The capture performance of the 1.5 mol dm3diamine solutions was evaluated on the basis of the CO2absorption efficiency from an atmospheric air stream, continuously measured by means of a gas chromatograph during 24-hour bench-scale absorption experiments, carried out in an absorption column ...
Now, Joachim Sauer, Omar Yaghi and co-workers report the direct capture of CO2 from open air using a covalent organic framework (COF). The authors strategy involves constructing a porous, crystalline COF containing pores decorated with polyamines. The COF material was synthesized through Knoevenagel...
Direct air capture Direct air capture (DAC) is still a very expensive technology with a high potential for improvement. The high cost of current DAC processes would place a considerable weight on the economics of any CO2capture and utilization system. Therefore, the first objective of Sabatino's...
Capturing CO2 from air, referred to as air capture, is being proposed as a viable climate change mitigation technology. Technically, air capture is not a new technology; industrial applications can be traced back to the 1930s. This paper explores the feasibility of this technology as a climate...
The calculated free energy for crystallization of GBIGH2(HCO3)2(H2O)2 from air, –7.4 kJ/mol CO2,17 indicates a thermodynamically favorable reaction but not necessarily an effective DAC process. When left open to air, an aqueous solution of GBIG led mostly to crystallization of the hydrated ...
Current climate targets require negative carbon dioxide (CO2) emissions. Direct air capture is a promising negative emission technology, but energy and material demands lead to trade-offs with indirect emissions and other environmental impacts. Here, we
Driving your car or heating your home also releases CO2. Carbon dioxide can be captured at the source of the emissions, such as power plants or refineries, or even from the air itself. A range of technologies—some using membranes, others using solvents—can per...
