Supply Chain Sustainability Analysis of Three Biofuel Pathways: Biochemical Conversion of Corn Stover to Ethanol; Indirect Gasification of Southern Pine to Ethanol; Pyrolysis of Hybrid Poplar to Hydrocarbon Fuels (Citation Only)

In this supply chain report, we consider three biofuel pathways and use parameters the National Renewable Energy Laboratory (NREL), Idaho National Laboratory (INL), and the Pacific Northwest National Laboratory (PNNL) developed in SOT analyses of three biofuel pathways. All parameters were incorporated into Argonne National Laboratory's Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET [TM] ) model to determine the full supply chain impacts (Argonne National Laboratory, 2013). For example, GREET calculates the total energy consumption associated with natural gas consumed at a biorefinery as the energy inherent in the natural gas in addition to the energy consumed during natural gas recovery, processing, and transmission and distribution. In particular, a GREET version has been developed through this effort.
