Currently, the complexity and scale dependency of land-use decisions and their impacts are not understood, defined, or described with adequate clarity to enable policy makers to develop strategies to ensure a sustainable bioenergy future with acceptable environmental and socioeconomic consequences...

To enzymatically convert biomass to biorefinery feedstock, biofuels, or hydrogen an environmentally friendly solvent or process is needed to disrupt the microstructure of lignocellulosics. In multi-stage processes, solvents are being used as pretreatments by dissolving cellulose and precipitation...

Photocatalysis is the acceleration of a slow reaction by a photon-assisted process with titanium dioxide (TiO2) being the material of choice for most environmental applications including hydrogen production by water splitting [1,3]. Inspite of a number of advantages like optimum band structure,...

The volatility of oil prices, the large proportion of oil importation, and the massive contribution of greenhouse gases from the transportation sector motivates the United States to seek domestic sources of alternative transportation fuels with lower greenhouse emissions. The abundance of coal and...

Oil prices go up and they come down and our ability to forecast them with any real confidence has not been particularly good. A year ago when oil prices were at record highs and global economies were booming, the case for biofuels seemed clear. The path forward is cloudier today. Are we facing a...

Liquid Transportation Fuels from Coal and Biomass Technological Status, Costs, and Environmental Impacts Abstract The U.S. transportation sector consumes about 14 million barrels of oil per day, 9 million of which are used in light-duty vehicles. Total U.S. oil consumption is 20 million barrels per...

The pace of technology improvement and deployment could significantly reduce the cost of stabilizing greenhouse gas concentrations and improve the nation's energy security. Given the need for a large-scale energy transformation, the challenge is to move toward actions that go beyond technology R...

Absolute and per-capita energy consumption is bound to increase globally, leading to a projected increase in energy requirements of 50% by 2020. The primary source for providing a majority of the energy will continue to be fossil fuels. However, an array of enabling technologies needs to be proven...

In today’s competitive environment, development and implementation of new refining technology can differentiate one refining company from another. Whether in processing non-traditional crudes such as oil/tar sands or high sulfur crudes, extracting more from the bottom of the barrel, complying with...

Papers are on topics related sustatinable supply of a wide variety of biomass feedstocks to meet the needs of evolving liquid fuel demand (transportation and heating) and alternative enrgy sources. Please Note : Biomass Thermal Conversion -- Spring Meeting 2009 includes the following recorded...
