InvisibleDAC is developing modular DAC systems that can be seamlessly integrated into building ventilation systems. Compared to large-scale DAC plants, such systems offer several advantages, particularly in densely populated countries. Among other things, faster implementation is expected. This is facilitated by simpler permitting processes and the use of existing technical infrastructure. Additionally, no additional land is required for new plants. Increased productivity is also anticipated due to higher CO\u2082 concentrations indoors.<\/p>\n<p>As the exhaust air from the ventilation system flows through the DAC system, it comes into contact with a liquid solvent that specifically binds the CO\u2082 contained in the exhaust air. When the air leaves the DAC system, it is largely free of CO\u2082. Electrochemical processes can be used to release the CO\u2082 from the solvent again. The captured CO\u2082 can then be collected via suitable infrastructure for permanent underground storage at specific locations (e.g., in the North Sea region). It can also be converted into sustainable products. Of particular interest here are, for example, durable recycled building materials and carbon-based construction materials. Chemical products (e.g., plastics) or fuels for specific applications that cannot be electrified are also conceivable.<br \/>\nThe project will further advance the concept and a selected DAC technology toward industrialization. In addition to research on DAC technology and its integration into building systems, various options for CO\u2082 logistics are also being investigated.<\/p>\n<p>By integrating innovative ventilation systems with built-in DAC systems into people\u2019s daily lives in the future, everyone could make a tangible contribution to CO\u2082 capture simply by breathing.<\/p>\n<\/div>\n\n\t<\/div>\n\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Development of efficient technologies and system integration for removing CO\u2082 from the air in buildings.<\/p>\n","protected":false},"author":12,"featured_media":8345,"template":"","class_list":["post-8339","consortia","type-consortia","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 -
