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.

- References
Front-End Engineering and Design (FEED) studies are offered to customers who need site-specific process design, train concept and cost estimation for a carbon capture plant, as well as information on integration requirements into the power plant.
The documents and information obtained with a FEED study can provide a basis for investment and funding decisions.
