LONG-TERM GLOBAL OUTLOOK Page 5 of 37
BIOMASS • Currently Fourth largest source of Energy • Supplies 15% of energy use • In developing countries it accounts for 38% of energy use where 50 % of the World population resides Page 6 of 37
AN OVERVIEW ON BIOFUELS • Bio-ethanol • Biodiesel Page 7 of 37
RESOURCES OF BIOMASS • Biomass resource can be divided into three categories: • Energy crops – ethanol, biodiesel • Wastes • Standing forests • Wastes: • Agricultural production wastes • Agricultural processing wastes • Crop residues • Mill wood wastes • Urban organic wastes Page 8 of 37
FUEL PRODUCTS FROM BIOMASS • Bioethanol • Biodiesel (FAME) • Biomethanol • Pyrolytic liquid (Bio-oil) • Hydrogen Page 10 of 37

INDIAN ETHANOL SCENARIO • Auto fuel Policy Report of Expert committee (August 2002) – Development of technologies for producing ethanol and biofuels from different renewable sources for vehicles should be encouraged • September 13, 2002 Notification making 5% Ethanol blending in gasoline mandatory in 9 States (Sugar producing States)& 4 UTs by January1, 2003, extended to Oct-1,2003. • Oct-21, 2004 Notification made blending conditional: Availability • Present requirement and status • Phase I requirements • - around 350 million liters for 9 states and 4 UTs • -500 million liters for whole country • -capacity setup of 500 million liters • Present Status • - About 100 plants with capacity of 1300 million liters Page 12 of 37
Year Sugar (MMT) Molasses (MMT) Ethanol (million liters) Potential Actual 1989-99 15.5 7.1 1597 1320 1999-20 18.2 8.0 1800 1380 2000-01 18.5 8.5 1980 1442 2006-07 24.7 11.3 2540 POTENTIAL AVAILABILITY OF ETHANOL AND MOLASSES IN INDIA • 50% of total production consumed by Chemical Industry Page 13 of 37
ETHANOL BARRIERS & ISSUES • Reliance on single feed stock (molasses) within fluctuating production (sugar cane, water intensive) • Molasses can support only 5 to 7.5% blends • Control on use and price of sugar cane • Competing demand for ethanol – potable / industrial • Other feed stocks – sugar cane, wheat, sweet sorghum, tropical sugar beat Page 14 of 37
BIOETHANOL PRODUCTION FROM BIOMASS • Bio-ethanol is produced by the sugar fermentation process. The sugar is obtained mainly from biomasses like corn, maize and wheat crops, waste straw, willow and popular trees, sawdust, reed canary grass, cord grasses, Jerusalem artichoke, myscanthus and sorghum plants. • Ethanol production from biomass involve two processes; • Recovery of sugar from biomass and • Sugar fermentation to ethanol Page 15 of 37
ROADBLOCKS FOR ETHANOL • Develop Technology both of acid and enzymatic hydrolysis • Cost effective – low cost of enzymes • Well to wheel analysis – energy conversion efficiency • Flexibility for various feed stocks Page 16 of 37
PHYSICO-CHEMICAL PROPERTIES OF GASOLINE AND GASOLINE/ETHANOL BLENDS Page 17 of 37
OBSERVATIONS ON PHYSICO-CHEMICAL PROPERTIES OF BLENDS • Increase in Octane with Ethanol blending offer opportunities to refineries for reducing Benzene and Aromatics • RVP increase with ethanol blending will require removal of lighter components to meet specifications of Vapor Lock Index. • Additional dosage of anti-oxidants will be required as ethanol increases the oxygen content in the blend to meet potential gum specification and engine deposit formation, storage stability. • Addition of corrosion inhibitors shall also be required as blends have been reported to cause problems on carburetor needle and float of two wheelers. Durability of engines comparable with neat gasoline • Startability and driveability of vehicles are satisfactory Page 18 of 37

BIODIESEL: GENERAL PROCESS STEPS Vegetable Oil Methanol Mixing Transesterification 1-3 stages Catalyst (KOH/NaOH) Methanol Recovery Glycerine Separation Crude Glycerine Biodiesel Purification Bio diesel Page 26 of 37
THE IMPORTANT FACTORS TO BE CONSIDERED • Must be able to process variety of vegetable oils without or minimum modifications. • Must be able to process high free fatty containing oils/ feed stocks. • Must be able to process raw both expelled and refined oil. • Process should be environment friendly almost zero effluents. • Able to produce marketable by products glycerin, fatty acids, soap if any. • Must be able to produce fuel grade esters; Biodiesel produced should meet the standard specifications. • The process should be adaptable over a large range of production capacities. Page 27 of 37
MAIN FEATURES OF HETEROGENOUS CATALYST BASED PROCESS • Flexibility for processing variety of vegetable oils separately or mixed. • Tolerance of of free fatty acids • Conversion of free fatty acids present in feed oils to biodiesel • Tolerate water in alcohol • No emulsion or soap formation • Catalyst can be recycled • Biodiesel produced meets the standard specification (ASTM, European or proposed BIS). • Process can be adapted to wide range of production capacities. Page 28of 37
ROADBLOCKS FOR BIODIESEL • Feedstock cost is the most important factor (constitutes 80% of the cost) • Single feed stock- Jatropha curcas- need to be diversified • High quality Jatropha through genetic modification, tissue culture routes to be developed • Difficulty due to varied agro-climatic conditions and uncertainty of likely yields in various regions – threat due to pests, seasonal variations • High growing period of Jatropha curcas plant (about 2- 6 years) • Major threat to agricultural food products such as wheat, rice, etc. as farmers may give priority to Jatropha. Page 29 of 37
ROADBLOCKS FOR BIODIESEL • Huge quantity of byproduct such as cake and glycerin has to be converted into useful products. Expected Production (MMT) Page 30 of 37
POSSIBLE UTILIZATION OF BYPRODUCTS • Glycerol • Conventional Uses • Conversion To Value Added Chemicals • Propane diols • Additives • Lubricants • Polymers / resins, etc. • Seed Cake • Animal Feed (After detoxification) • As Fertilizer • Liquid Fuel (By Pyrolysis) Page 31 of 37

SOCIO-ECONOMIC BENEFITS • Employment Generation in Rural areas • Low capital cost/intensity as compared to Petroleum refinery • Reduction in desertification and green of land mass • Afforestation & reforestation POTENTIAL CDM BENEFITS • 1 tonne of Diesel releases 3.2 tonnes of CO2 • Use of Biodiesel therefore gives a reduction of 2.51 Tonnes of CO2 • For production of 100,000 tonnes per year of BD the CO2 reduction works out to be 251,000 tonnes. • At a price of CER of US$ 5 per tonne of CO2 potential earning of US$1.25 mill per year • For 10 mill tonnes – earning potential for India by the year US$ 125 million ( Rs 565 Cr.) Page 34 of 37
CONCLUSIONS • Biofuels for transport sector is not new. In present context of Energy security and Environmental concerns in the background of depleting fossil fuels and rising crude oil prices a renewed interest has emerged worldwide including most of the countries in Asia. • Use of bio-diesel and ethanol – a natural choice- for transport sector are emerging as promising bio-fuel candidates. Initially, 5% to 10% use of these fuels may be feasible in most Asian Countries • For sustainable Biofuel programmes cost-effective technology developments using variety of indigenous bio-mass sources needs to be considered Page 35 of 37
CONCLUSIONS • For ethanol, besides molasses, starch & cellulosic biomass should be developed. Biodiesel program should consider flexibility for processing variety of vegetable oil along with value added utilization of byproducts; Glycerol & Seed cake • Need to develop a regional – international – cooperation / partnership on use of renewable / biofuels. • CDM needs to be institutionalized to accelerate commercialization • Ultimate solution lies in Energy conservation, Energy Efficiency and Renewable / Biofuel Energy to achieve Sustainable Human Development Page 36 of 37
