The non-renewability, environmental concerns and health dangers associated with the fossil fuels has actually caused expedition of alternative sources of energy to substitute the conventional ones. An appealing technology, still in its infancy, that might show us the method to the future ahead is Biodiesels. Biodiesels are diesel fuels originated from vegetable oil or animal-fat that could be used to run diesel engines. Vegetables oils like sunflower, rape seed, palm oil, soya bean, Jatropha etc can be subjected to oil processing to produce biodiesels. It contains no petroleum but can be combined with petroleum diesel for use or might be used in its pure form.

Developed countries especially United States and European Countries have already made substantial advances in the Biodiesel Technology. Biodiesel have discovered its use throughout markets and verticals and might become an ideal cleaner and cheaper alternative to gas, diesel and fossil fuels. India has likewise started exploring the chances to produce and utilize bio-diesel. A variety of plants for biodiesel transesterification are already functioning in the nation where vegetable oils are responded with alcohols (ethanol or methanol normally) to produce bio-diesel.

The main reason for the increasing need for biodiesels is the fact that biodiesels are renewable and carbon-neutral, thus having no net influence on the environment. Besides, bio-diesel runs in compression engines just like regular petroleum diesel and for this reason can be utilized with little or no engine adjustments. Biodiesel do not need any different infrastructure for its storage and can be stored similar to the petroleum based fuels.

Considering the growing energy need in the country, rising petroleum prices and the environmental dangers of nonrenewable fuel sources, the Indian Government has actually used up efforts to establish the Bio Diesel Technology in India and established more oil processing systems. The Government revealed its 'National Biofuel Policy' on 12 September 2008 which aims 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 capacity to produce biodiesels is from Jatropha oil - a non-edible one produced from the seeds of the Jatropha curcas. The most significant benefit of utilizing Jatropha as a basic material is that this plant can be grown in substantial quantities in wastelands all throughout India requiring very little water in comparison to other money crops. Once grown, the plant has a beneficial life expectancy of numerous years. The Jatropha seeds consist of 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 cultivation in the nation. India now

A research study estimates that even if a mixing initiative of 2% Jatropha based Biodiesel is achieved in 2011-12, India will save around Rs. 3000 crores. Besides, it will generate 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 free seeds, subsidized loans and other facilities. India needs to now strengthen its efforts to make the maximum use of the Biodiesel Technology. Besides Jatropha, the opportunities for drawing out biodiesel from vegetable oils, fats, sunflower, rape seed oil and need to also be checked out. It will not only supply a response to the obstacle of Global Warming however could decrease our dependence on foreign oil and add to our own economy.
