Renewable identification number prices for ethanol and biomass-based diesel remain high

The prices of renewable identification number (RIN) credits—a compliance mechanism used for the Renewable Fuel Standard (RFS) program administered by the U.S. Environmental Protection Agency (EPA)—have remained high in 2022. So far this year, RINs generated by biomass-based diesel (biodiesel and renewable diesel) production, known as D4 RINs, peaked on April 28 at $1.91 per gallon (gal), and RINs generated by ethanol production (D6 RINs) peaked on June 7 at $1.68/gal, close to the high prices seen in 2021.
