Scaling carbon capture and carbon removals does not mean business-as-usual for the fossil fuel industry

by Leonardo Buizza, Energy Transition Commission, November 2023

„As COP28 draws near, increasing attention is being paid to a crucial topic: the future potential and role for carbon capture, utilisation and storage (CCUS), and carbon dioxide removals (CDR). This year has seen scandals bloom around carbon offsets, increasing talk of “net-zero barrels” of oil, and the rise of the idea that carbon capture will allow the fossil fuel industry to maintain business-as-usual. Opposing arguments have emerged that the potential of both CCUS and CDR is either incredibly limited, or near limitless. Given the link to fossil fuel use and emissions of carbon dioxide, this leads to a very wide, almost incredible range of scenarios for future demand for fossil fuels – as we’ve highlighted in the chart below.“

Asibor et al. (2023): A machine learning approach for country-level deployment of greenhouse gas removal technologies

Jude O. Asibor, Peter T. Clough, Seyed Ali Nabavi, Vasilije Manovic IN: International Journal of Greenhouse Gas Control, 130, 103995, https://doi.org/10.1016/j.ijggc.2023.103995

The suitability of countries to deploy five greenhouse gas removal technologies was investigated using hierarchical clustering machine learning. These technologies include forestation, enhanced weathering, direct air carbon capture and storage, bioenergy with carbon capture and storage and biochar. The use of this unsupervised machine learning model greatly minimises the likelihood of human bias in the assessment of GGR technology deployment potentials and instead takes a more holistic view based on the applied data. The modelling utilised inputs of bio-geophysical and techno-economic factors of 182 countries, with the model outputs highlighting the potential performance of these GGR methods.

Policy Brief: Wer mitreden will, sollte diese Begriffe kennen

CDRterra Policy Brief, November 2023

Was ist CDR und wo liegt der Unterschied zu CCS? Wie erreichen wir Treibhausgasneutralität? Und was sind überhaupt Restemissionen? Um in der Debatte um die CO2-Entnahme mitreden zu können, muss man viele komplizierte Begriffe und Sachverhalte kennen und verstehen. Der neue Policy Brief von der deutschen Forschungsmission CDRterra klärt über Kernkonzepte auf und macht politische Entscheidungstragende, Journalist:innen und weitere Interessierte fit für die Diskussion rund um das komplexe Thema Carbon Dioxide Removal.

Master-thesis: Resolution Without Revolution: Green Capitalism, Ecological Management, and the Carbon Dioxide Removal Industry in the United States

Jacob Daniel Ferrell, Lund University, http://lup.lub.lu.se/student-papers/record/9114297

This thesis thus attempts to grasp history as it flies. By employing a Marxist theoretical approach, including concepts like the real subsumption of nature and the spatiotemporal fix,the author draws a nuanced illustration of the political economy of carbon dioxide removal in the United States. By mapping the organizations and investment flows that constitute the US CDR industry, he show that the industry is both already substantial and less connected to fossil capital than one might think. Instead, the author found that tech and finance are the key capitalist economic sectors driving the US CDR industry through their purchases of high amounts of removals from suppliers and through investment spread throughout the industry.

Report: C2G – Impact and learning report

Carnegie Climate Governance Initiative; November 2023

For the past 7 years, the Carnegie Climate Governance Initiative (C2G) has been working to bring the need for more comprehensive governance around large-scale carbon dioxide removal (CDR) and solar radiation modification (SRM), to the attention of the international community. With the initiative’s work now completing at the end of 2023, this report shares some key insights from C2G’s journey, exploring its impacts, and sharing some of the important lessons learned along the way.

Liu et al. (2023): Solar geoengineering and carbon removal significantly lower economic climate damages

Aobo Liu, John C. Moore, Xiao Cheng, Yating Chen IN: One Earth, 6,10, https://doi.org/10.1016/j.oneear.2023.09.004

Here, the authors improve climate-induced economic impact assessment, without considering social and ecological damages, for 12 scenarios by assimilating projections from 48 climate models into the PAGE-ICE model. The sustainable development pathway, including considerable implicit carbon dioxide removal, cost-effectively mitigates climate change impacts, as can scenarios that combine politically pledged emissions reductions with moderate solar geoengineering (SAI-1.5). Additionally, they find that combining solar geoengineering with no mitigation (G6) or implementing delayed but stringent carbon dioxide removal (SSP5-3.4-OS) can respectively reduce end-of-century climate damages to one-half or a one-quarter of the baseline SSP5-8.5 scenario.

Parliament’s ENVI Committee renames CRCF and introduces vital clarifications to Certification Framework

press release, Bellona Europa, October 24, 2023

The Carbon Removals Certification Framework, spearheaded by MEP Lidia Pereira, has seen substantial improvements, offering clarity and essential safeguards. Activities like Carbon Farming, Carbon Storage in Products, and Carbon Removals are now distinctly defined. With a focus on the long-term storage of atmospheric or biogenic carbon, these changes have broadened the scope, creating a comprehensive carbon accounting Certification Mechanism.

Masindi et al. (2023): Wastewater Treatment for Carbon Dioxide Removal

Vhahangwele Masindi, Spyros Foteinis, Phil Renforth, Efthalia Chatzisymeon IN: ACS Omega, https://doi.org/10.1021/acsomega.3c04231

The wastewater treatment process itself could present an innovative carbon dioxide removal (CDR) approach. Here, the calcium (Ca)-rich effluent of a phosphorus (P) recovery system from municipal wastewater (P recovered as calcium phosphate) was used for CDR. The effluent was bubbled with concentrated CO2, leading to its mineralization, i.e., CO2 stored as stable carbonate minerals. The chemical and microstructural properties of the newly formed minerals were ascertained by using state-of-the-art analytical techniques. FTIR identified CO3 bonds and carbonate stretching, XRF and SEM-EDX measured a high Ca concentration, and SEM imaging showed that Ca is well distributed, suggesting homogeneous formation.

The Delivery of C2G’s Mission: A catalytic journey toward governance of large-scale CDR and SRM – perspectives from stakeholders

October 30, 2023, 10:00 AM – 12:00 PM EDT, hosted by Carnegie Climate Governance Initiative (C2G), hybrid

C2G’s purpose is to bring to governments’ attention the urgent need to address the governance of emerging climate-altering techniques, including carbon dioxide removal (CDR) and solar radiation modification (SRM). Following completion of its mission, C2G will close-down at the end of 2023. As part of our final activities, C2G is planning a hybrid event on 30 October to celebrate C2G’s 7 years of achievement and share lessons learned looking back at major challenges, advancements and milestones related to the governance of CDR and SRM, as well as to provide an opportunity to look ahead to all that has yet to be accomplished.

Webinar: Scrubbing the Skies – Potential Role of BBNJ Treaty in Ocean-Based CDR

November 7th, 7:00 pm – 8:00 pm CET, hosted by Institute for Carbon Removal Law and Policy

In September of this year, the Biodiversity Beyond National Jurisdiction (BBNJ) treaty under the United Nations Convention for the Law of the Sea was opened for signature. The treaty is slated to enter into force after sixty nations ratify it. Given the fact that many ocean-based carbon dioxide removal approaches will either be deployed in the open oceans, or could have impacts in these areas, the BBNJ may prove to a key regulatory framework for the emerging industry. In this webinar, two researchers focused on the interface of the BBNJ and ocean CDR will join Simon Nicholson, Co-Chair of the Institute for Carbon Removal Law & Policy, in a roundtable discussion of the BBNJ’s potential future role in regulating ocean CDR approaches, as well how the BBNJ will interface with other pertinent ocean regimes.
