In chemical DAC systems, large volumes of air are brought into contact with materials that bind CO\u2082. After the sorbent\/solvent is saturated with CO\u2082, the material is isolated from the air and the CO\u2082 is extracted. This regenerates the working material for use in the next extraction cycle. The CO\u2082 is then sequestered (DACCS) or, if desired, utilized for industrial purposes (DACCU).<\/p>\n<p><strong>Main advantages of DAC chemical systems<\/strong>:<\/p>\n<ul>\n<li><strong>Simple output:<\/strong> DAC chemical devices produce concentrated CO\u2082 outputs that are easy to measure. The output is a relatively pure stream of CO\u2082.<\/li>\n<li><strong>Less impact on land area:<\/strong> DAC chemical plants have a significantly smaller land footprint than most terrestrial CDR systems, whether single-use or biological systems of comparable capacity. Even when DAC systems are powered by specialized renewable energy systems, such as a solar array, the land footprint required is still smaller than that required for other approaches, such as BECCS.<\/li>\n<li><strong>Location flexibility:<\/strong> Facilities can be located to optimize the availability of waste heat or renewable energy sources, water requirements, proximity to CO\u2082 sequestration sites, operating environment (such as temperature and humidity), and geopolitical considerations.<\/li>\n<li><strong>Manageable Measurement, Reporting and Verification (MRV):<\/strong> MRV should be more straightforward for DAC chemical facilities than for most other large-scale proposed CDR systems.<\/li>\n<\/ul>\n<p><strong><em>Spring<\/em><\/strong><\/p>","protected":false},"excerpt":{"rendered":"<p>Chemical Direct Air Extraction (DAC) is a carbon dioxide removal (CDR) technology that involves removing CO\u2082 directly from the air using a working material, such as a solid sorbent or a liquid solvent.
