Post-Combustion Carbon Capture
General Information
- Description
- Benefits
Post-combustion carbon capture means scrubbing the CO2 from the flue gas of fossil-fired power plants. It represents one of several technologies to reduce CO2 emissions from fossil-fired power plants in oder to mitigate climate change. Siemens offers a proprietary process using amino-acid salt formulations, the PostCap process, for post-combustion carbon capture. Post-combustion carbon capture can be applied in new power plants, but also retrofitted to existing power plants. Furthermore, new power plants can be planned capture-ready in order to enable or facilitate later retrofit of a post-combustion carbon capture plant.

Siemens Proprietary Post-Combustion Capture Process (PostCap)
- Description

- References
Siemens has developed and optimized a proprietary post-combustion carbon capture process based on amino acid salts (PostCap). This technology is designed for both new fossil-fired power plants and for retrofitting existing plants.
The Siemens CO2 capture process features several significant environmental and energy efficiency advantages compared to first generation technologies, e.g. the monoethanolamine (MEA) process.
Siemens' PostCap process is characterized by nearly zero emissions as well as low environmental impact and auxiliary energy needs through the use of an aminoacid salt solution and optimized process setup.
Having all necessary technologies in-house (power plant, flue gas treatment, capture process, CO2 compressor, instrumentation and control solution, service), Siemens is in the unique position to offer a fully optimized carbon capture power plant system.
