Carbon Dioxide Removal Testbed enables the center to be one of a few research facilities worldwide with a comprehensive understanding of carbon capture and storage, climate policy, certification, sorbent development, supply chain and long-range planning experience for climate change mitigation.&nbsp;<\/p>\n\n\n\n<p>The center houses several custom-made, state-of-the-art sorbent characterization systems that accommodate experimentation ranging in scale from milligrams to kilograms. This includes a methodology to quickly screen performance characterization of multiple sorbents for carbon capture in a short time, to enable sorbent scale up from mg to kg for a scale-up of sorbents from mg to kg. These methodologies evaluate essential environmental conditions (temperature, humidity, wind velocities) that affect sorbent performance.<\/p>\n\n\n\n<p>The center has successfully worked with both private and public sectors on sorbent characterization and synthesis since its formation in 2014. One of these successes was conducted in partnership with <a href=\"https:\/\/carboncollect.com\/\">Carbon Collect LLC<\/a>, and involved the scale-up of a sorbent from mg to hundreds of kg. It also instituted a program that placed a MechanicalTree<sup>TM<\/sup> prototype on ASU\u2019s Tempe campus for technology testing and evaluation.<\/p>\n\n\t<\/div>\n\n<\/div>\n\n<\/div>\n\n\n\n<div class=\"wp-block-cover is-light\"><span aria-hidden=\"true\" class=\"wp-block-cover__background has-background-dim-0 has-background-dim\" style=\"background-color:#FFF\"><\/span><img loading=\"lazy\" decoding=\"async\" width=\"1920\" height=\"548\" class=\"wp-block-cover__image-background wp-image-1161\" alt=\"\" src=\"http:\/\/globalfutures.asu.edu\/cnce\/wp-content\/uploads\/sites\/3\/2025\/05\/GF93761.jpg\" data-object-fit=\"cover\" srcset=\"https:\/\/globalfutures.asu.edu\/cnce\/wp-content\/uploads\/sites\/3\/2025\/05\/GF93761.jpg 1920w, https:\/\/globalfutures.asu.edu\/cnce\/wp-content\/uploads\/sites\/3\/2025\/05\/GF93761-300x86.jpg 300w, https:\/\/globalfutures.asu.edu\/cnce\/wp-content\/uploads\/sites\/3\/2025\/05\/GF93761-1024x292.jpg 1024w, https:\/\/globalfutures.asu.edu\/cnce\/wp-content\/uploads\/sites\/3\/2025\/05\/GF93761-768x219.jpg 768w, https:\/\/globalfutures.asu.edu\/cnce\/wp-content\/uploads\/sites\/3\/2025\/05\/GF93761-1536x438.jpg 1536w\" sizes=\"auto, (max-width: 1920px) 100vw, 1920px\" \/><div class=\"wp-block-cover__inner-container is-layout-constrained wp-block-cover-is-layout-constrained\"><div class=\"wp-bootstrap-blocks-container container mb-0 my-6 my-lg-10 container-sm\">\n\t\n\n<div class=\"wp-block-group p-4 has-white-background-color has-background is-layout-constrained wp-block-group-is-layout-constrained\"><div class=\"wp-bootstrap-blocks-row row\">\n\t\n\n<div class=\"col-12 col-md-6 mb-4\">\n\t\t\t\n\n<h3 class=\"wp-block-heading\">The Center for Negative Carbon Emissions facilities can be divided into distinct categories related to carbon removal:<\/h3>\n\n\t<\/div>\n\n<\/div>\n\n\n<div class=\"wp-bootstrap-blocks-row row\">\n\t\n\n<div class=\"col-12 col-md-6\">\n\t\t\t\n\n<ul class=\"uds-list wp-block-list\">\n<li>Sorbent capacity, kinetics characterization and scale-up from mg to kg.<\/li>\n\n\n\n<li>Outdoor test pad experiments for carbon capture and\/or storage (technology validation studies).<\/li>\n\n\n\n<li>Data interpretation and presentation based on ASU or client research.<\/li>\n\n\n\n<li>Technical results interpretation, analysis and application recommendations.<\/li>\n\n\n\n<li>Sorbent synthesis and form factors for better performance.<\/li>\n\n\n\n<li>Feasibility studies for climate mitigation applications.<\/li>\n\n\n\n<li>Certification of CO<sub>2<\/sub> removal services, advice, structural applications and proof of concept.<\/li>\n<\/ul>\n\n\t<\/div>\n\n\n\n<div class=\"col-12 col-md-6\">\n\t\t\t\n\n<ul class=\"uds-list wp-block-list\">\n<li>Removal certification, 3rd party analysis and recommendations.<\/li>\n\n\n\n<li>Mathematical modeling.<\/li>\n\n\n\n<li>Industrial carbon management analysis, including recommendations for alternative applications and approaches.<\/li>\n\n\n\n<li>Analysis of carbon storage including feasibility, site preferences and alternative considerations.<\/li>\n\n\n\n<li>Conceptual analysis services that may include recommendations for new technologies or applications.<\/li>\n<\/ul>\n\n\t<\/div>\n\n<\/div>\n<\/div>\n\n<\/div>\n<\/div><\/div>\n\n\n<section class=\"uds-section bg topo-black \" ><div class=\"acf-innerblocks-container\">\n<div class=\"wp-bootstrap-blocks-container container mb-0\">\n\t\n\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\"><div class=\"wp-bootstrap-blocks-row row\">\n\t\n\n<div class=\"col-12 col-md-6\">\n\t\t\t\n\n<h2 class=\"wp-block-heading\"><span class=\"highlight-gold\">Facilities bench-scale systems<\/span><\/h2>\n\n\t<\/div>\n\n<\/div>\n\n\n<div class=\"wp-bootstrap-blocks-row row\">\n\t\n\n<div class=\"col-12\">\n\t\t\t\n\n<div class=\"wp-block-unity-carousels-card-carousel\" data-per-view=\"2\" data-max-width=\"1200px\" data-card-items=\"[{&quot;id&quot;:0,&quot;imageSource&quot;:&quot;http:\/\/globalfutures.asu.edu\/cnce\/wp-content\/uploads\/sites\/3\/2025\/05\/GFC5E21.jpg&quot;,&quot;imageAltText&quot;:&quot;image alt text&quot;,&quot;title&quot;:&quot;Moisture swing closed system device and temperature swing milligram scale device &quot;,&quot;content&quot;:&quot;This system is capable of screening moisture and temperature swing sorbents on the kinetics quickly and can absorb and desorb CO<sub&gt;2<\/sub&gt;.

Depending on the experimental objectives, the CO<sub&gt;2<\/sub&gt; partial pressure can be fixed or dynamic between 400 ppm and 100% CO<sub&gt;2<\/sub&gt;. For direct air capture evaluation, CO<sub&gt;2<\/sub&gt; is typically set at 400 ppm to mimic atmospheric conditions. The sorbents to be evaluated are in the gram scale (0.1-2.0g).

The reactor can consider CO<sub&gt;2<\/sub&gt; desorption (regeneration) with 80-95\u00b0 C steam. CO<sub&gt;2<\/sub&gt; absorption capacity can be evaluated in two ways: \\n\\n          1) In-situ testing, the absorption is performed indoors with a blower \\n          2) Ex-situ testing, the
