More renewable diesel production than biodiesel production in U.S.


The federal government reports the nation’s production of renewable diesel fuel surpassed biodiesel production for the first time since 2011.

The U.S. Energy Information Administration, in its January 2023 Petroleum Supply Monthly stated that renewable diesel production in November 2022 averaged 113,000 barrels per day (b/d), a 38,000 b/d (51%) increase from November 2021 and a 74,000 b/d (191%) increase from November 2020.

The EIA forecast renewable diesel production to continue to grow and remain higher than biodiesel production, which we forecast to decrease.

U.S. biodiesel and renewable diesel production (January 2011-November 2022)


Renewable diesel is chemically equivalent to petroleum diesel but is produced using fats, oils, or greases rather than petroleum. Traditional diesel trucks can consume renewable diesel on its own or blended with petroleum diesel or biodiesel. Renewable diesel can also be transported through the same pipelines as petroleum diesel.

Biodiesel is produced with the same feedstocks as renewable diesel but is typically blended with petroleum diesel at concentrations of 20% or less for vehicle consumption. Biodiesel and renewable diesel are used to comply with the biomass-based diesel renewable volume obligations in the Renewable Fuel Standard (RFS) administered by the U.S. Environmental Protection Agency (EPA). They also supply 95% or more of the RFS requirement for non-cellulosic advanced biofuels.

What’s behind the growth of renewable diesel production?

Renewable diesel has been increasingly used to meet California’s Low Carbon Fuel Standard (LCFS), Oregon’s Clean Fuels Program, and the RFS. It will also help meet the requirements of Washington State’s Clean Fuels Program, which launched on January 1, 2023. In addition to these government programs, biomass-based diesel tax credits, which the Inflation Reduction Act of 2022 extended through 2024, have made production of renewable diesel more economical.

These programs have provided incentive to build new renewable diesel plants, including Diamond Green Diesel’s plant in Port Arthur, Texas, and several plants at sites of former petroleum refineries, such as Marathon Petroleum’s Dickinson, North Dakota refineryPhillips 66’s Rodeo, California refinery; and HF Sinclair’s Cheyenne, Wyoming refinery.

The EIA in its February Short-Term Energy Outlook (STEO),  forecast that renewable diesel production will continue growing (Figure 2) as production capacity increases. The agency estimates that renewable diesel production in 2022 averaged 97,000 b/d, an increase of 41,000 b/d (73%) from 2021.

It also forecast that renewable diesel production will average 148,000 b/d in 2023, an increase of 50,000 b/d (52%) from 2022, and 211,000 b/d in 2024, an increase of 63,000 (42%) from the forecast for 2023. The forecast shows renewable diesel production reaching 177,000 b/d at the end of 2023 and 252,000 b/d at the end of 2024.

Despite this growth, the EIA forecast U.S. renewable diesel production to remain well below the 357,000 b/d of planned production capacity shown for 2024 in the February 2 Today in Energy article for three reasons:

  • The significant ramp-up in production capacity will likely increase feedstock prices, which would make renewable diesel production less profitable and could decrease plant utilization or result in some canceled planned capacity.
  • Some planned capacity may come online later than planned.
  • New plants will take several months before producing at full capacity.

Because biodiesel producers compete for the same constrained feedstocks as renewable diesel producers, the EIA said it expects U.S. biodiesel production to decrease as renewable diesel production increases (Figure 3). Biodiesel production generates fewer RIN credits per gallon than renewable diesel, and biodiesel is primarily transported by rail and truck, which are more expensive than pipeline transportation.
