![]() The dual-mode regeneration offers unique flexibility and facilitates using oceans as decarbonizing sinks to widen DAC application opportunities. 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. Just select a city on the map, review the full. However, the ultradilute atmospheric CO2 concentration (~400 parts per million) poses a formidable hurdle for high CO2 capture capacities using sorption-desorption processes. Now you can listen to the live broadcast of all FM and AM radio stations from major cities around the world. 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. ![]()
