Objectives

Develop information on regional supply chains 

Provide holistic evaluation of alternative jet fuel production including feedstock, transportation, and conversion

Evaluate sustainability from environmental, economic and societal perspectives 

Develop scenarios of future alternative jet fuel production 

Identify the key barriers in regional supply chains that must be overcome 

to produce 1 billion gallons of alternative jet fuel by 2018 and

an order of magnitude larger production in the longer term

Support International Civil Aviation Organization (ICAO Committee on Aviation Environmental Protection (CAEP) Alternative Fuel Task Force (AFTF)

Biorefinery Infrastructure Inventory

Inventory existing infrastructure

Retrofit or co-locate with existing facilities

Benefits:

Reuse existing equipment and infrastructure = decreased Capital Expense

Existing skilled workforce in place = jobs saved and created

Environmental (air, water) permits and water rights = decreased start-up delays

Proximity to feedstock

Existing transportation systems

Volpe Alternative Fuels Transportation Optimization Tool (AFTOT)

Optimizes routing to minimize scenario “cost” based on:

Transportation costs

Feedstock supply

Biorefinery capacity (minimum, maximum)

Facility capital cost

Demand

Selects biorefineries 

Material exiting biorefinery depends on processing details

Federal Aviation

<Presentation Title – Change on Master Slide>

Allocates starting material to waypoints (biorefineries) and end points based on total cost, including capex to build new facilities (no capex for existing/fixed facilities), minimum volume for facility, feedstock transport distance, and weighted routing cost.  Special note that can incorporate various weightings and aspects to adjust outcome.  Can explore the space by adjusting things like cost sfor a given mode to evaluate what would turn on a particular rought.  Changing price points so that a particular mode becomes more economical.  Distiance (scale of scenario) will also play important role in determining relative benefit of different modes.

Next Steps for FY15 onward

Support development of life cycle analysis methodology for alternative jet fuels within global market based measure for international aviation 

Project provides a framework to: 

Collect data on regional supply chains 

Conduct regional and national supply chain analyses 

Create production scenarios 

Evaluate alternative jet fuel sustainability

Identify barriers to alternative jet fuel production 

Expanding analysis framework to include:

Waste streams (e.g., municipal solid waste)

Tropical feedstocks (leverage work examining Hawaiian Islands)
