The concern over rapid depletion of fossil fuels has prompted the search for alternative fuels having efficiencies similar to those found for the conventional fuels being used today. The present article reviews the prospects and opportunities for using alternative fuels in different...

Developed countries are aspiring to increase the production of biofuels in order to reduce dependence on crude oil and also improve energy security, developing countries such as Ghana can adopt biofuel technologies to provide supports for rural developments. Bioethanol has been identified as one...

Due to rapid growth in population and industrialization, worldwide ethanol demand is increasing continuously. Conventional crops such as corn and sugarcane are unable to meet the global demand of bioethanol production due to their primary value of food and feed. Therefore, lignocellulosic...

The growing need to expand the use of renewable energy sources in a sustainable manner, in order to provide energy supply security and to reduce the environmental impacts associated with fossil fuels, finds in bioethanol an alternative economically feasible and with significant potential of...

Algae are efficient biocatalysts for both capture and conversion of carbon dioxide in the environment. In earlier work, we have optimized the ability of Chlorella vulgaris to rapidly capture CO2 from man-made emission sources by varying environmental growth conditions and bioreactor design. Here...

There is increased interest worldwide in renewable engine fuels as well as in new combustion technologies. Bioethanol is one of the alternative fuels that have been used successfully in spark ignition engines. A combustion technology that currently attracts a lot of interest is the homogeneous...

To reduce the logistical and operating costs for biofuel plants, it is important to make a strategic decision to select the proper site for a new facility. Due to the facility's complexity, the facility-location problem must consider the supply-chain structure, involving the material flow from...

Various biofuels, including bioethanol and biodiesel are technologically being considered replacements for fossil fuels, such as the conventional gasoline and diesel. This paper aims to measure whether economic substitutability can be generated during periods of higher and/or lower prices of...

This paper documents the application of exhaust gas fuel reforming of two alternative fuels, biodiesel and bioethanol, in internal combustion engines. The exhaust gas fuel reforming process is a method of on-board production of hydrogen-rich gas by catalytic reaction of fuel and engine exhaust...

Batch ethanol fermentations using sugarcane juice with immobilised yeast were carried out in shaking flasks in order to investigate the influences of different pH values, temperatures, initial total soluble sugar concentrations and particle stuffing rates on ethanol productivity. The results...
