Shedding light on the stakeholders’ perspectives for carbon capture

ChemRxiv

June 2023

Large-scale carbon capture technologies are crucial in the urgent quest to reduce CO₂ emissions. However, finding the most effective approach involves multiple stakeholders and complex considerations. Typically, research in this field has followed a sequential pattern, with chemists developing materials and engineers subsequently designing processes. The ultimate combination of these materials and processes has significant economic and environmental consequences.

To gain a comprehensive understanding of these impacts, this study presents the PrISMa (Process-Informed design of tailor-made Sorbent Materials) platform which seamlessly connects materials, process design, techno-economic analysis, and life-cycle assessment. Through the examination of over sixty case studies in which CO₂ is captured from different sources in various regions and with different technologies, this platform assists all stakeholders in identifying cost-effective technologies, optimal process configurations, and the molecular characteristics of top-performing materials. It also aids in determining the best locations for implementation and assessing environmental impacts, co-benefits, and trade-offs. By bringing together stakeholders early in the research process, this platform accelerates innovation precisely when it is most critical.
