New Delhi, May 17, 2023: NYK Line, IHI Power Systems Co., Ltd. (IHI Power Systems), Nihon Shipyard Co., Ltd. (Nihon Shipyard), Japan Engine Corporation, and Nippon Kaiji Kyokai (ClassNK) (hereafter, “the consortium”) are pleased to announce that the world’s first four-stroke ammonia-fueled engine has successfully completed a land-based test for the stable combustion of fuel ammonia having an 80% co-firing ratio as part of a demonstration project for the commercialization of vessels equipped with a domestically produced ammonia-fueled engine.
Overview
This initiative concerns the development of vessels equipped with a domestically produced ammonia-fueled engine. It was initiated in October 2021 by NYK, Japan Engine Corporation, IHI Power Systems, and Nihon Shipyard as part of the Green Innovation Fund Project* of the New Energy and Industrial Technology Development Organization (NEDO).
In April 2023, IHI Power Systems commenced operational tests at its Ota plant (Gunma Prefecture) on a 280 mm bore** four-stroke ammonia-fueled marine engine for the main engine of coastal vessels (i.e., ammonia-fueled tugboats, hereafter “A-Tug”).
