Im neuen Jahr geht es direkt weiter mit der Vortragsreihe der #S4F Osnabrück. Diesen Mittwoch geht es um #CarbonCaptureAndStorage mit Schwerpunkt #DACCS. Vortragende - bin ich diesmal selbst.

Wie immer wird der Vortrag aufgezeichnet. Wenn Ihr die Diskussion auch mitgekommen möchtet, dann geht das nur im google-freien Livestream, der dann hier läuft:

Selbstredend beginne ich mit einem kurzen Update wo wir stehen bzgl. #Klimakrise

New research suggests IPCC AR6 greatly over-estimated subsurface carbon storage potential at rates of 1 – 30 GtCO2 yr−1 by 2050. “These projections, however, overlook potential geological, geographical, and techno-economic limitations to growth.”

Research suggests a global storage rate of 5-6 GtCO2 yr−1, with the United States contributing around 1 GtCO2 yr−1.

NatureThe feasibility of reaching gigatonne scale CO2 storage by mid-century - Nature CommunicationsA study shows the maximum techno-economically constrained CO2 storage rate is 16 GtCO2 yr-1 by 2050, with 60% reliant on the USA, highlighting geographical discrepancies with current IPCC projections. A more feasible benchmark is 5-6 GtCO2 yr−1.

Season 3 Episode 3: Carbon Capture and Storage with Prof Mike Bickle

In this episode, Christina talks to Professor Mike Bickle about what methods for carbon capture and storage are the most promising (and the most likely for us to engage in), what some of the dangers are, what it would take to deploy carbon capture and storage at the scale required, and how long it might take us to bring an end to the global warming we’ve created. Prof. Bickle is professor emeritus at the Earth Sciences Department at the University of Cambridge.

Conquering climate change for our survival and that of much of the rest of the biosphere calls for more than attaining net zero emissions of greenhouse gasses to the atmosphere. We also need to actively remove much of the 140 extra parts per million of carbon dioxide currently up there in the atmosphere thanks to our burning of fossil fuels and destruction of so much of Earth’s biosphere. Both attaining net zero and going beyond it will take carbon capture and storage. This means capturing carbon dioxide from power plants and other point sources and from our agricultural activities before it gets into the atmosphere, as well as capturing carbon dioxide already in the atmosphere. Then, we need to store that carbon somewhere safely away from the atmosphere for at least a few thousand years.

"The report says capture is limited by both technical issues and the demand for carbon dioxide from the energy industry, which uses the gas to extract more oil from depleting reserves" --

So: the carbon from #CarbonCaptureAndStorage plants is used to pump MORE oil out of the ground; and if the oil industry won't buy it, the CCS plant is bypassed.

This is not an attempt to mitigate #ClimateChange at all -- and never was.
