The Nebraska Ethanol Board (NEB) this week announced the publication of the interim report for Phase II of the state’s E30 Demonstration.

The project is demonstrating the viability of E30 fuel (a blend of 30% ethanol and 70% gasoline) in non-flex fuel vehicles. Phase I was conducted in 2019, and the ongoing Phase II began in 2023. So far, the 94 State of Nebraska light-duty vehicles involved in Phase II have collectively driven more than 215,000 miles on E30 fuel. The research team, from the University of Nebraska-Lincoln, has found further evidence of the conclusions from Phase I: E30 is safe and effective for non-flex fuel vehicles, and E30 is economically viable for broader consumption.

“The results in the interim report are very encouraging,” NEB Executive Director Ben Rhodes said. “While we’re not surprised to learn that non-flex fuel engines can safely utilize E30, it’s still exciting to see the data demonstrate that fact. Plus, the report makes it clear that E30 is far cheaper than E10, which we know is thanks to the inclusion of more ethanol. This price advantage comes with a fuel economy gain for some vehicles on E30 compared to E10—a groundbreaking result—or only a very small reduction that is more than covered by the cost difference. These are all strong signs that mid-level ethanol blends like E30 are a prime long-term option for the world’s transportation energy needs.”
