Biofuels: How they stand in different countries - USA: To Reduce dependence on foreign oil Europe: To control greenhouse gas emissions and reduce oil import India: Biodiesel becoming popular- assists in employment creation and in gaining energy independence.
What is Jatropha? Shrub: 2 meters in height Draught resistant, perennial Starts producing after 2-3 years of plantation (produces for 30-35 years) Seeds contain 50% oil (approx. 30% is extractable) Oil: non-edible Seed production: 0.8 to 5.2 tons per acre per annum (depending on soil and irrigation)
How Jatropha-biodiesel and Petro-diesel compare: Low emissions: Reduction in unburned hydrocarbons, CO, SO 2 and particulate matter. Slight increase in NOX Energy content: 94% (~70% for ethanol) Energy Balance: >3.2 (US DOE estimate with soy-biodiesel) Source: Biomass and Bioenergy 31 (2007) 569–575
Economics 1.Farming 2.Oil extraction 3.Transesterification to Biodiesel
Extraction Economics Extraction Units close to cultivation. Extration capacity: 3000 tons/year Oil extracted: ~30%
Biodiesel conversion economics Costs incurred: Personnel, Methanol/Ethanol, Potassium Hydroxide, Utilities, Equipments. Revenue: Biodiesel and Glycerol sales. ROI: 1.5 to 3 years
Breaking the Poverty Cycle Providing Employment: Harvesting is labor intensive. Not eating into the food crop land Extracted oil used directly: electricity generators, farm machines, indoor lighting, etc.
Outlook Indian Railways: all trains run on B5 by 2010 Daimler Chrysler: tie up with production facility in Gujrat; completed 10,000 kms of test runs on the CDI engines TATA Motors biodiesel bus-fleet. Immense interest shown by private investors Villages developing cooperatives
Business/Research Opportunity Solvent extraction of esters from seeds Seed variety for stabilized yield NEB study for Jatropha Electricity production using Jatropha oil Transportation issues
