Special Issue Information
Dear Colleagues,
Hydrogen storage will be a cornerstone technology for energy utilization in the 21st century once all aspects of a hydrogen economy come together. Hydrogen is stored for energy use with a device to provide power, but its storage can be detrimental to nuclear reactors’ structural materials or in hydrogen containers due to causing embrittlement. Advances have been made in the discovery, synthesis, and characterization of functional materials that can be used in sustainable infrastructure, including hydrogen production, storage, and delivery. To reduce hydrogen isotope ingress, a better understanding of hydrogen diffusivity, solubility, and permeability is important to reduce embrittlement in structural materials and the leakage of tritium into the reactor coolant. Many material properties impact hydrogen transport mechanisms, including material phase composition, impurities, grain boundaries, crystal orientation, trapping, defects, and dislocations. Hydrogen isotopes can easily permeate structural materials; thus, it is crucial to apply tritium permeation barriers (TRBs) in nuclear reactors to prevent ingress. Hydrogen barriers and accident-tolerant fuel (ATF) cladding materials are crucial to enable safe energy solutions in support of a hydrogen infrastructure and to ensure the safety of nuclear reactors such as fusion reactors, the development of future Gen IV nuclear reactors, as well as the containment of spent fuel. We invite both applied and fundamental research topics, including computational screening as well as theory and experiments to select hydrogen storage materials or advanced barrier materials.

Manuscript Submission Information
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. Molecules 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 2700 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.
