Sam Jackson Southeastern Region GIS Efforts University of Tennessee Office of Bioenergy Programs Knoxville, TN Research Assistant Professor

Overall Efforts/Project  Continuation literature review for data and information in previously conducted studies  Collecting data related new and current feedstock studies in the region (switchgrass, woody biomass, crops, etc)  Significant work on woody biomass availability and siting models done

Biofuels Facility Location Analysis Modeling Endeavor  Brad Wilson, Burt English  Biorefinery site evaluation in 16 southeastern states  Combines:  Suitability analysis based on geographic features  Feedstock supply analysis

Currently focused on switchgrass as the feedstock Uses crop zones derived from SSURGO soils database and county boundaries BIOFLAME

Incorporates: – Transportation networks – roads, rail, barge – Crop yield, budgets, price, and land-use information Model calculates break-even price for crop competition, marginal costs of transportation, and identifies optimal sites BIOFLAME

Input Parameters

Suitability Analysis Showing areas near major roads, railroads, navigable waterways, and major cities

Biorefineries and Feedstock Eight facilities sited across Tennessee with associated feedstock

Site Comparison Output table showing cost breakdown and crop acreages converted to switchgrass production

Expansion to more states and energy feedstocks Increased resolution for crop zones to field level Increased resolution of crop yield information using models like EPIC or ALMANAC Preprocessing/depot collection facilities Addition of: – Policy implication function – Ethanol demand function Ideas for Improvement/Future Plans
