Retrofitting Low Carbon Aviation Fuels Processes From Natural Gas to Renewables Energy‐Based Systems

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT The aviation sector's dependence on high‐energy‐density fuels presents a challenge for decarbonization. This study evaluates the economic and environmental feasibility of retrofitting a gas‐to‐liquid (GTL) plant for low carbon aviation fuel (LCAF) production using solar electrification, an advanced reformer unit (CARGEN), and a hybrid ...
