"In a major eco-friendly step towards renewable energy generation in India, seaweed sourced ethanol (ethyl alcohol), a biofuel additive in transport fuel, has been used to run a car for the first time. Central Salt and Marine Chemicals Research Institute (CSMCRI) in Bhavnagar scientists recently drove an ambassador car with a fuel blend of 10 per cent ethanol and 90 per cent petrol.
While this green fuel is already produced and used to run cars in some countries, specially US and Brazil, in India, this was not possible as sugarcane, the main source of ethanol, is a food crop here. To counter this disadvantage, CSMCRI has become the first Indian body to successfully produce ethanol from a seaweed, Kappaphycus alvarezii.
