Klimaschädliches Gas war Verlustgeschäft – jetzt wird es zum Milliardenmarkt

focus.online, 14.06.2023, 10:05 (Übersetzung eines Artikels in „The Economist“, 21.05.23)

„Umweltschädliches Kohlendioxid aus der Luft holen und wieder recyceln? Die „Direct Air Capture“-Anlage in Texas soll das möglich machen. Viele Unternehmen wollen die neue Entwicklung nutzen, um ihr Image zu polieren und bieten an, das CO2 zwischenzulagern – sie erkaufen sich damit Emissionsgutschriften.“

Carvalho et al. (2023): The role of construction materials by accelerated carbonation in mitigation of CO2 considering the current climate status: a proposal for a new cement production model

Vitor Carvalho, João Castro-Gomes, Shuqiong Luo IN: Innov. Infrastruct. Solut. 8, 187, https://doi.org/10.1007/s41062-023-01147-0

The importance of the construction sector (building and infrastructure) as a path to achieve climate neutrality, considering the new materials based on accelerated carbonation, is highlighted. Construction materials based on accelerated carbonation have the potential to use and store several quantities of CO2. This work brings forward a new model of construction material production based on innovative technologies developed to reduce the concentration of CO2 in the atmosphere, also considering its economic viability.

Tripathi et al. (2023): Carbon capture, storage, and usage with microalgae: a review

Shweta Tripathi,  Sonia Choudhary,  Alok Meena, Krishna Mohan Poluri  IN: Environ Chem Lett, https://doi.org/10.1007/s10311-023-01609-y

Here the authors review carbon capture, usage, and storage with microalgae, with focus on methods to improve carbon dioxide uptake, systems combining wastewater and flue gases, machine learning for strain identification, artificial intelligence and automation, and the circular bioeconomy. Carbon dioxide uptake by microalgae can be improved by using modified photobioreactors, membranes, chemical methods, solvents, adapted strains, genetically engineered strains, omics, and nanotechnology.

Prasad et al. (2023): A review of the supercritical CO2 fluid applications for improved oil and gas production and associated carbon storage

Siddhant Kumar Prasad, Jitendra S. Sangwai, Hun-Soo Byun IN: Journal of CO2 Utilization 72, 102479, https://doi.org/10.1016/j.jcou.2023.102479

Supercritical fluids find use in various areas in oil and gas production operations due to their unique properties. Supercritical CO2 (sc-CO2) with its reduced viscosity, increased diffusivity, and liquid like density, is attractive for enhanced hydrocarbon recovery, shale gas fracturing and drilling (especially in underbalanced condition). However, many technical, financial and policy challenges need to be overcome to realize the success of the CO2-EOR/storage project and achieve carbon neutrality. This review paper discusses such challenges, the current mitigation practice, gaps and future direction of research.

CO2-Speicherung in anderen Ländern

Petra Krimphove, die Debatte, 23. März 2023

„Die industrielle Nutzung der CCS-Technologie nimmt deutlich an Fahrt auf. Laut dem „Global Status of CCS Report 2022“ gab es im vergangenen Jahr weltweit 33 kommerziell betriebene CCS-Anlagen. Elf weitere waren im Bau, 153 in Planung.“ In dem Artikel werden Beispiele für CCS-Technologien der Länder USA, Norwegen, Dänemark, Schweiz, Island, Kanada und Indien beschrieben.

Nature-Honegger (2023): Toward the effective and fair funding of CO2 removal technologies

Matthias Honegger IN: Nature Communications 14, 534, https://doi.org/10.1038/s41467-023-36199-4

Carbon dioxide removal technologies are gaining prominence in academia, industry and policy, yet the need for substantial funding raises serious challenges. This comment outlines these issues and charts a path for the effective, systematic and fair mobilization of funds for removals.

White Paper: Ocean-Based Carbon Dioxide Removal Practices

Release date: February 7, 2023; Foundation for Climate Restauration

This is the fifth installment of the Foundation’s Solution Series, which examines a diverse portfolio of natural and technological approaches that can remove CO2 from the atmosphere and return us to safe, preindustrial levels of carbon. In this paper, the authors explore Ocean-Based Carbon Dioxide Removal through a climate restoration lens. They discuss Ocean-Based CDR’s capacity to achieve scalable, financeable, durable, and equitable outcomes and then provide ways for readers to advocate for its safe and thoughtful implementation.
