Special Issue Information

Dear Colleagues,

Maritime transport is one of the largest greenhouse gas-emitting sectors in the global economy, responsible for around 1 GtCO2eq every year. In recent years, the maritime industry has increasingly embraced decarbonization and sustainability strategies, promoting the analysis and development of innovative solutions for green ship energy systems.

The transition from fossil fuels towards clean fuels represents a complex but essential goal to meet international emissions regulations and environmental targets.

The scientific community is devoting growing attention to these targets, focusing on the development of innovative propulsion technologies and the use of zero-carbon fuels. Hydrogen and hydrogen carriers could play a crucial role in reducing the environmental impact of shipping transportation. The use of these fuels, whether in conventional powertrain systems or advanced technologies such as fuel cells, can pave the way toward achieving sustainability goals. Additionally, hybrid solutions involving advanced battery technologies represent a promising path to further reduce emissions.

For all these systems, research efforts are aimed at ensuring their efficiency, safety, and reliability under real operational conditions.

The development of green ship energy involves multidisciplinary challenges, including the integration of hybrid propulsion systems and energy storage optimization. Furthermore, shipboard energy management systems must handle fluctuating power demands, variable environmental conditions, and ship-specific constraints through advanced control and optimization techniques.

This Special Issue invites the submission of papers on the topic of “Research and Development of Green Ship Energy”. This includes the optimal design of innovative propulsion systems for ships; thermodynamic modeling of propulsion systems fed with alternative fuels, the feasibility of the installation of these technologies according to ship arrangement constraints, and energy management strategies for green propulsion; simulation and experimental validation of innovative green energy technologies for maritime applications; and strategies for ensuring safety, robustness, and regulatory compliance in green ship energy systems.

Proton exchange membrane fuel cells (PEMFCs) have the advantages of high efficiency, a low operating temperature, and a pollution-free reaction. Therefore, PEMFCs have emerged as a viable clean energy solution for ships to reduce their carbon emissions. When PEMFCs operate in marine salt spray environments, foreign ions entering the cathodes of fuel cells with air can cause a decline in cell performance. In this study, the effects of the cation type (K+, Na+, Mg2+, and Ca2+) and concentration (0.25 M and 0.5 M) on cell performance in terms of the polarization curve were systematically investigated using a fuel cell test system. Cell performance degradation was observed due to the existence of cations. The influence of the four cations on cell performance followed the rule of Ca2+ > Mg2+ > Na+ > K+. Meanwhile, cell performance decreased with an increase in concentration. When the fuel cell was not contaminated, the voltage was 0.645 V at a current density of 1 A/cm2. When the concentration was 0.5 M, the corresponding voltages were 0.594 V, 0.583 V, 0.559 V, and 0.300 V, respectively. In addition, fuel cells contaminated by NaNO3 and NaCl were compared. Due to the existence of Cl, more severe performance degradation was observed when the fuel cells were contaminated by NaCl. Full article
