      Notes:<\/h3>\n\n\n\n
        \n
      • CNG is compressed natural gas. <\/strong>With natural gas mainly composed of methane, CNG emits less air pollutants<\/strong> (carbon dioxide, carbon monoxide, nitrogen oxides and particulate matter) than petrol or diesel.<\/li>\n\n\n\n
      • H-CNG<\/strong> is a blend of hydrogen and CNG<\/strong>, the ideal hydrogen concentration being 18%.<\/li>\n\n\n\n
      • Compared<\/strong> to conventional CNG, use of H-CNG can reduce emission of carbon monoxide up to 70%<\/strong>, besides enabling up to 5% savings in fuel<\/strong>, tests by the Automotive Research Association of India <\/strong>and Indian Oil Corporation Ltd (IOCL) have found.<\/strong><\/li>\n\n\n\n
      • H-CNG which may be used as a fuel of Internal Combustion Engine (ICE) is considered a cleaner source of fuel, more powerful and offers more mileage<\/strong> then even CNG.<\/li>\n\n\n\n
      • The Environment Pollution Prevention and Control Authority (EPCA)<\/strong> recently recommended to the Supreme Court that Delhi\u2019s buses switch to H-CNG within the next two or three years.<\/li>\n\n\n\n
      • The Ministry of Petroleum & Natural Gas<\/strong> had also issued a draft notification, following a NITI Aayog proposal<\/strong>, for H-CNG as an automotive fuel.<\/li>\n\n\n\n
      • However, it\u2019s an inexpensive switch<\/strong> as in its report to the Supreme Court, the EPCA has estimated that to fuel Delhi\u2019s 5,500 buses, about 400 tonnes H-CNG would be needed per day. Setting up four fuel-dispensing facilities would cost Rs 330 crore, which can be funded from the Environment Compensation Charge (ECC) fund made up of cess on commercial vehicles entering Delhi, it said. For consumers who pay Rs 42 per kg for CNG<\/strong>, the cost of H-CNG would not be more than Rs 43 per kg.<\/strong><\/li>\n\n\n\n
      • H-CNG has not yet gained worldwide <\/strong>currency. Trials<\/strong> have been held in countries such as the US, Canada, Brazil and South Korea<\/strong>.<\/li>\n<\/ul>\n\n\n
