Safe and effective application of ammonia as a marine fuel

To achieve significant reduction in greenhouse gas emissions in shipping and enable ship owners to phase out fossil fuels entirely, renewable fuels, such as ammonia, play a crucial role. Ammonia is considered a balanced solution in terms of volumetric energy density and renewable synthetic production cost compared to other renewable fuels....

A modeling study to investigate performance of SOFC-ICE hybrid systems for marine applications

Emissions restrictions imposed by the International Maritime Organization (IMO) is forcing ship owners and builders to look into alternative fuels and prime movers. The high efficiency of fuel cells could help to decrease emissions in marine power generation. Solid oxide fuel cells (SOFCs) are the most fuel flexible among fuel cells, the high...

Experimental and simulation-based investigation of the performance of a 100 % methanol port-injected spark-ignited engine

The maritime sector faces major challenges with increasing regulations from the International Maritime Organization (IMO) and national regulations for CO2, SOx and NOx. Innovative fuel types for maritime use are now under development by various stakeholders. Methanol shows considerable potential as one of the most promising for implementation in...

Alternative fuel selection and operational performance assessment for a 7000 DWT general cargo vessel: Impact assessment of methanol as alternative fuel on the operational performance of the LABRAX sersies vessels

The current global fleet is still dependent on conventional fuels as energy source to transport goods to various places in the world. These conventional fuels, such as MGO or HFO, emit large amounts of greenhouse gasses and other pollutant emissions. Regulation concerning these emissions becomes stricter every day, therefore institutions and...
