Abstract
To mitigate greenhouse gas emissions resulting from the combustion of fossil fuels in
conventional transportation—including vehicles, ships, and aircraft—a wide range of
alternative energy sources have been explored, such as liquefied natural gas (LNG),
methanol, liquefied petroleum gas (LPG), biomass, solar energy, hydrogen, fuel cells,
and batteries. Among these, battery electric propulsion systems (BEPS) have emerged
as a particularly promising option, offering the potential for zero-emission operation
and scalability across various transport sectors.

This study investigates the modeling, validation, and application potential of Battery
Electric Propulsion Systems (BEPS) and their integration with internal combustion
engines in marine configurations. A detailed mathematical framework is developed
to describe the physical, economic, and emission-related behaviors of both battery-
based and ICE-driven systems. The models are validated against literature results
and applied to a case study involving a ferry operating in the Faroe Islands. Key focus
areas include the impact of time step sensitivity, emission penalties, and charging
strategies on system performance and cost. Additionally, the effect of vessel speed on
energy demand and lifecycle economics is assessed. The results highlight the trade-
offs between electrification levels, cost-effectiveness, and environmental performance,
offering insight into potencial full-electric configurations under real-world operating

Popular Abstract
The maritime sector accounts for about 3% of global CO₂ emissions, largely due to heavy fuel oils. Battery-Electric Propulsion Systems (BEPS) offer a promising low-emission alternative for short-sea shipping. A techno-economic study at Lund University shows that BEPS can be cost-competitive and reduce emissions, especially as electricity becomes cheaper and fuel costs rise. Choosing the right battery and charging strategy is key, and future battery technologies could further improve performance.
