fuel for vessels.<\/p>\n The vessel will continue to be used for tugboat operations in Tokyo Bay, and the project will continue to accumulate knowledge related to the development and operation of ammonia-fueled vessels.<\/p>\n In addition, NYK, Japan Engine Corporation,<\/a> IPS, and Nippon Shipyard Co., Ltd. are working together to develop an ammonia-fueled ammonia gas carrier, which is scheduled to be delivered in November 2026.<\/p>\n The post World\u2019s first commercially-operational ammonia-fueled tugboat completes demo voyage<\/a> appeared first on Marine Log<\/a>.<\/p>\n<\/div>\n![\"mmonia-fuel](\"https:\/\/i0.wp.com\/www.marinelog.com\/wp-content\/uploads\/2025\/03\/1470cf00-805f-c5b7-2071-eb3d54465963.jpg?resize=700%2C217&ssl=1\")
