The potential of different capture technologies

The document discusses different carbon capture technologies for power plants, including post-combustion, pre-combustion, and oxy-combustion approaches. Post-combustion using amine scrubbing is the most commercially ready but is also the most energy intensive. Pre-combustion with integrated gasification combined cycle shows potential for improved efficiency. Oxy-combustion is promising for coal plants and a 30MW demonstration plant is under commissioning. All approaches face challenges around energy requirements, corrosion, and CO2 purification that require further technological advances.
