Biodiesel

Biodiesel is a synthetic liquid fuel derived from natural fats like vegetal oils or animal fats, and used as a substitute for diesel obtained from petroleum.

In its direct use as substitutes for diesel, vegetable oils are difficult to use in conventional engines due to its high viscosity and low volatility compared to diesel. Therefore, vegetable oils are subjected to a transesterification process obtaining biodiesel and glycerin.

Capacities

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

Results

The biodiesel 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 biodiesel production are quantified. Highest potential sites are located. Production plant location is optimized.
