Alstom’s strategy to stabilize CO2 emissions
1. Technology Mix Balancing the generation portfolio by
significantly increasing the share of renewables and CO2 free technology
2. Production Efficiency and Energy Management
(Smart Power) Efficiency is a key to emissions reduction
3. Carbon Capture and Storage With 60% of the installed base in 2030

Oxy-Combustion Process
• Reliable: main components exist, only adaptation to power gen and scale-up
• All types of boilers / firing systems adaptable to Oxy-combustion covering a complete fuel range
• Rapid scale-up to large size (1,000 MWe range) possible after large demos
• Retrofit 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

View of the Alstom GPU pilot unit in containers
Mobile GPU pilot unit for multiple testing possibilities
• Designed for stringent (>99% Vol.) or relaxed CO2 specification (>95% Vol.)
• Within the oxy process, the GPU represents : ~30% of the energy penalty & ~40% of the incremental capture system cost
• Developed from already-existing process
• Pilot configuration in containers to allow mobility to different sites
• Compression & Purification tests:
- 1st phase (on-going) with synthetic gases in Alstom R&D center in Växjö, Sweden
- 2nd phase (2012) on actual oxy-combustion flue gases on the 15 MWth BSF in Windsor, CT USA

Oxy-firing Integrated Approach Reference Plant work
• Globally optimize cost of electricity
• Balance trade-offs between main subsystems (performance and costs)
• Determine specification for the new subsystems
• Optimize power plant operation behaviour
• Optimize arrangement and minimize footprint
Guides the oxy-program and defines future commercial

Oxy-firing Integrated Approach Reference Plant
An integrated approach minimizes the cost of electricity
Learnings from subsystems development and pilots & demo projects are continuously integrated in the Reference Plant
• Guide component developments
• Optimize integration of plant system
• Support the demo projects
• Offer oxy-ready power plant designs in the pre-commercial period
• Offer oxy-effective power plants once demo projects will have been validated.
