DIRECT AIR CAPTURE OF CO2

Organic agents offer innovation

Capturing CO2 directly from the air could lead to negative emissions, but more efficient technologies are still required. Now, researchers use a multi-stage cycle based on amino acids and organic salts to capture CO2 from air, which can be released with concentrated solar power.
