Feedstock Readiness Level (FSRL) evaluation: Pennisetum purpureum (napiergrass), Alcohol-to-Jet, Southeast, June 2018

    Feedstock readiness level evaluations are performed for a specific feedstock-conversion process combination and for a particular region. FSRL evaluations complement evaluations of Fuel Readiness Level (FRL) and environmental progress. The data from this evaluation, compiled in June 2018, assesses the maturity of *Pennisetum purpureum* (napiergrass) as a feedstock for the Alcohol-to-Jet conversion process in the United States Southeast region.

    Feedstock Readiness Level (FSRL) evaluation: Panicum virgatum (switchgrass), Alcohol-to-Jet, Southeast, June 2018

      Feedstock readiness level evaluations are performed for a specific feedstock-conversion process combination and for a particular region. FSRL evaluations complement evaluations of Fuel Readiness Level (FRL) and environmental progress. The data from this evaluation, compiled in June 2018, assesses the maturity of *Panicum virgatum* (switchgrass) as a feedstock for the Alcohol-to-Jet conversion process in the United States Southeast region.

            Feedstock Readiness Level (FSRL) evaluation: Saccharum officinarum (sugarcane), SIP and Alcohol-to-Jet, Hawaii, June 2018

              Feedstock readiness level evaluations are performed for a specific feedstock-conversion process combination and for a particular region. FSRL evaluations complement evaluations of Fuel Readiness Level (FRL) and environmental progress. The data from this evaluation, compiled in June 2018, assesses the maturity of *Saccharum officinarum* (sugarcane), as a feedstock for the the Hydroprocessed Fermented Sugars to Synthetic Isoparaffins (HFS-SIP) and/or Alcohol-to-Jet conversion process in the United States Hawaii region.

              Data from: Comparative farm-gate life cycle assessment of oilseed feedstocks in the Northern Great plains

                This MS Word document contains the oilseed feedstock farm-gate model inventories, results, and uncertainty analyses for the Northern Great Plains discussed in Moeller et. al 2017. Analysis was conducted using IPCC GHG standardized emissions. Methodology is detailed in the associated publication (doi: 10.1007/s41247-017-0030-3). The supplementary information contains the names of the ecoinvent inventories; oilseed yield, seeding rates, and fertilization rates per USDA crop management zone (CMZ); climate change, freshwater eutrophication, and marine eutrophication percent contributions ReCiPe results per CMZ; Monte Carlo uncertainty results per CMZ; and farm-gate energy balance analysis results per CMZ.

                Data from: Switchgrass cultivar, yield, and nutrient removal responses to harvest timing

                  Objectives for this study were to compare switchgrass yields from 2010–2011 on eight widely used and experimental upland and lowland genotype (whole plot) at two locations in Tennessee, to determine: (i) which harvest timing (split-plot) provides maximum yield; (ii) effects of harvest timing (mid-Sep, Oct, Nov, and late Oct) on overall total P and K removal; and, (iii) how results are affected by cultivar.

                  Switchgrass ESTs and SNPs

                    As part of our project, “Developing Association Mapping in Polyploid Perennial Biofuel Grasses” (DOE-USDA Plant Feedstock Genomics for Bioenergy Program grant DE-A102-07ER64454)*, two SNP discovery initiatives were carried out. The earlier one (2009) was an approach based on EST sequences. The latest initiative (2011-12) adopted a more powerful approach, based on GBS (Genotyping by Sequencing). We believe that the SNP markers identified in these studies will greatly enhance breeding efforts that target the improvement of key biofuel traits and the development of new switchgrass cultivars.
