Siemens Energy has successfully completed the first test phase with its CO2 capture process in a pilot facility at the Staudinger power plant operated by E.ON. With its innovative and particularly ecofriendly process the company is setting new benchmarks in CO2 capture in fossil-fueled power plants. Process efficiency, the long-term chemical stability of the scrubbing agent and emissions were investigated in the pilot facility under real power plant conditions. After over 3,000 operating hours since commissioning of the facility in September 2009, it has been demonstrated that the post-combustion capture process developed by Siemens (PostCap) attains a CO2 capture efficiency of over 90 percent with practically zero solvent emissions. The energy consumption is significantly lower than comparable conventional processes.
