BIOFUELBiomassPlants and plant-derived materials.Converted to energy by: Thermal Chemical Bio-Chemical, Conversions.

BiofuelFuel derived from biomass.Can be in three forms:

History of Biodiesel fuelDiesel Engine developed in the 1890s by Rudolph Diesel.Early experimenters on vegetable oil fuels included the French government and Dr. Diesel.Power early diesel engines for agriculture in remote areas of the world, where petroleum was not available at the time.After Dr. Diesels death in 1913 petroleum became widely available in a variety of forms also present diesel fuelWorld War II and the oil crises of the 1970s saw brief interest in using vegetable oils to fuel diesel engines.Environmental impacts also forced to think.Biofuel Generation First Generation:Biofuels are produced directly from food crops by abstracting the oils for use in biodiesel or producing bioethanol through fermentation.Issue of food Vs. fuel.Second Generation:They are produced from non-food crops such as wood, organic waste, food crop waste and specific biomass crops, therefore eliminating the main problem with first generation biofuels.Third Generation:Specially engineered energy crops such as algae as its energy source.Fourth Generation:Fourth Generation Bio-fuels are aimed at not only producing sustainable energy but also a way of capturing and storing CO2.Evolution of present BiodieselNew diesel engines cant run on vegetable oil.Vegetable oil- Viscous nature compared to petroleum diesel fuel.Various methods proposed to decrease the viscosity level.Transesterification -catalyst blending.The fuel is made from various feed stocks including waste vegetable oils and non-edible oils like used cooking oil and acid oils (a waste from edible oil manufacturing process)Jatropha oil seeds

Advantages of JatrophaIt is easy to cultivate jatropha. Jatropha can grow on all the climatic conditions and soils hence it is cultivated in most of the places.It is less expensive to cultivate jatropha and most of the jatropha seed varieties are available of less cost.The percentage of yield is high and the extraction of oil is also maximum.Jatropha provides higher rate of output than any other crops.It is very easy to maintain the jatropha plant even at the seedling stage

Algae to Algae oil

Algae advantagesGreen algae used- high lipid( e.g. fatty acids) content.low-cost, high-energy and entirely renewable feedstock.Produce more energy per acre than conventional crops.Can also be grown using land and water unsuitable for food production.Fuel can be manufactured into a wide range of fuels such as diesel, petrol and jet fuel.Steps of Biodiesel formationSTEP 1.Oil feed stock.STEP 3.Alcohol is added to the oil and, in the presence of a catalyst, produces glycerine and biodiesel.Glycerine is separated from the biodiesel and may be used later in cosmetic or pharmaceutical products.STEP 4.Alcohol is removed through an evaporation or distillation process and reused. The biodiesel is further purified, then stored.STEP 5.Pure biodiesel formed.

Advantages of BiodieselBiodiesel fuel is a renewable energy source.Creates less pollution, estimated that the use of 1 kg of biodiesel leads to the reduction of some 3 kg of CO2.Low sulphur content.Another of the advantages of biodiesel fuel is that it can also be blended with other energy resources and oil.No modification required in existing engine.The lubricating property of the biodiesel may lengthen the lifetime of engines.My Eco EnergyMy Eco Energy(MEE) opened biodiesel retail outlets Pune.Biodiesel brand Indizel @ of Rs 64 a liter.The company has identified three locations for the manufacturing units at Kolhapur, Noida and Visakhapatnam.

Biodiesel

a salvation from the twin evils of high oil prices and climate change.
