Q. Which of the following statements about Hydrogen CNG (HCNG) is incorrect?
Explanation:
Statement a is correct: The optimal ratio of hydrogen to CNG is difficult to achieve for uniformity. The variation of the mixing ratio results in different engine performances, fuel consumption, and emission characteristics. Therefore, the engine performance using HCNG as fuel can be optimized if the mixing ratio between the two fuels in HCNG can be adjusted in real-time while the engine is being operated.
Statement b is correct: HCNG is the ideal fuel for high load applications and heavy-duty vehicles.
Statement c is correct: Hydrogen blended CNG has emerged as an excellent alternative for achieving emission targets and import substitution. The existing IC engine without any significant modification can be run on H-CNG and with the minimal infrastructural upgrade, the existing CNG dispensing refueling infrastructure can be used to deliver H-CNG blends as well.
Statement d is incorrect: Through this pilot project, Delhi became the first city in the country to roll out hydrogen-enriched compressed natural gas (HCNG) buses for public transport with the launch of a six-month trial run of 50 BS-IV compliant cluster scheme buses (not 50 HCNG plants). As a pilot project, 50 buses have been filled with HCNG and their efficiency and emissions are recorded.
