While conventional processes require higher temperatures and larger amounts of energy for regeneration, SAFE-CO<sub>2<\/sub> pursues an innovative approach based on thermoresponsive adsorbent materials.<\/p>\n<p>The focus is on special materials that can bind CO<sub>2<\/sub> to their surface. These adsorbents consist of polymers that change when heated. At relatively low temperatures (target: 70\u00b0C), they release the previously absorbed CO<sub>2<\/sub>. This allows the absorption and release to be controlled in a targeted manner. The materials are designed to absorb large amounts of CO<sub>2<\/sub>, react quickly, and function reliably even after many cycles of use.<\/p>\n<p>To allow large volumes of air to flow through the system with little resistance, the adsorbers are embedded in porous, sponge-like structures. These structures are known from membrane technology and enable low pressure loss. At the same time, the heat supply is designed so that only the adsorbers are heated as far as possible. Part of the heat used is to be reused in order to further reduce energy consumption.<\/p>\n<p>Three partners with different areas of expertise are collaborating on the project. The Institute of Polymer Chemistry at Saarland University is developing the new adsorbent materials. The Fraunhofer Institute for Interfacial Engineering and Biotechnology is designing the modules and porous structures, and the Center for Solar Energy and Hydrogen Research is testing the performance and developing suitable processes. In addition, the environmental friendliness and economic viability of the process are being evaluated in comparison to existing solutions.<\/p>\n<p>Overall, SAFE-CO<sub>2<\/sub> aims to demonstrate that direct CO<sub>2<\/sub> capture from the air is technically feasible, low in energy consumption, and usable in the long term. The project thus makes an important contribution to future climate protection technologies. In the long term, the technology can help offset unavoidable emissions and provide CO<sub>2<\/sub> as a raw material for industry, building materials, or chemical products, enabling sustainable value chains that promote climate-neutral processes and support the transition to a more environmentally friendly economy.<\/p>\n\n\t<\/div>\n\n<\/div>","protected":false},"excerpt":{"rendered":"<p>has developed switchable adsorbers in a structured bed for energy-efficient CO\u2082 capture.<\/p>\n","protected":false},"author":6,"featured_media":6726,"template":"","class_list":["post-6724","consortia","type-consortia","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 -
