This study undertakes a methodical evaluation of TEA and LCAs pertaining to the generation of e-fuels, via hydrogen, biomass flue and atmospheric carbon dioxide through electrolysis and direct air capture (DAC). We meticulously adhered to the bibliometric method, a quantitative method used to analyse and evaluate scholarly literature, including publicly accessible scientific publications, articles, journals, and other types of academic content. The goal of bibliometrics is to assess the impact, influence, and relationships within the academic literature. This method relies on statistical and mathematical analyses to derive meaningful insights from patterns and trends in published works that includes the formulation of a precise search string, This review article aims to systematically collate data including keywords, abstracts, and titles from pertinent journal articles and global conference proceedings spanning a decade from 2013 to 2023. The database was guided by a carefully curated set of keywords: ("techno-economic analysis" OR "techno-economic assessment") AND ("life cycle analysis" OR "life cycle assessment") AND (e-fuel OR liquid hydrocarbon) AND (synthetic fuel OR sustainable aviation fuel). These keywords were feature engineered after reviewing multiple papers and journal articles that focused on the techno-economic and life cycle assessments of e-fuel production using hydrogen and atmospheric carbon dioxide. To uphold the integrity of our bibliometric method, only peer-reviewed journal articles, publicly accessible technical reports, and relevant conference papers published in academic journals were considered.
