The non-renewability, ecological issues and health threats connected with the nonrenewable fuel sources has led to exploration of alternative sources of energy to replace the conventional ones. An appealing technology, still in its infancy, that could 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 motors. Vegetables oils like sunflower, rape seed, palm oil, soya bean, Jatropha and so on can be subjected to oil processing to produce biodiesels. It includes no petroleum however can be combined with petroleum diesel for usage or might be utilized in its pure kind.

Developed nations particularly United States and European Countries have already made substantial advances in the Biodiesel Technology. Biodiesel have found its use throughout industries and verticals and could become a perfect cleaner and less expensive alternative to petrol, diesel and fossil fuels. India has also begun exploring the chances to produce and use bio-diesel. A number of plants for biodiesel transesterification are already operating in the nation where veggie oils are reacted 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 renewable and carbon-neutral, therefore having no net influence on the climate. Besides, bio-diesel operates in compression engines similar to regular petroleum diesel and for this reason can be used with little or no engine adjustments. Biodiesel do not need any separate facilities for its storage and can be kept just like the petroleum based fuels.

Considering the growing energy demand in the nation, rising petroleum rates and the ecological risks of fossil fuels, the Indian Government has used up efforts to establish the Bio Diesel Technology in India and set up more oil processing systems. The Government revealed 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 veggie oils like sunflower, soya bean, rape seed, palm oil are utilized as the pre-dominant basic materials for oil processing and biodiesel production but in India the maximum potential to produce biodiesels is from oil - a non-edible one produced from the seeds of the Jatropha jatropha curcas. The greatest advantage of utilizing jatropha curcas as a basic material is that this plant can be grown in huge quantities in wastelands all throughout India requiring really little water in contrast to other cash crops. Once grown, the plant has a useful life expectancy of numerous years. The Jatropha seeds include 40% oil and are thought about to be an excellent source of bio-diesel. The Government of India has actually determined 400,000 square kilometres of land ideal for the jatropha curcas cultivation in the country. India now

A research study estimates that even if a blending effort of 2% jatropha curcas based Biodiesel is accomplished 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 decrease of Green House Gas emission by 3 Million Metric Tonnes (MMT) every year. The government is taking steps to encourage the growing of Jatropha in India supplying free seeds, subsidized loans and other centers. India requires to now strengthen its efforts to make the fullest usage of the Biodiesel Technology. Besides Jatropha, the opportunities for extracting biodiesel from vegetable oils, fats, sunflower, rape seed oil and palm oil ought to also be explored. It will not only supply a response to the challenge of Global Warming however might decrease our dependence on foreign oil and add to our own economy.
