India plans to introduce 20 per cent ethanol blending with petrol in some parts of the country from April next year, a source familiar with the plan said, although the federal government plans a nationwide roll out from 2025-26.

Hit hard by rising oil prices, India has expedited efforts to boost local output of oil and a transition to alternative fuels to cut its import bill.

The source said India has been mixing about 10.5 per cent ethanol with petrol for the last three months.

The government hopes to save up to 500 billion Indian rupees ($6.45 billion) in this fiscal year from ethanol blending.

The world's third biggest oil importer and consumer relies on foreign suppliers for about 85 per cent of its demand.

India's petrol demand is already rising at a brisk pace as people prefer to travel in their own vehicles to avoid a heatwave.

This source said India's petrol demand rose by about 14 per cent in the first half of May from the same period in the previous month, while that of diesel rose by about 2 per cent.

Indian cabinet on Wednesday approved changes in the biofuel policy to bring forward target for 20 per cent ethanol blending with petrol to 2025-26 from 2030, a government statement.

The government has allowed use of more feedstock for production biofuels and their export in 'in specific case'.

So far, India allows use of items such as surplus rice and maize, molasses, sugarcane juice, sugar, and damaged food grains.
