The overall process was designed to demystify the holistic environmental benefits and harms of 14 primary energy sources for electricity production in consideration of the national-specific cases of 33 countries. A series of comparative analyses between the diesel as the reference fuel and the battery-electric propulsions were conducted with 27 short-route ferries engaged in Scotland coastal areas. A key message obtained from the analysis results were that the impact of battery application was far from the zero-emission shipping in the lifecycle perspective. Moreover, the same vessels were found to yield completely different environmental performances, depending on how those countries produce electricity. In some Asian countries heavily relying on fossil-based power generation, the environmental impact of battery operation was estimated far greater than that of diesel operation in the UK. Case studies were, then, Is electric battery propulsion for ships truly the lifecycle energy solution for marine environmental protection as a whole? 2 scaled-up to about 5,500 marine vessels presently engaged in international voyages. In general, consistent results were found. Research findings distinctively demonstrated the misguidance of current maritime policies for encouraging battery-powered ships and identified that these shortcomings would stem from the limitations of current practices of maritime environmental assessment. Lastly, it strongly suggested to the marine industry and stakeholders that the environmental protection from shipping activities would be not only a matter of ships but also a matter of how the national power grid develops.

To demonstrate its excellence, the proposed method was applied to one of the most challenging topics in the marine industry. That was to tackle the fundamental doubt of whether solar-electric propulsion ships could truly be the future Live-life cycle assessment of the electric propulsion ship using solar PV

In this case, a 40 m short route ferry is converted to a solar-electric operating in the Strait of Messina. The powering configuration of the ship is modelled, and a simulation is run using MATLAB. Finally, after the results were found, the solar-electric ship’s powering costs and environmental impact using the Life Cycle Assessment method with the help of GaBi, were compared to a fully electric and a diesel alternative. GaBi is a very useful software to perform LCAs as it provides a very large database on various product’s emissions which can be modulated depending on their quantity. The results were encouraging as approximately 400,000 € were saved when using solar panels compared to only electricity and 500,000 € when comparing to diesel. Moreover, an observable reduction in the emissions in the solar-electric alternative. Remarkably, the electricity in the national grid produces a non-negligible impact on the environment. Therefore, any device which produces zero emissions but is powered by electricity coming from the national grid like an electric car is far from being emissions-free. On the other hand, the electricity coming from solar panels is close to being totally green and should all the electricity be coming from them if future advances on this technology are made, then the vehicle can be considered eco-friendly. The numerous advantages of solar panels in short route ferries observed in this research could lead to the replacement of the traditional oil powered ferried creating a huge positive impact on the environment. When looking at the future, some thought should be given the recycling of solar panels in order to stop our impact on the environment.

It was mainly focused on international and local efforts to reduce greenhouse gas (GHG) emissions from shipping activities while introducing new strategies, agreements, and regulations to meet the target on GHG reduction levels. It firstly reviewed the impact of the Clydebank Declaration made at 26 th UN Climate Change Conference in Glasgow, 2021. Then, the review was moved to UK and EU policies and activities. Findings from this research offer some insights into local governmental authorities and shipping companies in terms of how to respond to gradually stringent environmental regulations as well as their roles to make the shipping sector cleaner.

Regarding the various methodologies and technologies reviewed for this purpose, Life Cycle Cost Analysis (LCCA) has been used as an excellent tool to determine economic feasibility and sustainability and to present directions. However, insufficient commercial applications cause a conflict of opinion on which fuel is the key to decarbonisation. Many LCCA comparison studies about eco-friendly ship propulsion claim different results. In order to overcome this and discover the key factors that affect the overall comparative analysis and results in the maritime field, it is necessary to conduct the comparative analysis considering more diverse case ships, case routes, and various types that combine each system. This study aims to analyse which greener fuels are most economically beneficial for the shipping sector and prove the factors influencing different results in LCC...

To solve this problem, the government has enacted a policy to promote the development and distribution of environmental vessels. Electric propulsion systems and hybrid systems are suggested as alternatives. However, to study whether this hybrid system is environmentally friendly, a system for measuring the performance of conventional diesel-powered ships was developed and measured. A case study applying the battery hybrid system was analyzed through a Matlab/Simulink simulation, and the effect of reducing the carbon dioxide emissions by 7.6% was verified. In addition, comparing with a case where the load-sharing optimal control was introduced, we proved that the carbon dioxide reduction with the controller was 10.7%. By applying the results of this study to various countries with different fuel production processes through the LCA t...
