Given that the price of ethanol and natural gas contracts maturing at some time in the future, T, there is one corn price that will satisfy the break-even relationship. This is the expected break-even energy value, pt,Tc,EBEV, in Eq. (3). Further, since corn is storable, this long...
So, even before the corn is converted to ethanol, you're spending about $1.05 per gallon. "The energy economics get worse at the processing plants, where the grain is crushed and fermented," reads the Cornell report. The corn has to be processed with various enzymes; yeast is added to ...
