U.S. Department of Agriculture Secretary Tom Vilsack has recently expressed his support for raising the amount of ethanol into the fuel mix to a percentage higher than the current 10%.
“An increase in the percentage that can go into gasoline would be a way to stimulate the corn-based ethanol industry,” Vilsack said.
Vilsack has reportedly been speaking with U.S. Environmental Protection Agency Administrator Lisa Jackson and encouraging her to make an adjustment to the blend ratio.
“My hope is that we can get a blend rate that is higher than 10%,” Vilsack said. “That is going to create more opportunities for the ethanol industry.We’re encouraging EPA to do that. We hope that they’ll listen to our concerns.”
Although Vilsack is not quite sure what the blend cap should be yet, he still strongly supports this increase because he believes it will “create more opportunities for the ethanol industry.”
Let’s raise those percentages!
Neal St. Anthony, columnist for the Minneapolis Star-Tribune, has written a story about the recent University
of Minnesota study, and a contradictory study from the University of Nebraska released earlier this week.
The University of Nebraska research reveals that the latest crop of efficient corn-ethanol refineries has helped cut greenhouse gas emissions to half that of gasoline and the industry now is producing up to 1.8 units of energy through ethanol for every unit of energy used to produce it. That’s quite a leap in efficiency for an industry that early on had efficiency ratios that barely exceeded 1 to 1.
So why the huge discrepancies in the findings of each report?
In short, the Nebraska researchers found that claims of ethanol inferiority were rooted in corn-production statistics, ethanol plant performance and byproduct use that dates back years. By the end of 2009, Cassman said, newer and renovated plants will account for 75 percent of ethanol production. They increasingly use alternative fuels, are more productive and efficient and are located close to livestock for efficient use of the residual distillers grains as feed.
Additionally, St. Anthony hits the nail on the head when it comes to the bottom line:
To wit: The dirtiest and most expensive fuel, particularly when you add in related defense spending, is oil, two-thirds of which we import at a cost of something like $400 billion annually. The money goes to mostly government-owned monopolies, and some of those countries are hostile to the United States.

This edition of “The Ethanol Report” features comments from Renewable Fuels Association Vice President of Research and Analysis Geoff Cooper about recently released studies from the University of Nebraska and the University of Minnesota regarding life cycle analysis and greenhouse gas emissions of ethanol compared to gasoline. Cooper compares the two reports and discusses RFA’s major concerns with the Minnesota study.

Van Buren, Michigan based company Ricardo, Inc. has announced that they have supposedly developed “technology that optimizes ethanol-fueled engines to a level of performance that exceeds gasoline engine efficiency“.
The technology, called Ethanol Boosted Direct Injection or EBDI, takes full advantage of ethanol’s best properties — higher octane and higher heat of vaporization — to create a truly renewable fuel scenario that is independent of the cost of oil.
Ricardo’s President Dean Harlow is optimistic about applying “theoretical discussions” to find real world solutions when it comes to renewable fuel.
EBDI solves many of the challenges faced by flex-fuel engines because it is optimized for both alternative fuels and gasoline. Current flex-fuel engines pay a fuel economy penalty of about 30 percent compared to gasoline when operated on ethanol blends such as E85. The EBDI engine substantially improves ethanol’s efficiency, and performs at a level comparable to a diesel engine.
The prototype EBDI is a 3.2-liter V6 engine that ultimately could serve as a replacement for a large gasoline or turbo-diesel engine in a large SUV. The first firing of the engine & initial development is currently taking place and will be installed into a dual-wheel pick-up truck demonstration vehicle later this year.
We’re definitely looking forward to the demonstration vehicle Ricardo promises. Keep an eye out for this new technology.
Two different university studies in the past few weeks have come to two completely different conclusions regarding the greenhouse gas emissions of corn ethanol, which clearly proves there is no scientific consensus on this issue.

The first study, by the University of Nebraska, concluded that “recent improvements in crop production, biorefinery operation, and coproduct utilization in U.S. corn-ethanol systems result in greater GHG emissions reduction, energy efficiency, and ethanol-to-petroleum output/input ratios compared to previous studies. Direct-effect GHG emissions reductions were found to be 48% to 59% compared to gasoline, which is two to three times greater than estimated in previous reports.”
The second study, just released last week by the University of Minnesota, comes up with a conclusion that only a rocket scientist could decipher. “If C is valued at $120 Mg_1, the societal climate-change cost from production and consumption of gasoline is $0.10 L_1 ($0.37 gal_1), between $0.08–$0.14 L_1 ($0.31 and $0.52 gal_1) for corn ethanol, but only between $0.01–$0.02 L_1 ($0.03 and $0.09 gal_1) for cellulosic ethanol.”
Unfortunately, the UMN study is getting lots of media attention because the sound bite is that corn ethanol “can be as harmful to the environment as gasoline, and that the combined costs to climate-change and health exceed that of gas.”
That simplistic conclusion is based only on certain hypotheses, including the baseless assumption that additional corn demand for increased ethanol production will cause conversion of large amounts of grassland enrolled in the Conservation Reserve Program.
The paper itself states that if the authors’ assumed land use change emissions are removed from the analysis, average corn ethanol reduces greenhouse gases by 30% compared to gasoline and advanced corn ethanol reduces GHGs by 46%. According to the report, “Whether corn ethanol has lower life-cycle GHG emissions than gasoline depends on biorefinery heat source, assumptions about technology, and land-use change.”
In other words, the authors of the UMN study considered several different land use scenarios and process heat sources, and came up with DIFFERENT CONCLUSIONS. The headlines come from the worst possible scenario which assumes all corn ethanol is produced in one way and relies on debatable methodologies for which no scientific consensus exists, including land use change and carbon social cost.
The sad thing is that journalists get blinded by all this junk science and report whatever translates into a simple sound bite. It is imperative that the industry constructively engage in this issue to insist that it is driven only by sound science.
