See how Royal Dutch Shell produces sustainable renewable diesel in a joint venture called Diamond Green Diesel.
Diamond Green Diesel receives animal fat and used cooking oil primarily from restaurants, supermarkets and other foodservice establishments and inedible corn oil primarily from ethanol plants. Feedstocks can enter the plant through rail, truck or ships and barges.
The feedstocks are treated to remove impurities and then they are hydro treated with high-pressure hydrogen to remove oxygen and separate the water. The next step is isomerization where cold flow properties are managed to ensure compatibility with existing infrastructure and engines. The final step is fractionation, the separation into finished products.
Renewable diesel is stored until it is shipped to our customers primarily in low-carbon markets such as California, Canada and Europe. It can be transported via pipeline, ship or railcar.
Renewable diesel is a true hydrocarbon, like ultra-low sulfur diesel, gasoline, or crude oil, and can be used anywhere those fuels can be used without modifications to the engines or pipelines.
Renewable diesel has an energy density value equivalent to ultra-low sulfur diesel (ULSD), which is a cleaner-burning, lower-emission fuel than regular diesel.
Our low-carbon renewable diesel reduces the life cycle greenhouse gas emissions up to 80%, compared with traditional diesel.
The used cooking oil and inedible corn oil are treated to remove impurities.
Fat is collected from supermarkets, butchers, meat processors and other foodservice establishments.
Used cooking oil from restaurants, supermarkets and other food service establishments and inedible corn oil from ethanol plants.
Renewable diesel can be distributed using the established petroleum logistics system.
