Advances in Sustainable Hydrogen Energy and Fuel Cell Research

Dear Colleagues,

Over the past century, the extensive use of fossil fuels such as coal, oil, and natural gas has driven rapid industrial development, but it has also resulted in unprecedented environmental pollution, global warming, sea-level rise, and a series of escalating crises. To address these challenges, a broad global consensus has emerged around carbon neutrality, highlighting the urgent need for clean alternative energy sources and advanced energy-conversion pathways. Hydrogen, featuring high energy density, diversified production routes, and zero carbon emissions at the point of use (producing water as the only by-product), is widely recognized as a highly promising clean energy carrier. Fuel cells, as a key technology for efficiently converting hydrogen into electricity and power, play a pivotal role in enabling the hydrogen economy. Nevertheless, before hydrogen can be utilized at scale, significant theoretical and engineering challenges remain across production, storage, transportation, utilization, safety, and system integration, calling for continued innovation and cross-disciplinary collaboration.

This Special Issue will invite advanced technologies, original theories, and trends in the field of hydrogen energy and fuel cells, including experimental research, numerical research, systematic research, review research, etc., to be peer-reviewed for publication. Topics suggested in this Special Issue include, but are not limited to, the following: water electrolysis for hydrogen production, novel hydrogen production technologies, hydrogen-based fuels, high-pressure hydrogen storage and transportation, liquid hydrogen storage and transportation, solid-state hydrogen storage and transportation, fuel cells, hydrogen-powered propulsion and mobility, hydrogen safety and standards/codes, and intelligent design and optimization of hydrogen energy systems.

We look forward to receiving your contributions.

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 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. 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.
