Biodiesel and HVO are biofuels produced from renewable resources such as vegetable oils, including soybean oil, canola oil, and palm oil, as well as used cooking oils and animal fats. While the resources may vary globally, finished fuel specifications are independent of the feedstock.
HVO and biodiesel are the two main renewable liquid fuels readily available for end users, but they have several differences:
|Biodiesel (FAME)||Hydrotreated Vegetable Oil (HVO) (Renewable Diesel)|
|Source||Vegetable oils and fats||Vegetable oils and fats|
|Product||Oxygenated, ester||Non-oxygenated, paraffin|
|Replacement for diesel?||Yes, with some cautions||Yes|
|Specifications||ASTM D6751, EN 14214, Cat Spec||EN 15940|
Biodiesel is registered with the U.S. Environmental Protection Agency (EPA) and is legal for use at any blend level in both highway and nonroad diesel engines. In the U.S., the applicable blending spec for B100 is ASTM D6751. B20 blend specs in the US is ASTM D7467.
European fuel standard EN 14214 ensures that biodiesel is suitable for even the most modern engines. EN 16709 describes B20 and B30 biodiesel blends.
HVO fuels must be per EU 15940 spec. HVO fuels also satisfy the diesel fuels specifications ASTM D975 and EN 590, except for density.
Only purchase biodiesel and HVO fuels from reputable dealers selling commercial grade biodiesel.
