T&E: tests show cars powered by electrofuels emit high levels of criteria pollutants

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). The three blends were: 100% paraffinic e-fuel. Aromatics may be added to e-fuels to improve combustion properties. aromatics).
