Hydrotreated vegetable oil

Hydrotreated vegetable oil (HVO) is a biofuel made by the hydrocracking or hydrogenation of vegetable oil or animal fat. Hydrocracking breaks big molecules into smaller ones using hydrogen while hydrogenation eliminates double bonds by adding hydrogen to the molecules. These methods can be used to create substitutes for gasoline, diesel, propane, kerosene and other chemical feedstock. Diesel fuel produced from these sources is sometimes referred to as green diesel or renewable diesel.

Diesel fuel created by hydrotreating is distinct from the biodiesel made through esterification.
