// CORA - CO2 Separation with Tissue Materials / 2021-2025

The CORA project developed and tested an innovative technology for the direct capture of carbon dioxide from the ambient air. The aim was to efficiently extract CO₂ from the atmosphere and make it available as a sustainable carbon source for downstream applications – for example, for synthetic fuels, chemical feedstocks or long-term storage in materials.

The project was funded by the Federal Ministry of Education and Research (BMBF) from April 2021 to March 2025 with a total budget of €1.815 million. In addition to the Centre for Solar Energy and Hydrogen Research Baden-Württemberg, the project partners included the German Institute for Textile and Fibre Research in Denkendorf and the ifeu – Institute for Energy and Environmental Research in Heidelberg. 
The focus was on developing a scalable, energy-efficient and continuously operated process for the simultaneous capture of CO₂ and water vapour from the air.

In this project, the ZSW undertook key research and development tasks along the early stages of the process chain. These primarily included investigating the materials under real-world conditions, assessing their performance in continuous process operation, and demonstrating the overall process on a laboratory scale by integrating the developed components into a fully functional system as a basis for subsequent scaling up. 
In addition to technological development, the project also examined issues relating to industrial feasibility, environmental assessment and potential uses for the captured CO₂. This created a sound basis for the further development and potential application of the technology.
