Special Issue Information

Dear Colleagues,

The special issue on "Maritime Alternative Fuel and Sustainability" delves into the critical intersection of maritime transportation, alternative fuels, and environmental sustainability. Maritime transportation plays a pivotal role in global trade, but its reliance on conventional fossil fuels has significant environmental implications, including air and water pollution, greenhouse gas emissions, and climate change. This special issue aims to explore innovative solutions and strategies that promote the adoption of alternative fuels in the maritime industry, while concurrently addressing sustainability challenges.

Contributions to this special issue cover a wide range of topics, including but not limited to:

  1. Examination of alternative fuel options for maritime vessels, such as liquefied natural gas (LNG), hydrogen, biofuels, and electric propulsion systems.
  2. Analysis of the environmental impacts and benefits associated with the adoption of alternative fuels in maritime transportation, analysing their potential to mitigate air and water pollution, reduce greenhouse gas emissions, and combat climate change.
  3. Assessment of policy frameworks, regulations, and incentives aimed at promoting the use of alternative fuels and enhancing sustainability in the maritime sector.
  4. Evaluation of challenges, barriers, and opportunities for the widespread deployment of alternative fuels in maritime shipping, including infrastructure development, technology readiness, and economic considerations.
  5. Innovations in Waste Management. This special issue also highlights advancements in waste management practices within the maritime sector, including the reduction, recycling, and responsible disposal of waste materials generated during maritime operations.
  6. Integration of Alternative Fuels and Waste Management, exploring the synergies between alternative fuels and waste management, identifying opportunities for integration and optimization. For instance, research may focus on biofuel production from waste materials or the utilization of waste-derived resources in maritime operations.

By bringing together diverse perspectives from researchers, policymakers, industry stakeholders, and practitioners, this special issue aims to advance our understanding of the complex issues surrounding maritime alternative fuels and sustainability. Ultimately, the insights and findings presented in this special issue seek to inform decision-making processes, inspire innovation, and catalyze positive change towards a more sustainable future for maritime transportation.

This article considers the issues of ensuring operational performance and environmental sustainability of marine diesel engines by using biodiesel fuel. This research was conducted on 5S60ME-C8 MAN-B&W Diesel Group and 6DL-16 Daihatsu Diesel marine diesel engines, which are operated using RMG380 petroleum fuel and B10 and B30 biodiesel fuels. The efficiency of biofuel usage was assessed based on environmental (reduced nitrogen oxide concentration in exhaust gases) and economic (increased specific effective fuel consumption) criteria. It was found that the use of B10 and B30 biofuels provides a reduction in nitrogen oxide concentration in exhaust gases by 14.71–25.13% but at the same time increases specific effective fuel consumption by 1.55–6.01%. Optimum fuel injection advance angles were determined that ensure the best thermal energy, economic and environmental performance of diesel engines. The optimum angle of biofuel supply advance is determined experimentally and should correspond to the limits recommended by the diesel engine operating instructions. It has been proven experimentally that the use of biofuel increases the environmental sustainability of marine diesel engines by 13.75–29.42%. It increases the diesel engines environmental safety in case of emergency situations as well as accidental and short-term emissions of exhaust gases with an increased content of nitrogen oxides into the atmosphere phenomena that are possible in starting modes of diesel engine operation as well as in modes of sudden load changes. It is the increase in the environmental friendliness of marine diesel engines in the case of using biofuel that is the most positive criterion and contributes to the intensity of biofuel use in power plants of sea vessels.

This study proposes a feasible solution for boil-off gas (BOG) treatment to facilitate NH3 fuel use by ocean-going ships, which is currently considered an alternative fuel for ships. Two systems were designed and analyzed for BOG in IMO Type-A NH3 fuel storage tanks for 14,000 TEU container ships. First, BOG lost inside the storage tank minimized economic losses through the onboard re-liquefaction system. The total energy consumed by the system to process NH3 gas generated in the fuel tank at 232.4 kg/h was 51.9 kW, and the specific energy consumption (SEC) was 0.223 kWh/kg. Second, NH3 was supplied to the direct Low-Pressure Selective Catalytic Reduction (LP-SCR) system to treat marine pollutants generated by combustion engines. The feasible design point was determined by calculating the NH3 feed flow rate using three methodologies. The energy consumed by the direct LP-SCR system was 3.89 and 2.39 kW, and the SEC was 0.0144 at 0.0167 kWh/kg at 100% and 25% load, respectively. The feasibility was indicated via economic analysis. Depending on the life cycle cost, the competitiveness of the re-liquefaction system depends on the price of NH3, where a higher price yields a more economical solution. In conclusion, the direct LP-SCR system has a low overall cost because of its low energy consumption when supplying NH3 and its reduced amount of core equipment. Full article
