| Sumario: | Maritime shipping plays a key role in world economic growth; however, it’s one of the most criticised mode of transportation due to emissions. To control this, many regulations including IMO Annex VI has been enforced. Furthermore, EU is planned to impose its EU ETS starting from January 2024 on ships, stringing the regulations even more. Therefore, there is a continuous search of appropriate alternative fuel for maritime industry. This thesis aims to study the possible alternative fuel technologies and later investigate fuel cell hybrid propulsion system for a selected case of ferry ALMADENSE running on Tagus River in Lisbon, Portugal. To assess the hybrid FC propulsion system, a SIMULINK model based on numerical and fluid simulations is developed along with power and energy management systems. Components of the system are simulated for changing environmental conditions throughout a year. A diesel system is also designed & simulated under same conditions enabling a fair comparison. In the thesis, three possible scenarios are discussed, 1st is doing business as usual, 2nd is replacing the diesel engine with hybrid FC system and lastly replacing the whole ship with a new one based on hybrid FC system. Selection is done w.r.t. two fronts namely, environmental and economical. The results show that replacing the current ship with a new hybrid FC ship by 2026 would be the optimum solution. The resultant ship would not only save environmental pollution but also will be economically beneficial overall as compared with 2nd case. |
