In the farmdoc daily article of July 12, 2017, we calculated the likely size of the "gaps" in biofuels consumption created by the EPA implementation of the Renewable Fuels Standards (RFS) for the years 2014 through 2018. The conventional ethanol gap is the difference between the (implied) conventional mandate and ethanol consumption, whereas the advanced mandate gap is approximately equal to the difference between the total advanced mandate and biomass-based diesel mandate. In this article, we estimate the total annual supply of biomass-based diesel (BBD) and then compare that to the size of the estimated mandate gaps plus the BBD mandate for each year from 2014 through 2017. Given that BBD has been the "marginal gallon" for filling the gaps in the RFS in recent years, this will provide important information on the total production and consumption requirements for BBD.
