Amine‐containing facilitated transport membranes (AFTMs) are emerging membranes and have great potential for CO2 capture. AFTMs are particularly suitable for humid flue gases, as water vapor enhances the facilitated transportation of CO2. However, there is a lack of mathematical models available to evaluate the impact of water vapor on CO2 separation performance for large‐scale membrane modules. Therefore

Why do we need ‘renewable carbon’? In order to fight climate change, we need to curb our consumption of fossil resources. This has been shown in many studies and several of them even quantify how much of the remaining fossil resources need to be left in the ground. In the energy sector, this is possible through ‘decarbonisation’. However, this strategy is not feasible for organic chemistry, which is
