Sustainable Transport Energy: From Waste & CO₂ to Drop‑In Fuels and Cleaner Engines

How do we cut transport emissions while keeping today’s vehicles moving? This session surveys practical pathways across the fuel and engine ecosystem. Speakers will explore how wastes and byproducts can be converted into drop‑in liquid fuels and hydrogen‑rich streams, what techno‑economic and process choices matter for scale‑up, and how CO₂ can be transformed into useful intermediates with emerging electro‑, photo‑ and thermally driven methods. We’ll also look at the last mile—how fuel chemistry influences engine components and emissions control, informing durability and cleaner operation. Designed for researchers, engineers, and decision‑makers, the session connects feedstock → process → fuel slate → performance and highlights actionable levers to lower carbon intensity, improve infrastructure compatibility, and accelerate adoption in real fleets.
