Dept. of Energy Rejects Corn Fuel Future
eldavojohn writes "The United States' Department of Energy is stating that corn based fuel is not the future. From the article, "I'm not going to predict what the price of corn is going to do, but I will tell you the future of biofuels is not based on corn," U.S. Deputy Energy Secretary Clay Sell said in an interview. Output of U.S. ethanol, which is mostly made from corn, is expected to jump in 2007 from 5.6 billion gallons per year to 8 billion gpy, as nearly 80 bio-refineries sprout up. In related news, Fidel Castro is blasting the production of corn fuel as a blatant waste of food that would otherwise feed 3 billion people who will die of hunger."
Sugar cane ethanol is the viable alternative, if you are going to use biomass based fuel. Brazil is doing it since the seventies, it already works on most cars that use gas with little to no modification (Fiat, GM and other auto companies already produces them in quantities there) and it is almost a closed cycle, using barely to no fossil fuel on its production. This (warning, PDF) is a good summary on the benefits of sugar cane ethanol, of course we can wait for hydrogen or whatever is the technology of the future, just like we are waiting since the seventies, but if you want something that already works, sugar cane ethanol is the way to go.
Do you know that the only reason that makes U.S. not to get more ethanol from Brazil is protectionism via subsides and import quotas? Fidel got it right on this one, in order to protect the few (and rich) local corn farmers (not to mention the oil barons), U.S. impedes cheap sugar and ethanol to reach the U.S., artificially increasing the demand of corn for ethanol production, driving corn prices up and, this way, making things harder for poor people on U.S. itself and, indirectly, on Mexico too (thanks Nafta). Check this article and see, it is past the point of speculation and conspiracy theories.
Law of unintended consequences in action here. It could be different. Unfortunately, I'm not a citizen of U.S., so, I'm not part of the democratic process there. But a lot of you are, and only you could make the difference. You can wait for the Tesla electric car all your lives (maybe it will fly too, if you wait time enough) while complaining about dependence on fossil fuels and financing wars on it, or you can make the difference now and take a stand on it.
The European Union continues to subsidize thousands of farmers, allowing them to produce huge amounts of surplus food every year that costs EU taxpayers a fortune. There is no political will to curb this waste as (especially in France) the farmers have too much political clout). So, there is no need to consider planting new crops specifically for fuel. The resources already exist, though greater efficiency may come from changing the crops EU farmers currently grow to ones more suitable for biofuels. Growing crops in the EU for biofuel, therefore, could solve two problems contemporaniously: EU waste converted into much needed fuel. Alternativly we could all scrap our cars and take the bus!
Furthermore, we already use too much corn (not the best choice of words, but I'll explain what I mean). Besides the corn we eat in its regular form, corn syrup and other corn derivatives are used in a large portion of our diets in the US. Also, corn is used as the vast majority of feed (estimated at 92% in 2003) for livestock. Corn is a major part of our entire food infrastructure. We are already in serious danger if a corn famine ever arose, but the effects would compound if we base our fuel on corn as well. Diversification is important for any country, especially with an economy as large as the US. Of course, this might never happen, but we all know it's possible (Ireland). By the way, I live in Illinois in a small town of 4000 people surrounded by corn fields. I'm not saying this because I hate corn, but dependence on a single crop is a thin line to walk.
But ethanol is such a poor fuel compared to biodiesel I am amazed it gets the attention it does.
There's no technical reason for it. It is pure politics and the media exploiting(mocking) the anger with the petroleum companies. And it's putting more rainforests at risk. I don't what it does to the soil. I'm sure it will make Monsanto rich. As long as we continue using our present day jalopies, biodiesel is the one true fuel for rapid oxidation. And for the best bang for the buck(best yield per acre), algae is the way to go(about half way down the page). Heck you can grow the stuff in(on) the ocean. No need to use up valuable real estate, but in case you want to anyway, "More recent studies using a species of algae with up to 50% oil content have concluded that only 28,000 km or 0.3% of the land area of the US could be utilized to produce enough biodiesel to replace all transportation fuel the country currently utilizes. Furthermore, otherwise unused desert land (which receives high solar radiation) could be most effective for growing the algae, and the algae could utilize farm waste and excess CO2 from factories to help speed the growth of the algae."
What?
Not everywhere is like the land of the plenty were the supermarkets are stocked with food.
Yeah, well it would be if everybody would stop shooting at each other for a second.
What?
When I went to college (in Morris, Minnesota) there was an ethanol plant in town and I researched ethanol production just to provide some context to the awful smell (think rotting sileage) that hit my apartment complex when the wind was right. Even back in 1990 there was little justification to use ethanol because of the high energy use for production, the increased end-unit costs because of the need to blend at the POS (because ethanol absorbs water it needs to be mixed into the blend near the end delivery point) and the other implications for vehicles (reduced power/volume, injection issues, etc). The investment that the government has made has been misplaced. It purely subsidizes this waste instead of promoting the development of more efficient production/end product. The plant in Morris is still producing the exact same product in the exact same way, the only difference is now (16 years later) they are making money hand over fist.
Finally, corn requires a tremendous amount of water to grow. When we grew corn we didn't irrigate but big corporate farms cannot resist. The Oglalla aquifer is draining, which is a big deal. Irrigation for crops of all sorts are the primary culprit but the impact is larger -- most of the 'breadbasket' of the US is dependent in many ways on the viability of the Oglalla aquifer.
I am stunned and pleased that the DOE has stepped up and stated what should be the obvious. I hope that people following the stories realize that subsidies without measurable and definable goals have no place in our "free trade" economy (tongue in cheek there).
