What is CNG

Compressed Natural Gas

Compressed Natural Gas (CNG) is compressed form of natural gas stored and distributed at a normal pressure of 200–220 bar (2900–3200 psi). It is a cost effective and environmental friendly substitute for conventional fuels like petrol, diesel, propane etc. It is much safer than other fuels as in the event of a spill / leakage, natural gas being lighter than air, ascends quickly.

The key Drivers of CNG are:

  • Economics: On an energy-equivalent basis, natural gas is comparatively less costly vis-a-vis conventional fuels like LPG, gasoline and diesel. Natural gas is a clean-burning fuel that reduces vehicle maintenance such as extended interval of oil change and long life of standard spark plugs.
  • Eco Friendly:Emission levels from CNG vehicles are significantly lower than conventional fossil fuels like Petrol and Diesel and meet BS-VI standards. Lower level of GHG emissions will help in achieving India’s Nationally Determined Contribution pledged in Paris Agreement (UN Climate Change Conference 2015 - COP 21). Natural Gas (CNG/LNG) fuelet vehicles ... meet all safety requirements vis-à-vis traditional fuels such as petrol and diesel. Furthermore, these vehicles are safer as CNG ascends quickly in the air during an accident. Additionally, CNG fuel systems are “sealed,” which prevent any spill or evaporative losses. 1.6. Natural gas is non-toxic and non-corrosive. It does not contaminate ground water.

Benefits of using CNG

  • Green Fuel:
    Commonly referred to as the green fuel because of its lead and sulphur free character, CNG reduces harmful emissions. Being non-corrosive, it enhances the longevity of spark plugs. Due to the absence of any lead or benzene content in CNG, the lead fouling of spark plugs and lead or benzene pollution are eliminated.
  • Safe Fuel:
    The properties of CNG make it a safe fuel. It is stored in high gauge seamless cylinders which are certified so negligible chance of leakage. It is lighter than air, so in case of leak it just rises up and disperses into the atmosphere and mixes in the air easily and evenly.
  • High auto ignition temperature:
    CNG is less likely to auto-ignite on hot surfaces, since it has a high auto-ignition temperature (540 degrees centigrade) and a narrow range (5%-15%) of in flammability. It means that if CNG concentration in the air is below 5% or above 15%, it will not burn. This high ignition temperature and limited flammability range makes accidental ignition or combustion very unlikely
  • Dual facility:
    CNG Vehicle can run both on CNG and Petrol.
  • Increased life of oils:
    Another practical advantage observed is the increased life of lubricating oils, as CNG does not contaminate and dilute the crankcase oil.

Physical properties of natural gas

  • Natural gas is colourless and odourless.
  • Natural gas is primarily methane, with small amounts of other hydrocarbons.
  • Natural gas is non-toxic.
  • Natural gas is lighter than air; if it escapes, it will rise and dissipate.
  • Natural gas is clean-burning; when burned with the proper amount of air, it produces heat, carbon dioxide and water vapor.

Our Aim

  • Mass Tree Plantation Drive: Greenmosphere aims at mass tree plantation drive to increase the fresh source of oxygen.
  • Reducing Greenhouse Gases: We aim at reducing the copious amount of greenhouse gases and helping in achieving the goals of the Sustainable Development Goals (SDG) by halting deforestation, boosting afforestation and supporting wetland conservation.
  • Spreading Awareness: Green Millennials aim at creating a platform to spread awareness amongst the educational institutions.
