NYK Takes Delivery Of Ammonia-Powered Engine For World's First Commercial Ammonia-Fueled Ship

Japanese shipping company NYK has taken delivery of a domestically built ammonia-powered engine to be installed in a tugboat, which is set to become the world’s first commercially functioning ammonia-fueled ship.

The engine, developed jointly with ClassNK and IHI Power Systems as part of the Green Innovation Fund Project in the Japanese New Energy and Industrial Technology Development Organization (abbreviated as the NEDO), was delivered to the NYK on February 1.

It will be installed on an ammonia-fueled tugboat scheduled for its estimated delivery in June 2024. The tugboat is now being converted to run on ammonia fuel, not LNG. NYK embarked on converting an LNG-fueled tugboat named the Sakigake to an ammonia-operated tugboat with the Oppama factory of the Keihin Dock Co. in Oct last year.

To replace the entire engine, including the primary engine and the fuel tank, the vessel’s engine room will be cut to eliminate the LNG equipment and install new ammonia-fueled machinery.

The engine was examined at the IHI Power SySystems’ta Plant (the Gunma Prefecture) to ensure zero emissions from unburned ammonia as well as nitrous oxide (N2O), which has a greenhouse impact of approximately 300 times higher than carbon dioxide, per NYK.
