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.
