System analysis and optimization of a hybrid marine propulsion system for low carbon shipping
The offered position will contribute to the Horizon2020 HyMethShip consortium. HyMethShip system innovatively combines a membrane reactor, a CO2 capture system, a storage system for CO2 and methanol as well as a hydrogen-fueled combustion engine into one system. The proposed solution reforms methanol to hydrogen, which is then burned in an internal combustion engine that has been upgraded to burn multiple fuel types and specially optimized for hydrogen use. The dramatic CO2 reduction is a result of using renewable methanol as the energy carrier and implementing pre-combustion CO2 capture and storage on the ship. The renewable methanol fuel bunkered on the ship is ideally produced on-shore from the captured CO2, thus closing the CO2 loop from the ship propulsion system. For medium and long distance waterborne transport, the HyMethShip concept is considered the best approach available that achieves this level of CO2 reduction and is economically feasible.
