Hydrogen Enriched Compressed Natural Gas CNG (HCNG)
HCNG is an important topic for Mains General Studies Paper 3 under the topic Conservation, environmental pollution, and degradation, environmental impact assessment.
UPSC 2009 PRELIMS-QUESTION
The concept of carbon credit originated from which one of the following?
1.Earth Summit, Rio de Janeiro
2.Kyoto Protocol
3.Montreal Protocol
4.G-8 Summit, Heiligendamm
ANSWER – 2.Kyoto Protocol
NOTES
In a first, Delhi is all set to roll out Hydrogen-Enriched CNG (HCNG) buses for public transport next year onwards.
Interestingly, by doing so, the National Capital will become the first city in India to launch HCNG buses.
CNG was launched in 1991 to reduce pollution.
The government of Delhi has tied up with Indian Oil Corporation Limited (IOCL), which is a Public Sector undertaking, to induct 50 HCNG-fuelled buses.
THE MIX
Here, the Hydrogen is extracted from Methane an is blended with CNG to create HCNG whose Carbon emission is far lesser than CNG.
20% -18% of Hydrogen will be mixed with a compressed natural gas(CNG), 80% will be CNG.
Eastern Peripheral Expressway
Step by the Central Government
The Delhi-NCR region just got a brand new expressway – the Eastern Peripheral Expressway, that extends from Kundli, just north of the National Capital, to Palwal to the south of the city.
The expressway was built to ease congestion and pollution in the national capital by diverting trucks along this route. It’s also a good road to take if you want to bypass Delhi if you are heading to Agra, Mathura or even Faridabad.
Entry of 50 thousand fewer trucks controls the pollution of Capital.
H-CNG-NO MODIFICATION REQUIRED
It does not need any modification in the engine.
In each of the 50 CNG bus, the HCNG will reduce carbon emission by up to 20 percent.
Completely hydrogen based motors(COMING TIME)
0 emission of carbon.
Only produces water and heat.
Mileage will increase from 4 to 5 %
FINANCE
According to the company’s preliminary assessment, the cost escalation for shifting to HCNG buses will be 72 paise per kilometer, and it hopes, once the technology is used on a large scale, it would break -even.
