Carlo simulations (Section S3; SI). Parameter distributions for oil composition, cellulosic pretreatment performance, ethanol production performance, operating days, IRR, co-product prices, and feed prices follow the same assumptions as our previous study. Fuel and electricity prices were updated to include the latest market prices from the USDA Economic Research Service, 10 the U.S. Energy Information Administration, and the U.S. EPA. Latin hypercube sampling was used to generate 5,000 shared scenarios which were used to evaluate each oilcane line and configuration. At each oil content, the competitive biomass yield was characterized across 200 scenarios. Halving the number of scenarios resulted in no significant change in uncertainty and sensitivity results. The sensitivity of the MBSP and carbon intensity to each input parameter was characterized by Spearman's rank-order correlation, a measure of monotonicity between input and output parameters.
