J-ENG Launches Marine Engine Fueled by Ammonia

Japan Engine Corporation (J-ENG) has announced the completion of its first full-scale ammonia-fueled engine. The engine is due to be shipped to Japan Marine United (JMU)’s Ariake Works for installation on an ammonia-fueled ammonia carrier (AFMGC) which is currently under construction at the facility. The vessel is scheduled to enter service in November 2026.

PSR Analysis: J-ENG’s first domestically produced ammonia fuel engine is a significant milestone as Japan strives to lead the way in marine decarbonization technology. Ammonia emits no CO₂ during combustion, making it a strong candidate for alternative fuels under the stricter IMO GHG regulations.
