Bioethanol

Ethanol, or ethyl alcohol is a colorless liquid belonging to the family of alcohol which is used as a substitute for gasoline obtained from fossil fuels.

Bioethanol is produced mainly through biochemical processes that involve the hydrolysis of sugar polymers (starch) and their corresponding monomers in the fermentation of sugars to obtain alcohol.

Capacities

A distribution map of higher potential crops for bioethanol production is obtained, and scenarios are developed by using a present land use map. The energy potential of the enegy-giving crops for bioethanol production is calculated at several scales: municipal, district, regional or national. An economic analysis of bioethanol production is also reported. The CO2 emission reduction by the replacement of gasoline with bioethanol is calculated.

Results

The bioethanol potential to cover present and future fuel demand is obtained, as well as its production cost. The installed capacity and the needed surface to achieve a specifed bioethanol production are quantified. Highest potential sites are located. Production plant location is optimized.
