CO₂-removal News

Wird Deutschland so klimaneutral?

Claudia Vallentin, ZEIT online, 15. September 2022, 11:11 Uhr

„CO₂ unter der Erde zu lagern, statt es in die Atmosphäre zu blasen, wäre gut fürs Klima. Norwegen will das in der Nordsee umsetzen, auch in Deutschland wäre das möglich. […] Carbon Capture and Storage, kurz CCS, heißt die Technik, mit der sich CO₂ tief unter der Erde speichern lässt. Nicht nur in Norwegen, auch in Deutschland ist das geologisch möglich und sogar getestet. Trotzdem stößt CCS im heimischen Untergrund auf Widerstand, dabei wird es schwierig, ohne die CO₂-Speicherung klimaneutral zu werden.“

Ocean Visions Summit 2023: Innovating Solutions at the Ocean-Climate Nexus

April 4-6, 2023, in Atlanta, Georgia

The next Ocean Visions Summit will be held from April 4-6, 2023, in Atlanta, Georgia. This will predominantly be an in-person event, but with a modified virtual component. Contributions to the Summit program can be made by applying to chair a session within one of the five tracks: 1) Ocean-Based Contributions to Global Decarbonization, 2) Ocean-Based Contributions to Carbon Dioxide Removal, 3) Ocean Ecosystem Regeneration, 4) Human Adaptation to a Changing Ocean, and 5) Building a Global Community of Solvers at the Ocean-Climate Nexus. Applications should be submitted by 9/30/2022, Ocean Visions will notify candidates by 10/21/2022.


Microalgae CDR Road Map Workshop

October 13 4:00 – 6:00 PM PDT (UTC-7) or October 20 8:00 – 10:00 AM PDT (UTC-7)

Ocean Visions is developing a new road map on microalgae cultivation for carbon sequestration and is seeking experts in relevant fields to support the process by identifying information gaps and first-order priorities. Building on an existing set of five ocean-based CDR road maps, the microalgae road map is intended to catalyze global engagement on research and development. We will hold two scoping workshops, one at a Europe-friendly time and one at an Asia/Australia-friendly time. You may nominate yourself or someone else to participate in the workshops.


Nature – Xu et al. (2022): Delayed use of bioenergy crops might threaten climate and food security

Siqing Xu, Rong Wang, Thomas Gasser, Philippe Ciais, Josep Peñuelas, Yves Balkanski, Olivier Boucher, Ivan A. Janssens, Jordi Sardans, James H. Clark, Junji Cao, Xiaofan Xing, Jianmin Chen, Lin Wang, Xu Tang, Renhe Zhang IN: Nature 609, 299–306 (2022).

The potential of mitigation actions to limit global warming within 2 °C might rely on the abundant supply of biomass for large-scale bioenergy with carbon capture and storage (BECCS) that is assumed to scale up markedly in the future. However, the detrimental effects of climate change on crop yields may reduce the capacity of BECCS and threaten food security, thus creating an unrecognized positive feedback loop on global warming. The authors quantified the strength of this feedback by implementing the responses of crop yields to increases in growing-season temperature, atmospheric CO2 concentration and intensity of nitrogen (N) fertilization in a compact Earth system model.


Qi & Dauvergne (2022): China and the global politics of nature-based solutions

Jianfeng Jeffrey Qi, Peter Dauvergne IN: Environmental Science & Policy 137,

This article explains how and why China has been promoting NbS in multilateral and domestic policy settings. By analyzing the content of English- and Chinese-language policy briefings, diplomatic remarks, and government documents from 2019 to mid-2021, it reveals that China’s NbS goals and actions differ significantly in domestic and international settings.


Research Associate in Sorbent-based Direct Air Capture (DAC) Technologies

Deadline: October 4

Research Centre for Carbon Solutions (RCCS), Heriot-Watt University, Edinburgh: „we are seeking a creative and motivated post-doctoral researcher to work as part of our international and multidisciplinary USorb-DAC (“Unlocking the scalable potential of sorbent-based DAC technologies”) team and with expertise to support our research activities in the project. The project’s aim is to discover adsorbents that can drastically reduce DAC’s energy intensity and cost so that DAC can scale rapidly and contribute to fighting climate change.The appointment will be at Research Associate level, Grade 7, Salary: £34,308 – £42,155, fixed term opportunity for 12 months, with possibility of an extension. „


Nature – Diederichsen et al. (2022): Electrochemical methods for carbon dioxide separations

Kyle M. Diederichsen, Rezvan Sharifian, Jin Soo Kang, Yayuan Liu, Seoni Kim, Betar M. Gallant, David Vermaas, T. Alan Hatton IN: Nature Reviews Methods Primers 2, 68 (2022).

The authors provide an overview of the experimentation and analysis needed for the study of electrochemical methods for CO2 separation, including a discussion of the considerations necessary for targeting the application of such techniques. The article focuses on ambient temperature techniques such as pH swing and direct redox processes, which utilize similar experimental set-ups.
