New technique to capture CO2 could reduce power plant …

Stripping. Power plants strip CO 2 from flue emissions today by bubbling flue gases through organic amines in water, which bind and extract the carbon dioxide. The liquid is then heated to 120-150 C (250-300 F) to release the CO 2 gas, after which the liquids are reused. The entire process consumes about 30% of the power generated.
