#DACCS, #CCS, Blauer #Wasserstoff, #EFuels sind Betrug
Genau diese Technologien stellt auch die neue Bundesregierung – insbesondere Wirtschaftsministerin Katherina #Reiche – in den Mittelpunkt ihrer sogenannten #Klimapolitik, anstatt konsequent den vollständigen Ausbau hin zu 100 % Erneuerbaren Energien voranzutreiben.
As this is Mastodon, let me pre-emptively point out that, yes, these scientists are aware that >90% of teaching Climate Neutrality is about emissions reductions, not removals.
The IPCC is also aware of this, as am I at the European Commission.
All these people already wrote reports on that, this one is about land sinks and technological removals.

EU Scientific Advisory Board on Climate Change comes out with new report on carbon removals.
They recommend, i.a.
“Separate targets, stronger innovation support and environmental safeguards…
Integrating permanent removals into the EU carbon market over time for a cost-effective deployment…
Reversing the EU’s land sink decline”

"OTEC is a form of electricity production that exploits the temperature difference between deep and shallow ocean waters, and can power DACCS on floating platforms at a price competitive with coal-generated electricity... We show that a safe and sustainable level of OTEC-generated electricity powering DACCS for 70 years could result in up to a 35% decrease in the relative global mean temperature warming compared to a business-as-usual emissions scenario."
Reaching net zero emissions and limiting global warming to 2 °C requires the widespread introduction of technology-based solutions to draw down existing atmospheric levels and future emissions of CO2. One such approach is direct air CO2 capture and storage (DACCS), a readily available, yet energy-intensive process. The combination of DACCS and ocean thermal energy conversion (OTEC) allows for independently powered carbon capture plants to inject concentrated carbon into deep marine sediments where storage is generally safe and permanent. OTEC is a form of electricity production that exploits the temperature difference between deep and shallow ocean waters, and can power DACCS on floating platforms at a price competitive with coal-generated electricity. Here we highlight the scale of the challenge facing society. We show that a safe and sustainable level of OTEC-generated electricity powering DACCS for 70 years could result in up to a 35% decrease in the relative global mean temperature warming compared to a business-as-usual emissions scenario.
Die Menschheit emittiert etwa 37.000.000.000 Tonnen CO2 pro Jahr.
Wie viel davon wird momentan durch Direct Air Carbon Capture and Storage pro Jahr wieder entfernt?
CO2-Entnahme aus der Atmosphäre. Darüber habe ich mit Jenny von Sperber vom BR gesprochen.
Wir müssen CO2 speichern - dafür hat sich Anfang Januar eine ungewöhnliche Koalition aus Industrie, Gewerkschaften und Naturschutzverbänden ausgesprochen. Und auch die EU plant, die CCS-Technologie zu fördern, um so ihre Klimaziele zu erreichen. In unserer heutigen Podcast Folge fragen wir, welche Chancen in der CO2-Abscheidung und -Speicherung liegen, aber auch welche Risiken.

Der neue Bericht des Global Carbon Project zeigt: Die fossilen CO2-Emissionen werden 2023 ein Rekordhoch erreichen. Bleiben die Emissionen so hoch, wird das verbliebene Kohlenstoffbudget zur Einhaltung der 1,5°C-Grenze voraussichtlich in sieben Jahren aufgebraucht sein. Eine Presseinformation der Ludwig-Maximilians-Universität München.

"The papers—“Why direct air carbon capture and storage (#DACCS) is not scalable, and ‘#NetZero’ is just a dangerous myth” and “Why scaling bioenergy and bioenergy with carbon capture and storage (#BECCS) is impractical and would speed up global warming”—serve as reminders that in the race to avert #climate calamity, all that glitters is not green."
