Entry of Alternative Fuels in a Volatile U.S. Gasoline Market AgEcon
Vedenov, Dmitry V.; Duffield, James A.; Wetzstein, Michael E..
Dramatic increases in levels and volatility of gasoline prices observed in recent years may create market incentives for adoption of alternative fuels characterized by lower price volatility. This hypothesis is investigated by applying the real-options pricing approach to develop optimal thresholds for switching from conventional gasoline to alternative fuels such as ethanol blends. The main result of the paper is that given the historical price patterns of conventional gasoline and ethanol, switching to ethanol blends is an economically sound decision provided this does not decrease efficiency of the vehicle. Analysis of data subsamples during the periods of higher volatility of gasoline prices (Gulf War and War on Terrorism) provides even stronger...

Performance of an agricultural engine using mineral diesel and ethanol fuels Ciência Rural
Farias,Marcelo Silveira de; Schlosser,José Fernando; Russini,Alexandre; Frantz,Ulisses Giacomini; Estrada,Javier Solis.
ABSTRACT: The global demand for alternatives for mineral diesel oil is growing due to the need for satisfying sustainability and environmental requirements, forcing industries and research institutions to develop new alternative fuels. The objective of this study was to evaluate the performance parameters of an agricultural engine using two different fuels: mineral diesel oil and ethanol. The experiment was conducted on a dynamometric stand using two engines for agricultural use but with a modified fuel injection system, suitable for both diesel and ethanol, in the speed range 1200-2300rpm. The performance of the engines was analyzed considering the power take-off from the tractors for each fuel, as established in the standard NBR ISO 1585. The data...

The Economics Of Growing And Delivering Cellulosic Feedstocks In The Beaumont, Texas Area AgEcon
Fumasi, Roland J.; Richardson, James W.; Outlaw, Joe L..
We estimate the contract prices that must be paid to grow cellulosic energy crops, and the costs of harvesting and transporting those crops in the Beaumont, TX area. Results indicate that the delivered price would range between $54 and $101 per ton of dry matter depending on the specific crop.

U.S. Biodiesel Development: New Markets for Conventional and Genetically Modified Agricultural Products AgEcon
Duffield, James A.; Shapouri, Hosein; Graboski, Michael S.; McCormick, Robert; Wilson, Richard.
With environmental and energy source concerns on the rise, using agricultural fats and oils as fuel in diesel engines has captured increasing attention. Substituting petroleum diesel with biodiesel may reduce air emissions, increase the domestic supply of fuel, and create new markets for farmers. U.S. agricultural fats and oils could support a large amount of biodiesel, but high production costs and competing uses for biodiesel feedstocks will likely prevent mass adoption of biodiesel fuel. Higher-priced niche markets could develop for biodiesels as a result of environmental regulations. Biodiesel has many environmental advantages relative to petroleum diesel, such as lower CO, CO2, SOx, and particulate matter emissions. Enhancing fuel properties by...
