USPC 2009 PRELIMS
The concept of carbon credit originated from which one of the following?
A Earth Summit, Rio de Janeiro
B Kyoto Protocol
C Montreal Protocol
D G-8 Summit, Heiligendamm
NOTES
In a first, Delhi is all set to roll out hydrogenenriched 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
NOTES
In order to help study the technology as well as its infrastructure requirements, 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
Under this project, the IOCL plans to test the performance of buses as well as the reduction in emissions by mixing 18 to 20 per cent of hydrogen to compressed natural gas (CNG) in every bus. Delhi’s air pollution has been a problem for a while now
H- CNG – NO MODIFICATION REQUIRED
- The best thing about HCNG is that it does not require any modification of the engine or retrofitment.
- Only some calibration is required in the bus. Whatever work is needed will be done at the depot. HCNG will reduce carbon emission by up to 20% in each of the 50 CNG bus
- Hydrogen is extracted from methane and is blended with CNG to create HCNG whose carbon emission is far lesser than CNG.
FINANCE
According to the company’s preliminary assessment, the cost escalation for shifting to HCNG buses will be about 72 paise per kilometre, and it hopes, once the technology is used on a large scale, it would break-even
