Special Issue Information

Dear Colleagues,

The aim of this proposed Special Issue is to collect worldwide contributions from experts in the fields of hydrogen production and storage, and especially the chemical reactions involved in these fields. The following areas/sections will be covered by the call for original papers:

  • Alternative hydrogen production (electrolysis, solar-driven water splitting, bio-hydrogen, bio-gasification, hydrogen from biomass, etc.);
  • Hydrogen storage in solid materials;
  • Hydrogen storage in organic liquid carriers (LOHC)—hydrogenation/dehydrogenation cycle;
  • Power-to-hydrogen processes.

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. Reactions 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 1000 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.

The chemical-looping reforming (CLR) of methane for hydrogen production employs a solid oxygen carrier (OC) and combines endothermic and exothermic stages, allowing for potential autothermal operation. This study conducted a thermodynamic analysis using Gibbs free energy minimization and energy balances to assess the behavior of WO3, MnWO4, and NiWO4 as OCs in the CLR process. The effects of CH4:OC ratios and reactor temperatures on equilibrium composition and the energy performance were examined. The results demonstrated that elevated reduction temperatures promote OC conversion and the formation of more reduced solid products. Molar ratios above stoichiometric prevent carbon formation, whereas stoichiometric ratios result in higher H2 yield, achieving 98% at 1000 °C. However, these conditions do not support autothermal operation, which requires CH4:OC molar ratios above stoichiometric. Additionally, lower oxidation temperatures are preferred regardless of the OC, due to the lower heat needed to preheat the air, which has a greater effect on the net heat. For the reduction temperature, its effect depends on the type of OC analyzed. The maximum H2 yield obtained under autothermal operation was 88% for the three OCs, at 875 °C for MnWO4 and 775 °C for both WO3 and NiWO4. Full article
