Soil Carbon and Nitrogen Dynamics Across the Hillslope-Riparian Interface in Adjacent Watersheds with Contrasting Cellulosic Biofuel Systems
… research, particularly energy derived from cellulosic ethanol, which is derived from biomass such as wood and grass. Cellulosic ethanol demonstrates a more promising future as a global energy source than corn-derived ethanol because it does not displace food crops, irrigation is not …

Water requirement for biorefinery to meet the renewable fuel standard in the contiguous United States
Renewable biofuel production requires a considerable amount of water for biofuel conversion. However, it is still unclear how much water is needed in the Contiguous United States (CONUS) to convert feedstocks to biofuels and the associated impacts on local water availabilities. This study addresses …

Multi-criteria lifecycle evaluation of transportation fuels derived from biomass gasification
The development of a domestic biofuel industry has been a major policy thrust of the United States federal government in the first decade of the 21st century. Cellulosic biofuels have been identified as the primary candidate for meeting long term sustainability and energy security goals. In this …

Switching to Switchgrass: Pathways and consequences of bioenergy switchgrass entering the Midwestern landscape
… ambitious goal of producing 60 billion liters of cellulosic biofuel by 2022. Researchers and US Federal Agencies have identified switchgrass (Panicum virgatum L.) as a potential feedstock for next generation biofuels to help meet this goal because of its excellent agronomic and environmental …

Three essays on the links between agriculture and energy policies in the U.S.
… price and expenditure effects of domestic biofuel policies. The results indicate that the cellulosic biofuel sub-mandate alone could increase biomass prices by an average of 50% to 100% over the baseline values. Biomass expenditures by sectors competing with biofuel producers increase by an …

Examining surface energy and moisture balance changes associated with land conversion from annual to perennial biofuel crops
… search for renewable energy. Second-generation cellulosic biofuel feedstocks are being pursued as part of the solution to diversifying both the agro-economic and renewable energy sectors. This land conversion is expected to alter the surface energy balance via albedo changes and shifts in the …

Yield and quality of cool-season perennial grasses for forage and biomass feedstocks in Northeast Colorado
… and rangeland restoration. It is estimated that biofuels could offset 30% of current fossil fuel use. Switchgrass, a C4 grass species, was chosen by the DOE as the model crop for cellulosic biofuel because of the plant's perennial nature, high water use efficiency, wide range of exploitable …

A dynamic analysis of U.S. biofuels policy impact on land use, greenhouse gas emissions and social welfare
Biofuels have been promoted to achieve energy security and as a solution to reducing greenhouse gas (GHG) emissions from the transportation sector. This dissertation presents a framework to examine the extent to which biofuel policies reduce gasoline consumption and GHG emissions and their …

A biogeochemical analysis of Miscanthus x giganteus under nitrogen fertilizer treatments and across multiple soil types
… the production 16 billion gallons of renewable biofuel from cellulosic feedstocks by 2022. To reach production goals, large areas of land in the eastern U.S. will need to be dedicated to cellulosic feedstocks. Miscanthus x giganteus (M. x giganteus) is a perennial grass that is a potential …

A prospective analysis of Brazilian biofuel economy: land use, infrastructure development and fuel pricing policies
… domestic markets but also the global food and biofuel economy. Hence, the complex biofuel policy climate in these countries leaves the public with unclear conclusions about the prospects for supply and trade of agricultural commodities and biofuels. In this dissertation I develop a price …

Synthetic enzymatic pathway conversion of cellulosic biomass to hydrogen
… production of hydrogen from biomass sugars. Lignocellulosic biomass, which includes agricultural residues, energy crops, and industrial waste streams, is an ideal substrate for SyPaB conversion, as it is abundant and cheap, second only to untaxed coal on a $/energy content basis. But the structure …
