Bangalore, Jun 18 (UNI) The Union government is contemplating to increase the content of Ethanol blending with Petrol from the present 5 per cent to 10 per cent, Dr R Chidambaram, Principal Scientific Advisor, said today.
Delivering a special address at the 'Clean Air Summit', jointly organised by Bosch Group and Die Deutsche Gasellschaftfuir Technische Zusammenarbeit (GTZ) here, he said the government had allowed ethanol blending of up 5 per cent in nine states.
Calling upon the scientists and researchers to carry out studies on the combustion characteristics of motor engines for the blending of a higher content of ethanol in petrol, Dr Chidambaram said that, the depletion of fossil fuels and skyrocketing price of crude oil, the focus on the increased use of biofuels will be inevitable.
He cautioned that increase in biofuel production should not affect the country's food security. Jathropa and other plants, the sources of biofuels should be encouraged to be grown in wastelands.
"The cellulosic ethanol should be procured only from agricultural residues," he said.
He said hydrogen had the potential to replace fossil fuel in the future. However it involved a higher cost production as it was not a primary fuel.
Dr Chidambaram said the boom in the automobile sector, the problem of auto-waste had assumed serious proportions. However this could be worked to an advantage as recycling could lead to considerable energy savings.
It was estimated that by 2020, annually the recoverable materials would be of the order of 1.5 million tons of steel, 180,000 tons of aluminium and 75,000 tons each of rubber and plastics.
"Recycling of one kg of aluminium requires only seven per cent of the energy required for production of primary aluminium," he said.
Stating that country was already on a sustainable energy path, he said globally competitive technologies and management practices adopted by the Indian Industry had led to the energy intensity of processes coming down steadily over the past three decades.
"The fossil fuel carbon-dioxide intensity of the Indian economy in the year 2004 was the same as that of Japan and better than that of Germany, at a much lower level of per-capita GDP according to World Bank data," he said.
While acknowledging that over the years a great deal of research had been done on reducing pollutants in automotive emissions due to stringent regulations, he opined that Indian standards of regulations was now close to standards in the developed countries.
"We also need better enforcement of these regulations," he added.
