According to Biodiesel Magazine, the EIA expects biodiesel production to grow 7%, averaging 114.000 b/d and as much as 115.000 b/d in 2023.

Both biodiesel and renewable diesel are made from vegetable and/or animal fats, but the difference comes from the fact that renewable diesel can be used as a complete diesel replacement, unlike biodiesel, which must be mixed with regular diesel in order to be useable.

This is due to the fact that renewable diesel is being processed the same way as regular diesel is.

Renewable diesel is hydrogenated, much like regular diesel, which means that it is combined with hydrogen, which gives it the benefit of being useable as a standalone replacement for the traditional fossil fuel, but it also means that it burns cleaner compared to biodiesel.

At the end of 2020, renewable diesel production in the USA was estimated to be about 2.2 billion liters and by 2024, the number is expected to reach 19.3 billion.

This makes companies like Renewable Energy Group find new sources for the required feedstock that will enable the further production of renewable diesel.

A few companies, camelina, CoverCress and carinata are looking to increase the growth of oilseed crops in order to try and satisfy demands for the resource that will allow the production of higher amounts of renewable fuels.

Still, despite the advantages presented by renewable diesel, biodiesel is here to stay for now, as Hermann Stockinger, chief sales officer of BDI Bio-Energy International, says that "we see that biodiesel shows the best greenhouse gas savings—with the right technologies, it allows use of the lowest-quality waste materials that can’t be used for renewable diesel."

The transport industry should make use of both renewable fuel solutions in order to reduce reliance on traditional diesel and, in the process, reduce greenhouse gas emissions.
