Sustainable Hydrogen Technologies and Their Value Chains

Dear Colleagues,

Hydrogen gas is a promising energy carrier and an enabler in achieving the net zero decarbonization goals established in many countries around the world. This Special Issue of Processes focuses on various aspects the hydrogen value chain, including hydrogen production technologies, transport, storage, distribution, refueling infrastructures, and end use (both industrial and domestic). The suggested topics for this Special Issue include, but are not limited to, the following:

(1) Environmental life cycle assessment (e-LCA) of hydrogen value chains.

(2) Assessment methods of social life cycle assessment (s-LCA) of hydrogen value chains.

(3) Green hydrogen production from renewable sources (solar PV and wind turbines) integrated with water electrolysis technologies.

(4) Valorization of waste biomass to greener and sustainable hydrogen production in support of circular economy.

(5) Manufacturing of water electrolyzers for hydrogen production.

(6) Hydrogen carrier chemicals such as conventional and green ammonia gas.

(7) Hydrogen storage materials.

(8) Use of hydrogen in road transport (light-weight fuel cell-powered electric vehicles, trucks, and trailers) and electrified aircraft (hybrid-electric and all-electric).

(9) Hydrogen safety codes and standards.

(10) Critical reviews of research related to the hydrogen value chain.

(11) Hydrogen production integrated with carbon capture, utilization, and storage (CCUS).

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. Processes 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.
