However, a significant technological gap remains in the heating sector, which is largely characterized by decentralized biomass plants: practical and cost-effective CO\u2082 capture solutions for small- and medium-scale installations are still lacking. The CarbonateClusters project addresses this key challenge on the path toward climate neutrality.<br \/>\nThe project focuses on two central research questions: How can the established carbonate looping process be adapted for decentralized, small-scale biomass systems? And how can innovative technologies enable high CO\u2082 capture rates while maintaining strong energy efficiency and economic viability?<br \/>\nThe objective is to develop so-called &#8220;Regional Carbonate Looping Clusters&#8221;. This concept involves capturing biogenic CO\u2082 directly at numerous small biomass combustion plants and subsequently releasing it at larger, regional facilities. Two key technologies are at the core of this approach: an electrically heated steam calciner that produces highly reactive calcium oxide (CaO), and a novel CO\u2082 adsorber based on hot gas filtration, enabling efficient capture at elevated temperatures. In addition, the project analyzes economic and societal aspects to assess the technology&#8217;s market potential and public acceptance.<br \/>\nThe project is based on the Carbon Dioxide Removal (CDR) method Bioenergy with Carbon Capture and Storage (BECCS). In this process, CO\u2082 is captured from flue gases by reacting it with CaO to form calcium carbonate (CaCO\u2083). This compound is then decomposed in a central calciner, releasing concentrated CO\u2082 that can be permanently stored in geological formations. By using renewable energy in the process, the system enables net-negative emissions.<\/p>\n\n\t<\/div>\n\n<\/div>","protected":false},"excerpt":{"rendered":"<p>develops Carbonate Looping Clusters for the Carbon Capture from biomass combustion plants.<\/p>\n","protected":false},"author":12,"featured_media":7755,"template":"","class_list":["post-7753","consortia","type-consortia","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 -
