Special Issue Information
Dear Colleagues,
Addressing climate change requires deep and rapid reductions in atmospheric carbon dioxide, making carbon capture and storage (CCS) an indispensable component of global decarbonization strategies. Among CCS pathways, geologic CO2 sequestration offers the most advanced and scalable solution, utilizing subsurface formations such as depleted oil and gas reservoirs, deep saline aquifers, and unmineable coal seams for permanent CO2 storage. In recent years, the field has expanded from conventional onshore operations to include offshore CO2 sequestration, hydrate-based CO2 storage, and integration with enhanced oil recovery (CCUS-EOR), each presenting unique opportunities and technical challenges. Advances in subsurface characterization, multiphase flow modelling, geomechanics, and geochemistry have significantly improved our ability to predict storage capacity and long-term containment integrity. Simultaneously, the development of reliable, cost-effective monitoring techniques has become critical for verifying storage permanence, ensuring environmental safety, and building public and regulatory confidence. As demonstration projects scale toward commercial deployment, the need for cross-disciplinary innovation—spanning reservoir engineering, materials science, geophysics, and environmental monitoring—has never been greater.
This Special Issue aims to present and disseminate the most recent advances related to the fundamental science, engineering practice, and field implementation of geologic CO2 sequestration across diverse geological settings and operational contexts. Topics of interest for publication include, but are not limited to, the following:
- Site characterization and screening methodologies for CO2 storage reservoirs;
- Offshore CO2 sequestration;
- Hydrate-based CO2 sequestration: thermodynamics, kinetics, and formation stability;
- CCUS-EOR: synergistic CO2 storage and enhanced hydrocarbon recovery;
- Integrated modelling and machine learning applications for storage forecasting;
- Risk assessment, leakage scenarios and advanced monitoring technologies;
- Life-cycle assessment and techno-economic analysis of sequestration projects;
- Multiscale multiphase flow and transport processes in porous media.

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-anonymized 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.
