Reviewing the Challenges Toward Sustainable and Carbon‐Neutral E‐Fuels

Abstract Decarbonizing transportation, especially aviation, shipping, and trucking, is challenging. E‐fuels offer a solution by using renewable electricity to produce carbon‐neutral fuels compatible with current engines and infrastructure. Created from hydrogen via electrolysis and CO 2 from the atmosphere or industrial processes, e‐fuels mimic conventional fuels, allowing use without major modifications. Key processes include hydrogen generation, CO 2 capture, and synthesis. This study consolidates knowledge, addresses research gaps, and aims to stimulate innovation.
