The non-renewability, ecological issues and health dangers connected with the nonrenewable fuel sources has resulted in exploration of alternative sources of energy to replace the conventional ones. An appealing innovation, still in its infancy, that could reveal us the way to the future ahead is Biodiesels. Biodiesels are diesel fuels stemmed from grease or animal-fat that might be used to run diesel engines. Vegetables oils like sunflower, rape seed, palm oil, soya bean, Jatropha and so on can be subjected to oil processing to produce biodiesels. It consists of no petroleum however can be blended with petroleum diesel for use or could be used in its pure type.

Developed countries especially United States and European Countries have already made considerable advances in the Biodiesel Technology. Biodiesel have discovered its usage across industries and verticals and might become an ideal cleaner and more affordable option to fuel, diesel and fossil fuels. India has likewise started checking out the opportunities to produce and utilize bio-diesel. A variety of plants for biodiesel transesterification are already functioning in the nation where veggie oils are reacted with alcohols (ethanol or methanol usually) to produce bio-diesel.

The main reason for the increasing need for biodiesels is the reality that biodiesels are renewable and carbon-neutral, thus having no net effect on the climate. Besides, bio-diesel runs in compression engines similar to regular petroleum diesel and for this reason can be used with little or no engine modifications. Biodiesel do not need any separate facilities for its storage and can be kept much like the petroleum based fuels.

Considering the growing energy demand in the nation, increasing petroleum prices and the ecological dangers of fossil fuels, the Indian Government has used up initiatives to develop the Bio Diesel Technology in India and established more oil processing units. The Government announced its 'National Biofuel Policy' on 12 September 2008 which intends to fulfill 20% of India's diesel demand with bio-fuels in the coming years.

Globally, edible vegetable oils like sunflower, soya bean, rape seed, palm oil are used as the pre-dominant raw products for oil processing and biodiesel production but in India the maximum potential to produce biodiesels is from jatropha curcas oil - a non-edible one produced from the seeds of the Jatropha curcas. The greatest advantage of using as a raw product is that this plant can be grown in big quantities in wastelands all throughout India needing extremely little water in contrast to other cash crops. Once grown, the plant has a beneficial lifespan of several years. The Jatropha seeds consist of 40% oil and are considered to be an exceptional source of bio-diesel. The Government of India has actually identified 400,000 square kilometres of land ideal for the jatropha curcas cultivation in the nation. India now

A research study estimates that even if a mixing effort of 2% jatropha curcas based Biodiesel is accomplished in 2011-12, India will save around Rs. 3000 crores. Besides, it will produce around Rs. 5500 crores in the rural economy and aid in reduction of Green House Gas emission by 3 Million Metric Tonnes (MMT) every year. The federal government is taking actions to motivate the cultivation of Jatropha in India offering complimentary seeds, subsidized loans and other centers. India needs to now strengthen its efforts to make the maximum use of the Biodiesel Technology. Besides jatropha curcas, the opportunities for drawing out biodiesel from vegetable oils, fats, sunflower, rape seed oil and palm oil must also be checked out. It will not only offer an answer to the challenge of Global Warming however might decrease our dependence on foreign oil and add to our own economy.
