Developing “good” membrane modules and materials is a key step towards reducing the cost of membrane-based CO₂ capture. While this is traditionally being done through incremental development of existing and new materials, this paper presents a new approach to identify membrane materials with a disruptive potential to reduce the cost of CO₂ capture for six potential industrial and power generation cases. For each case, this approach first identifies the membrane properties targets required to reach cost-competitiveness and several cost-reduction levels compared to MEA-based CO₂ capture, through the evaluation of a wide range of possible membrane properties. These properties targets are then compared to membrane module properties which can be theoretically achieved using 401 polymeric membrane materials, in order to highlight 73 high-potential materials which could be used by membrane development experts to select materials worth pushing towards further development once practical considerations have been taken into account. Beyond the identification of individual materials, the ranges of membrane properties targets also show the strong potential of membrane-based capture for industrial cases in which the CO₂ content in the flue gas is greater than 11%, and that considering CO₂ capture ratios lower than 90% would significantly improve the competitiveness of membrane-based capture and lead to potentially significant cost reduction. Finally, it is important to note that the approach discussed here is applicable to other separation technologies and applications beyond CO₂ capture, and could help reduce both the cost and time required to develop cost-effective technologies.

一种新的鉴定高潜力材料的新方法，可用于经济高效的基于膜的燃烧后CO ₂捕集†

开发“好的”膜组件和材料是降低基于膜的CO ₂捕集成本的关键步骤。传统上，这是通过现有材料和新材料的增量开发来完成的，但本文提出了一种新的方法来识别具有破坏性潜力的膜材料，以减少六种潜在的工业和发电案例的CO ₂捕集成本。对于每种情况，与基于MEA的CO ₂相比，该方法首先确定达到成本竞争力和几个成本降低水平所需的膜性能目标通过评估各种可能的膜性能来捕获。然后将这些性能指标与使用401聚合膜材料在理论上可以实现的膜组件性能进行比较，以突出显示73种高潜力材料，一旦有实际考虑，膜开发专家可以使用这些材料来选择值得进一步开发的材料被考虑在内。除了确定单个材料之外，膜性能目标的范围还显示了在工业案例中基于膜的捕集的强大潜力，在工业案例中，烟道气中的CO ₂含量大于11％，并且考虑到了CO ₂低于90％的捕集率将大大提高基于膜的捕集的竞争力，并可能显着降低成本。最后，重要的是要注意，此处讨论的方法适用于CO ₂捕集以外的其他分离技术和应用，并且可以帮助减少开发具有成本效益的技术所需的成本和时间。
