Compressed Natural Gas (CNG) as fuel

Compressed Natural Gas (CNG) has been used as a fuel for automobiles in a number of countries. CNG is less CO2 intensive than petrol and diesel and more importantly has much lower CO, NOx and particulates and due to this reason has been promoted in a number of Indian cities for powering public transport.  The environmental benefits of CNG are enhanced further if it is blended with H2 upto 18% and the blended fuel is designated as HCNG.
