Â
Can we expect ethanol production from corn to make serious inroads on the oil import and greenhouse gas emissions problems? Currently, ethanol represents about 5% of U.S gasoline consumption. This could rise to 20% if the country’s entire corn crop were devoted to ethanol production – an impossible assumption, given the importance of corn for animal feed and export. With some 85 billion acres devoted to corn harvest in the United States, there is little suitable farmland for significant expansion.
Â
Another issue is the energy efficiency of the corn based ethanol. For corn based ethanol, fossil fuel energy is required to produce the corn (fertilizer, pesticides, farm machinery), to transport it, and to operate the ethanol plant. A recent analysis has calculated that using ethanol instead of gasoline reduces greenhouse gas emissions, mile for mile, by only 13%. However, some biofuel critics argue that if new land is cleared of its forests or grasslands, the carbon emissions from the land use change should be added to the debit from fossil fuel greenhouse gas emissions. When this is done, corn-based ethanol is a net loser in its impact on climate change. Thus, it could be reasoned that the primary strategy in using corn-based ethanol is to reduce our reliance on imported oil.
Â
Second Generation Biofuel: A more likely long-run technology for producing ethanol in the use of cellulosic feed-stocks such as agricultural crop residues, grasses (such as switchgrass), logging residues, fast growing trees, and fuel woods from forests. Ethanol produced this way is called second – generation biofuel (current starch based processes produce first – generation biofuel). One crop with exceptional potential is Miscanthus, a giant perennial grass that can be grown on poor soil and that out produces corn and other grasses.
Â
With the use of enzymes to break down the cellulose to sugars, demonstration facilities have shown that cellulosic feedstock technology can be a cheaper and more energy efficient process than corn based production. The technology can be cheaper and more energy – efficient process than corn based production. The technology is now being scaled up to commercial production; at least 11 plants are under construction in the United States, and 1 plant in Louisiana has begun production ...
