In a major step toward adopting alternative clean fuel for transportation, the Ministry of Road Transport and Highways has allowed use of H-CNG (18% mix of hydrogen) in CNG engines.
The Ministry has been notifying various alternate fuels under Clean Fuels for transportation.
The Bureau of Indian Standards (BIS) has also developed specifications (IS 17314:2019) of Hydrogen enriched Compressed Natural Gas (H-CNG) for automotive purposes, as a fuel.
HCNG or H2CNG (hydrogen compressed natural gas) is a mixture of compressed natural gas and 4–9 percent hydrogen by energy. It may be used as a fuel gas for internal combustion engines and home appliances.
Certain CNG-engine were tested to understand the emission reduction using H-CNG as compared to ‘neat’ CNG.
A notification for amendments to the Central Motor Vehicles Rules 1989, for inclusion of H-CNG as an automotive fuel has been published.
