Our group, led by Prof. Ryan Lively and postdoctoral researcher Seoyul Kim, has developed a promising new method for direct air capture (DAC) that is both low-cost and scalable. By using near-cryogenic cold from liquefied natural gas (LNG) regasification combined with widely available physisorbents (such as Zeolite 13X and CALF‑20), this approach achieves high CO₂ uptake without the need for expensive dehumidification.
Techno-economic analysis suggests this method could reduce capture costs to about $70 per ton of CO₂ — roughly one-third of current DAC technologies. Integrating this process with LNG infrastructure enables deployment in humid coastal regions and could help remove over 100 million metric tons of CO₂ annually by 2050.
