Ranking the Future: Carbon Capture Pathways That Actually Work

In this AI-generated episode of The Zero Emission Zone, we explore a cutting-edge study that evaluates the most promising carbon capture and utilization (CCU) processes using a new Sustainable Feasibility Index (SFI). The researchers rigorously model and assess eleven CCU pathways—like acetic acid, formic acid, and calcium formate—based on environmental, economic, and market factors. Tune in to find out which technologies are truly viable for a net-zero future. https://doi.org/10.1016/j.rser.2025.115331 [https://doi.org/10.1016/j.rser.2025.115331]
