Fracking, Atomkraft und Verbrennungsmotor

Henrike Roßbach, Süddeutsche Zeitung, 26. Januar 2023, 11:59 Uhr

„Wenn die FDP „Technologieoffenheit“ sagt, meint sie in der Regel Dinge, die bei den Grünen starkes Unwohlsein auslösen. So geht das Pingpongspiel zwischen den ungleichen Parteien weiter. (…) Vertrackter für sie aber ist die Forderung, die unterirdische Speicherung von abgeschiedenem CO₂ aus Industrieprozessen (CCS) zu erlauben. Kürzlich erst hat der grüne Wirtschaftsminister Robert Habeck in Norwegen besichtigt, wie das funktionieren kann; Klimaexperten halten CCS für notwendig, um die Klimaziele zu erreichen. Die FDP will diese Technologie nun auch hierzulande im industriellen Maßstab kurzfristig zulassen. Man dürfe sich nicht „auf andere Länder verlassen, wie zum Beispiel Norwegen (…) Die einen fordern CCS und Fracking im eigenen Land (Ping), die anderen wollen Straßen von der Planungsbeschleunigung ausnehmen und Biokraftstoffe aus Pflanzen verbieten (Pong). Die einen fordern, die Sektorziele beim Klimaschutz aufzugeben (Ping). Die anderen verlangen von FDP-Verkehrsminister Volker Wissing, seine Sektorziele endlich zu erfüllen (Pong).“

Japan sets carbon capture roadmap with 6-12 million tonne/year target by 2030

on channelnewsasia.com; 26 Jan 2023 09:47PM

„TOKYO : Japan’s industry ministry on Thursday set a target of annual carbon dioxide (CO2) storage capacity of 6-12 million tonnes by 2030 under a long-term roadmap for carbon capture and storage (CCS). Japan sees CCS technology – which removes CO2 emissions from the atmosphere and stores them underground, and which a host of Japanese companies said on Thursday they were working on – as essential to achieving its goal of carbon neutrality by 2050.“

Phys.org – What Is Blue Carbon and How Can It Help Fight Climate Change?

by Olga Rukovets on Phys.org, 26 January

„According to the National Ocean Service, „blue carbon is simply the term for carbon captured by the world’s ocean and coastal ecosystems.“ So why is it important? And what role can it play in addressing climate change?“ Researchers at Columbia Climate School discuss the benefits and challenges of working with carbon from ocean and coastal ecosystems.

Und übermorgen unter null

Stefan Schmitt, ZEIT online, 25. Januar 2023 (Paywall)

„Emissionen senken, klar doch, dieses Klimaschutzrezept kennt jeder. Aber seinen unverzichtbaren Zwilling? Fachleute rechnen durch, wie viel Kohlendioxid im Lauf des Jahrhunderts aus der Luft geholt werden muss.“

Re-carbonizing the sea: Scientists to start testing a big ocean carbon idea

by Jeremy Hance, on mongabay.com, 25 January 2023

„Ocean alkalinity enhancement (OAE) involves releasing certain minerals into the ocean, sparking a chemical reaction that enables the seawater to trap more CO₂ from the air and mitigating, albeit temporarily, ocean acidification. Some scientists believe OAE could be a vital tool for drawing down and securely storing some of the excess CO₂ humanity has added to the atmosphere that is now fueling climate change. Yet many questions about OAE remain, including most prominently how it would impact marine life and ecosystems. Several programs are aiming to spark the research needed to answer these questions, including field tests in the ocean.“

Nature-Gruber et al. (2023): Trends and variability in the ocean carbon sink

Nicolas Gruber, Dorothee C. E. Bakker, Tim DeVries, Luke Gregor, Judith Hauck, Peter Landschützer, Galen A. McKinley, Jens Daniel Müller IN: Nat Rev Earth Environ (2023). https://doi.org/10.1038/s43017-022-00381-x

In this Review, the authors discuss trends and variations in the ocean carbon sink. The sink stagnated during the 1990s with rates hovering around –2 Pg C year–1, but strengthened again after approximately 2000, taking up around –3 Pg C year–1 for 2010–2019. The most conspicuous changes in uptake occurred in the high latitudes, especially the Southern Ocean.

Webinar on ocean-based CDR with CDRmare

Tuesday, February 7, 2023, 4 p.m. to 5 p.m.; hosted by Swiss Carbon Removal Platform

In this CDR Swiss webinar, Prof. Dr. Gregor Rehder and Prof. Dr. Achim Kopf from the German research mission „CDRmare“ will present marine Carbon Dioxide Removal (CDR) methods, including carbon storage in the oceanic crust (basalt formations) and in geological formations of the German North Sea (sand stone formations).
