Life Cycle Assessment (LCA) methodology is employed to assess the environmental impacts associated with each DACCU pathway. The analysis covers energy requirements, greenhouse gas emissions, and potential environmental tradeoffs, offering a holistic perspective on the sustainability of each process. Additionally, detailed costing information is presented to better understand the economic feasibility and market competitiveness of these technologies.
Mixed-integer linear programming model is used to investigate future pathways for direct air capture and CO2utilization with a focus on costs and carbon reduction. The system is optimized on the whole supply chain costs and on a number of environmental objectives using the U.S. as an example.
The outcomes of this study provide valuable insights for a wide range of stakeholders, including industry leaders and policymakers. It emphasizes the importance of advanced DACCU pathways in addressing climate change, supported by thorough LCA results, cost analyses, and optimization strategies. This comprehensive approach brings to the forefront the need for more sustainable and economically viable carbon capture and utilization practices.
