Gas Hydrates

Dear Colleagues,

Gas hydrates or clathrate hydrates are ice-like compounds, formed when host water molecules come into contact with guest species (typically gases and/or some volatile liquid molecules) at prevailing pressure–temperature conditions and generate a crystalline lattice. Gas hydrate formation can cause serious problems during natural gas production and transmission by blocking natural gas pipelines and production facilities. On the other hand, evidence demonstrates that a tremendous amount of natural gas in the form of gas hydrate exists in marine- and permafrost-associated sediments. Therefore, NGH reservoirs could be a future source of energy and, in parallel, suitable sites for CO₂ sequestration if the technology of CO₂/CH₄ gas hydrate exchange can be developed. Gas hydrate formation can also have many positive applications, including but not limited to: hydrate-based CO₂ sequestration and vital component production; hydrate-based CO₂ capture; hydrate-based cooling systems; fire extinguishment using CO₂ hydrate; nuclear power plants using CO₂ hydrate; hydrate-based effluent/ heavy metal separation and desalination; concentration or preservation of food through gas hydrates; hydrate-based separation of close-boiling point compounds; hydrate-based gas storage; etc.

This Special Issue is devoted to various topics on gas hydrates, including but not limited to: natural gas hydrate reservoirs and natural gas hydrates in marine- and permafrost-associated sediments; gas hydrates and flow assurance; positive applications of gas hydrates; modeling and simulation of gas hydrate systems; thermodynamics; kinetics; nucleation of gas hydrates, thermo-physical and mechanical properties of gas hydrates; CFD frameworks of gas hydrates; etc.

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.
