Carbon Capture, Utilization and Storage Technology

Dear Colleagues,

It is widely recognized that global warming is occurring due to increasing emission of “greenhouse gas”, mainly carbon dioxide (CO₂), along with high demand for energy. Methods of capturing CO₂ from major industrial sources, such as fossil fuel-burning power plants or cement and steel factories, are being developed. Depending on the purity, CO₂ extracted from exhaust gases can be either injected into subsurface geological formations (CCS) or utilized/reused in industrial processes. One option is the production of value-added chemicals/fuels (CCU). The captured high-concentration CO₂ stream can be reused and isolated permanently via enhanced oil recovery (EOR); enhanced coal bed methane (ECBM); enhanced geothermal system (EGS) processes; and impermanently in urea fertilizer, polymers, renewable methanol, and formic acid production. On the other hand, the dilute CO₂ flue gas can be utilized in concrete curing, mineral carbonation, ECBM, and algae cultivation. Although significant advances have been made, safety issues and issues of cost effectiveness currently hinder the future of CCS. For CCU, drawbacks such as extensive energy consumption for CO₂ desorption, low capture efficiency, and slow sorption kinetics still need to be addressed.

This Special Issue on “Carbon Capture, Utilization, and Storage Technology” seeks high-quality works focusing on the latest technical developments and scientific understanding dealing with current hurdles in CCUS technology. Topics include but are not limited to the following:

1. Studies in carbon dioxide capture, transport (both by pipelines and ships), and geological sequestration;
2. The development of technically, environmentally, and economically viable ways of utilizing CO₂: as a feedstock for industrial production; in concrete curing, and mineralization; in enhanced GS, OR, or ECBM; and to produce chemicals and fuels;
3. Life-cycle assessment (LCA) for CCUS technology.

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. Processes is an international peer-reviewed open access monthly 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 2400 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.
