Dear Colleagues,

As awareness of realistic emission mitigation options increases, the importance of carbon capture, utilization, and various storage concepts becomes obvious. Although underground storage is the most effective means of emissions reduction, it can be considered the last step in the CCUS chain Significant benefits can be achieved by using CO₂ before it is permanently stored, especially considering the rising CO₂ price. High capturing costs, dependent on the industry, facility type, and the chosen capturing technology, imply that further utilization of the captured CO₂ is highly desirable to justify the investments. Finding the best combination of capture technology and subsequent utilization option is a complex issue that requires information regarding the broader context, e.g., transport options, legal framework, market conditions, etc. This means that there is no one optimal solution for CO₂ mitigation, but many scenarios where the injection of different fluids underground can be considered, including energy storage in the form of compressed gas, heat, or hydrogen.

The SI aims to gather various potentially viable and feasible CO2 mitigation, i.e., carbon capture and utilization schemes that contribute to the environmental and financial sustainability of industries currently labelled as a “pollutant”.

Innovative solutions for maintaining the sustainability of traditional industries and related emerging industries through CO₂ utilization schemes are welcome. The contributors are encouraged to suggest recent technical developments, case studies, analyses, reviews, and assessments relevant to CO₂ utilization scenarios.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

Carbon capture options in various industries and related challenges, chemical and physical CCU, co-optimizing, and the LCA of CO₂ EOR/EGR/ECBM, enhanced geothermal systems with possible combinations of energy storage and permanent CO2 storage, the technological and economic potential of other CO₂ utilization options (CO₂ methanation, CO₂ to methanol, biofuels from algae, BECCS, carbonation – primarily in waste-to-energy plants, food freezing, beverages carbonation, and polymer production), and issues such as legal framework related to CO₂, national CO₂ markets, and public communication and acceptance.

We look forward to receiving your contributions.

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. Sustainability 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 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.
