The estimated energy efficiencies computed with the spreadsheet are comparable to those obtained with Aspen software. For the model considered, trucking biomass to a central facility without first converting it to PO is estimated to reduce energy efficiency by 1%. Fischer–Tropsch (FT) synthesis of the syngas into diesel fuel.

This syngas is then converted into methanol, and the methanol is converted to gasoline using the methanol-to-gasoline (MTG) process first developed by Exxon Mobil. The biomass is chemically converted to a mixture of syngas components (CO, H 2 , CO 2 , CH 4 , etc.), More specific steps include: Feed Handling & Preparation.

The EPA GHG lifecycle analysis combines a suite of peer-reviewed process models and peer-reviewed economic models of the domestic and international agricultural sectors to determine direct and significant indirect emissions, respectively (GREET, FASOM, FAPRI, Winrock, GTAP, CENTURY, DAYCENT, ASPEN-based models, MOVES and NEMS).
