Green and Low-Emission Hydrogen: Pathways to a Sustainable Future

Dear Colleagues,

The global imperative to achieve net-zero emissions is fueling an unprecedented energy transition. While renewables like solar and wind are decarbonizing the power sector, they alone cannot address the persistent carbon footprint of hard-to-abate industries such as heavy-duty transport, steelmaking, chemical production, and seasonal energy storage. At this pivotal time, green and low-emission hydrogen has emerged as the critical missing link in the clean energy puzzle.

This Special Issue, “Green and Low-Emission Hydrogen: Pathways to a Sustainable Future”, is dedicated to dissecting the promise and challenges of this versatile energy sector. We aim to spotlight the technological breakthroughs, economic paradigms, and systemic integration strategies that are accelerating hydrogen implementation to a tangible global commodity. A complex value chain is to be considered: from advanced electrolyzer technologies and other, low-emission hydrogen sources, to declining the levelized cost of hydrogen (LCOH) for safe and efficient storage, transportation, and innovative end-use applications.

By addressing the interdisciplinary nature of this transition, this Special Issue aims to serve as a foundational reference, charting the viable pathways to a sustainable, hydrogen-enabled future.

The scope of the Special Issue comprises, but is not limited to, the following topics:

• Advances in hydrogen production pathways; low-emission hydrogen and biohydrogen.
• Advances in materials and processes for hydrogen storage and transportation; hydrogen carriers.
• Advances in pure hydrogen transportation and co-transportation with natural gas: facilities testing and development, process control and sensors, and future development.
• Decision support methods for hydrogen system deployment.
• Techno-economic and life cycle analyses of integrated hydrogen systems and analyses of drivers and barriers to their implementation.
• Process safety aspects of hydrogen production, storage, transportation, and use.
• The social aspects and public acceptance of a hydrogen economy.
• The assessment and implementation of national and regional hydrogen strategies; the deployment and development of hydrogen valleys.

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. 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.
