Special Issue Information

Dear Colleagues,

The growing urgency to mitigate the impacts of climate change has driven the development and adoption of technologies aimed at decarbonizing energy systems and industrial processes. This Special Issue brings together scientific studies and technical analyses focused on two strategic pillars of the energy transition: hydrogen energy—particularly low-carbon hydrogen—and Carbon Capture, Utilization and Storage (CCUS) technologies. Hydrogen is emerging as a promising energy vector due to its versatility, high energy density, and potential for integration across multiple sectors, from heavy industry to long-distance transport. Simultaneously, CCUS technologies are increasingly seen as essential tools for reducing emissions in carbon-intensive industries and fossil-based power generation, especially in the short to medium term.

This Issue will feature articles that explore the technical, economic, and regulatory aspects of these technologies, as well as case studies illustrating their practical implementation in different geographic contexts. It also seeks to discuss the synergies between hydrogen and CCUS, emphasizing integrated strategies aimed at achieving carbon neutrality in the coming decades. By bringing together contributions from researchers, industry professionals, and policymakers, this Special Issue seeks to foster informed and interdisciplinary dialogue on viable solutions for a cleaner, safer, and more sustainable energy future.

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. C is an international peer-reviewed open access quarterly 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 1600 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.

Direct-fired supercritical CO2 cycles are considered a promising way to reduce CO2 emissions in the energy sector. One of the key elements of such cycles is a combustor, in which natural gas is burned at supercritical pressures up to 300 atm in an O2/CO2 environment. Understanding the chemical combustion kinetics of C1–C4 alkanes, the main components of natural gas, in a supercritical CO2-diluted medium is important for designing such combustors. This article provides an overview of studies on the chemical kinetics of C1–C4 alkanes combustion in CO2 at ultra-high pressures. It has been established that with increasing pressure, regardless of the diluent, CH3O2 and HO2 chemistries start to significantly influence the combustion of alkanes, but at the moment this influence is not sufficiently understood. Influence of CO2 dilution on kinetics is mainly thermal, but the chemical effect is also significant. At the same time, the direct chemical effect of CO2 is more important for the laminar burning velocity, while the indirect third-body effect is more important for the ignition delay time. However, the available literature lacks experimental measurements of the laminar burning velocity in a CO2 environment at pressures above 70 atm, which limits the current understanding of chemical kinetics at supercritical pressures.
