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.

Future new-built fossil-fired power plants should be ready for the incorporation of a carbon capture plant at a later date, i.e. they should be “capture ready”. In the EU capture-ready assessment is mandatory for new fossil-fired power plants > 300 MW. Siemens has defined all capture-ready measures for standard steam power plants and combined cycle power plants.
Transport and storage of captured CO2 needs to be investigated and verified by the project owner.
