Safe and Effective Application of Ammonia As a Marine Fuel

Ryan Miller November 13, 2019

To achieve significant reduction in greenhouse gas emissions in shipping and enable ship owner’s to eventually phase them out entirely renewable fuels, such as ammonia, play a crucial role. However, much is still unknown regarding application of ammonia as a marine fuel. An ammonia carrier is used as basis to perform the study identifying the marine technical feasibility and performance of ammonia. Furthermore, a safety analysis is performed on the system level providing the first design principles for ammonia powered vessels. The results of this theoretical research will be presented including an outlook on new developments on the implementation of…

Exploring ammonia's potential as a marine fuel

Ryan Miller October 31, 2018

International shipping is responsible for approximately 90% of the world trade. Looking to the relative emissions, in gram CO2 per ton km, maritime transport score significantly better compared to others like rail, road and airfreight. However, since most of the transport is done by ships the absolute contribution of greenhouse gases (GHG) by the maritime industry is clearly visible. Of all the global emissions the maritime industry is responsible for 3% CO2, 13% SOx, and 15% NOx. To reduce SOx and NOx several regulations are either upcoming or already in play. Current regulations require the sulphur emissions to be less…
