Exhaust from power plants, refineries and industrial plants adds CO2 to the atmosphere. CO2 emissions account for 76% of greenhouse gases that cause global warming. Current methods of capturing CO2 emissions can be costly and often produce unusable outputs.

KAUST has developed techniques for capturing CO2 emissions from industrial sources – at about 50% less cost than other existing techniques. KAUST’s process cools plant exhaust to up to 130°-C to extract frozen CO2 from the rest of the gas that is now clean and free from nitrogen and sulfur. The process is highly energy efficient and results in pure liquid CO2, ready to transport and use.
