In this perspective, we detail how solvent-based carbon capture integrated with conversion can be an important element in a net-zero emission economy. Carbon capture and utilization (CCU) is a promising approach for at-scale production of green CO-derived fuels, chemicals and materials. The challenge is that CO-derived materials and products have yet to reach market competitiveness because costs are significantly higher than those from conventional means. We present here the key to making CO-derived products more efficiently and cheaper, integration of solvent-based CO capture and conversion. We present the fundamentals and benefits of integration within a changing energy landscape (, CO from point source emissions transitioning to CO from the atmosphere), and how integration could lead to lower costs and higher efficiency, but more importantly how CO altered in solution can offer new reactive pathways to produce products that cannot be made today. We discuss how solvents are the key to integration, and how solvents can adapt to differing needs for capture, conversion and mineralisation in the near, intermediate and long term. We close with a brief outlook of this emerging field of study, and identify critical needs to achieve success, including establishing a green-premium for fuels, chemicals, and materials produced in this manner.
从这个角度来看，我们详细阐述了与转化相结合的溶剂基碳捕集如何能够成为净零排放经济中的一个重要元素。碳捕集与利用（CCU）是大规模生产绿色一氧化碳衍生燃料、化学品和材料的一种有前景的方法。挑战在于，一氧化碳衍生的材料和产品尚未达到市场竞争力，因为成本显著高于传统方法的成本。我们在此介绍使一氧化碳衍生产品更高效、更便宜的关键，即溶剂基一氧化碳捕集与转化的整合。我们阐述了在不断变化的能源格局（从点源排放的一氧化碳向大气中的一氧化碳转变）中整合的基本原理和益处，以及整合如何能够降低成本、提高效率，但更重要的是，溶液中改变后的一氧化碳如何能够提供新的反应途径来生产目前无法制造的产品。我们讨论了溶剂如何成为整合的关键，以及溶剂如何能够在短期、中期和长期适应捕集、转化和矿化的不同需求。我们最后简要展望了这个新兴的研究领域，并确定了取得成功的关键需求，包括为以这种方式生产的燃料、化学品和材料确立绿色溢价。
