Optimization of cost-effectiveness and environmental impact in advanced membrane technologies for CO2 capture and utilization

This research presents a comprehensive comparative study on advanced membrane technologies for CO2 capture and utilization, focusing on optimizing cost-effectiveness and minimizing environmental impact. The study examines Polymer, Mixed-Matrix, and emerging membrane technologies, with a particular emphasis on Ionic Liquid Membranes and MOF-based Membranes. Ionic Liquid Membranes demonstrate superior CO2 permeability and selectivity, making them ideal for high-purity applications, while MOF-based Membranes offer a balanced performance suitable for diverse conditions. Polymer Membranes emerge as the most cost-effective option upfront; however, their long-term viability is challenged by higher operational costs. Mixed-Matrix Membranes display moderate environmental impact, which could be further reduced by optimizing their fabrication processes. Notably, Electrochemical Membranes exhibit the lowest CO2 emissions, underscoring their environmental advantage. The findings underscore the necessity of advancing Polymer and Mixed-Matrix Membranes by enhancing their economic viability and reducing their carbon footprint. This study provides valuable insights for developing next-generation membrane technologies that harmonize performance, cost, and sustainability, thereby paving the way for more efficient and environmentally friendly CO2 capture and utilization processes.
