Once-Darling Ethanol Losing Friends In High Places
theodp writes "It's now conceivable, says BusinessWeek's Ed Wallace, that the myth of ethanol as the salvation for America's energy problem is coming to an end. Curiously, the alternative fuel may be done in by an unlikely collection of foes. Fervidly pro-ethanol in the last decade of his political career, former VP Al Gore reversed course in late November and apologized for supporting ethanol, which apparently was more about ingratiating himself to farmers. A week later, Energy Secretary Steven Chu piled on, saying: 'The future of transportation fuels shouldn't involve ethanol.' And in December, a group of small-engine manufacturers, automakers, and boat manufacturers filed suit in the US Court of Appeals to vacate the EPA's October ruling that using a 15% blend of ethanol in fuel supplies would not harm 2007 and newer vehicles. Despite all of this, the newly-elected Congress has extended the 45 cent-per-gallon ethanol blending tax credit that was due to expire, a move that is expected to reduce revenue by $6.25 billion in 2011. 'The ethanol insanity,' longtime-critic Wallace laments, 'will continue until so many cars and motors are damaged by this fuel additive that the public outcry can no longer be ignored.'"
The "newly-elected" Congress hasn't been seated yet.
Dissolve... Resolve... Evolve...
Here's a great article about what is happening today with ethanol:

"He explains that the legal limit is 10% but that all the fuel distributors cheat and mix in some extra alcohol so they can make a buck. When the mix gets to 15% it’s toxic for two cycle engines. And that is what killed my machines."
Kiss your chainsaw or gas boat motor goodbye. And your car engine, if the EPA gets their way of increasing the "limit" to 15%.
Have you ever actually tried to eat the grade of corn used for corn ethanol? I thought not, but believe me, don't try it, you won't be able to, it's a grade lower than that used for silage/cattle feed. It's grown on land too marginal for real human crops and tastes.
Ah, No. Not true.
Ethanol has taken over prime farm corn land.
Ethanol has actually driven up the price of silage corn, and beef.
It is most often the exact same corn as silage, because there is no point in switching to a lower grade. The seed, planting, and harvesting costs the same, and you cut your market options by growing anything other than cattle grade corn.
We don't directly eat silage either, so just because it does not taste good to humans when eaten directly is a hollow argument. It tastes pretty good when you eat the cow/pig.
I'm sure this is where the vegans jump in and pontificate about eating animals, but thats not what this thread is about.
Sig Battery depleted. Reverting to safe mode.
The senators representing America's corn-belt states are actually a pretty even split between republicans and democrats, hence "R/D". Is that illogical? While their positions on god, guns, and gays may differ along party lines, their positions on corn ethanol tend to be homogeneous across them(the cynic might remark that, on that issue, those senators can basically be treated as "Senator Cornfed, ConAgra/ADM"...)
I hope your little ignorant ass is replaced by an agricultural robot.
With the 10% Ethanol mix, his 12.25 gallon fill-up contained 11.0 gallons of gasoline. He was able to travel 265 miles. That gives us 265/11 = 24.1 mpg, where gallons refers to only the gasoline portion. Yes, I'm ignoring the ethanol portion of the fill-up on purpose.
With pure gasoline, he went 300 miles on a 12.25 gallon fill-up, giving 300/12.25 = 24.5 mpg.
Do you see what happened? At best, the ethanol does absolutely nothing useful! At worst, it actually makes your car use even more gasoline. You don't even need the other arguments about it costing more and eating away at engine components to realize that it's a complete waste.
I'm a leaf on the wind. Watch how I soar.
First the jury has been in for a long time that in terms of Energy per dollar Corn or sugar based ethanol are never going to be a good idea in the US for feedstocks that come from the food chain. However cellolosic ethanol (switch grass, poplar tree, cellulosic waste, etc...) may be quite a good idea. There are strong arguments for them that have yet to be defeated. They need less irrigation and can be grown on lands or seasons otherwise unsuited for crops.
The big bug-a-boo with these is that they are waiting for a scientific breaktrhough for a process to change cellulose into simple sugars or directly to ethanol or gasoline. There's lots of ways to approach this but all of them are not at the efficiency needed yet. It's not an easy proposal: if digesting cellulose was super easy then more bugs would do it already. It's actually not the cellulose that's the biggest problem, it's the lignose which is about 30%+ of the plant thats slightly harder to deal with biochemically.
It's likely that some breakthroughs will occur. Theres lots of irons in the fire. Some of them may scale. But if you had to do it tommorrow chances are you'd bet on the wrong pony if you went with one particular approach.
Thus the primary role that starch and sugar based ethanol plays now is that it seeds the pipeline with ethanol now, so the infrastructure will be in place when cellulosic ethanol comes on line.
Now why ethanol and not something else more energy efficient. Butanol for example. Or other liquid fuels. THe problem is that when you ad up the cost of replacing our fleet of existing internal combustion engines and fuel infrastructure it's a huge huge huge sum. You can't just pick the "optimal" fuel purely from an maximal energy standpoint. You have to have a way there that does not start with a non-starter like chucking out all the existing engines. Hence Ethanol looks like the common denominator. It's not bad. It's easier to produce ethanol from grains now than it is butanol or gasoline. and it works in the cars we have up to a point.
As long as we are comminting to cellulosic ethanol, some use of food crops to produce grain-based ethanol now is justifiable. It just can't continue in the long run.
Another route is commit to bio-diesel from algae. This too has some issues to solve to make it scalable. It can use lower quality water. it can use low grade lands. it is easier to "dry" than ethanol because it is not water soluble so there's less energy waste in turning it into fuels. And you might be able to think of some byproduct for the waste stream from algae (maybe animal feed or fertilizer). SOme of the challenges here are very simple sounding, though no one has entirely solved them yet: how do we quadruple the lipid yield, and how to we get enough CO2 into the water (without burning fuel to create it and pump it.).
There is enough bad land to fuel the entire nation if we can solve those scaling products.
It has a path forward through the trucking system (diesel) and through aviation fuels and military fuels. The latter can pay premium prices to subsidize the product effectively since those fuels are more expensive than consume fuels.
Eventually however that path requires replacing the automobile fleet. But given the path forward in the near term this may not be a non-starter.
Some drink at the fountain of knowledge. Others just gargle.
Then you don't understand it. All my generators have been four stroke, as is the boat. Living in a small town, gas without ethanol is not available locally, and in North Carolina, they were mandating ethanol years before the feds due to pollution. Running Stabil in fuel is nice and is done year round but doesn't change the chemical reality that ethanol is hygroscopic. Most engines have steel parts. Water rusts steel. Engines that aren't run regularly and have tanks that vent to the atmosphere build up water. Not quite sure why you don't get it. It would appear the majority here do.
Tequila: It's not just for breakfast anymore!
I work in the marine engine trade. (western U.S.) Ethanol has been a boon to the gasoline engine repair and maritime rescue business. It is estimated by marine trade originations that gasoline and ethanol mixed fuels currently cause about 70-85% of engine failures. Not really a type of additional work we want.These engines (and outboards) and fuel tanks were never designed for this fuel. Unlike modern autos, marine fuel tanks are vented and absorb moisture rich air. Water related corrosion adds to the alcohol damage. I do not think anyone has worked out just the cost in lives lost at sea, lost boats, and the damage to the marine trades has resulted from this fuel. We only get to work on the boats that made it back.
