Techno-economic assessment of a PV/SC hybrid Power System Integrated into 2240 PCTC Ro-Ro Ship

Integrating solar PV energy into marine power system provides a new way to deal with the rapid growth of fossil fuels consumed by traditional ships in improving the energy efficiency and reducing the greenhouse-gas emissions. In this study, one practical PV/SC hybrid power system integrated into a 2240 pure car and truck carrier ro-ro ship is utilized as a case to carry out the techno-economic analysis. Taking into account the navigation route of the target ship, the amount of electricity generated by the PV/SC hybrid system is calculated based on the solar irradiation data of the seven port cities on the route. The analysis results show that (i) the levelized cost of energy of the PV/SC hybrid power system reduces to 0.53 USD/kWh from 3.89 USD/kWh over the life cycle; (ii) the discounted payback time of the PV/SC hybrid power system is 5.49 year. 1
