ClassNK reports that the world’s first commercial-use ammonia-fueled tugboat, Sakigake, 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%.
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’s New Energy and Industrial Technology Development Organization (NEDO).
The development project for the ammonia-fueled tugboat vessel started in October 2021 as part of the Green Innovation Fund Project; “Development of vessels equipped with domestically produced ammonia-fueled engines.“ It was completed in August 2024, becoming the world’s 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.
NYK and IPS analyzed the ammonia co-firing and GHG-reduction rates during vessel operations and confirmed them to consistently
