MAN Energy Solutions has announced one of the first deployments of its ammonia two-stroke engine will take place in Japan. Mitsui E&S will construct the MAN B&W 7S60ME dual-fuel engine, with Imabari Shipbuilding to then install it aboard a Newcastlemax bulk carrier, along with an integrated SCR catalytic converter to treat engine NOX emissions. The news underscores significant momentum for the deployment of marine ammonia engines, with Wärtsilä, WinGD and Mitsubishi Shipbuilding also engaged in ongoing projects.

Maritime Ammonia: ready for demonstration
At least four major maritime ammonia projects have been announced in the last few weeks, each of which aims to demonstrate an ammonia-fueled vessel operating at sea. In Norway, Color Fantasy, the world's largest RORO cruise liner, will pilot ammonia fuel. Across the broader Nordic region, the Global Maritime Forum has launched NoGAPS, a major consortium that aims to deploy "the world's first ammonia powered deep sea vessel" by 2025. In Japan, a new industry consortium has launched that goes beyond on-board ship technology to include "owning and operating the ships, supplying ammonia fuel and developing ammonia supply facilities." And the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), which published its roadmap last month, aims to demonstrate ammonia fuel on "an actual ship from 2028" — specifically, a 80,000 dwt ammonia-fueled bulk carrier.
