Special Issue Information

Dear Colleagues,

Maritime transport is hugely important in global trade, comprising more than 90% of trade if measured in cargo miles. However, it also contributes to global greenhouse gas emissions. As such, maritime transport carries a huge responsibility to save energy and cut emissions. It is obvious that it is—and probably always will be—challenging for maritime transport to fulfill the increasingly stringent environmental rules and goals imposed by IMO and regional governments, especially with the ever growing demand for transport.

This Special Issue will combine studies and results not only from naval architecture and logistics, but various other fields of research, regarding how maritime transport can become more energy efficient and environmentally friendly by reducing global emissions. Topics may include (but are not limited to) ship design and operation, alternative propulsion, renewable energies, engine design and optimization (combustion, electric, etc.), and maritime transport logistics. We look forward to receiving papers on theoretical and practical studies, holistic (and cross disciplinary) approaches, as well as detailed design optimizations, which will help to reduce the environmental impact of maritime transport.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

There exists no single optimal way for transporting hydrogen and other hydrogen carriers from one port to the other globally. Its delivery depends on several factors such as the quantity, distance, economics, and the availability of the required infrastructure for its transportation. Europe has a strategy to invest in the production of green hydrogen in Africa to meet its needs. This study assessed the economic viability of shipping liquefied hydrogen (LH2) and hydrogen carriers to Germany from six African countries that have been identified as countries with great potential in the production of hydrogen. The results obtained suggest that the shipping of LH2 to Europe (Germany) will cost between 0.47 and 1.55 USD/kg H2 depending on the distance of travel for the ship. Similarly, the transportation of hydrogen carriers could range from 0.19 to 0.55 USD/kg H2 for ammonia, 0.25 to 0.77 USD/kg H2 for LNG, 0.24 to 0.73 USD/kg H2 for methanol, and 0.43 to 1.28 USD/kg H2 for liquid organic hydrogen carriers (LOHCs). Ammonia was found to be the ideal hydrogen carrier since it recorded the least transportation cost. A sensitivity analysis conducted indicates that an increase in the economic life by 5 years could averagely decrease the cost of LNG by some 13.9%, NH3 by 13.2%, methanol by 7.9%, LOHC by 8.03%, and LH2 by 12.41% under a constant distance of 6470 nautical miles. The study concludes with a suggestion that if both foreign and local participation in the development of the hydrogen market is increased in Africa, the continent could supply LH2 and other hydrogen carriers to Europe at a cheaper price using clean fuel.
