Japanese Ammonia-Fuelled Engine Slated for Delivery in October
Japan Engine Corporation (J-ENG) has announced that its full-scale, two-stroke engine has begun ammonia co-firing operations, marking a key milestone ahead of its scheduled delivery in October.
The engine will be installed on a gas carrier, J-ENG said in a statement on its website on Monday.
This development builds on the groundwork laid in May 2023, when J-ENG launched the world’s first ammonia co-firing operations on a large, low-speed, two-stroke test engine.
Over the past year and a half, the company has leveraged data and operational experience from the testbed to fine-tune combustion performance, improve ammonia handling systems and validate safety protocols.
These learning have been used to design and commission the full-scale ammonia engine unit.
In addition to the 50 cm cylinder bore engine, J-ENG is also developing an ammonia engine with a 60 cm cylinder bore, designed to power larger ships.
In December 2023, NYK Line, IHI Power Systems, Nihon Shipyard and J-ENG signed an agreement to build a 40,000 m3 ammonia-fuelled gas carrier, with delivery scheduled for November 2026.
