ORNL crystals capture CO2 directly from airGUANIDINESCRYSTALLIZATIONCARBON sequestrationThe article discusses the study which shows that when guanidine solution crystallises, it captures carbon dioxide (CO2) from ambient air which could be useful in CO2 direct air capture.Chemical Engineer, The...
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...
the CO2concentration in the air is only around 0.04 percent. This is about 300 times lower than what comes from the exhaust gas in a coal-fired power station.
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...
Post-combustion CO2 capture and capture using oxyfuel combustion of solid fuels show about equal increases in primary energy use. For post-combustion this increase is mainly determined by the heat requirement in the capture process. In oxyfuel combustion the separation of oxygen...
E New Technology: Carbon Capture ()To reduce CO2 in the air, the European Union has set up strict regulations (法规) over the past few years, and most European car companies have begun to move to electric vehicle(交通工具) production under the new regulations. However, their efforts are fa...
Researchers at Monash University have developed a group of low-cost solid materials that show great promise for use in systems to capture excess carbon dioxide (CO2) directly from the atmosphere. Known as “meso-macroporous melamine formaldehyde (MF)”, the new materials can be made relatively ea...

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 pe...
