Another huge boondoggle. EISA calls for 250 million gallons of cellulosic ethanol in 21011. We will struggle to make 4-5 million. Now the dreamers want to build plants for a process we don't have. Large amounts of diesel are also needed to gather up all this biomass. It takes a whole lot of it to make a little bit of transportation fuel. I think it's Pete Seeger's great song that ends "When will we ever learn?"
Hold on to your wallets.

With or without subsidies, Corn doesn't cut it. Consider the output per year. 150 bushels yielding 450 gallons. Let's be generous and say 500 gallons. Let's be more generous and say that an average car in the US gets 25 miles per gallon. Yield = 12,500 miles per acre per year, even in Iowa. If they can make it for $3 per gallon, that's fuel for one car costing 12 cents per mile.

Now consider an acre of PV cells in Nevada. Even at the massive price of 25 cents per kWh your cost per mile will be 6 cents. Best of all, assuming 150 kW per acre and 2,000 hours of sunlight per year (when 3,000 may be possible in some places), the yield is 300,000 kWh x 4 miles per kWh = 1.2 million miles per acre per year. That means 100 cars operating at 6 cents per mile vs 1 car operating at 12 cents. Which is better?

Ethanol, corn based, what a waste!

In 2010 ethanol supplied about 10% of the fuel supply for light vehicles. How many Priuses would it take to reduce the demand for gasoline/petroleum for light vehicle fleet by 10%? Well at about 36% reduction of gas consumption per Prius, dividing 10% by 36% gets you 27.7%. That's the percent of the fleet of light vehicles you would need to be Priusus to achieve a 10% reduction in total fuel consumption. 27.7% of the fleet of roughly 260,000,000 cars and light trucks would be 72 MILLION Priuses - to achieve that 10% reduction in fuel consumption, that ethanol is achieving right now.

I wonder how many years it would take to get 72,000,000 Priuses sold? Now the annualized cost of those Priuses would be 72,000,000 x $4,000 (marginal cost for Prius) = $289,000,000,000.
NOw, divide that by 14 (assume 14 yrs useful life) and dividing the $289 Billion by 14 yrs - that gets you an annualized cost for the Priuses of approximately $21,000,000,000.

Hm-m-m-m, compared to $6 billion - as long as the excise tax credit is in effect - that means the Priuses would cost about 3.4 times as much as ethanol (WITH the excise tax credit in place). The Ethanol Federal Excise Tax Credit was due to expire at the end of this year. Without Tea-party and Big Oil lobbying it would have been phased out as the ethanol industry kept improving their efficiency and as oil/gas prices continued to rise - perhaps lasting two to three more years. As it is now, the Excise tax credit will die at the end of this year, meaning you would compare the $21 Billion annualized cost for the Priuses to uh-h-h-h-h, ZERO dollars for ethanol. What a boondoggle!

By the way, because of the increased economic activity from the domestic production of ethanol, tax revenues for all levels of government increase. The increased revenues for the Federal Government are about one third MORE THAN the revenue lost due to the Excise Tax Credit. Man, what a boondoggle!!

Is 'Anonymous' using solar charged PHEV's for his comparison? Let's first not forget that it will be decades before we get to ALL electrical power in the U.S. coming from green power sources.

Of the two PHEVs being sold now, the one that reasonably can be considered an all purpose vehicle, the Volt (the Leaf, realistically, will only be considered as a second vehicle for many years until the range can be increased significantly), costs about $20,000 extra vs a car of comparable payload. It will take decades before PHEVs will be on the road in large enough numbers to result in appreciable reductions in gasoline consumption. It will likely take twenty years for there to be enough PHEVs, along with standard Hybrids, on the road to achieve the 10% fuel consumption reduction we get right now from ethanol.

Please, don't kid yourself that PHEVs will yield, on average, 100% reduction in fuel consumption. To sell significant enough quantitiies of PHEVs to get appreciable reductions if fuel consumption you will have to start selling them to NOT just the city drivers but to more typical - average use drivers which includes longer highway driving. This will for some years mean partial use of the gasoline engine.

THE SIMPLE, UNALTERABLE FACT IS -- YOU CAN REPLACE THE FUEL CARS BURN FASTER THAN YOU CAN REPLACE THE CARS THAT BURN THE FUEL.

Rolf, Bill and anonymous:


I agree ! Bioethanol is a waste in the light of the our Nation's hungry children.


In addition, bioethanol when burned in the engine still generates "greenhouse gas", i.e. carbon dioxide. So, get
stop making bioethanol ! Carbon dioxide has a 10 year "half-life" in the atmosphere which means after generation, it will be around for 70 years in the atmosphere. The pH of the ocean is already changing due to dissolved carbon dioxide !

With all due respect, I think Ms. Bayar is missing the significance of what is happening here. This is NOT a move from corn ethanol to cellulosic, it is a move AWAY from ethanol: "several drop-in biofuel plants and refineries" and "chemical copies of their fossil fuel counterparts". Those descriptions exclude ethanol. Not a moment too soon, I might add.

Ethanol is as terrible fuel: it absorbs moisture out of air, which not only causes corrossion, but could lead to separation. It is also a terrible ingredient for gasoline, increasing the vapor pressure, which leads to more emissions and evaporative loss. To top it off, the transportation of ethanol by truck (since it can't go in existing pipelines) can result in some rather spectaculor fires.

Producing ethanol by fermantation is a joke (slow, low yields and a dilute product requiring much fuel for distillation). Doing so using food as a feedstock is, as the UN rightly stated, a crime against humanity.

Unfortunately, it does not look as if Uncle Sam has learned that he cannot use his vast knowledge (hahaha) to pick technology winners.

Ethanol doesn't supply 10% of light vehicle fuel. And it burns about as much as it supplies to make the stuff in the first place. It is a big taxpayer funded scam.

OK. But what if we burn the ethanol in powerplants, and use the electricity to charge EVs? That gets us down to 4 cents/mile. Other biomass crops could be even cheaper.

Talk about bitter clingers! The concept that biofuels = starvation is a myth, and an old one, at that!

"Let's burn the corn in powerplants!" Brilliant solution.

Does anyone do homework, or do you just let others string together disparate facts and lead you by the nose to a conclusion? "Cars emit CO2, and the West has more cars than China, so China is not causing global warming." Brilliant!

Absolote falsehood, but everyone buys it. Want to cut carbon emissions? Don't focus on auto fuel, focus on Oceanic Shipping fuel, electric power plants, and the factories that make the cars and batteries.

Any idea what the lifetime environmental load of a PHEV is?

Anyone looked at studies involving the retrofit of existing automobiles with high-compression, direct injected, cylinder deactivating motors, coupled with larger tires? [larger tire=more distance travelled per revolution] You need to replace tires regularly anyway....

Never heard of it? You know why? Because no automaker, oil company, or coal company has paid for the dissemination of the information.

Want to talk boondoggle? Did you read the article? To whom did most ethanol subsidies go? Oil companies. Valero already said they'll probably use ethanol without subsidies.

What ends with subsidies is the con games disguised as business. If only we could end the oil subsidies....

1)I agree cellulosic ethanol is not the solution.They in turn creates other problems, how ever much the defenders of cellulosic ethanol defends it. The solution lies in canopied plants producing first generation ethanol - ie based on starch.These plants solve almost all problems
2)Use of large amounts of diesel, furnace oil ( Bunker C) to distill ethanol is ancient and crude technology.There are more sophisticated technologies available which cuts across the use of fossil fuels in ethanol distillation, (i) reducing their requirement to less than 50% of the present usage and (ii) make the investment in refineries much cheaper and (iii)the existing refineries can up grade their output at much lower cost.Whether the subsidies persist or not the refiner can up his profit margin by figures beyond his expectation.The lead time to implement the modifications is less than 3 weeks.

One option to avoid corn from biofuel production to some extent is to encourage plants like Agave(Americana) Sisal Agave which is being used in biofuel production on a massive scale in Mexico. This is a care-free growth plant and has other uses as well.

I do not agree with you.What you say is true when considering dehydrated ethanol (Near 99% pure), not hydrated ethanol(near 95% pure)Hydrated ethanol is the product off a rectified spirits distillery, it does not absorb moisture out of the air. I know of distilleries that use PVC based pipe lines to transfer hydrous ethanol( now do not start picking on whether use of PVC is hygienic).Ethanol over 60% catches fire - That is how the British Proof was described in the olden days. Gasoline is no exception to this rule it too catches fire. That is why you are told not to have a lighted cigarette or light a match stick or a cigarette lighter at the gasoline station.

Hydrous ethanol is used in Brazil and was used during WWII.Number of research papers had been published in the US itself on the use of hydrous ethanol as a fuel and the way to overcome the deficiencies, especially in the start up and acceleration.Then there is the question of usage, with gasoline having nearly 25% more energy. This shortcoming can be easily overcome.After all gasoline itself is not a virgin product.

The use of dehydrated ethanol as a fuel had been created by one or more groups with vested interests.

I agree that food based feed stock should not be used to produce fuel. The use of food based feed stock is something that arose due to the past experience, experience dating back to Pliny the Elder, who died during the eruption in Pompeii.

Corn sugar cane wheat rice switch grass, miscanthus giant grass etc etc are not the solution to the source of feed stock for fuel ethanol. They create more problems than the problem they attempt to solve.Canopied plants with high yields of starch is the solution. There are many such plants Fortunately They thrive in the tropics where labour is very cheap, making the end product comparatively cheaper.Is not the South US in the tropics.These plants can be grown there.Even if they are grown and distilled in Africa one should not grumble after all crude is transported across half the world in addition countries maintain navies to protect the supply routes.

Solutions had been found for slow fermentation with low yields.Slow fermentation and low yields are a matter of history.These technologies are well known.

The high usage of fuel for distillation itself can be overcome.The existing distillation technology is old and archaic.The problem is that usage of technology cannot be negatively selective.

Anumakonda (Dr.A.Jagadeesh Nellore(AP),India. Again I disagree.Neither Agave nor the members of the graminea family is the solution. They cause environmental problems and aggravate what is there.
Please see above- canopied plants with starch is the solution. The canopies protect the soil, absorb CO2 and help to retain water.The technology of starch fermentation was known from the time of Pliny the elder.
One has to innovate ways and means of harvesting and keeping the canopies low, closer to the ground.

On the question of agave, the claims look impressive:

www.slideshare.net/agaveproject/Agave-Project-Presentation

But Dr. Anumakonda Jagadeesh writes that "Agave ... is being used in biofuel production on a massive scale in Mexico." Is it really? According to the director of The Agave Project, Arturo Velez, writing on the link above:

"We still don't have all the necessary infrastructure to commercially produce ethanol in Mexico, although some tequila industries are somewhat interested. If they decided to give it a try, we could be commercially producing ethanol in 6 to 8 months. Another option is to export agave-derived feedstocks for ethanol production to the USA. That can be done immediately."

If, could, perhaps. Doesn't sound like "on a massive scale" yet to me.

I know more about squeezing more power from small engines than I do about ethanol production.

Water in your fuel is not the problem, gasoline is. High performance engines have often used water injection to limit detonation. Since at least WW2, alcohol and water injection were used to increase the power of aircraft.

What do you put in your gas tank when water condenses into it? Alcohol.

Alcohols, even hydrated, allow higher compression, which in turn increases expansion, which is the force that drives the pistons.

Although BTU content is often cited as a reason for the inferiority of alcohol fuels, this is largely a fallacy in IC engines, where heat is anathema to efficiency. Heat causes detonation, which is why 2/3 of the BTU content is eliminated through the cooling system and tailpipe.

Gasoline is a 19th-century grocery store stain remover doped up to try to match ethanol and methanol engine performance.

Either diesel, electric, ethanol, methanol, or natural gas engines are better than gasoline engines.

Flex fuel vehicles run poorly on E85 because they run poorly on gasoline. A cheap low-compression engine does not improve because you use premium fuel. High performance engines need premium fuel, extreme performance engines need alcohol.

Return to the subject, the article about subsidies. It would only seem an honest approach to eliminate subsidies from both alcohol and petroleum production.

Without tax breaks, incentives, strategic petroleum favoritism, and military defense of petroleum interests, gasoline refiners would likely turn to alcohol production. Gasoline, after all is not a rigidly defined compound but a generic name based on a defunct brand. Whatever they make it out of, they can still call it gasoline.

If Uncle Sam wasn't living on oil company graft, hadn't already 'picked' oil as the winner, we would have turned to other fuels before most of us were old enough to drive.

rolf-westgard-67277 : No body can convince you otherwise.When eventually the fossil fuels dry up or become expensive what is the alternative left, hybrids,flexi fuels all of which require fossil fuels, solar panels. None of them are going to be affordable to the average motorist in the next 75 - 100 years.

Levitation is out, if the technology was known as reported, it is lost by now.

What are the left over alternatives, bicycles, horse carts and bullock carts.

to rolf-westgard-67277;

Indeed yes, ethanol did provide about 10% of the fuel for light vehicle transportation in 2010. Here are the facts with links.

Production of ethanol, 2010: 13,321,000,000 gallons

this is from the U.S. Energy Information Administration (US-EIA). see:
http://www.afdc.energy.gov/afdc/data/docs/ethanol_production_consumption.xls

Total 'finished motor gasoline' delivered in U.S. 2010 = 3,282,319,000 bbls x 42 = 137,857,398,000 gallons.

From the U.S. Energy Information Administration (US-EIA):
http://205.254.135.24/dnav/pet/pet_cons_psup_dc_nus_mbbl_a.htm

U.S. Petroleum Products supplied, finished motor gasoline (NOTE: 'Finished motor gasoline includes all ethanol blended gasoline (e.g. E10, E85).'

see Definitions (U.S. Energy Information Administration (US-EIA): http://205.254.135.24/dnav/pet/TblDefs/pet_cons_psup_tbldef2.asp

Total Ethanol Supplied / Total Gasoline (incl. ethanol) supplied = Ethanol % of total fuel for light vehicle transportation.

Thus: 13,321,000,000/137,857,398,000 = 9.7%

for 2011 ethanol will be at least 10% of total fuel supplied for light transportation vehicles.

REDARDING THE EFFIECIENCY OF ETHANOL PRODUCTION - the U.S. Dept. of Energy (the Argonne National Laboratory, Michael Wang), U. S. Dept of Agriculture (Hosien Shapouri), Michigan State University - Bruce Dale, PhD, among others have established that ethanol production yields about 1.6 to 2.3 times as much energy in the fuel as was consumed in fossil fuels to produce the ethanol.

Sorry, but I can only use actual proven facts in this discussion. Flights of fancy and urban legends I will leave to you.

The US Dept. of Agriculture industry survey published in 2010 (using industry data from 2008) showed an energy gain of 1.9 to 2.3 to 1. That is, ethanol producers were turning out ethanol with 1.9 to 2.3 units of energy for every 1 unit of fossil fuel energy consumed to make the ethanol (this includes the energy used in raising and harvesting the corn feedstock).

The quantity of ethanol in gasoline should be deducted before calculating the percentage.

137 - 13 = 124 billion gallons of gasoline

13 / 124 = 10.48% ethanol

Naysayers have always said that ethanol would never be more than 5% of the gasoline supply.

@ Bill and John,

Your figures relate to volume. Most discussions of energy normalize volumes for differences in energy density. In that case, the contribution of ethanol to total supply of gasoline-like fuels was more like 7%.
Comment

September 20, 2011
Energy density is not as relevant as fuel economy. According to this study:

http://www.ethanol.org/pdf/contentmgmt/ACEFuelEconomyStudy_001.pdf

10% ethanol resulted in a 1.5% reduction in fuel economy. That would put ethanol at 8.98%, as the amount of energy supplied for gasoline powered vehicles.

Bill,You have not specified the feed stock on which these calculations are based.Since you refer to Shapouri, Wang I believe that you are referring to Corn based ethanol. ( I must read Bruce Dale tonight. The figure for Corn is under attack by Pimentel and Patzeck.

I look at it on a different manner.Corn & Sugar Cane need capital work yearly. Preparing the land ( not for Sugar cane ratoons) weeding, irrigation application of fertilizer and other agro chemcals, associated machine time and labour.On top of all that when harvested the land is left bare, may be even for a few months and the soil dries up.Machine also destroys the soil structure, fauna and flora.

On the other hand, canopied plants need capital work once in at least 10 years, fertilizer and agro chemicals maximum upto two years,irrigation say also two years, major machine time once during the life cycle.After the canopy is developed the exposure of the soil to sun's heat is prevented and thus help to keep the soil wet.The droppings from the plants and recycled spent wash should meet all the fertilizer requirement in due course.
The cost labour, collection and transport of feed stock is repetitive during the life cycle with every harvest-same as in the case of corn

Shapiri, Wang and Bruce might look at them more sympathetically

@ John,

Whether one believes that '10% ethanol results in a 1.5% reduction in fuel economy' (one can equally observe that compression-ignition engines, when used with diesel are even more efficient than can be accounted for by differences in thermal density between gasoline and diesel), the fact of the matter is, standard energy-accounting practice expresses different fuels in common energy units, based on their thermal density.

The idea that ethanol production has a positive energy balance" is in total conflict with the two basic laws of thermodynamics which control all processes.
First Law- Energy is neither created or destroyed, it changes from one form to another.
Second Law- The energy available after a
chemical reaction is less than that at the beginning of a reaction; energy conversions are not 100%.
No one as yet has developed a perpetual motion machine but the above claim posits not just a perpetual motion process but a process that actually creates energy by comparing only liquid fuel energy inputs and ignoring all other energy inputs and expenditures to the energy content of the finished product.
If any process produces more energy than the process uses there would be no need for government subsidies of research, development and production.

For those who support the idea that there is a positive energy balance for ethanol perhaps one will sit down and calculate the energy balance in a non-hydrocarbon world using only ethanol as the energy source to produce ethanol, no hydrocarbon based natural gas, gasoline, diesel fuel, lubricants, petrochemicals for rubber, plastics, fertilizer, fuel for the transportation of seeds, planting, growing, fertilizing, harvesting, transporting the raw material, corn for instance, the production, storage, transportation, blending and losses due to solubility in water. To help the energy contents are:
Gasoline- BTU/USG- 114,194
Diesel- BTU/USG- 125,881
Ethanol- BTU/USG- 76,000
The active word is ENERGY and ethanol has only 66% of the energy content of gasoline in BTUs/USG, therefore fewer miles per gallon.
