Electrification of maritime transport through integration of battery-powered electric ships and renewable energy systems

Batteries are progressively emerging in the maritime transport as a promising alternative to replace conventional power systems. Integration of battery-powered electric ships and the increasing penetration of renewable energy sources in the power sector are gradually striving to decarbonize maritime transport. Various studies have shown that maritime transport has a relatively high potential for CO2 emissions reduction through utilization of battery-powered electric ships, due to shifting programmable consumption from fossil fuels to electricity. However, increased number of battery-powered electric ships could become a major energy load in isolated smart energy systems if the energy for battery recharging would come from mainly renewable energy sources. The objective of this research is to explore the opportunity batteries and their integration in ships offer in the framework of renewable-based isolated smart energy systems. A method for modelling supply of a particular battery-powered electric ferry is presented, whose batteries are recharged from excess energy produced by local renewable energy sources. In this study, the impact of electrification of a particular ferry line is assessed, considering the renewable-based isolated smart energy system, by using EnergyPLAN software. Case study results confirm that ship electrification can lead to significant reductions in operation costs and life-cycle emissions, especially with ferry lines with relatively lower installed capacity, overall distance and travel duration.
