Bouaboula et al. (2024): Comparative review of Direct air capture technologies: From technical, commercial, economic, and environmental aspects

Houssam Bouaboula, Jamal Chaouki, Youssef Belmabkhout, Abdelghafour Zaabout IN: Chemical Engineering Journal 484, 149411, https://doi.org/10.1016/j.cej.2024.149411

Direct air capture is set to play a crucial role in meeting climate change targets as most recent climate scenarios rely on its large-scale implementation. Nevertheless, despite this widespread consensus, DAC performance and impact have not been sufficiently investigated, which has resulted in hindering its wide-scale deployment for climate change mitigation initiatives. Here, we present a comparative review of different DAC technologies and examine their performance from a holistic perspective by considering different aspects, from technical, commercial, and economic to environmental.

Nokpho et al. (2024): Evaluating regeneration performance of amine functionalized solid sorbents for direct air CO2 capture using microwave

Pacharapol Nokpho, Paka-on Amornsin, Petpitcha Boonmatoon, Xiaolin Wang, Benjapon Chalermsinsuwan IN: Materials Today Sustainability 26, 100728, https://doi.org/10.1016/j.mtsust.2024.100728

CO2 capture by liquid amine has many drawbacks. These processes require significant energy to regenerate the solvents, releasing the captured CO2 for storage or utilization, which leads to increased operational costs and can diminish the overall efficiency of carbon capture systems. Recent research explores new promising techniques by CO2 capture using highly efficient solid sorbents. This study then focuses on enhancing a porous alumina material with potassium carbonate (K2CO3) and monoethanolamine to optimize CO2 capture capacity and regeneration performance.

Balasubramaniam (2024): Process-performance of solid sorbents for Direct Air Capture (DAC) of CO2 in optimized temperature-vacuum swing adsorption (TVSA) cycles

Bhubesh Murugappan Balasubramaniam, Phuc-Tien Thierry, Samuel Lethier, Veronique Pugnet, Philip Llewellyn, Arvind Rajendran IN: Chemical Engineering Journal 485, 149568, https://doi.org/10.1016/j.cej.2024.149568

The process performance of three amine-functionalized chemisorbents and two physisorbents was evaluated for direct air capture of CO2 in temperature-vacuum swing adsorption and steam-assisted temperature-vacuum swing adsorption cycles. The study showed that physisorbents, generally not studied for DAC, can be promising. Parametric studies revealed that the lack of multi-component thermodynamic and kinetic data impedes the objective evaluation of DAC processes.

Master thesis: Potential analysis of the integration of flexibly operated Direct Air Capture (DAC) plants in the heat and power system using the example of Hamburg

Moritz Rickert, Hamburg University of Applied Sciences, http://hdl.handle.net/20.500.12738/14920

For climate neutrality by 2045, Germany must compensate unavoidable residual greenhouse gas emissions by negative emission technologies such as direct air capture technology. This study explores the technical feasibility and economic viability of implementing flexibly operated DAC plants in Hamburg’s district heating system in 2045.

Ignatusha et al. (2024): Membrane Separation Technology in Direct Air Capture

Pavlo Ignatusha, Haiqing Lin, Noe Kapuscinsky, Ludmila Scoles, Weiguo Ma, Bussaraporn Patarachao, Naiying Du IN: Membranes 14(2), 30, https://doi.org/10.3390/membranes14020030

Current DAC technologies mainly consider sorbent-based systems; however, membrane technology can be considered a promising DAC approach since it provides several advantages, e.g., lower energy and operational costs, less environmental footprint, and more potential for small-scale ubiquitous installations. In this article, the ongoing research and DAC application attempts via membrane separation have been reviewed.

Master-thesis: Generalized Process Model for Solid Sorbent Direct Air Capture Contactors

Kshitij Mukeshbhai Patel, Arizona State University, https://keep.lib.asu.edu/items/190764

Extensive research and projections have suggested that DAC has tremendous potential to achieve global climate change mitigation goals. The feasibility of DAC is proven but work is required to bridge gaps in DAC research to make it affordable and scalable. Process modelling is an approach used to address these concerns. Current DAC research in system design and modelling is discrete and existing models have limited use cases. This thesis is focused on the development of a generalized process mass transfer model for the capture stage of solid sorbent DAC contactors.

Arwa and Schell (2024): Batteries or silos: Optimizing storage capacity in direct air capture plants to maximize renewable energy use

Erick O. Arwa, Kristen R. Schell IN: Applied Energy 355, 2024, 122345, https://doi.org/10.1016/j.apenergy.2023.122345

DAC is an energy intensive chemical process, whose designs are currently incompatible with intermittent renewable energy (RE) sources. This research develops a model to enable the flexible operation of DAC, to maximize RE usage. A new model of the chemical process flow of a liquid solvent DAC that includes silos to store CaCO3 and CaO is developed. A linear programming optimization model that minimizes energy costs while achieving the CO2 capture targets of the DAC plant is developed. Scenario analysis establishes the storage silo size and battery storage size needed to reduce renewable energy curtailment to zero for a given RE profile.
