"Haven't run across any numbers for that yet .. " Damn; you just had to say that. Cellulosic EtOh; I've found a few numbers... But yield isn't the same as EROEI. That's given somewhere in the article, I think. Or another I didn't link. Not a lot of data. Using corn as an example, out of the 4.5 tons of grain yielded by one acre of corn, three tons is starch that can be converted to 400 gallons of ethanol with current processing methods; but using using corn stalks and leaves in addition to the corn grain, that same acre would yield 700 gallons of ethanol. (I ran across this one in my alumni mag a few weeks ago. Axed RR about it, but only got answers from others...) Another potential energy crop is miscanthus, a relative of sugarcane, which is being studied by the University of Illinois for its cellulosic bioenergy potential. It has been evaluated in Europe during the past 5-10 years as a new bioenergy crop.Like switchgrass, miscanthus requires minimal water and fertilizer and thrives in untilled fields, but yields more ethanol per acre (1.500 gallons) than switchgrass. seco.cpa.state.tx.us Good night.
