Oxy-Combustion ProcessAdvantages• Reliability: main components exist,

only adaptation to power gen and scale-up

• All types of boilers / firing systems adaptable to Oxy covering a complete fuel range

• Rapid scale-up to large size (1,000 MWe range) possible after large demos.

• Retrofit in Oxy feasible• High efficiency and competitiveness

of supercritical/ultra-supercritical cycles and large unit size will be compatible and key benefits

• Large community involved in development, contributing to reaching solid consensus

• Major large oxy pilot projects underway; Alstom active in Schwarze Pumpe, Lacq,and own labs

• These pilot programs are providing very positive feedback and, in particular, represent a strong foundation for design of next-step demonstration

• Alstom is ready for large-scale demonstration of oxy-fired PC and CFB power plants
