Niche Markets

There are also many smaller niche markets where ethanol can be utilized. They are considered niche markets because they are much smaller than the general trans­portation fuel market. However, they can still create a considerable demand, espe­cially for a much smaller fuel-producing industry like ethanol. Opportunities exist as ethanol-blended diesel fuel, as a hydrogen source for fuel cells, as an […]

A more near-term niche market for ethanol is aviation. Aviation fuel only accounts for about 5 % of the total transportation fuel use in the United States; it still repre­sents a sizable market for ethanol consumption (approximately 400 million gallons per year). Currently, ethanol is used in some small engine crafts and by experi­mental aircraft pilots (Caddet 1997; Higdon 1997; […]

The Thai government is pursuing a policy of increasing consumption of biodiesel and ethanol produced domestically from cassava. One of its initial steps is to replace the octane-enhancing additive MTBE in gasoline with ethanol. Large-scale produc­tion of fuel ethanol production has started with molasses, but cassava was officially designated the prime raw material. Thailand is a large producer of cassava. […]

Advances in Bioethanol

Disadvantages of fossil fuel derived transportation fuels (greenhouse gas emissions, pollution, resource depletion, unbalanced supply-demand relations) are strongly reduced or even absent with biotransportation fuels. Of all biofuels, ethanol is already produced on a fair scale. It produces slightly less greenhouse emissions than fossil fuel (carbon dioxide is recycled from the atmosphere to produce biomass); can replace harmful fuel additives […]

1.1 Background Energy consumption has increased steadily over the last century as the world population has grown and more countries have become industrialized. Crude oil has been the major resource to meet the increased energy demand. Campbell and Laherrere (1998) used several techniques to estimate the current known crude oil reserves and the reserves as yet undiscovered. They predicted that […]
