The approach of incorporating life cycle assessments alongside techno-economic evaluations presents a comprehensive understanding of the sustainability of e-fuels . This approach is crucial to guarantee that the long-term environmental outcomes are in harmony with the initial economic estimations . Advancements in processes such as high-temperature electrolysis and the reverse water-gas shift (RWGS) reaction, as observed by are crucial. These technologies exhibit high carbon conversion efficiency, but their economic viability remains heavily contingent on their scale of operation and future technological enhancements .
