Offshore floating charging platform for all-electric vessels powered with renewable energy sources: techno-economic feasibility and emission reduction potential

Maritime transport carries over 80 % of the global trade and it is the most energy-efficient mode of transport. This mode of transport depends on fossil fuels, and it is a major generator of greenhouse gas (GHG) emissions. As emission standards push forward the energy transition of the maritime transport, the battery- powered electric ships are becoming the environmentally friendly, low-cost alternative solution that could decarbonize short-sea shipping. However, available batteries on the market and their characteristics make the electrification of the relatively long-distance international ferry routes more complex. This study is proposing a concept of mobile offshore charging platform for all-electric vessels to enhance electrification of long- distance maritime routes such as international ferry routes. The model considers replacement of a conventional diesel- powered ferry with a battery powered one and the implementation of a renewable-based floating charging platform. This platform can be used to decrease the required battery capacity of the battery-powered ships, due to the possibility of recharging batteries along the course of the voyage. The floating charging platform should act as a self-sufficient facility entirely relied on the electricity generated from the renewable energy sources (RES) and hybrid energy storage technologies. The proposed model is designed and verified using EnergyPLAN program. The study results show that implementation of the floating charging platform powered with hybrid offshore RES power system for charging battery-powered electric ferries (BEF) supports electrification of the short-sea shippining.
