E85 reaches western Canada
Vancouver, Canada-based Arcade Station has become the first filling station in the region to sell E85 fuel – an ethanol-petrol blend comprising 85% .ethanol. The site now sells regular and diesel fuel in addition to E85.

Will flex fuel save you money?
First the good news: Gasoline prices are at their lowest level in months, according to AAA. Now more good news. Flex-fuel prices have been falling, too, and are about $1 less per gallon than regular gasoline now, according to the Kiplinger Agriculture Letter.So maybe you’re scratching your head wondering what flex fuel is and why you should care that it’s cheaper than gas.
E85, or flex fuel, is a blend of 85 percent ethanol and 15 percent gasoline that can be used in vehicles specially designed to run on it as well as regular gasoline. There are more than 10.6 million flex-fuel vehicles on the road, according to the U.S. Energy Information Administration. You might even be driving one and not realize it.
The journey of a thousand miles, replacement fuels and FFVs
The headlines recently have been terrible — a commercial plane was shot down over the Ukraine, there’s war in the Middle East and more. It makes you wonder, over and over again, about man and woman’s inhumanity to his or her fellow men and women.
While certainly not equal in impact on the world at the present time, I happened to run across one point of light concerning a set of innovations which, in the long run, could positively impact climate change, security and consumer choice issues. It was reflected in a couple of articles describing the partnership between the state of California’s Energy Commission and Cummins Engines to develop an E85-fueled engine that apparently cuts Co2 by up to 80 percent (read it in Fleets and Fuels) in medium-duty trucks.
According to Cummins Engines and the Commission, a relatively small 4-cylinder, 2.8-liter engine has been successfully subjected to 1,000 miles and 1,500 hours of testing. It is now going through validation tests in Sacramento.
The story is a welcome one. Cummins indicates that the engine can generate 250 horsepower and 450 pound-foot of torque using E85. “Using lignocellulosic-derived E85, the powertrain’s efficiency features 75 to 80 percent lower well-to-wheels carbon emissions than gas engines; depending on the drive cycle…Cellulosic E85 is not derived from tilling, fertilizing and harvesting corn…Using corn-derived E85, the high thermal efficiency and power-to-weight ratio of this engine results in 50 to 80 percent lower well-to-wheels carbon emissions compared with the gasoline engine.”
Based on the Cummins documentation, California’s Energy Commission indicates “that successful completion of the project may result in a new market for E85 fuel now dominated by gasoline and diesel in the 19,500 lb. step-van fleet market.” The agency estimates greenhouse-gas savings as great as 69 percent, or 10 to 20 percent using corn based ethanol.
Fortunately, the general principles guiding development of Cummins’ engine may help improve flex-fuel automobiles and grant Americans more confidence in the environmental, price and economic benefits associated with extended use of E85.
Lessons learned may increase the nation’s ability to reduce GHG emissions. Based on what Cummins has done, using smaller engines extends the benefit of E85. Diesel-like cylinder pressures are important. Ethanol’s high-octane rating generates more engine efficiency. Use of state-of-the art sensors for spark ignition and coordination of stop-and-start functions enhances efficiency and reduces emissions. E85 is clearly a safe fuel.
The knowledge gained from the Cummins effort could lead to better flex-fuel vehicles and could support the effort to use increased technology fixes for older, non-flex-fuel cars and FFV twins. Perhaps the biggest benefit from the partnership between California and Cummings relates to the boost it could give to the search for replacement fuels, as well as the myth-busting understanding it could provide consumers about the safety of E85. It is a safe fuel, assuming engine adaptation and software amendment.
Elon Musk’s proposal to share Tesla’s electric-car patents and ideas might at least encourage increased collaboration among FFV makers in Detroit and the potential players in the conversion industry that likely would emerge, subsequent to EPA testing and approval of older vehicles for conversion. Even improved cooperation at the margin would could expand production of new FFV vehicles and expand conversion of older vehicles. For automakers and makers of conversion kits, as well as developers of FFV software technology, successful collaboration would generate larger markets.
Increased use of E85 through conversion of existing cars and the increased production of new FFV vehicles would help meet national and local environmental objectives, reduce gasoline prices and provide consumers with lower fuel costs, apart from gasoline. Both would also reduce dependency on foreign oil. Paraphrasing the poet Robert Frost, while FFVs — new or converted — are on a road less traveled now, as John F. Kennedy indicated, the journey of a thousand miles must begin with one step. The road less traveled now has more replacement-fuel drivers and FFVs than ever. Because of this fact, the journey of a thousand miles toward alternative fuel choices has made progress and, hopefully soon, will move at a faster speed. Success will mean a better quality of life for us all. It’s good news!

Attention Investors: Opportunity for an oil change
What would you say about an investment opportunity where your product is four times cheaper than the commodity it is trying to replace and there are 77 million potential customers waiting to use it?
Does that sound like something that you would like to put your money into? Well that’s the opportunity that awaits anyone willing to invest in the infrastructure and technical changes needed to substitute natural-gas-based ethanol for foreign-fuel-based gasoline in our cars.
A full-fledged prospectus was presented this month by Miles Light, professor at the Leeds School of Business at the University of Colorado Boulder, in a report called “Natural Gas Based Liquid Fuels: Potential Investment Opportunities in the United States,” written for the recent Goldman Sachs Energy Summit.
Professor Light lays out the situation in very clear terms: “Low natural gas prices and new technology present an opportunity to market and sell liquid fuels in the form of ethanol and methanol to U.S. consumers. Per unit of energy, oil is almost four times more expensive than natural gas. This implies a potential arbitrage opportunity to convert natural gas and natural gas liquids into a liquid fuel. In the U.S., 14.5 million vehicles can currently utilize ethanol fuels. These are the so-called ‘Flex Fuel’ vehicles. Another 16.1 million FFV ‘Twins’ can utilize ethanol with a software upgrade, and 46.9 million conventional fuel vehicles can potentially be converted for $150-$250 each. In all, this presents 77.75 million light duty vehicles, or 31.8% of the national light duty fleet, that would potentially purchase natural gas liquid fuel, if prices were attractive.”
You’ve undoubtedly heard the phrase, “If we can capture just 2 percent of this market…” Well, this is it. There are opportunities up and down the line, from auto mechanics performing flex-fuel conversions on conventional engines to major corporations building plants to convert natural gas to ethanol.
What Light is talking about here is the wholesale substitution of a portion of our natural gas resources for the oil we import in order to run our transportation sector. True, we’ve cut down on imports so they now make up less than half of our consumption for the first time since the early 1990s. But what people are missing is that we still pay the same amount for that oil because the price keeps rising. This continues to put a $380 billion dent in our trade balance every year — not to mention that much of this money goes to countries that actively support hostile actions against America and its friends and allies around the world.
So what would it take to make this transition? There’s certainly been a lot of activity to date. However, most of it has concentrated on utilizing compressed natural gas (CNG) and liquid natural gas (LNG). T. Boone Pickens’ Clean Energy Fuels is in the process of building a “CNG Highway” to service long-haul trucks from coast to coast. He’s already completed the first leg from Los Angeles to Houston. Those big 18-wheelers have room for the larger gas tanks and travel fixed routes along the Interstate Highway System that can be serviced by relatively few filling stations.
But passenger vehicles are a completely different matter. They travel everywhere and would require a whole new national infrastructure to fill their tanks. The auto companies have already offered a few CNG models but they haven’t sold well. It’s the chicken-and-egg problem — people won’t buy cars before the stations become common and the stations won’t be built until there are enough cars on the road.
With ethanol, however, there is already an infrastructure in place. The country is presently outfitted with 2,394 gas pumps dispensing E85, a mixture of 85% ethanol and 15% gasoline. (The gasoline is there just to start on cold mornings.) Most of these are concentrated in the farm belt but they’re starting to make their way into major cities on the East and West Coasts as well.
The point is this: these stations have been set up to handle corn ethanol. This is the result of the 35-year government effort to promote biofuels. But Light suggests that these stations could just as easily dispense ethanol made from natural gas. No new technology would be necessary, nor would it require any special permission from the government. (Methanol, which is a little easier to synthesize than ethanol, has a greater toxicity and would require some additional approval from the Environmental Protection Agency.)
So according to Light, this is where the investment opportunities lie. The conversion of natural gas to ethanol is the first and most important step, but Coskata, Inc. already has a working facility and Celanese Corporation is converting coal to ethanol in Indonesia. Light estimates that, at current and foreseeable prices, the return on investment could be as high as 46 percent.
Then there are all the intervening steps. “Alongside the core ethanol production opportunity, there are several related supply-chain developments projects, such as production facility development, ethanol fuel marketing, fueling station upgrades, blending facility expansions, and vehicle update kits,” he writes. All are well within the range of private investment. No government subsidies or mandates would be required.
In other words, the conversion of significant portions of our auto fleet to natural gas presents a whole world of opportunity just waiting for imaginative, ambitious investors to take advantage.

Let freedom ring: Oil companies, capitalism and fuel choice
It’s a free county, ain’t it? Americans have many choices that are denied to citizens of other less-fortunate nations. But we forget how many decisions are made for us, sometimes out of necessity, such as paying taxes; sometimes out of greed, such as the monopolistic actions of oil companies in denying many Americans the ability to purchase alcohol-based fuels at their corner gas station. Try it someday! On your way home from work, on your shopping trip to your friendly supermarket or on your way to see a movie at your favorite theater, make a stop for fuel at a gas station. Make sure to have some gasoline in your tank, because it likely will take you a lot of time to find a gas station that sells E85 or even E15.
Now, I went to Harvard Law School for four days, before I decided that there were too many lawyers around and memorizing case studies was not my forte. But Harvard provides significant value added, apart from being near Harvard Square and Boston. I was exposed to terms and content related to antitrust, restraint of trade, collusion and monopolies. Now, I didn’t stay long enough to know whether those concepts applied to oil companies that restrict consumer choices of alternative fuel. Probably not, because I am sure, by now, one of my Harvard colleagues would have filed a well-reimbursed case to break open the fuel market to options like ethanol, methanol and more. But whether legal or not, oil companies deserve their comeuppance for limiting many of us who, too often, are required to use more expensive, environmentally harmful gasoline, instead of existing, safe, alternative fuels.
How do they do this? Well, if you are a gas station owned or franchised by an oil company, your contract and rules related to behavior often prevent you from adding a pump or adding to an existing pump to sell E15 or E85. As relevant, since oil companies generally require the stations they own to buy fuel from them, and since they don’t sell E15 or E85, adding a pump would be akin to waiting for the hereafter (and acting on faith that you will get there).
Wait, there is more! Every now and then an oil company wants to publicly show it is a bit beneficent (for image purposes), but don’t hold your breath with respect to proof that image and reality are the same. Sure, you might find an alternative-fuel pump near the rear side of the garage proximate to the men’s room, or, if you are lucky, on the side of the station near the air pump. Most oil-company-owned stations and franchisees are generally precluded from putting an alternative-fuel pump under the covered island or space out front. They also face restrictions on advertising alternative fuels as an available product and oil-company pricing limits competition from alternative fuels.
Congress has refused to enact open fuels legislation, which would require oil companies to open up their gas stations to other fuels. Ongoing efforts by public and private sector advocates, as well as nonprofit groups, to encourage policies that would convert older cars to flex-fuel vehicles and to encourage Detroit to build more FFVs could well lead to a large consumer market for alternative fuels and generate a positive market reaction among independent gas companies and, perhaps, even some smart oil companies. While I have been wading through the pros and cons of allowing oil companies to increase exports to other nations, I do believe that if increased exports are in the nation’s future, they should be approved only if the oil companies agree to require their stations and franchises to offer alternative fuels in a primary space alongside gasoline. A bit of tat for tat is in the public interest. Let freedom ring for consumer! Let capitalism mean competition for gasoline and alternative fuels at your nearby gas station! Oh, I forgot, alternative fuel station!
Rin Tin Tin, RINs and the price of ethanol
Is the son or daughter of Rin Tin Tin alive and well? For a while I thought he or she was, while catching up on my reading over the weekend. I kept reading articles about RINs (Renewable Identification Numbers), their possible impact on the ethanol market and relatively high ethanol prices, despite the apparent weakening of the ethanol market. There seemed to be RINs and more RINs on every page I turned! Because I hadn’t slept for two nights, I couldn’t really focus on the contents of the articles, but only on the dog Rin Tin Tin and his offspring. How many of you have done that? Come on, be honest. Don’t make me feel bad!
I felt guilty after it became obvious that my focus on Rin Tin Tin resulted from a tired brain and eyes. I am back to the complex world of RINs today. (I had a bit of sleep).
Okay, you ask, “What the hell are RINs?” They are sort of a pass at reflecting company fulfillment of government mandates concerning biofuels. For this article, think ethanol! They are issued at the point of ethanol production or the purchase of the fuel by companies. They are approved by the EPA. They reflect a credit that verifies that the required amount of ethanol has actually been blended into gasoline. Succinctly, the Renewable Fuel Legislation, now the law of the land, mandates that a Renewable Identification Number (RIN) must be attached to every produced or imported gallon of renewable fuel in the U.S. One more thing, RINs are separated from the batch of renewable fuel when it is blended with gasoline. This fact indicates compliance with the law and Renewable Volume Obligations (RVOs). Credits, at this juncture, can be used for trading purposes.
In 2012, before the EPA’s Nov. 2013 proposal to change RIN quotas and lower requirements for ethanol, the price of RINs was very volatile. Initially, they ranged around 1 to 10 cents a gallon. By spring of 2013, however, they were around $1.
Why the price increase and what does it bode for the price of ethanol in the future? Initially, the RINs were thought of as a way to encourage refiners to produce renewable fuels, like ethanol, and to “pay” for credits if they don’t “play” by meeting fuel targets.
Part of the volatility and increase in costs of RINs, probably, has to do with speculation by banks and other financial institutions. Thomas D. O’Malley, chairman of PBF Energy, indicated in a recent New York Times article that financial institutions “helped transform an environmental program into a profit machine…These things were designed to monitor the inclusion of ethanol in the gasoline pool…They weren’t designed to become a speculative item. For the life of me, I can’t see the justification for it.” Interviews with members of the financial community, conducted by the New York Times, seem to suggest agreement with O’Malley.
According to the Times, speculation in RINs “could have consequences for consumers. In the end, energy analysts say, the outcome will be felt at the gas pumps — as the higher cost of the ethanol credits get tacked onto the price of a gallon of gasoline.” The Times reports that the “credits, which cost 7 cents each in January [2013], peaked at $1.43 in July, and [were] trading for 60 cents” in September. Jordan Godwin in the Barrel Blog indicated that like RINs in 2013, ethanol prices in 2014 are downright wacky. “In a matter of less than two months, ethanol prices went from six-month lows to eight-year highs.” Godwin and others blame delayed returning train cars during the winter and constraints on supply and production. I would add speculation by Wall Street and uncertainty as to the impact and longevity of EPA’s new regulations concerning the reduced mandates for ethanol and other biofuels. It’s a dilemma for proponents of alternative fuels. Less speculation regarding trading, sustained predictable production and refinement of the distribution system, (along with avoidance by some retailers and blenders to price ethanol well over costs) would facilitate more competition with gasoline at the pump. More predictable competition and larger sales at the pump of E15 and E85 would generate more private-sector fixes to the ethanol supply chain as well as likely stabilize prices and, over time, lower them. In light of ethanol’s benefits to the nation, wise folks might be asked to find policies and stimulate market behavior that permit the American people to have it both ways.
Hawks Are Out Again: Mistakenly Casting Doubt on Ethanol
The Hawks are out again. One of my favorite service organizations, the American Automobile Association (AAA), in conjunction with media outlets, has again attacked the use of ethanol in cars. It’s quite sad.
I will still keep my membership card. The AAA is the Walmart, Costco or Nordstrom of the automobile industry when it comes to service at relatively low costs to its members. If you get a flat tire on a sparsely traveled road when it’s raining or snowing, the AAA, following the Postal Service norm, “come rain or snow,” will get there reasonably quickly to help you. Get stuck in your four story garage with a dead battery! Don’t fret or fear, your neighborhood AAA repair truck will be at your side within a relatively short time. It,generally, will “get you to your work on time.” Do I sound like Julie Andrews or the cast in “My Fair Lady?”
While I don’t lose sleep over the question (I only get two hours of sleep even without thinking about the AAA), I often wonder why the AAA appears to join with those, particularly in the oil industry, who seem to want to confuse flex fuel vehicle owners and owners of older cars able to convert their engines easily and cheaply, about the wisdom of using ethanol.
Conversion of older cars and extended use of already approved flex fuel cars as well as increased use of ethanol by both sets of vehicles will result in many benefits, particularly when compared to gasoline. For example, ethanol according to many, many independent studies by qualified researchers is a safer, cheaper, and more environmentally friendly fuel than gasoline. While what is and what is not a fact often becomes a metaphysical question and 100% certainty becomes a question often for philosophers more than scientists, trust me — ethanol is a good but is not a perfect alternative fuel. It is better than gasoline. Right now a perfect fuel does not exist! Remember that the enemy of the present good is often the distant perfect.
Despite AAA’s press releases, EPA studies involving more rigorous methodology, including strategic sampling of a range of cars, indicate that engine damage is almost a nonoccurrence when using E15. E10 has been around for a long time with no discernable engine impact and E85, after extensive testing, has been approved for flex fuel cars.
Understandably, ethanol, given improvements in new car engines and tighter fuel standards, reflects fewer benefits than shown in relatively recent studies concerning ghg emissions, and pollutants like SOx and NOx. But ethanol still provides significantly more environmental benefits and less costs to the consumer now than gasoline.
The differences between ethanol and gasoline will become even more apparent if you assume that Americans use their God-given noggin and opt to convert their older cars to accept alternative fuels. It’s cheap and safe and can be done with a kit, or with quick software or tuning fix for some cars. Similarly, there are nearly 15,000,000 flex fuel cars in the U.S. Most owners do not know they have such a car. Look at the sticker in the back of the car or fuel cap. You probably are the proud owner of a flex fuel vehicle and, once you recognize this fact, you can use ethanol without risk. Using ethanol, both for flex fuel cars and converted older vehicles will likely lower your gasoline costs and will contribute to a healthier environment. Tell your neighbors! Tell your friends! Tell your significant other! Tell your spouse!
Clearly, you will see the environmental benefits to your community, state and nation, if you abandon the conventional way of measuring emissions and pollutant reductions and use tons. The new graphic will portray a visible and important increase in the actual emissions and pollutants eliminated from the atmosphere. It also will emphasize the importance of extending the number of vehicles that can use ethanol through conversion of older cars to flex fuel vehicles and the production of increased numbers of flex fuel vehicles. If the owners of both sets of cars increasingly fuel their vehicles with mostly ethanol (an objective of a number of demonstrations and pilot programs in several states), the President’s desire to wean the nation off of gasoline will come closer to fruition. The scale up will provide a transition approach to open fuel markets until competitive renewable fuels become ready for prime market time.
Altruism Aside, Is Ethanol A Competitive Alternative Fuel?
I was a bit under the weather this past weekend. I thought it would be a good time to catch up on some reading; something assumedly simple- the relatively recent literature concerning the ability of ethanol, particularly E85, to compete with gasoline and the capacity of consumers to make rational decisions in their choice of alternative fuels.
By Sunday night, apart from watching the Denver Broncos happily beat New England on TV, and the amusing dialogue and extensive media time generated by Seattle’s cornerback, Richard Sherman, concerning his athletic and his academic prowess; I spent about 10 hours reviewing several well cited pieces concerning the price relationship between ethanol and gasoline. I also read the intense, often seemingly less than civil debate in papers authored by two professors at Iowa State (Dermot Hayes and Xiadong Du) and two at MIT (Christopher Knittel and Aaron Smith) concerning methodology associated with defining the relationship between ethanol and gasoline prices. (The Iowa and MIT faculty vigorously attacked each other, sometimes personally, over mistaken attribution of research funding sources. More important, the Iowa folks generally argued that their data suggested a link between ethanol production and the price of gasoline. They indicated that, as ethanol production increased the price of gasoline decreased relative to the price of crude oil.
The MIT folks poo poo’d their distant colleagues’ findings. They indicated that their empirically based models illustrate only a statistically insignificant set of relationships concerning ethanol, gasoline and crude oil prices. They also opined that the Iowa writers misapplied the crack ratio –the relationship of gasoline to crude oil prices- and did not use or mistakenly used the crack spread ratio (the weighted average of the gasoline and distillate products produced by a barrel of crude oil minus the cost of crude). Put in another way, what the Iowa writers recorded was correlation not causation. (I know the etymology but we need to help the economists among us find a better set of terms than crack spread and crack ratio. For a minute, I thought that the texts described a line up at a police station or FBI statistics about drug use.)
What can we learn from recent literature about the effect of ethanol production and gasoline prices at the pump?
1. Most independent experts, not affiliated with advocacy groups, seem willing to support as fact that increased ethanol use, at times, will lower the price of gasoline or slow the increase in the price of gasoline. But the caveat is “somewhat.” They disagree on how much on either side of zero. The recent conventional wisdom, stimulated by the Iowa study that ethanol has and likely will reduce the wholesale price by $.89 cents to $1.09 per gallon seems wrong. It appears to reflect an overstatement based on analyses and models that do not accommodate the many complex variables affecting price and costs (e.g. costs of refining, rapid changes in the costs of corn, the costs of distribution, the lack of infrastructure, the unanticipated increases or decreases in costs of crude oil based on investor speculation, escalation or de-escalation of tension in Middle East, uncertain federal policy, etc.). If I were a betting person, I would place my bet on Knittel and Smith’s conclusions that, over time, the price impact of ethanol at the pump on gasoline prices is likely marginal at best.
2. However, to be fair, some scholars and practitioners in the energy business believe that if gasoline is blended with a larger proportion of ethanol (e.g. E85), the price of a gallon of fuel could well drop, given the idiosyncrasies of the present market. If this occurs and the reduction appears to consumers as beneficial, a number of observers think that owners of flex fuel vehicles (new or converted) could be enticed to switch to E85. What they generally don’t know, is the cross over point where alternative fuels like E85 become a viable option to drivers because the prices seem to be a good deal. A smart and astute participant in a recent forum on alternative fuels indicated that “people drive to COSTCO or Wal-Mart to save 5-8 cents a gallon on gasoline. Why wouldn’t they switch to E85 blends, if they reflected similar or indeed larger savings and fuel stations were accessible?”
Maybe they would, maybe they wouldn’t! If the price is low enough, many drivers will likely engage in personal opportunity costing. But what is low enough? Getting gas at Wal-Mart and Costco is different from getting E85. Gas is a familiar product to most drivers. Consumers of E85 will have to surmount doubts over product safety, stimulated, I believe erroneously, by groups such as the AAA. Further, because E85 will get fewer miles per gallon, drivers will probably think about perceived price savings in the context of miles per gallon and extra trips to the fuel station (If they forget to do the personal math, they will be reminded to do so by oil companies).
3. Uncertainty exists concerning how much consumers will pay for ethanol based on personal preferences or commitments to societal well-being, what I call the altruism thing.
As one author put it, “ …the demand for ethanol (E85) as a substitute (E10) is sensitive to relative fuel prices: a $.10 per gallon increase in ethanol’s price relative to gasoline leads to a 12-16% decrease in quantity of ethanol demanded. Price responses are considerably smaller, however, than they would be if households had identical willingness to pay for ethanol as a gasoline substitute and… results imply that some households are willing to pay a premium for ethanol.”
Why? Maybe to improve the environment, provide support for farmers, to express concern over national security, etc. A recent report from Brazil indicates that some Brazilians are willing to pay more for alternative fuels because of what seem to be altruistic reasons. Before we say hallelujah, I should note that we don’t really know the numbers seeking salvation. They are not your average household but rather as one economist notes they are likely “marginal” households in terms of numbers. Further, several respected survey firms in the U.S. doubt that goals related to the larger community or nation, even if consumers articulate them in their living rooms, will overcome large differences between the price of E85 and gasoline, if they occur.
Similarly, altruism or civic values will not overcome fear of engine damage or the need for relatively long trips to fuel stations to secure alternative fuels. The pews, at least until we know more, probably will remain filled with a proportionately large share of guilty drivers on Saturday or Sunday.
The Fuel Freedom Foundation is involved in three state pilot projects aimed at converting existing cars to flex fuel cars; cars that will permit their owners to use natural gas based fuel such as ethanol and, when it is legal, methanol. Hopefully the pilot projects, combined with strategic federal, state, foundation and private sector supported research, will expand knowledge concerning consumer decisions and variables such as the importance of price differentials, altruism, distance, access, etc.
A study supported by Fuel Freedom Foundation recently completed by the respected independent Resources for the Future optimistically noted that “…we see alternative pathways for bring a lower-cost E85 to the pump. If and when ethanol produced by the newly patented, NG-driven Celanese process becomes available, owners of FFVs could realize substantial cost savings, up to $0.83/gge in 2015. If and when cellulosic ethanol becomes available at projected cost for full-scale productions, owners of FFFs could realize similar cost savings.”
Sleep easy! Good Times are coming for the nation and the consumer.
Model building, Playboy and the impact of ethanol on gasoline prices
I recently read a number of provocative articles (or their summaries) by MIT’s Christopher Knittel and Aaron Smith. They faulted a pair of respected researchers from Iowa State University, Dermot Hayes and Ziaodong Du, in somewhat harsh tones. According to Knittel, the Iowa State pair, in their ethanol-related studies over a three year period (from 2009 through 2012), exaggerated the impact of ethanol on gas prices using relatively low present day ethanol blends.
I thought I was reading the script for a new urban crime show about drugs. Knittel, frequently, used terms like crack ratio and crack spread, ostensibly to note the weak link, found by Hayes at Iowa State, between the prices of ethanol and oil and both to gas costs at the pump. According to the authors, the price of gasoline is not substantially affected by the crack ratio; that is, the relative value of gasoline compared to oil or the price of gasoline divided by the price of oil and the current volume of its ethanol content.
Knittel’s papers angered Hayes, of the Iowa study. He claimed that, over time, the crack ratio and crack spread reflected a pretty strong causal relationship to gas prices. Language in his response to Knittel’s critique reminded me of those wonderful days when I was a dean, listening to different faculty, sometimes personally and sometimes based on methodology, criticize other faculty based on differing research results. The search for academic truth is often a noble road, but paraphrasing Robert Frost, a “road less traveled” — a road often full of human frailty and intellectual potholes.
Despite their critique of each other, both Knittel and Hayes’ studies are important and both, when read in context, should help one better understand the role of ethanol in affecting the cost of gas at the pump. Knittel is more right than wrong when he indicates that the crack ratio and spread does not fully explain the effect of ethanol on gas and oil prices, over time, and he is also correct in challenging the model used by Hayes to identify a reduction of $0.89 to $1.09 on gas prices because of higher ethanol production and higher crude oil prices.
Hypothetically, in isolation from other variables, the higher the crack ratio, the higher the price of gasoline. Further, if the price of ethanol is relatively low or on a downward trend, increased use of ethanol in gasoline blends, in theory, would cause the crack ratio to go down and the spreads to be higher, assuming gas prices remain the same or increase. Good news for consumers! Right? Maybe? Not always? Not at all? Not sure? What if?
I cannot claim real modeling expertise and would not, even for a minute, arbitrate between Knittel and Hayes concerning their use of models and its result — in terms of Hayes, significant impact of ethanol, in terms of Knittel, minor impact of ethanol.
But in terms of the policy argument between them, I suspect Knittel comes out the winner (full disclosure: I did graduate from MIT and while I love Iowa’s rolling hills, I do not like the climate and the fact that the state does not have a great symphony, nor a NFL football or American League baseball team). He points out that the crack ratio’s fluctuations in the ‘80s occurred when oil prices both declined and increased. Ethanol was not a factor and the movements in the crack ratio were not based on ethanol production. He seemingly, correctly, faults the folks in Iowa for not using the crack spread model in their 2011 and 2012 papers to evaluate the impact of eliminating ethanol because the two models —crack ratio which they used and crack spread which they didn’t — produce significantly different results and policy implications.
What does the dispute over models and model use have to do with public policy? A lot! The ethanol supporters touted the Iowa studies to support their claim that increased ethanol use reduces costs to consumers in a major way. Conversely, the ethanol critics suggest that the Knittel analysis debunks the assertion that use of ethanol as a blend will reduce gas prices in a major way.
Knittel suggests the Iowa studies vastly overstate the cost-related benefits of ethanol to the consumer and that Iowa’s model disregards or blurs the effect of price changes and swings in price of both ethanol and oil. Knittel also indicates that that the relationships between oil and gas prices, as well as oil, gas and ethanol prices are much less precise and more complicated than indicated by Hayes’ modeling efforts. Prices of all three fuels are much more subject to behavior and external events than acknowledged by either Knittel or Hayes.
The dialogue between Knittel and Hayes is helpful in sorting cost and price issues regarding ethanol and gasoline. I hope they continue at it, with less emotion, and with analyses better grounded in methodological analyses that generate a better job of linking model building with experience and empiricism. Meanwhile, no matter whether you believe the effect of ethanol on gas prices is high, moderate or low, if the U.S. government acquiesces in the use of higher ethanol blends like E60 and E85, and if the cost spread between ethanol and gasoline continues, an increasingly visible positive impact on fuel prices will likely be witnessed at the pump. Apart from any possible price differential related to use of higher blends, increased use of ethanol as an alternative transitional transportation fuel is in the public interest. According to most reputable studies, such use will respond well to many environmental problems caused by gasoline and it will help reduce America’s need to import oil…a continuing security problem.
Epilogue: I once taught a reasonably popular class on policy development and models. To liven up the class, I told the students that economic and policy models are abstractions of reality and to the extent that the models’ abstractions helps students understand reality, they are “good” models. They asked for examples. It was a late evening and I was tired. I told them to go look at the centerpieces in Playboy and Playgirl. Both presented models of airbrushed men and woman. At our next class, I asked the students if the models increased their understanding of men and women. They were bright and eager students, at least for this assignment, and they indicated, “No.” The models tilted too far toward abstractions and too far away from real world experience. They seemed to learn a lesson about the value of at least some models.
