“…The corresponding average transport costs are $0.01/L and $0.04/L. Truck transport is dominant in Iowa (29), however facilities with corn transport distances of more than 400 km (250 mi) are likely to use rail due to the cost difference. Subsequent costs presented in this paper assume rail transport.…”

The combination of current and planned 2007 U.S. ethanol production capacity is 50 billion L/yr, one-third of the Energy Independence and Security Act of 2007 (EISA) target of 136 billion L of biofuels by 2022. In this study, we evaluate transportation impacts and infrastructure requirements for the use of E85 (85% ethanol, 15% gasoline) in light-duty vehicles using a combination of corn and cellulosic ethanol. Ethanol distribution is modeled using a linear optimization model. Estimated average delivered ethanol costs, in 2005 dollars, range from $0.29 to $0.62 per liter ($1.3-2.8 per gallon), depending on transportation distance and mode. Emissions from ethanol transport estimated in this work are up to 2 times those in previous ethanol LCA studies and thus lead to larger total life cycle effects. Long-distance transport of ethanol to the end user can negate ethanol's potential economic and environmental benefits relative to gasoline. To reduce costs, we recommend regional concentration of E85 blends for future ethanol production and use.

“…In a survey of 20 ethanol facilities in Iowa, all but one had rail access and the state government is subsidizing spurs to connect facilities to existing lines (29). An ethanol pipeline system would require an optimized combination of main and branch lines to minimize capital and operation costs.…”

“…The quality of corn grain used for ethanol production is typically characterized by its moisture content, damage level, test weight, and mycotoxin content to a lesser extent (Hardy et al, 2006). This information is used to determine if a load of grain meets the criterion for each quality parameter set by the production plant.…”

Current methods for characterization of lignocellulosic biomass feedstocks for biological conversion are dominated by compositional analysis and digestibility/ fermentation tests; however, both these groups of laboratory methods have their respective advantages and disadvantages. The purpose of this paper is to develop a wet-chemistry assay for determination of lignocellulosic biomass quality that combines both compositional analysis and fermentation methods. This assay also should not require expensive or highly specialized laboratory equipment and should be able to be adapted for high throughput applications, such as near infrared reflectance spectroscopy (NIRS)
