If nothing changes, we are heading towards a 2.8-degree temperature rise – towards a dangerous and unstable world." These are the warning words of UN Secretary-General António Guterres, and they should motivate us, as scientists and engineers, to help close this gate. But will carbon dioxide capture from air and industrial flue gas streams help?This lecture will present different approaches and the major industrial players currently involved in this field. Misleading claims and announcements will be exposed. Direct Air Capture (DAC): Despite strong criticism, the direct capture of carbon dioxide from air is more popular than ever. On January 6, 2025, the U.S. Department of Energy announced funding opportunities totaling over $3.5 billion to develop carbon capture and transport technologies.
