Tech Stuff: Ethanol Promises
 
Farm-raising our own energy independence: Could it happen?
BY PATRICK BEDARD
July 2006
 
 
You will be hosing ethanol into your gas tank. You will. It’s the law.

The 551-page Energy Policy Act of 2005, signed last August, includes many sops to a blur of special interests, but one single provision rang the bell for automakers, greenies, and farmers, and for a broad coalition of ordinary motorists who were hoping for something, anything, to bring down gasoline prices; starting in 2006, the average gallon of “gas” will contain 2.78-percent ethanol.

Congress has made to the petroleum industry an offer it can’t refuse. It’s called a mandate.

And it’s a mandate that keeps on giving, at least to the farm states, as it ratchets up the ethanol quota, nearly doubling it over the next six years — from 4.0-billion gallons in 2006 to 7.5-billion in 2012.


 
The idea is simple: Use ethanol as the gasoline equivalent of Hamburger Helper. The nation will stretch more miles out of every barrel we import from, as the President says, “unstable parts of the world.” It’s hardly the “energy independence” we’ve been promised for 30 years, but it’s a baby step in that direction.

Or is it? We’ll measure ethanol’s benefits against the promises made for it down the page, but first, a few basics.

Food-crop biofuels given thumbs down
Corn ethanol and soybean biodiesel are not future energy solutions.
Richard Van Noorden

You can squeeze energy from corn, but not enough to displace gasoline.

© Getty
 
Producing biofuels such as ethanol from food crops isn't worth the effort. That's the conclusion of a new and painstaking study published this week in the Proceedings of the National Academy of Sciences1. Researchers should instead concentrate either on producing ethanol from indigestible plant material such as cellulose, or on synthetic hydrocarbon fuels.

The comprehensive study finds that if all the corn (maize) produced in the United States last year were removed from food supplies and turned into ethanol, just 12% of US gasoline demand would be offset. Turning soybeans into diesel would account for only 9% of US diesel demand.

Ethanol's economic viability as a gasoline blending component also depends in part on Federal and States subsidies, and the Federal subsidy (54 cents per gallon) is slated for slow reduction over the next few years and expiration at the end of 2007.

Ethanol can replace gasoline with significant energy savings, comparable impact on greenhouse gases

By Robert Sanders, Media Relations | 26 January 2006

BERKELEY – Putting ethanol instead of gasoline in your tank saves oil and is probably no worse for the environment than burning gasoline, according to a new analysis by researchers at the University of California, Berkeley.

The researchers note, however, that new technologies now in development promise to make ethanol a truly "green" fuel with significantly less environmental impact than gasoline.

Question:

Because ethanol is only 67.52% as compared to gasoline does that mean you will only get 67.52% of the mileage with ethanol that you would get with gasoline?

Does this mean you would want to compare cost per mile before you switched to burning all ethanol?

If the ethanol subsidy is phasing out soon are the new ethanol plants being constructed in Ohio doomed?

Yep, energy can neither be created nor destroyed, only changed in form. Mother Nature offers no free lunches.

You betcha.

Not if the regulation requiring ethanol remains in the books. They have legislated success for the ethanol companies by enforced demand.

Let's assume that you drive a Toyota Camry, the best-selling car in America in 2000. We know that the Toyota Camry with automatic transmission gets 30 miles per gallon of gas on the highway.
Gasoline is more efficient than ethanol. One gallon of gasoline is equal to 1.5 gallons of ethanol. This means that same Camry would only get about 20 miles to the gallon if it were running on ethanol.
We also need to know how far you are traveling: Let's say from Los Angeles to New York, which is 2,774 miles (4,464.2 km), according to MapQuest.com.
Through research performed at Cornell University, we know that 1 acre of land can yield about 7,110 pounds (3,225 kg) of corn, which can be processed into 328 gallons (1240.61 liters) of ethanol. That is about 26.1 pounds (11.84 kg) of corn per gallon.

Ethanol regulations causing gas price spikes

"Some refineries are switching to a formula of gas that requires ethanol, instead of MTBE, and there have been spot shortages of ethanol," he said. "Within 3-4 weeks, refineries completing their transition should be at full production, and as many as 1 million additional barrels of gasoline per day will enter the nation’s supply stream and prices should decline."

http://inthenews.wordpress.com/2006/04/22/...s-price-spikes/


What are the economics? Ethanol can be more economical than the ethers because there is a federal excise tax exemption for its use, and about one-third of the states also offer a tax exemption or other incentive. These incentives are designed to encourage the development of an agriculturally based fuel ethanol industry.

In August 2005, President Bush signed a comprehensive energy bill which included a requirement to increase the production of ethanol and biodiesel from 4 to 7.5 billion US gallons (15 to 28 million m³) within the next ten years. It is expected that in the short term the majority of this increase will come from ethanol produced from corn.

New Ethanol Plants to Be Fueled by Cow Manure
Scott Norris
for National Geographic News

August 18, 2006
While a cheap alternative to gasoline may be pie in the sky, ethanol producers in cattle country will soon be reaping the energy rewards of pies on the ground.

Ethanol production plants fueled by cow manure are under construction in Hereford, Texas, and Mead, Nebraska.

Ethanol could leave the world hungry
One tankful of the latest craze in alternative energy could feed one person for a year, Lester Brown tells Fortune.
By Lester Brown
August 16 2006: 5:39 AM EDT


(Fortune Magazine) -- The growing myth that corn is a cure-all for our energy woes is leading us toward a potentially dangerous global fight for food. While crop-based ethanol -the latest craze in alternative energy - promises a guilt-free way to keep our gas tanks full, the reality is that overuse of our agricultural resources could have consequences even more drastic than, say, being deprived of our SUVs. It could leave much of the world hungry.

We are facing an epic competition between the 800 million motorists who want to protect their mobility and the two billion poorest people in the world who simply want to survive. In effect, supermarkets and service stations are now competing for the same resources.
