Special Issue Information

Dear Colleagues,

In recent years, most people have been experiencing first-hand consequences of climate change, such as frequent high-temperature records, unprecedented forest fires, accelerated ice melting, changing rain pattern, sea level rises, etc. This calls for urgent measures to reduce anthropogenic CO2 emissions. In that regard, the IPCC has highlighted the importance of CO2 capture and sequestration (CCS) in the portfolio of measures to reach net zero by 2050. In the past five years or so, CCS is gaining momentum, and there has been a significant increase in large CCS projects in some jurisdictions. Yet, there is a need to further reduce the cost of CO2 capture either through new and optimized solvents and materials and/or through process optimization. Apart from CO2 capture from large point sources, direct air capture (DAC) aims to capture CO2 from the atmospherere and is a technology that has recently attracted considerable interest. DAC is relatively new and offers considerable opportunities for technological development. Of course, CO2 capture technologies are intimately linked to howcaptured CO2 is used, and whether it is stored permanently or utilized for the production of fuel, chemicals, or other materials.  

This Special Issue aims to present and disseminate the most recent advances related to CO2 capture, direct air capture, CO2 sequestration, and CO2 utilization.

Topics of interest for publication include, but are not limited to, the following:

  • The optimization of conventional CO2 capture processes;
  • Novel solvents for CO2 capture;
  • CO2 capture from hard-to-abate industries (e.g., cement and steel);
  • Direct air capture (DAC);
  • Sorbents for DAC;
  • Techno-economic assessment of CO2 and/or DAC technologies;
  • CO2 sequestration (e.g., sedimentary basins and mineralization);
  • CO2 utilization toward fuels, chemicals, and other materials;
  • Life cycle analysis.

Advancing the modeling of evaporation and salt precipitation is essential in CO2 storage processes in aquifers. OpenFOAM provides a platform for computational fluid dynamics (CFD) modeling with its open-source C++ object-oriented architecture that can especially be used in the development of fluid flow models in porous media. Some OpenFOAM packages have been developed in this area, and their codes are available for use. Despite this, the existing OpenFOAM literature does not include a model that incorporates multicomponent interactions in multi-phase flow systems, referred to as compositional modeling, at the Darcy scale. This existing gap is addressed in this paper, where a new simple model in OpenFOAM is introduced that aims to model the interaction of CO2 and H2O components in CO2 storage processes in aquifers at the Darcy scale. The model, named compositionalIGFoam, incorporates a compositional solver by extending the impesFoam solver of the porousMultiphaseFoam package, while assuming some simplifications, to account for CO2/water mutual dissolution, relevant to carbon capture and storage (CCS) processes in aquifers. The functionality of the compositionalIGFoam solver was assessed by showcasing its ability to reproduce the outcomes of existing examples. In addition to that, the process of gas injection into a water-saturated core sample was simulated using the developed model to mimic CO2 injection into aquifers. The CMG-GEM commercial compositional simulator was used to compare its results with the coreflood model of this study. Phenomenal agreement was achieved with the GEM model, showing only 1.8% and 0.4% error for both components. This confirms the accuracy and reliability of the developed model. In conclusion, this study enhances the state of the art in porous media modeling using OpenFOAM 10, providing a valuable tool for examining fluid interactions in subsurface environments, especially within the context of CCS processes.
