- The base values for all parameters were taken from the 2011 Design Report[39]. Uncertainties for feedstock composition were taken from[34]. Uncertainties in calculated yield values are from this work. Using normal distributions of these feedstock composition and calculated yield values, we estimate a mode of $2.17/gal for the MESP with an uncertainty of $0.15/gal.
