Zeeshan et al. (2023): Direct air capture of CO2: from insights into the current and emerging approaches to future opportunities

Muhammad Zeeshan, Michelle K. Kidder, Emily Pentzer, Rachel B. Getman, Burcu Gurkan IN: Frontiers in Sustainability, 4, https://doi.org/10.3389/frsus.2023.1167713

The authors provide a mini review of the current research on the emerging liquid- and solid-based sorbent materials to capture CO2, summarize the existing challenges of DAC technologies, and suggest future research directions to accelerate the development of DAC systems. In particular, the desired properties for a breakthrough sorbent that efficiently captures CO2 from the air and releases it for sequestration are described.

Shu et al. (2023): Optimization of an electrochemical direct air capture process with decreased CO2 desorption pressure and addition of background electrolyte

Qingdian Shu, Ching Shing Sin, Michele Tedesco, Hubertus V.M. Hamelers, Philipp Kuntke IN: Chemical Engineering Journal 470, 144251, https://doi.org/10.1016/j.cej.2023.144251

An electrochemical process based on pH-swing has been proposed recently to regenerate spent alkaline absorbent from direct air capture (DAC). In this work, the authors experimentally investigated and theoretically simulated two optimization strategies to further reduce the energy consumption of such novel electrochemical process.

Kulkarni & Singh (2023): Direct CO2 capture from simulated and ambient air over silica-rich MIL-101(Cr)

Vaishnavi Kulkarni, Sanjay Kumar Singh IN: Reaction Chemistry & Engineering, https://doi.org/10.1039/D3RE00329A

Metal–organic frameworks (MOFs) are efficient adsorbents, but their application for low-concentration direct CO2 capture is mostly limited to amine-incorporating MOFs. Herein, the textural properties of the MOF [MIL-101(Cr)] are tuned by in situ incorporation of silica-rich rice husk ash (RHA) in MIL-101(Cr) to achieve enhanced CO2 capture from simulated and indoor ambient air over RHA-MIL-101(Cr).

Hoseinpoori et al. (2023): A comparative exergy-based assessment of direct air capture technologies

Sina Hoseinpoori, David Pallarès, Filip Johnsson, Henrik Thunman IN: Mitigation and Adaptation Strategies for Global Change, 28, 39,  https://doi.org/10.1007/s11027-023-10076-3

This work assesses the thermodynamic performances of different categories of DAC technologies, i.e., adsorption-based, absorption-based, ion exchange, and electrochemical. An exergy analysis is performed on the DAC processes in each category to identify hotspots for efficiency loss within the system.

Master-thesis: Institutional Analysis of Direct Air Capture in the context of Aviation Sustainability

Amogh Ravishankara, Delft University of Technology, August 2023

This thesis report presents an analysis of the suitability of adopting Direct Air Capture (DAC) for aviation sustainability, viewed through an institutional analysis lens using the Institutional Analysis and Development (IAD) framework. DAC is framed as a technology niche from the Multi-Level Perspective to get a descriptive understanding of the problem context and the interconnected parts in the larger picture of aviation sustainability innovations. Specific to DAC, multiple dimensions of DAC integration in the aviation sector, including technology, actors, and policy analysis are carried out. Employing the IAD framework, the underlying institutional arrangements, rules, and incentives influencing the adoption of DAC for carbon removal in the aviation industry are examined.

Fernández-Ríos et al. (2023): Carbon accounting of negative emissions technologies integrated in the life cycle of spirulina supplements

Ana Fernández-Ríos, Isabela Butnar, María Margallo, Jara Laso, Aiduan Borrion, Rubén Aldaco IN: Science of The Total Environment 890, 164362,https://doi.org/10.1016/j.scitotenv.2023.164362

Given the important contribution of the food sector to climate change, this study aims to investigate the role of two carbon capture and utilization (CCU) technologies in decarbonizing the production of Spirulina, an algae product commonly consumed for its nutritional characteristics. The proposed scenarios considered the replacement of synthetic food-grade CO2 in Arthrospira platensis cultivation (BAU scenario) with CO2 from beer fermentation (BRW) and CO2 from DACC (direct air carbon capture) (SDACC), representing two alternatives with great potential in the short and medium-long term, respectively.

Wie ein weltweites klimaneutrales und Wohlstand schaffendes Energiesystem aussehen kann

Franz Josef Radermacher, die-deutsche-wirtschaft.de, 09. September

„In einer Referenzlösung zeigt der Abschlussreport des Bundesministeriums für wirtschaftliche Zusammenarbeit und Entwicklung einen Weg auf, der es im Zeitraum 2050 – 2070 zehn Milliarden Menschen ermöglicht, ein Leben in Freiheit mit angemessenem Wohlstand in sozialer Balance, intakter Umwelt und stabilem Klimasystem zu führen. Von entscheidender Bedeutung ist dafür die Ausgestaltung des Energiesystems, da dieses von wesentlichem Einfluss auf Erfolg oder Misserfolg bei Klimaschutz und Wohlstandsaufbau ist. Sein Mitverfasser, Professor Dr. Dr. Dr. h.c. Franz Josef Radermacher, skizziert den Ansatz.“

Ghaffari et al. (2023): Sodium Hydroxide-Based CO2 Direct Air Capture for Soda Ash Production – Fundamentals for Process Engineering

Somayyeh Ghaffari, Maria F. Gutierrez, Andreas Seidel-Morgenstern, Heike Lorenz, Peter Schulze IN: Ind. Eng. Chem. Res. 2023, 62, 19, 7566–7579

This work introduces the principles and supplies the first key parameters for replacing the conventional ammonia-soda (Solvay) process with a new environmentally friendly and sustainable process. For this, the absorption of diluted CO2 (0.0153–1.2 vol %) in carbonated NaOH solutions was experimentally studied in a temperature range relevant for direct air capture (DAC) in the middle Europe (5–20 °C). A dynamic process model was formulated and solved based on the literature parameters.

Motlaghzadeh et al. (2023): Key uncertainties behind global projections of direct air capture deployment

Kasra Motlaghzadeh, Vanessa Schweizer, Neil Craik, Juan Moreno-Cruz IN: Applied Energy 348, 121485, https://doi.org/10.1016/j.apenergy.2023.121485

This study provides a comprehensive review of scenarios from the Intergovernmental Panel on Climate Change Sixth Assessment Report and peer-reviewed studies focusing on direct air capture as a mitigation strategy. The review identifies several key factors contributing to uncertainty in direct air capture projections, including prolonged fossil fuel use, diversity of carbon removal methods, future socio-economic conditions, intergenerational assumptions, deployment limitations, and technology costs. The study recommends conducting multi-model assessments of direct air capture scenarios due to the influence of various assumptions and model structures on projections.
