Dear Colleagues,

We invite submission of original contributions to a Special Issue of the journal Energies on the recent developments in adsorption technology applied to hydrogen production and separation processes.

Nowadays hydrogen is gaining an ever-increasing importance in different sectors such as energy production, chemical industry, metallurgy and food processing. The development of high-efficiency processes for increasing the productivity and purity of H₂ is mandatory to foster the commercialization of advanced production technologies. Moreover, hydrogen production processes are fundamental in many decarbonization pathways including the generation of hydrogen-rich mixtures from fossil fuels, and contextually separating CO₂ (pre-combustion schemes). Adsorption represents a versatile and low-cost purification technology which can play a key-role in this framework.

Potential topics of this Special Issue include, but are not limited to:

• Adsorption of gaseous species (e.g. H₂S, H₂O, hydrocarbons) from gaseous streams (e.g. natural gas) in reforming processes;
• CO₂ adsorption from CO₂/H₂ mixtures in pre-combustion plants;
• Sorption-enhanced gasification or sorption-enhanced steam reforming of different feedstocks (e.g. fossil fuels or biomasses).

We welcome papers dealing with: i) experimental and theoretical adsorption studies on conventional (e.g. activated carbons, zeolites, CaO) and emerging sorbents (e.g. MOF, carbon nanotubes), where thermodynamic, kinetic, and thermo/fluid-dynamic analyses are performed; ii) relationships between sorbent properties and adsorption performances also predicted by means of machine learning (e.g. artificial neural network, ANN) and statistical thermodynamic methods; iii) reactor configuration (e.g. fixed, rotating and fluidized beds), sorbent regeneration and plant design (e.g. temperature, pressure, vacuum, electric swing adsorption) also with the integration of renewable energy sources; iv) process and techno-economic analysis also via commercial software and by implementing other methodologies (exergy analysis, exergoeconomic analysis, life cycle assessment).

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. Energies 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 2600 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.
