That warming process often uses seawater as the source of the heat and essentially wastes the low temperature energy embodied in the liquified natural gas.<\/p>\n<p>Instead, by using the cold energy from LNG to chill the air, Georgia Tech researchers created a superior environment for capturing CO\u2082 using materials known as &#8220;physisorbents,&#8221; which are porous solids that soak up gases.<\/p>\n<p>Most DAC systems in use today employ amine-based materials that chemically bind CO<sub>2<\/sub> from the air, but they offer relatively limited pore space for capture, degrade over time, and require substantial energy to operate effectively. Physisorbents, however, offer longer lifespans and faster CO\u2082 uptake but often struggle in warm, humid conditions.<\/p>\n<p>The research study showed that when air is cooled to near-cryogenic temperatures for DAC, almost all of the water vapor condenses out of the air. This enables physisorbents to achieve higher CO\u2082 capture performance without the need for expensive water-removal steps.<\/p>\n<p>&#8220;This is an exciting step forward,&#8221; said Professor Ryan Lively of ChBE@GT. &#8220;We&#8217;re showing that you can capture carbon at low costs using existing infrastructure and safe, low-cost materials.&#8221;<\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2025\/study-demonstrates-low-1.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2025\/study-demonstrates-low-1.jpg\" data-sub-html=\"Postdoctoral researcher Seo-Yul Kim and Professor Ryan Lively.

Zeolite 13X is an inexpensive and durable desiccant material used in water treatment, while CALF-20 is a metal-organic framework (MOF) known for its stability and CO<sub>2<\/sub> capture performance from flue gas, but not from air.<\/p>\n<p>These materials showed strong CO\u2082 adsorption at -78\u00b0C (a representative temperature for the LNG-DAC system) with capacities approximately three times higher than those found in amine materials that operate at ambient conditions. They also released the captured and purified CO\u2082 with low energy input, making them attractive for practical use.<\/p>\n<p>&#8220;Beyond their high CO<sub>2<\/sub> capacities, both physisorbents exhibit critical characteristics such as low desorption enthalpy, cost efficiency, scalability, and long-term stability, all of which are essential for real-world applications,&#8221; said lead author Seo-Yul Kim, a postdoctoral researcher in the Lively Lab.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Leveraging_existing_infrastructure\"><\/span>Leveraging existing infrastructure<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The study also addresses a key concern for DAC: location. Traditional systems are often best suited for dry, cool environments. But by leveraging existing LNG infrastructure, near-cryogenic DAC could be deployed in temperate and even humid coastal regions, greatly expanding the geographic scope of carbon removal.<\/p>\n<p>&#8220;LNG regasification systems are currently an untapped source of cold energy, with terminals operating at a large scale in coastal areas around the world,&#8221; Lively said. &#8220;By harnessing even just a portion of their cold energy, we could potentially capture over 100 million metric tons of CO\u2082 per year by 2050.&#8221;<\/p>\n<p>As governments and industries face increasing pressure to meet net-zero emissions goals, solutions like LNG-coupled near-cryogenic DAC offer a promising path forward. The next steps for the team include continued refinement of materials and system designs to ensure performance and durability at larger scales.<\/p>\n<p>&#8220;This is an exciting example of how rethinking energy flows in our existing infrastructure can lead to low-cost reductions in carbon footprint,&#8221; Lively said.<\/p>\n<p>The study also demonstrated that an expanded range of materials could be employed for DAC. While only a small subset of materials can be used at ambient temperatures, the number that are viable grows substantially at near-cryogenic temperatures.<\/p>\n<p>&#8220;Many physisorbents that were previously dismissed for DAC suddenly become viable when you drop the temperature,&#8221; said Professor Matthew Realff, co-author of the study and professor at ChBE@GT. &#8220;This unlocks a whole new design space for carbon capture materials.&#8221;<\/p>\n<div class=\"article-main__more p-4\">\n<p><strong>More information:<\/strong><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\tSeo-Yul Kim et al, Near-cryogenic direct air capture using adsorbents, <i>Energy &amp; Environmental Science<\/i> (2025). <a rel=\"nofollow\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1039\/D5EE01473E\" target=\"_blank\">DOI: 10.1039\/D5EE01473E<\/a><\/p>\n<\/p><\/div>\n<div class=\"d-inline-block text-medium my-4\">\n                                                Provided by<br \/>\n                                                                                                    Georgia Institute of Technology<br \/>\n                                                    \t\t\t\t\t\t\t\t\t\t\t\t\t<a rel=\"nofollow\" target=\"_blank\" class=\"icon_open\" href=\"http:\/\/www.gatech.edu\/\" target=\"_blank\" rel=\"nofollow\"><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<svg>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<use href=\"https:\/\/techx.b-cdn.net\/tmpl\/v2\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/svg><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>\n                                                <strong>Citation<\/strong>:<br \/>\n                                                Low-cost method can remove CO\u2082 from air using cold temperatures and common materials (2025, July 7)<br \/>\n                                                retrieved 7 July 2025<br \/>\n                                                from https:\/\/techxplore.com\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2025-07-method-air-cold-temperatures-common.html\n                                            <\/p>\n<p>\n                                            This document is subject to copyright.
