Turning corn ethanol waste into a new domestic source of jet fuel

Abstract: The world is not running out of demand for jet fuel, it is running out of secure, affordable sources of it. Europe's current crisis, with reserves reportedly down to days of supply, has exposed what energy analysts have long warned: aviation runs on a fragile, foreign-controlled fuel chain with no meaningful alternative. Sustainable Aviation Fuel was supposed to close that gap, yet today meets less than 1% of global demand, not because the technology doesn't exist, but because most SAF pathways compete for the same scarce, expensive feedstocks that created the problem in the first place. EcoGrains is building something different: a genuinely new domestic source of jet fuel. We convert contaminated distillers' grains, a corn ethanol co-product that cannot enter the food supply and is currently discarded, into drop-in SAF using patented microbial fermentation technology licensed from Sandia National Laboratories. By starting with higher-carbon fusel alcohols rather than conventional ethanol, our process requires fewer upgrading steps to reach jet fuel range, improving efficiency and cutting production costs. The output is chemically identical to Jet A, no new infrastructure, no regulatory barriers, no airline resistance. Backed by $3M+ in DOE funding alongside Lawrence Berkeley National Laboratory and Sandia, EcoGrains is building a distributed, domestically-sourced SAF supply chain that no competitor has commercialized, and that no geopolitical disruption can shut down.
