Energy fact of the week: Peak ethanol?

A few weeks ago, we noted here the sharp decline in biodiesel production during a one-year hiatus in the blending tax credit—more evidence of how biofuel production is dependent on government subsidies to grow. The Wall Street Journal reports today that the game may be up for corn ethanol, too. Now that Congress has cut $6 billion in annual subsidies for ethanol, growth in ethanol production is noticeably stalling. Between 2005 and 2011, ethanol production grew from 3.8 billion gallons to 13.9 billion gallons, but looks to be topping out.

However, the ethanol industry is lobbying the Environmental Protection Agency to increase the amount of ethanol used in the fuel supply from 10 to 15 percent, with a mandate for gas stations to offer E85. As the Journal story reports:

In several steps in the past year and a half, the Environmental Protection Agency has effectively increased the cap to allow gasoline that is 15% ethanol, known as E15. The ethanol industry is pinning its hopes on rapid adoption of E15. “We are putting a lot of faith in E15,” said Walter Wendland, CEO of two ethanol plants in northern Iowa. “We have a market problem out there for our production.”

Very revealing, that last phrase. But as the Journal continues:

But large-scale adoption of E15 faces sizable challenges. Not a single fuel station sells it today. Gasoline stations need to spend money changing pumps and alerting customers. The auto and oil industries have voiced strong concerns about E15, saying the fuel could damage cars and leave customers with expensive repairs.

Figure 2 shows the latest Department of Energy projections for ethanol use in gasoline and in E85, showing that continued growth in ethanol will almost all come in E85, if it comes anywhere at all. Blending of 10 percent ethanol in gasoline is only expected to grow at an annual rate of 0.8 percent through 2035, while E85 ethanol use is expected to grow at an annual rate of 27.5 percent. The power of mandates.

  1. GOOGLE: Prop 87 (510) 537-1796

    Bill Clinton, Al Gore & Senator Obama supported the California 2006 Prop. 87, a GMO corn ethanol welfare program.

    Bill, Al, have changed opinion on the ethanol mandate, I wonder if Obama will make this the time for CHANGE?

    I support a waiver of the ethanol mandate, voluntary use of ethanol in my gas.

    Federal ethanol policy increases Government motors oil use and Big oil profit.

    It is reported that today California is using Brazil sugar cane ethanol at $0.16 per gal increase over using GMO corn fuel ethanol. In this game the cars and trucks get to pay and Big oil profits are the result that may be ready for change.

    We do NOT support AB 523 or SB 1396 unless the ethanol mandate is changed to voluntary ethanol in our gas.

    Folks that pay more at the pump for less from Cars, trucks, food, water & air need better, it is time.

    The car tax of AB 118 Nunez is just a simple Big oil welfare program, AAA questioned the policy and some folks still agree.

    AB 523 & SB 1326 are just a short put (waiver) from better results.
