Siemens Remains Committed to Designing and Building Clean, Efficient Power Plants Worldwide By investing significant R&D in advanced coal technologies including

Ultra Supercritical Plants

Integrated Gasification CC Plants

By investing heavily in large manufacturing plants worldwide, including China The technology is available … the manufacturing is available … all that is needed is a commitment to use our precious resources more effectively March 7, 2006

What Should we do to Protect the Environment for Future Generations?  For Countries Rich in Natural Gas  Build high efficiency combined-cycle plants (but plan fuel diversity)  For Emerging Countries with Small Installed Grids and low Natural Gas Reserves  Build small (250-500 MW) coal plants using modern day subcritical technology with low NOX burners and post-combustion emissions controls for SO2 and particulates  For Emerging Countries Rich in Coal with Large Installed Grids and Mature Countries Rich in Coal  Continue to clean up/retire old coal-fired operating units  Build large (600-1000 MW) supercritical/ultrasupercritical coal plants with post-combustion emissions controls for NOX, SO2 and particulates  Embrace IGCC as it becomes more commercially available  Continue development toward CO2 capture
