Al Yafiee et al. (2024): Direct air capture (DAC) vs. Direct ocean capture (DOC)–A perspective on scale-up demonstrations and environmental relevance to sustain decarbonization

Omnya Al Yafiee, Fatima Mumta, Priyanka Kumari, Georgios N. Karanikolos, Alessandro Decarlis, Ludovic F. Dumée IN: Chemical Engineering Journal, 497, https://doi.org/10.1016/j.cej.2024.154421

This paper critically discusses the status, challenges, and scalability of direct air capture (DAC) and direct ocean capture (DOC) at pilot or industrial scale. Key challenges include capital and operational costs, energy demands, and integrating green energy sources to reduce environmental impact. The review emphasizes on techno-economical benchmarking analyses to evaluate feasibility for large-scale deployment and their effectiveness in mitigating CO2 emissions and acting as tools towards delocalized CO2 production.

Salah et al. (2024): A Case Study of a Nature-Based Approach to Carbon Sequestration in Aquatic Habitats as a Strategy to Mitigate Climate Change along the Egyptian Northern Lakes

Aya Emam Salah, Elham Mahmoud Ali, Tarek Ahmed Temraz, IN: Advances in Environmental and Life Sciences, 2024, https://doi.org/10.21608/aels.2024.283493.1051

This study has shifted focus to natural methods for curbing emissions and protecting the environment, leading to the adoption of nature-based solutions, including carbon sequestration in water, sediment, and aquatic flora. The study aimes to evaluate and compare carbon sequestration rates in water and sediment samples from four northern Egyptian lakes, examining the carbon sequestration capacities of these aquatic habitats in planted and unplanted areas.

Abobakr Sori, Jafarsadegh Moghaddas, Hasan Abedpour, IN: Sci, 2024, https://doi.org/10.1002/ghg.2295

This review article aims to provide a comprehensive overview of the current state of research and development in the field of geological carbon dioxide (CO2) sequestration. The authors systematically examined a wide range of recent literature, focusing on advancements in numerical simulations, experimental studies, risk assessments, and monitoring techniques related to CO2 sequestration. Literature was selected based on relevance, recency, and contribution to the understanding of key challenges and solutions in CO2 storage, with sources spanning peer-reviewed journals, conference proceedings, and significant technical reports.

Liu et al. (2024): Investigating CO2 sequestration properties of biochar shotcrete

Guoming Liu, Lu Liu, Huamou Liu, Huiying Zheng IN: Construction and Building Materials, 443, https://doi.org/10.1016/j.conbuildmat.2024.137779 

This study investigated the effect of different biochar content on shotcrete under various curing conditions (carbonation, normal and low temperature). Flowability, compressive strength, splitting strength and microstructure of sprayed biochar shotcrete were conducted. Combined carbonation depth, thermogravimetric, and X-ray diffraction (XRD) were used to analyze the carbon sequestration of the biochar sprayed concrete materials from both macro and microscopic perspectives. In addition, the effect of low temperature on the performance of biochar shotcrete was considered.

Barman et al. (2024): Synergizing sustainability: a critical review on harnessing agroforestry for biomass, carbon sequestration, and water-food-energy nexus

Anamika Barman, Suman Dutta, Anurag Bera, Priyanka Saha, Jyotirmay Roy, Malini Roy Choudhury, Mahadev Bera, Sumanta Das, IN: Energy, Ecology, Environment, 2024, https://doi.org/10.1007/s40974-024-00336-6

This systematic literature review provides a comprehensive overview of research spanning 24 years, elucidating the role of agroforestry in mitigating climate change impacts, enhancing biomass provision, carbon sequestration, and optimizing the water-food-energy nexus. Various forms of agroforestry systems exhibit differing capacities to supply biomass and sequester carbon.

Nature – Wijaya et al. (2024): Basin-scale study of CO2 storage in stacked sequence of geological formations

Nur Wijaya, David Morgan, Derek Vikara, Timothy Grant, Guoxiang Liu IN: scientific reports, 14, https://doi.org/10.1038/s41598-024-66272-x

Commercial scale decarbonization through carbon capture and storage may likely involve many CO2 storage projects located in close proximity. The close proximity could raise concerns over caprock integrity associated with reservoir pressure buildup and interference among adjacent projects. Commercial-scale injection will also require large prospective CO2 storage resource and high injectivity in the targeted storage formations. To accommodate the need for both large resource and high injectivity, project operators could consider injecting CO2 into a stacked sequence of formations. This analysis investigates the benefits of injecting CO2 into a vertically stacked sequence of saline formations, over injecting the same amount of CO2 into a single saline formation, in addressing these challenges.

Nature – Dale et al. (2024): Seafloor alkalinity enhancement as a carbon dioxide removal strategy in the Baltic Sea

Andrew W. Dale, Sonja Geilert, Isabel Diercks, Michael Fuhr, Mirjam Perner, Florian Scholz, Klaus Wallmann IN: Communications Earth & Environment, 5, https://doi.org/10.1038/s43247-024-01569-3

Ocean alkalinity enhancement by the artificial addition of carbonate minerals to the seafloor has been proposed as a method to sequester atmospheric CO2 and store it in the ocean as dissolved bicarbonate. Here, a reaction-transport model is used to scrutinize the efficacy of calcite addition and dissolution at a well-studied site in the southwestern Baltic Sea – a brackish coastal water body in northern Europe.

Kreuzburg et al. (2024): Unified Assessment framework for proposed methods of MarineCDR and interim knowledge Synthesis

Kreuzburg, M., Baatz, C., Bednarz, L., Böttcher, M., Merk, C., Morganti, T., Tank, L., Yao, W. B., Wehnert, H., Rehder, G. IN: ASMASYS, DOI 10.3289/CDRmare.37

In ASMASYS, one of the main goals is to establish a comprehensive assessment framework for marine carbon dioxide removal (mCDR) and marine carbon storage (mCS) options, serving as a foundational tool for evaluating various methods uniformly.
A standardized assessment process promotes transparency, accountability and public trust in mCDR/mCS initiatives and facilitates informed dialogue and stakeholder engagement. Overall, the creation of an assessment framework is critical to the responsible development and implementation of
mCDR and storage methods, balancing the potential benefits with the need to minimize environmental and social risks.

Fridahl et al. (2024): Potential and goal conflicts in reverse auction design for bioenergy with carbon capture and storage (BECCS)

Mathias Fridahl, Kenneth Möllersten, Liv Lundberg, Wilfried Rickels IN: Environmental Sciences Europe, 26, https://doi.org/10.1186/s12302-024-00971-0

Sweden seeks to lead the way in bringing Bioenergy with carbon capture and storage (BECCS) up to scale, introducing a EUR 3.6 billion reverse auction scheme to facilitate market entry of companies producing BECCS. The authors explore instrument design preferences among politicians, regulators, and prospective BECCS operators to identify trade-offs and explore feasible policy design. Based on 35 interviews with experts in the latent BECCS sector in Sweden, the authors identify under which circumstances prospective operators would be willing to place bids and discuss how actor preferences both align with and challenge auction theory.

Buck et al. (2024): Racial capitalism’s role in mitigation deterrence from carbon removal

Holly Jean Buck, Nils Markusson, Wim Carton IN: Environmental Science & Policy, 160, https://doi.org/10.1016/j.envsci.2024.103865

Two major sociopolitical challenges loom over the development of carbon removal. One is mitigation deterrence: that research and deployment of carbon removal could delay mitigation efforts. The other is environmental and climate justice — in particular that carbon removal will be developed in ways that further environmental racism, e.g. for the benefit of interests and groups in the global North while harming overburdened communities of color. A variety of policy measures have been proposed to deal with these challenges, from developing separate targets for emissions and removals to social safeguarding principles and standards. Here, the authors describe how racial capitalism sets up mitigation deterrence, and how mitigation deterrence in turn goes on to perpetuate racial capitalism.
