Compressed natural gas vehicles require a greater amount of space for fuel storage than conventional petrol-powered vehicles. Since it is a compressed gas, rather than a liquid like petrol, CNG takes up more space for each GGE (petrol gallon equivalent). However, the cylinders used to store the CNG take up space in the trunk of a car or bed of ...
A natural gas vehicle (NGV) utilizes compressed natural gas (CNG) or liquefied natural gas (LNG) as an alternative fuel source. Distinguished from autogas vehicles fueled by liquefied petroleum gas (LPG), NGVs rely on methane combustion, resulting in cleaner emissions due to the removal of contaminants from the natural gas source.
As of 2019, there were more than 1.49 billion motor vehicles on the world's roads, [4] compared with approximately 159 million alternative fuel and advanced technology vehicles that had been sold or converted worldwide at the end of 2022 and consisting of:
One GGE of natural gas is 126.67 cubic feet (3.587 m 3) at standard conditions. This volume of natural gas has the same energy content as one US gallon of gasoline (based on lower heating values: 900 BTU/cu ft (9.3 kWh/m 3) of natural gas and 114,000 BTU/US gal (8.8 kWh/L) for gasoline). [22]
In 1994 the U.S. National Institute of Standards and Technology (NIST) introduced gasoline gallon equivalent (GGE) as a metric for fuel economy for natural gas vehicles. NIST defined a gasoline gallon equivalent (GGE) as 5.660 pounds of natural gas, and gasoline liter equivalent (GLE) as 0.678 kilograms of natural gas. [18]
The Honda Civic GX first appeared in 1998 as a factory-modified Civic LX that had been designed to run exclusively on CNG (compressed natural gas). In 1998 the Civic GX cost $4500 more than a comparable Civic LX. [10] The car looked and drove just like a contemporary Honda Civic LX, but did not run on gasoline.
Unlike hydrogen vehicles, CNG vehicle technology has been available for many decades, and there is sufficient infrastructure in existing filling stations to provide both commercial and home refueling. Worldwide, there were 14.8 million natural gas vehicles by the end of 2011, mostly in the form of bi-fuel vehicles. [175]
