The HyMethShip Concept: An investigation of system design choices and vessel operation characteristics influence on life cycle performance
Poster (konferens), 2020

One potential method to decarbonize the maritime transport sector is by using onboard carbon capture technologies. One such potential future propulsion system is the "HyMethShip - Hydrogen-Methanol Ship propulsion system using onboard pre-combustion carbon capture" concept. In this study we use life cycle assessment to analyse the impact of system design choices on the overall environmental performance of the system. Using the HyMethShip on a vessel is shown to lower climate impact compared to today’s conventional propulsion technologies. The runtime of the carbon capture system and hydrogen leakage are indicated as the main influencers to the environmental performance besides overall system efficiency. The cost of the HyMethShip system is higher than today’s liquid fossil fuel options, but lower than when electro-methanol is used in a conventional engine without applying the HyMethShip concept.
