The non-renewability, environmental concerns and health dangers related to the nonrenewable fuel sources has caused expedition of alternative sources of energy to replace the traditional ones. An appealing innovation, still in its infancy, that could show us the method to the future ahead is Biodiesels. Biodiesels are diesel fuels derived from grease or animal-fat that could 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 contains no petroleum however can be blended with petroleum diesel for use or might be utilized in its pure type.

Developed countries specifically United States and European Countries have currently made considerable advances in the Biodiesel Technology. Biodiesel have found its usage throughout industries and verticals and might become a perfect cleaner and more affordable option to gas, diesel and nonrenewable fuel sources. India has actually also started exploring the chances to produce and utilize bio-diesel. A number of plants for biodiesel transesterification are currently working in the country where vegetable oils are reacted with alcohols (ethanol or methanol generally) to produce bio-diesel.

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

Considering the growing energy demand in the nation, increasing petroleum prices and the ecological threats of nonrenewable fuel sources, the Indian Government has used up efforts 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 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 raw products for oil processing and biodiesel production however in India the optimal capacity to produce biodiesels is from Jatropha oil - a non-edible one produced from the seeds of the Jatropha curcas. The greatest advantage of using Jatropha as a basic material is that this plant can be grown in substantial amounts in wastelands all throughout India requiring extremely little water in contrast to other money crops. Once grown, the plant has a beneficial lifespan of a number of decades. The Jatropha seeds include 40% oil and are considered to be an outstanding source of bio-diesel. The Government of India has determined 400,000 square kilometres of land suitable for the jatropha curcas cultivation in the nation. India now

A research study estimates that even if a blending initiative of 2% Jatropha based Biodiesel is achieved in 2011-12, India will save around Rs. 3000 crores. Besides, it will create around Rs. 5500 crores in the rural economy and help in decrease of Green House Gas emission by 3 Million Metric Tonnes (MMT) every year. The federal government is taking actions to motivate the growing of Jatropha in India providing complimentary seeds, subsidized loans and other . India needs to now strengthen its efforts to make the fullest use of the Biodiesel Technology. Besides Jatropha, the opportunities for drawing out biodiesel from vegetable oils, fats, sunflower, rape seed oil and palm oil should also be checked out. It will not only supply a response to the challenge of Global Warming but might reduce our dependence on foreign oil and contribute to our own economy.
