The commercial deployment of cost-effective carbon capture technology is hindered partially by the lack of a proper suite of materials-related measurements, standards, and data, which would provide critical information for the systematic design, evaluation, and performance of CO2 separation materials. Based on a literature search and conversations with the carbon capture community, we review the current status of measurements, standards, and data for the three major carbon capture materials in use today: solvents, solid sorbents, and membranes. We highlight current measurement, standards and data activities aimed to advance the development and use of carbon capture materials and major research needs that are critical to meet if innovation in carbon capture materials is to be achieved. The review reveals that although adsorbents are considered to have great potential to reduce carbon capture cost, there is no consensus on the experimental parameters to be used for evaluating sorbent properties. Another important finding is the lack of in situ experimental tools for the structural characterization of solid porous materials during CO2 adsorption, and computational methods that would enable a materials-by-design approach for their development.
商业部署具有成本效益的碳捕获技术部分受到缺乏适当的材料相关测量、标准和数据套件的阻碍，这些信息对于 CO2 分离材料的系统设计、评估和性能至关重要。基于文献检索和与碳捕获界的对话，我们回顾了当今使用的三种主要碳捕获材料（溶剂、固体吸附剂和膜）的测量、标准和数据的现状。我们重点介绍了旨在推进碳捕获材料开发和使用的当前测量、标准和数据活动，以及如果要实现碳捕获材料的创新，就必须满足的关键研究需求。该综述表明，尽管吸附剂被认为具有降低碳捕获成本的巨大潜力，但对于评估吸附剂性能要使用的实验参数，尚无共识。另一个重要发现是，在 CO2 吸附过程中对固体多孔材料进行结构表征缺乏原位实验工具，以及能够为其开发采用材料设计方法的计算方法。
