Special Issue Information
Dear Colleagues,
Gas hydrates are crystalline solids that form through the contact of light hydrocarbon or sour gas species with water under high-pressure and low-temperature conditions. As the energy industry commonly operates at such conditions, hydrate formation across the breadth of upstream process conditions can rapidly result in serious restrictions for flow, including complete blockage under severe conditions. Hydrate formation leading to blockage has also been extensively documented in export natural gas pipelines, most commonly due to failed dew point sensors.
In both process streams, the energy industry and their research partners across academic and private sectors continue to invest significant effort in characterizing the phenomenology associated with severe hydrate blockage formation. This Special Issue targets new understanding around the kinetics of hydrate growth—at both an interfacial and macroscopic length-scale—alongside the mechanics of hydrate particle transportation in a multiphase environment. Importantly, the issue seeks to highlight those new phenomenological depictions of the complex processes that govern severe hydrate blockage formation.
While the deployment of thermodynamic hydrate inhibitors—commonly alcohols and glycols—remains the primary basis for blockage prevention, this Special Issue also seeks to explore new developments in low-dosage hydrate inhibitors that offer the possibility to eliminate continuous anti-freeze dosage. Of particular relevance in the upstream context, new insights into the structure–function relationships behind both hydrate anti-agglomerants and kinetic hydrate inhibitors are of critical interest for this Special Issue, alongside improvements in the performance characterization of these advanced chemical inhibitors.

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.
