英国赫瑞瓦特大学Garcia, Susana团队报道了一个加速吸附剂碳捕获的整体平台。相关研究成果发表在2024年7月17日出版的国际知名学术期刊《自然》。

减少二氧化碳排放迫切需要大规模部署碳捕获技术。这些技术必须将二氧化碳从各种来源中分离出来，并将其输送到不同的反应池中。寻求特定源-池对的最佳解决方案是一项复杂的多目标挑战，涉及多个利益相关者，取决于社会、经济和区域背景。目前，研究遵循顺序方法：化学家专注于材料设计，工程师专注于优化工艺，然后以影响经济和环境的规模进行运行。评估这些影响，如工厂生命周期内的温室气体排放，通常是最后一步。

该文中，研究人员介绍PrISMa（定制吸附材料的过程知情设计）平台，该平台集成了材料、工艺设计、技术经济和生命周期评估。研究人员比较了使用不同技术从全球5个地区的各种来源捕获二氧化碳的60多个案例研究。该平台同时向各利益相关者通报技术、工艺配置和位置的成本效益，揭示性能最佳的吸附剂的分子特征，并提供有关环境影响、共同效益和权衡的见解。通过在早期研究阶段团结利益相关者，PrISMa在这一关键时期加快了碳捕获技术的发展，因为目标是实现净零排放世界。

Abstract: Reducing carbon dioxide (CO2) emissions urgently requires the large-scale deployment of carbon-capture technologies. These technologies must separate CO2 from various sources and deliver it to different sinks1,2. The quest for optimal solutions for specific source–sink pairs is a complex, multi-objective challenge involving multiple stakeholders and depends on social, economic and regional contexts. Currently, research follows a sequential approach: chemists focus on materials design3 and engineers on optimizing processes4,5, which are then operated at a scale that impacts the economy and the environment. Assessing these impacts, such as the greenhouse gas emissions over the plant’s lifetime, is typically one of the final steps6. Here we introduce the PrISMa (Process-Informed design of tailor-made Sorbent Materials) platform, which integrates materials, process design, techno-economics and life-cycle assessment. We compare more than 60 case studies capturing CO2 from various sources in 5 global regions using different technologies. The platform simultaneously informs various stakeholders about the cost-effectiveness of technologies, process configurations and locations, reveals the molecular characteristics of the top-performing sorbents, and provides insights on environmental impacts, co-benefits and trade-offs. By uniting stakeholders at an early research stage, PrISMa accelerates carbon-capture technology development during this critical period as we aim for a net-zero world.
