How does carbon capture work?

Carbon capture involves capturing CO2 from emission sources using chemical solvents, physical separation, or other technologies.

Carbon capture involves several methods. Post-combustion capture uses solvents to absorb CO2 from flue gasses. Pre-combustion capture converts fuel into a mix of hydrogen and CO2, then separates the CO2. Oxy-fuel combustion burns fuel in oxygen, producing CO2 and water vapor, which are easier to separate. These methods are integrated into industrial processes or power plants to reduce CO2 emissions before they reach the atmosphere.
