What is Renewable Diesel?

Commonly referred to as R100/R99 or hydrotreated vegetable oil (HVO), the use of renewable diesel can support customers as they continue to take steps toward their Due to its similar chemical structure, renewable diesel is a sustainable fuel that can directly replace traditional petroleum diesel. Made from recycled vegetable oils, tallow, or used cooking oil, it marks a significant advancement in eco-friendly fuel technology.

Renewable diesel is produced through a hydrotreating process, where fats, oils, and agricultural waste are reacted under high pressure and temperature in the presence of a hydrogen catalyst. 

This process results in a cleaner-burning fuel that works seamlessly in existing S13 diesel engines while significantly reducing carbon emissions.

Renewable Diesel Differs from Biodiesel

Unlike biodiesel, R100 is a paraffinic fuel that does not have any oxygen compounds in it. This allows the fuel to have better cold flow properties than biodiesel. In addition, its high Cetane number allows for a cleaner burn, making it a high-quality, low-carbon alternative to conventional diesel.

"Renewable diesel fuel meets the ASTM D975 Diesel Fuel Specification or the EN 15940 Paraffinic Diesel Fuel Specification, has better storage capabilities than biodiesel, and contains less sulfur and ash than petroleum-based diesel fuel which contribute to its lower tailpipe emissions and can be used by fleets as a tool to reach their sustainability goals," added Michael Noonan, vice president of Engineering, International.
