Renewable Hydrogen and Hydrogen Carriers for the Maritime Sector

Dear Colleagues,

The maritime sector represents one of the most challenging industries to decarbonize due to its dependence on high-energy-density fuels and the long lifetimes of existing vessels. Renewable hydrogen and hydrogen-based carriers (such as ammonia, methanol and others) have emerged as promising solutions to enable sustainable maritime transport and reduce greenhouse gas emissions.

Recent advances in renewable hydrogen production, hydrogen carrier synthesis, on-board utilization technologies (such as fuel cells), and port infrastructure investments have laid a foundation for the development of clean maritime fuel value chains. However, several technical, economic, and political challenges remain. These include optimizing hydrogen and carrier production, ensuring safe and efficient transportation and on-board storage, enhancing on-board energy conversion systems, and aligning international standards and regulations to foster large-scale adoption.

This Special Issue invites original research papers that cover a wide range of topics for the decarbonization of the maritime sector using renewable hydrogen and hydrogen carriers. Authors are also encouraged to submit review papers that summarize the recent progress in these fields.

We look forward to receiving your contributions.

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 250 words) can be sent to the Editorial Office for assessment.

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. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.
