  • Compressed Natural Gas (CNG) is a substitute for gasoline (petrol) or diesel fuel. It is considered to be an environmentally "clean" alternative to those fuels. It is made by compressing natural gas (which is mainly composed by methane (CH4), in a percantage range of 70% to 98%). It is stored and distributed in hard containers, at a normal pressure of 200/220bars, usually in cylindric of spherical shapes to maintain equal pressure on the walls of the containers.
  • CNG is basically produced by pressing natural gas at 3,000 psi pressure. Compressed Natural Gas (CNG) is usually produced on the fueling station site with a compressor based system. Natural gas is transported through pipelines to refueling stations and there compressed at a pressure of 3,000 psi with the help of specially installed compressors that enables it to be loaded as gas cylinders for vehicles. 
  • CNG cylinders can be made of steel, aluminium, or plastic. Lightweight composite (fibre-wrapped plastic) cylinders are especially beneficial for vehicular use because they offer significant weight reductions when compared with earlier generation steel and aluminium cylinders, which leads to lower fuel consumption.
  • The cylinder is used to store CNG at a working pressure of 200 bar. It is fitted with a shut-off valve and a safety burst disc. The cylinders are type approved by the Chief Controller of Explosives, Government of India.
  • CNG is basically produced by pressing natural gas at 3,000 psi pressure. Compressed Natural Gas (CNG) is usually produced on the fueling station site with a compressor based system. Natural gas is transported through pipelines to refueling stations and there compressed at a pressure of 3,000 psi with the help of specially installed compressors that enables it to be loaded as gas cylinders for vehicles.
  • The CNG market is more stable than the gasoline market. CNG generally costs 15 to 40 percent less than gasoline or diesel. CNG requires more frequent refueling, however, because it contains only about a quarter of the energy by volume of gasoline. In addition, CNG vehicles cost between $3,500 to $6,000 more than their gasoline-powered counterparts. This is primarily due to the higher cost of the fuel cylinders. As the popularity and production of CNG vehicles increases, vehicle costs are expected to decrease.
  • Everest Kanto Cylinder is the only other listed player in the business of manufacturing cylinders, having a market share of more than 80%.
  • CNG has grown into one of the major fuel sources used in car engines in Pakistan, Bangladesh and India. The use of CNG is mandated for the public transport system of New Delhi, India's capital city as well as mega city Ahmadabad in the state of Gujarat. The Delhi Transport Corporation operates the world's largest fleet of CNG buses. The government of Punjab, Pakistan, the most populous province of that country, has mandated that all public-transport vehicles will use CNG by 2007. 
  • Natural gas can be used to fuel almost any kind of vehicle - motorcycles and three wheelers, cars, vans & pickups, lift trucks, buses, trucks, trains, boats, even aircraft.
  • The demand for CNG vehicles is expected to grow given the firm oil prices, lower running cost and rising environmental concerns. The Supreme Court's decision mandating the use of CNG as auto fuel for heavy vehicles in New Delhi has created a demand for such cylinders by both OEMs (original equipment manufacturers) and retrofitters (conversion agents). 
  • Globally, an estimated 6 million vehicles run on natural gas which is expected to grow to 50 million by 2020. The major export markets are Argentina, Brazil Pakistan, Iran and China. India could account for around 15% of the global natural gas market. Demand for CNG cylinders has been growing at over 40% for the last three years. There is a huge mismatch in the demand-supply of CNG cylinders, which augurs well for the existing players.
  • Demand for CNG cylinders will be driven by the conversion of existing petrol & diesel vehicles to CNG cylinders. The other demand will be from the new vehicles in select cities such as Delhi, Mumbai and other 11 cities which are making it mandatory for vehicles to switch over to CNG from diesel / petrol that they may be using presently
