Abstract
Maritime transport accounts for 80% of global trade, but generates 2-3% of total global CO2 emissions. The IMO 2023 strategy targets a 40% reduction in carbon intensity and the adoption of 5-10% zero-emission energy by 2030. Previous research has shown that photovoltaic (PV) systems on Ro-Ro ferries can generate 334 MWh per year with an efficiency of 7.76%, but still experience energy intermittency limitations. This study addresses these limitations by integrating Thermal Energy Storage (TES) based on a ternary molten salt mixture to optimize overall energy utilization. The researchers tested ten ternary molten salt NaNO3-LiNO3-Na2SO4 (NLN) compositions to identify the optimal formula based on thermodynamic properties using Engineering Equation Solver (EES). The analysis results show that the NLN-5 composition (32.5%NaNO3 -65%LiNO3-2.5%Na2SO4) has the widest working point, with a melting point of 195.7˚C and a decomposition temperature of 846.3˚C. The integrated PV-TES system increased energy efficiency from 7.76% to 15.26% and annual electricity production from 334 MWh to 657 MWh. PV-TES technology significantly contributes to achieving the IMO 2030 target with a 15.26% contribution of renewable energy, while reducing CO2 emissions due to fuel savings. This study proves that an optimized molten salt TES system is an effective solution for decarbonizing the maritime sector.
