In the context of proposals to the use of hydrogen-enriched CNG (H-CNG) as fuel for buses in public transport, consider the following statements:
1. The main adyantage of the use of H-CNG is the elimination of carbon monoxide emissions.
2. H-CNG as fuel reduces carbon dioxide and hydrocarbon emissions.
3. Hydrogen up to one-fifth by volume can be blended with CNG as fuel for buses.
4. H-CNG makes the fuel less expensive than CNG.

Statement 1 is incorrect: H-CNG reduces the emission of Carbon Monoxide up to 70%. Statement 2 is correct: H-CNG as a fuel reduces the emission of carbon-di-oxide and hydrocarbon as compared to other fuels. Statement 3 is correct: CNG as a fuel can be used in place of gasoline, diesel fuel and propane (C3H8) / LPG and its combustion produces fewer undesirable gases then the other mentioned fuels. Statement 4 is incorrect: Current cost of H2 is more than the cost of Natural Gas. Therefore, HCNG’s cost is more than CNG.
