Book: Cost Analysis of Adsorption based Air Capture of CO2

Mona Muzammil, Muzammil Arshad, Muazzam Arshad; Edinburg: The University of Texas Rio Grande Valley. https://scholarworks.utrgv.edu/chem_fac/262.

The book opens with an introductory section that provides background regarding the need to reduce greenhouse gas emissions, an overview of carbon capture and storage (CCS) technologies, and a primer in the fundamentals of power generation. Chapters focus on key carbon capture technologies, including absorption, adsorption, and membrane-based systems, addressing their applications in both the power and non-power sectors.

Nature – Gidden et al. (2023): Aligning climate scenarios to emissions inventories shifts global benchmarks

Matthew J. Gidden, Thomas Gasser, Giacomo Grassi, Nicklas Forsell, Iris Janssens, William F. Lamb, Jan Minx, Zebedee Nicholls, Jan Steinhauser,Keywan Riahi IN: Nature; https://doi.org/10.1038/s41586-023-06724-y

National greenhouse gas inventories (NGHGIs) and scientific assessments of anthropogenic emissions follow different accounting conventions for land-based carbon fluxes resulting in a large difference in the present emission estimates, a gap that will evolve over time. Using state-of-the-art methodologies and a land carbon-cycle emulator, the authors align the Intergovernmental Panel on Climate Change (IPCC)-assessed mitigation pathways with the NGHGIs to make a comparison.

Stephenson & Allwood (2023): Technology to the rescue? Techno-scientific practices in the United Kingdom Net Zero Strategy and their role in locking in high energy decarbonisation pathways

Sam D. Stephenson, Julian M. Allwood IN: Energy Research & Social Science, 106, 103314, https://doi.org/10.1016/j.erss.2023.103314

This article reviews the characteristics of fifteen different UK Net Zero pathways (three government pathways and 12 additional pathways) and shows how the expectation of technology innovation and low-carbon energy abundance closes down the space potential pathways can occupy. In particular, the authors find that while conceptually different, the three government pathways display a high degree of similarity and that the majority of pathways rely on significant amounts of new clean energy and retain large residual emissions in 2050 which requires the deployment of significant new carbon dioxide removal technologies.

EU Parliament Approves The Carbon Removal Certification Framework And Net Zero Industry Act

by Petya Trendafilova, carbonherald.com, November 22, 2023

„The European Parliament voted on November 21st in a plenary session on long-awaited and debated climate policies. The Parliament has approved the Carbon Removal Certification Framework (CRCF) and the Net Zero Industry Act (NZIA), demonstrating its support for scaling up carbon dioxide removal (CDR) capacity in the EU – part of the bloc’s strategy in reaching climate neutrality by 2050.“

EU-Parlament fordert konsequentes Handeln in Dubai

Friederike Meier, fr.de (Frankfurter Rundschau), 21.11.2023, 16:43 Uhr

„Abgeordnete verlangen von EU-Vertretern klare Linie für Klimaschutz und Ausstieg aus fossilen Energieträgern.[…] Das EU-Parlament hat Kommission und Mitgliedsstaaten dazu aufgerufen, sich auf der Klimakonferenz in Dubai, die am 30. November beginnt, für ein ehrgeiziges Ergebnis einzusetzen. „Das Parlament ist der Meinung, dass die Union und die Mitgliedstaaten kein Ergebnis akzeptieren sollten, das Technologien zur Verringerung der Emissionen fossiler Brennstoffe im Energiesektor fördert“, heißt es in einer Resolution, die das Parlament am Dienstag verabschiedet hat.“

Ghaleigh et al. (2023): Beyond emissions trading to a negative carbon economy: A proposed Carbon Removal Obligation and its implementation

Navraj Singh Ghaleigh, Johannes Bednar, Justin Macinante, Michael Obersteiner IN: Climate Policy, https://www.research.ed.ac.uk/en/publications/beyond-emissions-trading-to-a-negative-carbon-economy-a-proposed-

A policy framework based on ‘carbon removal obligations’ (CROs) has been proposed by the authors to respond to concerns about the financial and fiscal viability, the lack of incentives for CDR uptake, as well as the physical and technological risks associated with any climate mitigation scenario that relies on large scale CDR. Here the authors propose an updated and improved CRO policy framework, consisting of two core elements: the ‘principal CRO mechanism’ obliges emitters of a tonne of CO2 to remove a tonne of CO2 at the time of maturity of the CRO. On top of this obligation, CRO holders need to pay a fee. This ‘CRO pricing instrument’, introduced in detail here, is used by regulators to steer the carbon emissions and removals pathways. The update suggests that markets for CDR under the CRO framework should operate independently from markets for emission reductions (ERs), such as emission trading schemes.

Song & Oh (2023): Market-pull, technology-push, and regulatory stringency determinants: All in need in firms‘ decisions for large-scale demonstration of direct air capture technologies

Yewon Song, Chaewoon Oh IN: Energy Research & Social Science, 106, 103339, https://doi.org/10.1016/j.erss.2023.103339

There is a lack of studies exploring firm-level behaviors in DACCS technologies. What behavioral determinants are responsible for firms undertaking large-scale demonstrations and deployment with innovative but uncertain DACCS technologies? Using an analytical framework that included market pull, technology push, and regulatory stringency determinants, a case study of the firm, Carbon Engineering, was conducted. The results reveal that the most important determinants are regulatory factors that are vital for mobilizing financial resources.
