Ethanol’s future may hinge more on hybrids than EVs — and new tax credit changes could shake up the entire renewable fuels landscape.

In episode 205 of the CropWatch Podcast, Dr. Scott Irwin, Lawrence J. Norton Chair of Agricultural Marketing at the University of Illinois, shares insights on the clean fuel production credit (45Z) and the renewable fuels sector. He explains how recent tax credit changes in the Trump administration’s One Big Beautiful Bill (OBBB) could boost ethanol producers while disadvantaging sustainable aviation fuel (SAF), why ethanol might see a short-term resurgence, and why hybrid vehicles could pose a greater threat to ethanol than fully electric cars in the coming years. The episode wraps up with a discussion on carbon intensity scores and why, despite seeming logical in theory, indirect land use charges tied to CI scores can be unfair in practice.
