Delhi will be first city to launch HCNG buses next year

Delhi will be the first city in India to roll out hydrogen-enriched CNG (HCNG) buses for public transport next year onwards.

The Delhi government has tied up with Indian Oil Corporation Limited (IOCL), a public sector undertaking, to induct 50 HCNG-fuelled buses on a trial basis to help study the technology and its infrastructure requirements.

IOCL plans to test the performance of buses and reduction in emissions by mixing 18-20% of hydrogen to CNG (compressed natural gas) in every bus. “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,” said transport commissioner Varsha Joshi.


The IOCL, on Wednesday, conveyed to the Delhi government that it would use the Rajghat depot for the trials, work for which is set to begin by the end of this month.“Until now, we have been doing trials with two buses in Faridabad. Soon, we will begin HCNG trials on 50 CNG buses of the Delhi government. Our assessment says that HCNG buses also give 3-4% fuel economy improvement compared to a CNG bus. While they reduce carbon footprint, there is no reduction in nitrogen oxide emissions,” Kumar said.

Preliminary assessment by the company has revealed that the cost escalation for shifting to HCNG buses will be about 72 paise per kilometre, which it hopes would break-even once the technology is used on a large scale.

On July 2, the Supreme Court had asked the Delhi government to explore the feasibility of introducing ‘zero emission’ and cost effective hydrogen-run public transport buses instead of procuring electric buses for the city.
