World First Full Scale ‘Ammonia as Fuel’ Marine Four-Stroke Engine Test

While there is no consensus on the marine industry ‘fuel of the future’ that will meet ever tightening international emission mandates, a group of organizations has commenced what it is calling the world’s first long-term, full-scale, testing of ammonia as a fuel in a marine four-stroke combustion engine. Wärtsilä, Knutsen OAS Shipping AS, and Repsol, and the Sustainable Energy Catapult Center, have teamed for the effort, as ammonia offers promise as a carbon-free fuel for marine applications, to meet the IMO’s mandate of cutting emissions from shipping by at least 50 percent by 2050.
