Cloudy skies ahead for ethanol

On Dec. 31, 2011, the 45 cent per gallon federal “blender credit” for ethanol finally ended with little fanfare, as described in this article from U.S. News.

Since fuel producers are still required to meet the RFS ethanol mandates in EISA 2007, the end to the credits will have no effect on the continued adulteration of our nation’s gasoline supply that also renders much of gasoline useless as an aviation fuel.

If an end to taxpayer subsidies was not hard enough on ethanol producers and distributors, the latest trends in the overall sale of gasoline must be especially foreboding. As seen in this chart from the DOE’s EIA, monthly deliveries of gasoline have dropped by a whopping 50% in the past decade, and are the lowest they’ve been since the early 1980s. This means that demand for ethanol, despite federal mandates requiring its sale, have also dropped dramatically, as reported by the Des Moines Register, which reports than many ethanol producers are now operating at a loss or are closing facilities.

The next shoe to drop will likely be corn producers, who appear to be hoping for a return to high prices from last summer despite the drop in demand both domestically and overseas.

We have likely already hit the so-called “blending wall,” a situation where federal ethanol mandates cannot be achieved even when every drop of gasoline in the country contains 10% ethanol. Either the EPA and Congress must now ignore its own laws, or the RFS mandates must be modified. Hopefully, logic will prevail and our elected officials will rethink the entire law, either scrapping it outright and allowing free markets to determine what fuels are best, or at least to require premium ethanol-free fuel to be sold wherever an ethanol blend is sold, as Mississippi State Senator Michael Watson recently proposed.

  1. The chart referenced in the blog actually shows a decline in gas deliveries of about  a third, not 50% as quoted in the post.  Still a good thing, for sure.  The sooner a little rationality is injected into this government-mandated misadventure, the better.

  2. It’s about time we end this ethanol experiment. A few years back the National Geographics Magazine had an article on ethanol made from Corn in the USA taking 7 barrel of diesel to produce 8 barrels of ethanol, where in Brazil using sugar cane they produce 8 barrels for one barrel of deisel fuel.  Oil is used to make the fertilizers, run the tractors and haul the corn, then when the ethanol is made it has to be transported by train or tanker truck since the pipeline owners won’t let it in there line to polute and damage there equipment. Just on a BTU scale 7 barrel or diesel has more energy than 8 barrels of ethanol.  Ethanol eats aluminum, drys out natual rubber seals and is just bad for the environment.  With the surge of corn production in the midwest the Mississippi river has taken the runoff nitrates from the fertilized fields down to the Gulf of Mexico and created a large alge bloom that depleats the water of oxygen and kills off fish.   Since ethanol is more soluable in water than in gasoline if you have any water in your gas tank (which is a major problem in airplanes and boats, but can be a problem in cars as well) the ethanol will form a mixer with the water that is not able to burn and if your tank gets to empty will stall your engine (it’s good to have a water seperator to keep the water out of your fuel but will it handle water and ethanol mix).  End ethanol now, it was a bad idea and just another government gimick that didn’t work to say that it is a bio-fuel is proposerious.
