We intentionally varied the oil content in oilcane for uncertainty and sensitivity analyses, specifically examining the impacts of market conditions, design decisions, and potential longterm technological performance. To characterize the implications across the spectrum of observed oil content and yields, we varied oil content uniformly from 1.8 to 5.4 % and biomass yield uniformly from 4.87 to 25.62 dry MT•ha -1 (the low yield from oilcane 1580 and the high yield from sugarcane). We modeled the effect of oil content on the overall composition in manner that was consistent with previously published work. Briefly, an energy balance approach was used to balance an increase in oil content with a decrease in sucrose content.
