The Fuel for Thought podcast by Topsoe explores the intricate science behind jet fuel emissions and their environmental impact, specifically focusing on sustainable aviation fuels (SAFs). The episode titled SAF Special #1 of 3: From Combustion to Contrails dives into how jet fuel combustion contributes to global warming by emitting CO2 and soot, leading to contrail formation. In this episode, host Sylvain is joined by Patrick LeClercq from the German Aerospace Center, where they discuss jet fuel composition and the advantages of SAFs, which reduce emissions by having lower aromatic content.
