MissionDAC explores the molecular mechanisms of moisture-driven direct air capture, particularly sorbent materials that release captured CO2 using moisture instead of energy-intensive heat or vacuum pressure. This project uses advanced computer studies to understand how structural and chemical changes within sorbents drive CO2 capture and release.
The models pull from x-rays, electron beams and gas flow systems to reveal how these materials are structurally organized and how they transport water, ions and carbon. MissionDAC aims to increase CO2 capturing capacity, manufacture durable materials and accelerate both capture and release rates.
Technology development for things like batteries, fuel cells and water purification have the potential to benefit from this work. The project brings together researchers from Northern Arizona University, Arizona State University and the University of Texas at Austin. It is led by Jennifer Wade at NAU and sponsored by the Department of Energy under award #DE-SC0023343.
