Ambient and sub-ambient temperature direct air CO2 capture (DAC) by novel supported in situ polymerized amines

“…These solutions include reducing our reliance on fossil fuels, transitioning to green and renewable energy sources, and minimizing CO 2 point source emissions through methods such as chemical looping, oxy-combustion, amine absorption, or other CO 2 capture techniques before its release into the atmosphere. [9][10][11][12][13][14][15][16] However, it's important to note that these strategies primarily have the potential to slow the rate of increase of CO 2 in the atmosphere, as they may not fully address non-point sources of CO 2 emissions. 17,18 To address the challenge of increasing CO 2 concentrations and work towards achieving the goal of limiting the increase in Earth's average temperature to 1.5 °C or 2 °C by 2100, an alternative approach involves the use of negative emissions technologies (NETs).…”

Amine Sorbents for Sustainable Direct Air Capture: Long-Term Stability and Extended Aging Study

“…This surge has led to a significant increase in global atmospheric carbon dioxide (CO 2 ) concentrations, reaching 420 ppm in November 2023, as reported by NASA . CO 2 , recognized as a greenhouse gas (GHG) or heat-trapping gas, contributes to the greenhouse effect, leading to an increase in the Earth’s average temperature. − This temperature increase has far-reaching consequences, including but not limited to droughts, wildfires, floods, extreme heat waves, the melting of glaciers, and rising sea levels. − The magnitude and speed of these consequences are anticipated to escalate if no corrective actions are implemented.…”
