The non-renewability, environmental issues and health hazards related to the nonrenewable fuel sources has resulted in 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 originated from veggie oil or animal-fat that could be used 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 consists of no petroleum however can be mixed with petroleum diesel for use or could be used in its pure type.

Developed countries particularly United States and European Countries have currently made considerable advances in the Biodiesel Technology. Biodiesel have found its use throughout markets and verticals and could emerge as a perfect cleaner and cheaper alternative to petrol, diesel and nonrenewable fuel sources. India has likewise begun checking out the opportunities to produce and use bio-diesel. A number of plants for biodiesel transesterification are currently working in the nation where vegetable oils are responded with alcohols (ethanol or methanol usually) to produce bio-diesel.

The main factor for the increasing need for biodiesels is the fact that biodiesels are sustainable and carbon-neutral, thus having no net effect on the climate. Besides, bio-diesel runs in compression engines just like regular petroleum diesel and hence 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, increasing petroleum costs and the ecological dangers of nonrenewable fuel sources, the Indian Government has actually taken up efforts to establish the Bio Diesel Technology in India and set up more oil processing units. 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 raw materials for oil processing and biodiesel production but in India the optimal potential to produce biodiesels is from Jatropha oil - a non-edible one produced from the seeds of the Jatropha curcas. The greatest advantage of utilizing Jatropha as a basic material is that this plant can be grown in huge quantities in wastelands all throughout India requiring very little water in contrast to other money crops. Once grown, the plant has a helpful lifespan of several years. The Jatropha seeds include 40% oil and are considered to be an outstanding source of bio-diesel. The Government of India has actually determined 400,000 square kilometres of land suitable for the jatropha curcas growing in the nation. India now

A study estimates that even if a blending effort of 2% jatropha curcas based Biodiesel is accomplished in 2011-12, India will conserve around Rs. 3000 crores. Besides, it will create around Rs. 5500 crores in the 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 growing of jatropha curcas in India providing complimentary seeds, subsidized loans and other facilities. India requires to now enhance its efforts to make the maximum use of the Biodiesel Technology. Besides Jatropha, the avenues for extracting biodiesel from veggie oils, fats, sunflower, rape seed oil and palm oil must likewise be checked out. It will not only provide a response to the obstacle of Global Warming but could decrease our reliance on foreign oil and add to our own economy.
