Background The Intergovernmental Panel on Climate Change (IPCC) emphasizes the urgent need to remove CO2 from the atmosphere by the end of the century to limit global warming to below 2 °C. Direct Air Capture (DAC) is essential in all scenarios to meet this target, requiring the removal of about 1,000 gigatons of CO2. DAC systems use chemical sorbents...

Background Many current air-capture designs feature flat air contactor surfaces with air flow predominantly tangential to those surfaces. In many cases, it may be advantageous to induce some turbulence across the sheet to enhance transport into the depth of the material. In general, it is advantageous to create surface roughness that is designed to...

Background The accumulation of carbon dioxide (CO2) in the atmosphere has been documented to be the primary driver of global warming. The global average CO2 levels in the atmosphere continue to rise, with a predicted 1.5°C increase in global temperatures within the next two decades. The capture and storage of CO2 is an essential part of mitigating...
