4 Siemens Post-Combustion Carbon Capture for Fossil-Fired Power Plants CO 2 absorption, desorption is proven technology in chemical processing and oil & gas industry SIEMENS PostCap TM Process based on: AMINO ACID SALT formulations Scalable market introduction, retrofitable to existing power plants Preferred solution for CCUS demonstration projects Task: Mastering scale-up from pilot to demonstration plant. validated in pilot plant SPP w/ PostCap TM process Page 4 Energy Sector Siemens AG 2012

5 Siemens Lab Plant for CO 2 Capture Tests at Frankfurt Hoechst Industrial Park Desorption column Synthetic gas flue gas mixtures Reboiler made of glass so that boiling retardation effects can be recognized Absorption column with operating pressure up to 10 bar Fully automated DCS system NDIR CO 2 analytics Siemens Energy runs a fully automated lab plant for CO 2 capture for 24/7 operation. Currently: more than 5,000 hours. Page 5 Energy Sector Siemens AG 2012

6 Siemens PostCap TM : Lower CAPEX and OPEX, with Best Environmental Rating Competition has volatile solvent in exhaust gas; additional washing units required SIEMENS does not require it Cleaned flue gas Solvent slip nearly zero CO 2 outlet Solvent reclaiming Solvent refill Solvent deactivation due to degradation (thermal, O 2, NO x, SO x, etc...) Flue gas inlet 2.7 GJ / ton CO 2 captured Solvent recycling Sellable sulfur component Waste Capture process Targets for fossil Power Generation w/ CCUS: lowest Levelized Cost of Electricity (LCOE) / Targets for EOR: lowest cost per ton of CO 2 captured.
