Leading Dutch naval architect promotes using ammonia as a fuel in ammonia tanker concept
A new concept for an ammonia tanker powered by an internal combustion engine burning the cargo has been released by C-Job Naval Architects of the Netherlands.
The concept is the product of C-Job Naval Architects lead naval architect Niels de Vries, who has now completed several years of research culminating in his Master’s thesis Safe and effective application of ammonia as a marine fuel at TU Delft.
He said “While this research is unique in its scope and provides a valuable first step towards the application of ammonia as a marine fuel, further research is still required to explore its full potential and feasibility.”
It is his contention that ammonia can be safely and effectively applied as a marine fuel to reduce harmful emissions in the maritime industry.
The ground-breaking research uses a new concept design, an ammonia carrier fuelled by its own cargo, to study the concept of using ammonia as a marine fuel and achieve a significant reduction in greenhouse gas emissions in shipping.
It shows ammonia can be used as marine fuel if a number of safety measures are included in the design.
Mr de Vries said “Reviewing all ammonia power generation options, the solid oxide fuel cell is clearly the most efficient. However, it does have practical challenges as the power density and load response capability are not on an acceptable level yet.”
“Therefore, in the short term applying the internal combustion engine is the way to go.”
“With IMO goals to reduce total annual GHG emissions by at least 50% by 2050 compared to 2008 and eventually fully eliminate harmful emissions, it is of the utmost importance that the global maritime industry looks into renewable fuels like hydrogen, ammonia and methanol,” he said.
C-Job has a track-record of using the latest technologies to design sustainable and future-proof vessels and the company has felt for a number of years that ammonia could be a viable and promising option for a clean and sustainable fuel.
C-Job joined the Ammonia Energy Association last year to intensify collaboration with other industries on this subject to realise its ambition.
Together with Proton Ventures and Enviu, C-Job established a consortium in 2017 to further investigate ammonia as marine fuel.
With the completion of this theoretical research, C-Job has provided a significant contribution to the first phase of the consortium project which will now move towards the next phases, which includes lab testing, pilot and evaluation.
