Table 3.
Cost items and MESP for the Reference scenario (1G ethanol) and Scenario A (Base case)
| Reference scenario (1G ethanol) | Scenario A (1G+2G ethanol) | 2G ethanol a for Scenario A | |
|---|---|---|---|
| Ethanol, L/dry ton SC | 284 | 329 | 45 |
| Power production, kWh/dry ton SC | 364 | 185 | -179 |
| Cost items, US$/L | |||
| Sugar cane | 0.230 | 0.198 | 0.000 |
| Enzymes | 0.000 | 0.045 | 0.341 |
| Acid | 0.000 | 0.005 | 0.080 |
| Base | 0.003 | 0.003 | 0.020 |
| Water consumption | 0.003 | 0.008 | 0.045 |
| Other raw materials | 0.008 | 0.005 | 0.000 |
| Labour, maintenance, insurance | 0.040 | 0.055 | 0.148 |
| Electricity export/opportunity cost | -0.111 | -0.050 | 0.357 |
| Vinasse sales | 0.000 | 0.000 | -0.003 |
| Capital cost | 0.095 | 0.156 | 0.560 |
| Minimum Ethanol Selling Price | 0.264 | 0.428 | 1.548 |
a 2G ethanol and power production are obtained as the difference of Scenario A value and the Reference scenario (1G) value. The cost items for 2G ethanol are calculated according to Equation 1.
