Comment | I had some questions on the above document, related to sugarcane ethanol (Table 26). 1. What is the farming energy in Ca GREE2.0 for sugarcane? It would probably be different for 80% mechanized than 65% mechanized, correct? But if mechanized, there would be some diesel fuel use, so I expected to see some energy use in BTU/ton of cane. 2. What ethanol yield per ton of sugarcane is used in Ca GREET3.0 (gallons per ton)? I noticed that ethanol yield for corn is a required input, but see no reference to that in Table 26 for cane. That would have a significant effect on each plant's CI. Is it a required input, and if so, why does Table 26 not say so? 3. What "N in N2O" percentages are being used in CaGREET3.0 for cane? I note that it is 1.325% for crop residue for corn, and 1.225% for fertilizer for corn. Is it the same numbers in CaGREET3.0 for cane? It is not in Table 26. 4. Are there any yeast or enzymes used to produce ethanol from cane? |
