Ediesel

E-diesel, also written eDiesel, is a term used to describe diesel fuel produced from electricity, typically renewable energy, rather than from crude oil. The fuel is generated via power-to-liquid pathways that combine hydrogen produced by electrolysis with captured carbon dioxide or other carbon sources to yield hydrocarbon fuels in the diesel range.

Common production routes include Fischer–Tropsch synthesis or methanol-to-diesel processes, using green hydrogen and a CO2 source. The resulting hydrocarbon liquids are designed to be drop-in replacements, compatible with existing diesel engines and fuel infrastructure without major modifications.

Lifecycle emissions depend on the electricity's carbon intensity and the CO2 source. When powered by low-emission electricity and sources of CO2 with minimal additional emissions, e-diesel can offer lower lifecycle greenhouse gas emissions than fossil diesel and can help decarbonize transport sectors where electrification is challenging.

Challenges include high production costs, energy losses in conversion steps, and the need for scalable, low-carbon hydrogen and carbon capture. Widespread adoption relies on policy support, investment in dedicated e-diesel plants, and rigorous fuel certification to ensure performance and safety.
