Résumé

In 2024, the International Maritime Organization (IMO), through MEPC (82) resolutions, adopted a revised and increasingly ambitious strategy to reduce and eventually eliminate greenhouse gases (GHGs) from the international maritime shipping sector. Concurrently, the European Union, under its "European Green Deal," has imposed emission fees on every vessel trading with or within EU waters, potentially doubling fuel-related costs within a few years. Additional regulations under discussion, along with green financing initiatives like the Poseidon Principles, will further pressure the shipping industry to decarbonize. A fundamental aspect of the energy transition is expanding the availability of alternative fuels in ports, with LNG bunker vessels expected to play a major role. However, potential owners face the risk of investing in assets that may become stranded or severely limited before completing their lifecycle. Therefore, it is essential to ensure that newly constructed vessels can adapt and upgrade to maintain full operativity throughout their projected lifespan. As new technologies such as fuel cells and others reach maturity and scale, it is essential that newly designed vessels adopt a modular electrical approach to power distribution, enabling the easy integration of any new technologies as they become available in the future. This paper aims to explore how hybrid electric propulsion systems effectively address three key concerns in the maritime industry: adaptability to new fuels and new technologies, compliance with new legislation, and operational safety. The study compares hybrid electric propulsion systems with other alternatives for LNG bunker vessels. The analysis will consider key efficiency parameters, including overall vessel efficiency, as well as operational and economic factors, such as the impact of the EU Emission Trading System (ETS) and FuelEU Maritime. Using system simulation, key vessel performance parameters such as energy consumption, emissions performance, and the financial impact of emissions will be evaluated in various operational and future decarbonization scenarios. The findings of this study will contribute to a better understanding of the key advantages that hybrid electric propulsion systems can offer in meeting increasingly stringent environmental requirements over the vessel's lifetime. The results will provide valuable insights for decision-makers in the maritime industry, aiding them in making informed choices regarding propulsion system selection to secure future-proof and sustainable assets.
