Hybrid electric marine systems contain many electronic control components linked by a controller area network (CAN) in a bus network topology. Testing the network appropriately can help uncover problems caused by bad CAN system design or electrical component aging. These problems can be latent faults, requiring only one component failure to cause total system failure. Methods including fault insertion testing and close examination of the CANbus electrical signal will be discussed to show the benefits of such in-depth inspection. A case study from an actual hybrid electric drive system on a yacht will be presented.

Safe and effective application of ammonia as a marine fuel

Niels de Vries
Lead naval architect
C‑Job Naval Architects
Niels de Vries, lead naval architect at C-Job Naval Architects, won the Maritime Designer Award 2019 for his research on the safe and effective application of ammonia as a marine fuel. His research showed that in the long term the Solid Oxide Fuel Cell is the best option as it is the most efficient, but currently has practical challenges which in time may be overcome. However, a three step plan could see step one as, ammonia and marine diesel in an (Compression Ignition) Internal Combustion Engine (ICE). The second stage would be an ICE using ammonia hydrogen mixtures and then the third and final stage an SOFC using ammonia. In this presentation Niels will outline the essential details of how to achieve the ultimate goal.

Panel Discussion

Will hydrogen become a must-have marine fuel?

Hydrogen-energy technologies – maturing thanks to road transportation applications – have reached a first level of cost competitiveness, qualifying them for demonstration projects in waterborne applications. If their intrinsic limitations (e.g. energy density) cast doubts on their ability to constitute a radical alternative to existing fuels, the question of the precise role they could play in the sector is at stake. This role is also likely to be influenced by local characteristics and tax regulations. Through the experience of MARANDA and Flagships, this discussion will offer a few insights to guide those considering hydrogen and fuel cells for investment.
