The non-renewability, environmental issues and health risks related to the nonrenewable fuel sources has resulted in expedition of alternative sources of energy to substitute the conventional ones. An appealing technology, still in its infancy, that could show us the method to the future ahead is Biodiesels. Biodiesels are diesel fuels originated from grease or animal-fat that could be utilized to run diesel engines. Vegetables oils like sunflower, rape seed, palm oil, soya bean, jatropha curcas and so on can be subjected to oil processing to produce biodiesels. It contains no petroleum however can be blended with petroleum diesel for use or could be utilized in its pure form.

Developed nations particularly United States and European Countries have already made considerable advances in the Biodiesel Technology. Biodiesel have discovered its usage throughout industries and verticals and could become a perfect cleaner and less expensive alternative to fuel, diesel and fossil fuels. India has also started checking out the chances to produce and use bio-diesel. A number of plants for biodiesel transesterification are already working in the country where vegetable oils are responded with alcohols (ethanol or methanol usually) to produce bio-diesel.

The primary factor for the increasing need for biodiesels is the fact that biodiesels are renewable and carbon-neutral, hence having no net effect on the climate. Besides, bio-diesel operates in compression engines much like normal petroleum diesel and thus can be used with little or no engine adjustments. Biodiesel do not require any different facilities for its storage and can be stored similar to the petroleum based fuels.

Considering the growing energy need in the nation, rising petroleum costs and the ecological risks of nonrenewable fuel sources, the Indian Government has actually used up initiatives to establish 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 veggie oils like sunflower, soya bean, rape seed, palm oil are used as the pre-dominant raw materials for oil processing and biodiesel production but in India the optimal potential to produce biodiesels is from jatropha curcas oil - a non-edible one produced from the seeds of the Jatropha curcas. The greatest benefit of utilizing jatropha curcas as a raw product is that this plant can be grown in huge quantities in wastelands all throughout India needing really little water in contrast to other money crops. Once grown, the plant has a useful lifespan of a number of years. The jatropha curcas seeds include 40% oil and are thought about to be an exceptional source of bio-diesel. The Government of India has recognized 400,000 square kilometres of land ideal for the jatropha curcas growing in the . India now

A study estimates that even if a mixing initiative of 2% jatropha curcas based Biodiesel is achieved in 2011-12, India will save around Rs. 3000 crores. Besides, it will produce around Rs. 5500 crores in the rural economy and help in reduction of Green House Gas emission by 3 Million Metric Tonnes (MMT) every year. The federal government is taking actions to encourage the growing of Jatropha in India providing complimentary seeds, subsidized loans and other centers. India requires to now reinforce its efforts to make the fullest usage of the Biodiesel Technology. Besides jatropha curcas, the avenues for extracting biodiesel from veggie oils, fats, sunflower, rape seed oil and palm oil ought to also be checked out. It will not just supply an answer to the difficulty of Global Warming but might decrease our dependence on foreign oil and add to our own economy.
