Wärtsilä and Simon Møkster Shipping will explore the feasibility of using ammonia as the main fuel in dual fuel engines. Currently Møkster's fleet operates on LNG. In Japan, NYK Line, Japan Engine Corporation, IHI Power Systems, Nihon Shipyards and ClassNK will all collaborate on a demonstration project of ammonia-powered vessels in Japan. First announced in 2020 with three vessel concepts, two of the three vessel designs now have a commercialisation schedule fully defined (the A Tug and the AFAGC).
