The government is going ahead with a massive push for clean fuel, coupled with an expansion of city gas distribution (CGD). The ninth and tenth rounds of CGD bidding are expected to see investments of around Rs 1.2 trillion in a decade, of which a major chunk of the business is dependent on compressed natural gas. CNG may turn out to be the key to India’s automobile future and the dream of increasing the share of natural gas to 15 per cent in its energy basket, from around 6 per cent now.
