CO2- Sequestration concepts
(Pruschek/ Göttlicher)
(A) CO2- removal prior to combustion -gt
Membrane technology (B) CO2 - Concentration in
exhaust gas by O2/CO2 firing -gt Air
separation -gt CO2 - Recycling (C) CO2 -
removal from flue gas after combustion -gt
Flue gas scrubbing, Distillation,
CO2-Freezing (D) CO2 Separation from fuel (hydro
carbons) (E) CO2 separation/removal using fuel
cells

Zero emission- plant --gt cost up
CO2- sequestration and transport cause extra
costs

• Plant efficiency drop -- 20 -points down
• Estimated cost of electricity up -- 160 of

2nd CAME-GT- Conference, Bled Concluding remarks
(2)

• Convincing processes and thermodynamic cycles
  for
• zero emission power plants need yet to be
  defined
• Requirements of innovative cycles need new
  concepts
• in gas turbine design
• CO2- separation and transport, generation of
  synthetic fuels
• demand for higher attention on peripheral
  components
• Industrial compressors (radial and axial) for
  CO2-
• transport and air separation will become
• essential components of the power plant
• This fact is reflected by industrial compressor
  core
• projects in AG-TURBO - COOREFF

2nd CAME-GT- Conference, Bled Concluding remarks
(2)
In order to face all the technology needs in the
future a more pronounced partnership between
European Commission, national governments,
turbomachinery manufacturers and power
producers is of utmost importance
This partnership must be reflected in the 7th
Framework programme of the EU
