Green Car Congress

E-fuels are made by combining green hydrogen with CO 2 to produce liquid fuel that can be similar to gasoline or diesel used in conventional engines (as well as kerosene used in aviation). However, said T&E, particle pollution was far from eliminated. pollution. The three blends were: 100% paraffinic e-fuel. aromatics).
