Compressed natural gas ( CNG) is a fuel gas mainly composed of methane (CH 4 ), compressed to less than 1% of the volume it occupies at standard atmospheric pressure. It is stored and distributed in hard containers at a pressure of 20–25 megapascals (2,900–3,600 psi; 200–250 atm), usually in cylindrical or spherical shapes.
As of December 2011, Germany has 900 CNG filling stations in service. Gibgas, an independent consumer group, estimates that 21% of all CNG filling stations in the country offer a natural gas/biomethane mix to varying ratios, and 38 stations offer pure biomethane. [63]
Filling station. A filling station (also known as a gas station [ US] or petrol station [ UK ]) is a facility that sells fuel and engine lubricants for motor vehicles. The most common fuels sold in the 2010s were gasoline (or petrol) and diesel fuel . Fuel dispensers are used to pump gasoline, diesel, compressed natural gas, compressed hydrogen ...
Cascade filling system. A cascade filling system is a high-pressure gas cylinder storage system that is used for the refilling of smaller compressed gas cylinders. [ 1][ 2] In some applications, each of the large cylinders is filled by a compressor, otherwise they may be filled remotely and replaced when the pressure is too low for effective ...
The Metropolitan Utilities District, or M.U.D., is the political subdivision and public corporation of the U.S. State of Nebraska that operates the drinking water and natural gas systems for Omaha, Nebraska and surrounding areas. M.U.D. is the only metropolitan utilities district in the State of Nebraska, and the fifth largest public natural ...
Trust Chesapeake Energy (NYS: CHK) to play a heralding role for natural gas as the foremost alternative fuel to power vehicles in the future. Last week, Another Big Reason for Natural Gas to Pick Up
A Shell Autogas refuelling station. Autogas or LPG is liquefied petroleum gas (LPG) used as a fuel in internal combustion engines in vehicles as well as in stationary applications such as generators. It is a mixture of propane and butane . Autogas is widely used as a "green" fuel, as its use reduces CO 2 exhaust emissions by around 15% compared ...
Gasoline gallon equivalent ( GGE) or gasoline-equivalent gallon ( GEG) is the amount of an alternative fuel it takes to equal the energy content of one liquid gallon of gasoline. GGE allows consumers to compare the energy content of competing fuels against a commonly known fuel, namely gasoline. It is difficult to compare the cost of gasoline ...
