The non-renewability, environmental concerns and health hazards related to the fossil fuels has actually resulted in expedition of alternative sources of energy to substitute 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 stemmed from grease or animal-fat that could be utilized to run diesel engines. Vegetables oils like sunflower, rape seed, palm oil, soya bean, jatropha curcas etc can be subjected to oil processing to produce biodiesels. It contains no petroleum but can be blended with petroleum diesel for usage or could be utilized in its pure type.

Developed nations especially United States and European Countries have actually already made substantial advances in the Biodiesel Technology. Biodiesel have actually found its usage throughout industries and verticals and might emerge as a perfect cleaner and less expensive alternative to gas, diesel and nonrenewable fuel sources. India has likewise started exploring the opportunities to produce and use bio-diesel. A variety of plants for biodiesel transesterification are already working in the country where veggie oils are reacted with alcohols (ethanol or methanol normally) to produce bio-diesel.

The primary factor for the increasing demand for biodiesels is the fact that biodiesels are renewable and carbon-neutral, therefore having no net influence on the environment. Besides, bio-diesel runs in compression engines just like normal petroleum diesel and hence can be utilized with little or no engine modifications. Biodiesel do not need any separate facilities for its storage and can be kept much like the petroleum based fuels.

Considering the growing energy need in the nation, rising petroleum prices and the ecological threats of nonrenewable fuel sources, the Indian Government has actually taken up efforts to establish the Bio Diesel Technology in India and established more oil processing systems. The Government announced its 'National Biofuel Policy' on 12 September 2008 which intends to fulfill 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 used as the pre-dominant for oil processing and biodiesel production but 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 biggest advantage of utilizing jatropha curcas as a basic material is that this plant can be grown in huge amounts in wastelands all throughout India needing very little water in contrast to other money crops. Once grown, the plant has a useful lifespan of a number of years. The Jatropha seeds contain 40% oil and are thought about to be an exceptional source of bio-diesel. The Government of India has actually determined 400,000 square kilometres of land appropriate for the jatropha curcas growing in the country. India now

A research study approximates that even if a blending initiative of 2% Jatropha based Biodiesel is accomplished in 2011-12, India will conserve around Rs. 3000 crores. Besides, it will generate around Rs. 5500 crores in the rural economy and help in reduction of Green House Gas emission by 3 Million Metric Tonnes (MMT) every year. The government is taking actions to motivate the cultivation of Jatropha in India providing complimentary seeds, subsidized loans and other centers. India requires to now enhance its efforts to make the maximum usage of the Biodiesel Technology. Besides jatropha curcas, the opportunities for drawing out biodiesel from vegetable oils, fats, sunflower, rape seed oil and palm oil ought to also be checked out. It will not just offer a response to the obstacle of Global Warming however might reduce our dependence on foreign oil and contribute to our own economy.
