A successful changeover to a future energy system that does not add extra CO₂ to the atmosphere, a net-zero emission energy system, is likely to depend on a combination of known technologies enabled by scalable and modular devices. In this article, we discuss prominent technological opportunities and barriers for an integrated approach to carbon capture and utilization (CCU) that can simultaneously exploit both CO₂ and industrial wastes. We show that a hollow fiber module based on an ultrapermeable membrane synthesized with the polymers of intrinsic microporosity (PIM-1) has the potential to directly utilize CO₂ from the flue gas stack via a continuous solid carbonation reaction. By a quantitative comparative assessment of the continuous PIM-1 module performance for different testing conditions, feasible routes for large-scale CO₂ utilization are proposed. We also identified surmountable hurdles in our approaches, such as membrane stability and possible scale formation. An integrated approach of two parallel research streams, CO₂ capture and utilization, could provide reliable and cost-effective strategies for large-scale CCU.

通过超渗透性PIM-1中空纤维膜进行固体碳化以实现可扩展的CO ₂利用

成功转换为不向大气中添加额外CO ₂的未来能源系统（净零排放能源系统），很可能取决于可扩展和模块化设备支持的已知技术的组合。在本文中，我们将讨论可同时利用CO ₂和工业废物的碳捕集与利用（CCU）综合方法的重大技术机遇和障碍。我们表明，基于具有固有微孔性（PIM-1）的聚合物合成的超渗透膜的中空纤维组件具有直接利用CO ₂的潜力通过连续的固体碳酸化反应从烟道气中分离出来。通过对不同测试条件下连续PIM-1模块性能的定量比较评估，提出了大规模利用CO _2的可行途径。我们还确定了我们方法中难以克服的障碍，例如膜的稳定性和可能形成的水垢。两种并行研究流（CO ₂捕获和利用）的集成方法可以为大规模CCU提供可靠且具有成本效益的策略。
