The National Renewable Energy Laboratory (NREL) originally developed this application for biopower with funding from the Environmental Protection Agency's Blue Skyways Collaborative. The Department of Energy's Office of Biomass Program provided funding for biofuels functionality.

Alternative Fuel Infrastructure Expansion: Costs, Resources, Production Capacity, and Retail Availability for Low-Carbon Scenarios
The petroleum-based transportation fuel system is complex and highly developed, in contrast to the nascent low-petroleum, low-carbon alternative fuel system. This report examines how expansion of the low-carbon transportation fuel infrastructure could contribute to deep reductions in petroleum use and greenhouse gas (GHG) emissions across the U.S. transportation sector.
Using densified biomass to produce biofuels has the potential to reduce the cost of delivering biomass to biorefineries. Densified biomass has physical properties similar to grain, and therefore, the transportation system in support of delivering densified biomass to a biorenery is expected to emulate the current grain transportation system. By analyzing transportation costs for products like grain and woodchips, this paper identifies the main factors that impact the delivery cost of densified biomass and quantifies those factors’ impact on transportation costs.

This presentation provides an overview of biorefineries in the U.S. The presentation was given at the 1st Brazilian National Refinery Symposium (SNBr) At EMBRAPA
Brasilia, DF, Brazil. September 29, 2011.
This document provides an overview of the National Bioenergy Routing model that is integrated within the Bioenergy KDF.
Transportation fuels are the major component of our energy portfolio. Of the 20 million barrels of petroleum consumed each day in the United States, 68 percent is used in the transportation sector. The Western states are in position to become key producers and beneficiaries in the emerging alternative-fuels economy. We have abundant resources that have great potential as domestic sources for transportation fuels.
Towards Standardization of Life-Cycle Metrics for Biofuels: Greenhouse Gas Emissions Mitigation and Net Energy Yield
Despite a rapid worldwide expansion of the biofuel industry, there is a lack of consensus within the
scientific community about the potential of biofuels to reduce reliance on petroleum and decrease
greenhouse gas (GHG) emissions. Although life cycle assessment provides a means to quantify
these potential benefits and environmental impacts, existing methods limit direct comparison within
and between different biofuel systems because of inconsistencies in performance metrics, system
