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

• 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

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

Biorefineries and Feedstock
Eight facilities sited across Tennessee with associated feedstock

• 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
