Hydrogen Transport in Nuclear Energy Systems

Dear Colleagues,

Nuclear energy plays a critical role in the global transition toward low-carbon and sustainable energy systems. Within nuclear energy systems, hydrogen transport phenomena arise in a wide range of contexts, including proton-induced hydrogen generation and migration in accelerator-driven neutron sources, hydrogen and hydrogen isotope (H/D/T) transport in fusion reactor materials under high-temperature and -irradiation environments, and hydrogen generation, accumulation, and transport during spent nuclear fuel reprocessing and associated chemical processes, hydrogen and tritium migration in structural materials, nuclear-assisted hydrogen production processes, and hybrid nuclear–hydrogen energy systems. Understanding and controlling hydrogen transport is therefore essential for improving system efficiency, safety, reliability, and long-term performance.

This Special Issue aims to present and disseminate the most recent scientific and technological advances related to hydrogen transport in nuclear energy systems, covering fundamental transport mechanisms, modeling and simulation, experimental characterization, and system-level applications. Emphasis is placed on interdisciplinary studies that link materials science, thermal–fluid transport, nuclear engineering, and energy system analysis, in line with the scope of Energies, which focuses on energy generation, conversion, transport, utilization, and system integration.

Topics of interest for publication include, but are not limited to, the following:

• Hydrogen and hydrogen isotope transport and diffusion in nuclear energy systems and reactor components;
• Hydrogen-related degradation phenomena affecting nuclear reactor performance and reliability;
• Proton-induced hydrogen generation, diffusion and transport in accelerator-driven nuclear systems;
• Hydrogen and tritium behavior in fusion reactors and associated energy systems;
• Hydrogen generation, accumulation, and safety issues in spent fuel reprocessing;
• Experimental characterization and multiphysics modeling and simulation for hydrogen transport in nuclear systems;
• Integration of nuclear energy with hydrogen infrastructures and hybrid energy systems.

This Special Issue welcomes original research articles and reviews that contribute new insights into hydrogen transport phenomena and support the development of advanced nuclear energy systems for a clean and sustainable energy future.

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.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 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.
