Geee Posted January 12, 2012 Share Posted January 12, 2012 Front Page Magazine:As I have noted on more than one occasion, in recent years the United States EPA has been acting more and more like a revenue-generating arm of the government than an agency that’s actually interested in protecting human health and the environment. A recent story published in the New York Times amply illustrates the point: fuel suppliers are being fined for failing to add a “green fuel” – cellulosic ethanol – that doesn’t actually exist into their gasoline blends.Cellulosic ethanol has long been a particularly prized panacea among environmental groups. As any moonshiner knows, conventional ethanol has long been produced by fermenting naturally grown sugars. These sugars are readily available and relatively easy to get at in corn for example, which is why ethanol production plants commonly use corn as their feedstock. However, even Al Gore eventually realized that it was rather idiotic to take millions of acres of farmland out of food and feed production in order to “grow” a fuel that (in many gases) actually ends up on the deficit side of the energy ledger. Cellulosic ethanol theoretically addresses those concernsThere are sugars theoretically available in cellulose, a naturally-occurring polymer found in all sorts of plant life. If you can figure out how to get at those sugars, then you can make ethanol out of things that don’t have a lot of intrinsic value and that don’t compete with food and feed crops, like tree trimmings and corn cobs. Unfortunately, getting at those particular sugars is (for a lot of reasons that would bore the heck out of the average reader) extremely difficult. Like the Chevy Volt, the concept of cellulosic ethanol is very attractive, but the reality is expensive and impractical. Link to comment Share on other sites More sharing options...
