Gas Hydrates in Marine Environments

Dear Colleagues,

Natural gas hydrate has been considered as a potential clean energy resource for the future due to its large resource volume and high energy density with more than 97% identified at marine settings. Other types of gas hydrates (e.g. CO₂ hydrate, semi-clathrates) could play an important role in long-term carbon storage to achieve the world’s most urgent mission—carbon neutrality by 2050. Thus, the interactions between gas hydrate and environments comprise an extremely viral research topic, which is the key scope of this Special Issue. The geological phenomena of gas hydrate are intriguing and the technological applications of gas hydrate has gained ever-increasing research interests.

This Special Issue aims to solicit the most innovative studies covering chemical, physical, geological, geochemical, geomechanical, environmental, economic aspects of gas hydrates and hydrate-bearing sediments. In particular, experimental and numerical studies on the thermodynamics and kinetics of gas hydrate processes in relation to the marine environment are highly sought. Potential topics include energy recovery from CH₄ hydrate (including both novel production techniques and numerical/reservoir models), environmental impact and geohazards from CH₄ hydrate production and CH₄ seepage, hydrate-based CO₂ capture and separation, long-term CO₂ hydrate sequestration onshore and offshore, novel CO₂-CH₄ exchange method for energy recovery, hydrate inhibition technologies in offshore pipelines, deep sea oil and gas blowout with hydrate formation and transport, etc. The Special Issue welcomes both reviews and original research papers.

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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water 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.
