Domestic Fuel

While ILUC assumptions, data and methods may be greatly flawed, there is one comment I never see leveled and this comment has been proven without a doubt. Life cycle CO2 emissions are based as a percentage improvement on gasoline. The calculations end with BTUs in the tank. Ethanol has the capacity for thermal efficiencies of diesel when used in appropriate IC engines. Such a life cycle will reduce CO2 calculated emissions by a factor of about 1.7. Even slightly modified legacy vehicles get significantly increased thermal efficencies when run on E30. This life cycle is not a real life cycle, just one when ethanol is poluted with too much gasoline. When these real efficiency potentials of ethanol are ignored, one wonders if the ‘researchers’ are just drinking ethanol rather than really studying its positive potential.
