Hoegh Autoliners expects to build its next round of four large dual-fuel car carriers as ammonia-diesel burners, and skip LNG entirely as a fuel source.

The development comes after engine maker MAN Energy Solutions said it can deliver large ammonia-burning marine engines by the fourth quarter of 2024.

That will come in time for installation in ships nine to 12 in the series of 9,100-ceu car carriers under construction at China Merchants Heavy Industry Jiangsu (CMHI Jiangsu).
