  • What should we grow?Ideal CropHigh biomass yieldLow in lignin and high in cellulose and hemicelluloseAble to stand in field to extend harvest windowLow water requirement Low nutrient requirement

  • Perennial CropsSwitchgrassBig BluestemMiscanthus x giganteus

  • Annual CropsCorn (rotated with soybean)Continuous CornPhotoperiod Sensitive SorghumBrown Mid-Rib Sorghum (BMR)Dual Purpose Forage Sorghum

  • ChallengesHarvestingWater RemovalStandabilityDensityWater Usage Ethanol ProductionCrop Production

  • Water Usage3 gallons required per gallon of corn ethanol (RFA)6 gallons required per gallon of cellulosic ethanol (NREL)About 20-25 inches of water are necessary to produce an acre of average yielding corn

  • HarvestingBiomass needs to be at 15% moistureTransportation Greater bulk density required to transport efficiently

  • Cob HarvestingThe next step?Cobs prove to be a good resource in the cellulosic biofuel industryHigher bulk density than stover Leave Less ash when burnedProduce higher BTU per pound.
