There’s always something good playing on SiriusXM. Sirius features 3 channels, including NPR Now, NPR Talk, and Public Radio International (a provider of public radio shows that is not affiliated with NPR). The dual-mode regeneration offers unique flexibility and facilitates using oceans as decarbonizing sinks to widen DAC application opportunities. Music, sports, talk, news, comedy, and more. In addition, seawater was validated as a viable regenerant, and the desorbed CO2 is simultaneously sequestered as innocuous, chemically stable alkalinity (NaHCO3). ![]() The hybrid sorbent, such as other amine-based sorbents, is amenable to thermal desorption at less than 90☌. Here, we present a Lewis acid-base interaction–derived hybrid sorbent with polyamine-Cu(II) complex enabling over 5.0 mol of CO2 capture/kg sorbent, nearly two to three times greater capacity than most of the DAC sorbents reported to date. However, the ultradilute atmospheric CO2 concentration (~400 parts per million) poses a formidable hurdle for high CO2 capture capacities using sorption-desorption processes. Graphic in comments.ĭirect air capture (DAC) is important for achieving net-zero greenhouse gas emissions by 2050. The new method could speed up the deployment of #carbonremoval technology. The warming gas can be transformed into bicarbonate of soda and stored safely and cheaply in #seawater. The scientists behind it say that this novel approach captures #CO2 from the atmosphere up to three times more efficiently than current methods. New science for sucking up CO2 from air and storing it in the sea shows promise.
