Clean coal power plants use advanced systems to reduce emissions of carbon dioxide (CO₂) and other greenhouse gases produced from coal use. Seven main technologies are helping make this process cleaner and more efficient:

• Carbon capture and storage.
• Flue gas desulfurization.
• Fluidized-bed combustion.
• Integrated gasification combined cycle (IGCC).
• Low nitrogen oxide burners.
• Selective catalytic reduction (SCR).
• Electrostatic precipitators.
