The Biden administration has laid out rules for corn farmers to qualify for subsidies to supply feedstock for sustainable aviation fuel (SAF). The corn is now used to make ethanol, which is added to gasoline, but the move to electric cars will diminish that market. Ethanol can be turned into Jet A, however, and will cut the carbon footprint of jet fuel. The administration is proposing subsidies from $1.25 to $1.75 a gallon for farmers but only if they meet some conditions.
