Hydrogenation-Derived Renewable Diesel (HDRD)


A Renewable Fuel

HDRD is considered a ‘second-generation biodiesel’ because it refines fats and vegetable oils in an oil refinery. It’s still in the developmental stage and currently is not widely available.


Production

HDRD is produced by using a standard oil refinery to refine fats and vegetable oils into a diesel fuel, either by themselves or blended with oil.


CO₂ Emissions

Zero Net
Provided the production process uses feedstocks, the only CO2 released during HDRD combustion will be the CO2 originally absorbed by the biological material (plants etc) during its development.


Fuel Blends

Yes.
Ideally, HDRD will be used alone or blended with other diesels.


Infrastructure

In Place.
It can use the existing pipelines, stations and road transport systems for conventional diesel.


Compared to Diesel

It should allow for better performance and fuel economy, and lower emissions.


Advantages

• Its ultra-low sulfur content will reduce emissions
• Its high cetane number (diesel’s combustion quality) suggests improved vehicle performance and fuel economy.
• In addition to the fuel infrastructure, HDRD benefits from being able to use the current refinery infrastructure as well.


The Future…

… is unknown, although a number of oil companies in the US, Ireland, Finald, Brazil, and Italy currently have HDRD projects under development using a variety of processes.
