To Curb Pollution Delhi Turns to Hydrogen Power for Future Buses

We have been talking about the rising pollution levels in Delhi and how it’s getting hazardous for a while now. To curb pollution, the Delhi government is planning to push HCNG fuel on DTC buses which is a blend of hydrogen and CNG (compressed natural gas).

Though the earlier plan was to procure electric buses, it seems that plan has taken a detour and now the government is ready to push a pilot that will involve 50 buses running on HCNG fuel.

This move has come into effect after the Supreme Court has directed the Delhi government to introduce zero-emission and cost-effective buses for Delhi roads. But, is Hydrogen power fuel really effective and what happens to the buses already running on Delhi roads?

  • 1. What is HCNG?

    Hydrogen as a resource is considered to be the most promising fuel for the automotive sector. Being number one on the periodic table, it is one of the most combustible as well. Not something to be played around with.

    It’s the same fuel that’s used to power space rockets and is very powerful. The only reason that the government has considered to use this fuel, blended with natural gas, is because it has very few emissions and increases the performance of the automobile.

    HCNG is a mix of hydrogen and CNG. This fuel contains 18 percent of hydrogen while the rest of it is compressed natural gas. The Hydrogen is extracted from methane and is blended with CNG to create a gas, which has far fewer carbon emissions than CNG.
