The non-renewability, ecological issues and health dangers connected with the nonrenewable fuel sources has caused exploration of alternative sources of energy to replace the conventional ones. An appealing technology, still in its infancy, that might show us the way to the future ahead is Biodiesels. Biodiesels are diesel fuels stemmed from grease or animal-fat that might be utilized 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 but can be blended with petroleum diesel for use or might be used in its pure type.

Developed nations specifically United States and European Countries have already made significant advances in the Biodiesel Technology. Biodiesel have found its usage across industries and verticals and could emerge as an ideal cleaner and cheaper option to gas, diesel and nonrenewable fuel sources. India has also begun exploring the chances to produce and utilize bio-diesel. A variety of plants for biodiesel transesterification are currently operating in the country where veggie oils are responded with alcohols (ethanol or methanol usually) to produce bio-diesel.

The main reason for the increasing need for biodiesels is the fact that biodiesels are sustainable and carbon-neutral, therefore having no net impact on the environment. Besides, bio-diesel operates in compression engines simply like typical petroleum diesel and thus can be utilized with little or no engine modifications. Biodiesel do not need any separate infrastructure for its storage and can be saved much like the petroleum based fuels.

Considering the growing energy need in the country, increasing petroleum costs and the environmental hazards of fossil fuels, the Indian Government has taken up efforts to the Bio Diesel Technology in India and established more oil processing systems. The Government announced its 'National Biofuel Policy' on 12 September 2008 which intends to meet 20% of India's diesel need with bio-fuels in the coming years.

Globally, edible vegetable oils like sunflower, soya bean, rape seed, palm oil are utilized as the pre-dominant basic materials for oil processing and biodiesel production however in India the maximum potential to produce biodiesels is from Jatropha oil - a non-edible one produced from the seeds of the Jatropha curcas. The most significant advantage of utilizing Jatropha as a raw product is that this plant can be grown in substantial quantities in wastelands all throughout India requiring really little water in contrast to other cash crops. Once grown, the plant has a helpful life expectancy of numerous decades. The Jatropha seeds include 40% oil and are thought about to be an excellent source of bio-diesel. The Government of India has identified 400,000 square kilometres of land appropriate for the Jatropha growing in the nation. India now

A research study approximates that even if a blending effort of 2% Jatropha based Biodiesel is accomplished in 2011-12, India will conserve around Rs. 3000 crores. Besides, it will generate around Rs. 5500 crores in the rural economy and assistance in decrease of Green House Gas emission by 3 Million Metric Tonnes (MMT) every year. The government is taking actions to encourage the cultivation of Jatropha in India providing free seeds, subsidized loans and other centers. India requires to now strengthen its efforts to make the maximum use of the Biodiesel Technology. Besides Jatropha, the opportunities for extracting biodiesel from veggie oils, fats, sunflower, rape seed oil and palm oil ought to likewise be checked out. It will not just offer a response to the challenge of Global Warming but might reduce our dependence on foreign oil and add to our own economy.
