Absolute Sustainability Assessment of Flue Gas Valorization to Ammonia and Synthetic Natural Gas.

ABSTRACT: Carbon capture and utilization has gained attention to potentially curb CO₂ emissions while generating valuable chemicals. These technologies will coexist with fossil analogs, creating synergies to leverage circular economy principles. In this context, flue gas valorization from power plants can assist in the transition. Here, we assessed the absolute sustainability of a simulated integrated facility producing ammonia and synthetic natural gas from flue gas from a combined-cycle natural gas power plant based in Germany, using hydrogen from three water electrolysis technologies (proton exchange membrane, alkaline, and solid oxide cells), nitrogen, and CO₂. For the first time, we applied the planetary boundaries (PBs) framework to a circular integrated system, evaluatin
