The non-renewability, environmental concerns and health dangers associated with the nonrenewable fuel sources has resulted in expedition of alternative sources of energy to substitute the traditional ones. A promising innovation, 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 and so on can be subjected to oil processing to produce biodiesels. It contains no petroleum however can be blended with petroleum diesel for usage or might be utilized in its pure form.

Developed nations particularly United States and European Countries have currently made considerable advances in the Biodiesel Technology. Biodiesel have actually discovered its use across industries and verticals and might emerge as an ideal cleaner and cheaper alternative to petrol, diesel and fossil fuels. India has actually also begun exploring the opportunities to produce and use bio-diesel. A number of plants for biodiesel transesterification are already operating in the nation where vegetable oils are reacted with alcohols (ethanol or methanol generally) to produce bio-diesel.

The main reason for the increasing need for biodiesels is the reality that biodiesels are renewable and carbon-neutral, therefore having no net effect on the environment. Besides, bio-diesel operates in compression engines simply like normal petroleum diesel and for this reason can be used with little or no engine modifications. Biodiesel do not need any separate infrastructure for its storage and can be kept similar to the petroleum based fuels.

Considering the growing energy need in the nation, increasing petroleum costs and the environmental risks of nonrenewable fuel sources, the Indian has actually taken up efforts to develop 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 demand 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 maximum 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 amounts in wastelands all across India needing really little water in contrast to other cash crops. Once grown, the plant has a helpful life expectancy of a number of decades. The Jatropha seeds contain 40% oil and are considered to be an outstanding source of bio-diesel. The Government of India has actually identified 400,000 square kilometres of land appropriate for the jatropha curcas cultivation in the country. India now

A study estimates that even if a mixing effort of 2% Jatropha based Biodiesel is achieved in 2011-12, India will save around Rs. 3000 crores. Besides, it will produce 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 federal government is taking actions to encourage the cultivation of Jatropha in India supplying totally free seeds, subsidized loans and other centers. India needs to now enhance its efforts to make the max usage of the Biodiesel Technology. Besides jatropha curcas, the avenues for drawing out biodiesel from vegetable oils, fats, sunflower, rape seed oil and palm oil ought to likewise be explored. It will not only offer an answer to the challenge of Global Warming but could reduce our reliance on foreign oil and contribute to our own economy.
