Greater decarbonization at a lower cost is achievable by burying biomass (such as corn or sugarcane) rather than converting it into bio-ethanol.
This model captures the economics. Detailed costs are estimated for biomass burial and to compare the relative CO2 footprints of the two options.
Three individual tabs illustrate margins, NPVs and IRRs for sugar-cane to bio-ethanol economics, buried sugarcane, and buried napier grass.
