燃料电池和锂电池在拖轮动力中的对比与集成OA

Under the"dual carbon"strategic goals,energy transformation is imperative,and the application of fuel cell and lithium battery hybrid power systems in ship propulsion has become an important direction for future green and sustainable development.This paper analyzes the comparison of the characteristics of these two power technologies for tugboats with hybrid power systems.To evaluate the comprehensive economic benefits of hybrid propulsion systems,this study selected a specific port tug model and employed a full life-cycle economic model to conduct comparative analysis with a pure lithium-battery-powered vessel of the same type.The analysis focused on core metrics including total investment,total cost,and total profitability.The results show that the hybrid power system of fuel cells and lithium batteries can achieve the best economic indicators for tugboats.With the development of fuel cell technology and the gradual improvement of hydrogen fuel supply system,fuel cells will have broader application prospects in the field of ship propulsion.
