Is E85 Dead Now? 556
twdorris writes "With a stoichiometric ratio far lower than that of gasoline (much lower than the price difference), buying the E85 ethanol fuel blend instead of gasoline was already hard to justify. Unless you raced your car on a track where E85 provided a great alternative to race fuel, it really didn't make financial sense. And there are other reasons not to buy E85, too. Like the impact corn-based ethanol is having on food prices or the questionable emissions results (PDF). So, now that the ethanol subsidies provided by the U.S. federal government are scheduled to end this summer, it's going to be even harder to justify E85 (at least in the U.S.). This change will basically make a gallon of E85 cost the same or slightly more than gasoline. With so many things working against it, are the days numbered for readily available E85 at your local gas station? And should it have ever even been made available to begin with? How much did all that government-backed R&D and tax credits cost us for something that was pretty clearly questionable to begin with?"

I know in my own car (Nissan Altima, and I LOVE it), I seem to get a bit more mileage when I'm burning pure gasoline -- about 5% more.

I believe that in most cases, it's more than just semantics. Most (not all) corn is grown using conventional (petroleum-based) fertilizer. According to Michael Pollan [wikipedia.org], producing one calorie of corn uses two calories of petro-fertilizer. This is only counting fertilizer use, not the additional energy used for farm equipment, moving product/raw materials, the distillation process or loss of energy during distillation.
I'm shocked that this is not cited elsewhere when discussing Ethanol as an energy source, especially when used to reduce our dependency on petroleum (foreign or otherwise). Given that we're using more petroleum to make it than it would save, it appears to be a bit of a boondoggle.

Problem with corn-based ethanol is, once you factor in all the chemical fertilizers and the energy required to grow the corn, harvest it, and refine it into ethanol, you've consumed about as much fossil fuel as you're saving by burning the ethanol. So in reality t's just a convoluted way of burning the same oil you would've burned if you'd used normal gasoline to begin with.
If we could produce it from sugarcane instead (the way Brazil does), the story would be different.

This causes stress in the engine especially when the detonation happens too early while the piston is on the upstroke as well as excessive heat buildup.

The higher the octane rating, the less likely it is to spontaneously combust under high pressures. This is why your higher compression engines don't allow the lower octane ratings.

Octane rating is not a measure of octane content. It's a comparison of the autoignition (e.g. knock) resistance of a given fuel blend to a scale defined by the properties of pure iso-octane (100) and heptane (0). A gasoline with an octane rating of 97 has the same autoignition properties as a mix of 97% octane and 3% heptane. Ethanol's octane rating is at or over 100, and E85 typically has a R+M/2 octane rating of around 95, which is a little higher than retail premium gasolines, and much higher than standard 87-octane gasoline.
The high knock resistance of E85 actually enables engine designs that have higher compression ratios, more boost, etc. to improve efficiency (and power output) which can actually make up some of the reduced range in a vehicle if the engine is designed primarily with E85 in mind rather than standard gasoline. Still, with the fuel only having about 2/3 the energy content of gasoline per unit volume, it's a big gap to close.
Ethanol isn't primarily added because of its octane-boosting properties, however (though those are taken advantage of in formulating the base stock to blend with). It's added because the EPA mandates oxygenated fuels to reduce emissions of CO and other pollutants. Fuels can be oxygenated through the addition of either ethers or alcohols, MTBE being an example of the former, and ethanol an example of the latter. Most states have mandated that oxygenates be specifically made up of ethanol, due to the harmful health effects of MTBE, methanol, and other potential chemicals if they leach into ground water, as well as support from the powerful corn-farming lobby.

We expected about an 18 year return on the cash investment (on paper the value of the land we made an instant profit of about $300 an acre. Dry land it was worth about $1200 an acre, cost about $850 an acre to level and could be sold as irrigated/leveled land at about $2300 at the time. These days you can easily get $3500 an acre and maybe $4k if you are willing to wait for the right buyer). What we didn't foresee was $10 a bushel soybeans starting to be the "average". The increase in production we've seen from being able to water and switch to rise basically went from $20k a year to $60k a year. Now that's been closer to $80 and even close to $100k a couple years and we recouped the cash investment about 2009.
About 2007, the farmers decided basically go to a three crop rotation of 50% rice, 25% soybean, and 25% corn. That lasted about one season because we put a stop to it. There are a couple 20 acre fields that are still "dry land" and those do get corn placed on them every other year and that's fine, but we saw the bubble that was corn. We decided a few years ago to come up with a rotation and stick to it. Don't try and play roulette with the market. That rotation is rice, then the following year double crop spring wheat and come back with late beans. If for some reason that combination stops yielding the returns we desire, then we'll reevaluate. But there is no sense in getting suckered in with hype (like our farmers were). "Oh Corn is high this year, we better plant more next year". Problem is too many other farmers think that way and guess what: next year there is more supply and the price goes down.

Once they've spent all these billions on these ethanol plants the Saudis will drop the price of oil and quickly put them out of business just like they did in the 1980's". Well I'm not sure if it was the Saudis pumping more oil, but the same thing happened. The price of oil dropped like a rock and just long enough to put most of these producers out of business.
We talk about the farms quite a bit and something we did about 2006 was sit down and look at the statistics on prices. Figured out where our high and lows should be. If the price got basically 1 standard deviation above the "average" price over the past 10 years we sold half the stock. If it went up more we sold the rest. If it went back down we'd sell again once it closed just below the price mark (which was $7.03 a bushel).

So ethanol will actually become cheaper!

And this is a reason that I've become a bit more wary about these sorts of government subsidies that are intended to 'kick-start' a particular technology. It's not that I think that it's not a good and valid use of government money to provide this sort of startup from which innovation can flourish but rather the high risk that, having gotten on the gravy train and now being dependent on the government for financing, those industries can often manage to get entrenched into a position from which they cannot be dislodged even after the justification for the subsidy is gone. Look at the sugar industry in the US for instance -- you just can't get rid of the subsidies because they've used all that lucre to buy enough support and now we are absolutely stuck with them.

Corn ethanol is an extremely inefficient way to "store" solar energy.
This whole boondoggle started because the U.S. always runs a corn surplus. The U.S. doesn't want a repeat of the 1930s, where crop failures led to hunger and near starvation, so the government deliberately subsidizes food production (mostly corn) to insure there's an oversupply. The question then becomes, what to do with all this extra corn? A lot of it is sent overseas as foreign aid. A bunch of it is converted to high fructose corn syrup, as a substitute for cane sugar. More still becomes grain feed for livestock, to satisfy our appetite for beef, milk, and cheese. And a few decades ago someone got the bright idea of converting it into ethanol to help ease the country's dependence on foreign oil.
That's the reason the country started making corn ethanol instead of using a more energy-efficient crop like sugar beets. Unfortunately, somewhere along the line, it took on a life of its own, and under the influence of heavy lobbying we started growing corn for the sake of converting it into ethanol, rather than converting only excess corn into ethanol.
Ethanol, provided you make it from a sugar-rich crop, is actually a pretty good way to gather and store solar energy for transportation applications. The alternative (PV solar to electricity to batteries to electric vehicle) is horribly expensive. Wholesale cost of PV solar electricity is about $0.20-$0.25 per kWh, vs. about $0.055 (wholesale) for coal. The Leaf is rated at 34 kWh per 100 miles, or $6.80-$8.50 per 100 miles at wholesale PV solar electricity prices. To travel 100 miles requires 411 kg of batteries (EPA rage of 73 miles on 300 kg).
Brazil estimates its sugar cane ethanol costs $0.83/gal to produce [wilsoncenter.org]. If you figure a Leaf-like car would get 35 mpg, modify that for ethanol's 70% energy density vs. gasoline, that would mean 4.08 gal per 100 miles, or a cost of $3.36 per 100 miles at wholesale cane sugar ethanol prices. The 4.08 gallons needed to move the vehicle 100 miles would only weigh 12.1 kg. So sugar cane ethanol is 2x - 2.5x cheaper and 34x lighter than PV solar (this ignores the engine weight, but I'm just following the criteria of this argument - "storing" solar energy).

Some go so far as to claim that hemp bio-diesel is carbon negative. I'm skeptical about that, but it would be interesting to test the theory.
Unlike ethanol corn, hemp produces a great deal of fiber suitable for textiles and paper as a side-product, even if the main purpose of the crop is bio-diesel.

Even Scientists from Ag departments of California universities have known that looking to corn-based fuels is a bad idea. Look at this report from Professor Tadeusz Patzek, A Professor of Chemical Engineering at the University of California at Berkeley [phoenixpro...ndation.us]:
Excerpts:
Why Corn Ethanol is Unsustainable, Let Us Count the Ways:
4.
Approximately 99% of U.S. corn is fertilized, requiring more fertilizer than any other crop.
Nitrogen fertilizers, herbicides and pesticides are all made from fossil fuels, as is the diesel
fuel, gasoline, LPG, natural gas, electricity, transportation and irrigation used to grow and
transport the corn.
7.
Because ethanol is a toxic and hazardous substance, its use is regulated by OSHA, DOT,
NFPA and NIOSH. Ethanol must be handled with extreme caution because it can enter the
blood stream from breathing the fumes, or by penetration through the skin or mouth. Exposure
can irritate the eyes, nose, mouth, and throat. As such, protective clothing, including gloves
and splash-proof chemical goggles and face shields should be worn by anyone coming in
contact with ethanol.
8.
People are advised not to eat, smoke or drink where ethanol is handled, processed, or stored
since the chemical can easily be absorbed. Moderate exposure can cause headaches, eye
and skin irritation, nausea, and drowsiness, whereas higher levels of exposure (over 1000 parts
per million over an 8-hour period) can cause shortness of breath, genetic mutations, damage to
the liver and central nervous system and unconsciousness. Exposure to ethanol levels of over
3300 ppm can result in death.
9.
Ethanol land requirements: Approximately 50 gallons of ethanol are produced per acre of
corn. Thus 2.8 billion acres of land would be required to generate 140 billion gallons of fuel
used in the USA annually, which is more than 5 times all of the cropland that is actually and
potentially available for all crops in the USA.
10. ...8,360 gallons of water are needed per equivalent gallon of
Ethanol water requirements:
gasoline in the form of ethanol. 140 billion gallons of gasoline are consumed in the USA
annually, times 8,360 gallons of water = 1.17 trillion gallons of water needed to grow and
process enough ethanol for the U.S. economy.

Even in a turbocharged car, during cruise you can already lean and advance the engine like crazy with regular gasoline as there is very little load on it.
