Engineering the Global Hydrogen Transition: Materials, Processes, Infrastructure, and Deployment

Dear Colleagues,

Hydrogen is increasingly recognised as a critical enabler of global decarbonisation, with applications spanning energy storage, industrial feedstock, transport, and power generation. Yet the transition from laboratory demonstrations to large-scale, economically viable deployment remains incomplete. While technological innovation continues at a rapid pace, the gap between research advances and practical implementation reflects fundamental engineering challenges that extend across materials, processes, infrastructure, and systems integration.

This Special Issue addresses that persistent gap by adopting an integrated engineering perspective on the hydrogen transition. Rather than viewing hydrogen technologies in isolation, we recognise that successful deployment requires coherent advancement across the full value chain—from production and storage through transport, safety, utilisation, and end-of-life management. The Special Issue explicitly seeks contributions that identify and resolve the specific engineering barriers currently constraining hydrogen realisation.

We welcome original research and critical reviews across four interconnected domains: production pathways that integrate with renewable energy and carbon capture, including novel technologies with demonstrated pathways to commercial scale-up; storage and transport systems that address infrastructure readiness, safety engineering, and the retrofitting of existing energy networks; system-level analysis—modelling, optimisation, techno-economic and life cycle assessment—that connects technological advances to deployable solutions; and interdisciplinary studies that bridge materials innovation, process engineering, infrastructure design, and deployment practice.

We particularly value submissions that explicitly address the research-to-deployment transition: identifying specific bottlenecks, proposing engineering solutions grounded in real-world constraints, and demonstrating how laboratory findings translate into practical hydrogen system implementation. By integrating diverse perspectives on hydrogen engineering across the full value chain, this Special Issue contributes to advancing how hydrogen technologies can be developed, integrated, and deployed effectively to support net-zero transition objectives.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Hydrogen is an international peer-reviewed open access quarterly 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 1200 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.
