Amine- and Ammonium-Modified Silicones for Direct Air Capture of CO2
Background The field of carbon dioxide (CO2) capture is rapidly growing due to an increasing need to effectively remove CO2 from the atmosphere. New technologies are currently being developed to target CO2 in various types of sources. One particular method of CO2 capture that has gained traction in recent years is membrane-based separation, which is...

Combining Air Capture and Water Splitting for Generating Carbon Dioxide and Hydrogen for Synthetic Fuel Production
Background The conversion of solar energy to fuels requires both water (H2O) and carbon dioxide (CO2) as feedstocks. These feedstocks provide the carbon and hydrogen atoms necessary to form hydrocarbons. By removing oxygen from one or both of these compounds, liquid hydrocarbon fuels can be produced. Water can be converted into hydrogen and oxygen...

The Chimney for CO2 Direct Air Capture – Enhanced Airflow for Capture
Background The removal of CO2 from the atmosphere through direct air capture (DAC) can help to stabilize the planet’s climate. There is a need for large-scale negative emission systems as more CO2 will need to be captured and stored in the future. There are existing DAC systems for carbon capture using airflow, which can use large fans to bring...

CO2 Capture & Harvest with Turbulence
Background Carbon dioxide (CO2) removal from the atmosphere is a critical factor in mitigating climate change. There are many current technologies being used for CO2 capture, including CO2 removal technologies from ambient air. These technologies typically use sorbent materials or mechanisms that involve laminar flow of air, which can sometimes provide...

AUDACity: DAC Polymer-Enhanced Cyanobacterial Bioproductivity
Background Carbon dioxide removal (CDR) methods from atmospheric air, including direct air capture (DAC), is essential to limit the spread of global warming. However, current DAC approaches based on thermal and pressure swings are very energy intensive. Moisture-driven DAC using strong-base anion exchange resins (AER) reversibly binds CO2 from ambient...

Methods and Systems for Capturing and Concentrating CO2 Using Mesh Tubes
Background Carbon dioxide removal (CDR) from atmospheric air, which includes direct air capture (DAC), is essential to limit global warming to 2°C, or ideally 1.5°C. Current DAC methods based on thermal and pressure swings remain too energy intensive. Moisture-driven DAC using strong-base anion exchange resins (AER) binds CO2 from ambient air...

Design and Application of Form Factors for Sorbent Materials
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...

Electrospun Poly(Vinyl Alcohol) – L-Arginine Nanofiber Composites for Direct Air Capture of CO2
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...
