Abstract

Considering the increasing concerns regarding climate change, a fundamental transformation in global energy policies is imperative, particularly within the aviation sector, which is historically anchored in the consumption of fossil fuels. This perspective presents a scholarly evaluation of the progression from deep-rooted fossil-fuel-dependent technologies to innovative strategies aimed at carbon neutrality, specifically focusing on the formulation of sustainable aviation fuel from CO2. An analytical review of the cutting-edge methodologies for CO2-to-jet fuel conversion is provided, and the practicality of current industrial models are assessed. This perspective explores the intricate consequences of adopting such groundbreaking technologies and evaluates their technical practicability, economic feasibility, and environmental advantages. The insights obtained from this study will substantially contribute to the discussion on energy sustainability, emphasizing the synergy between sophisticated CO2 conversion processes and the overarching goal of realizing global carbon neutrality.

Graphical Abstract

This work reviews some innovative approaches to achieving carbon neutrality in aviation by converting CO2 to sustainable aviation fuel (SAF), assessing the feasibility of current CO2-to-jet fuel conversion methodologies and their potential environmental and economic impacts.
