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 bar), usually in cylindrical or spherical shapes.
HCNG or H2CNG (hydrogen compressed natural gas) is a mixture of compressed natural gas and 4–9 percent hydrogen by energy. [1] It may be used as a fuel gas for internal combustion engines [2] [3] [4] and home appliances. (regarding the acronyms in the above emissions chart: AVL = Average Levels? CNG = Compressed Natural Gas HCNG = Hydrogen ...
Because natural gas emits less smog-forming pollutants than other fossil fuels when combusted, cleaner air has been measured in urban localities switching to natural gas vehicles. [65] Tailpipe CO 2 can be reduced by 15–25% compared to gasoline, diesel. [66] The greatest reductions occur in medium and heavy duty, light duty and refuse truck ...
In 2022, the U.S. Energy Information Administration released data that found 24% of Washington homes used natural gas cooking appliances. This includes stove tops and ovens. This includes stove ...

Many stoves use natural gas to provide heat. A gas stove is a stove that is fuelled by flammable gas such as natural gas, propane, butane, liquefied petroleum gas or syngas. Before the advent of gas, cooking stoves relied on solid fuels, such as coal or wood. The first gas stoves were developed in the 1820s and a gas stove factory was ...
Renewable natural gas can also be converted into liquefied natural gas (LNG) or compressed natural gas (CNG) for direct use as fuel in transport sector. In the United States, projections of the ultimate supply potential for RNG vary. An analysis conducted in 2011 by the Gas Technology Institute determined that renewable gas from waste biomass ...
If compressed, it can replace compressed natural gas for use in vehicles, where it can fuel an internal combustion engine or fuel cells and is a much more effective displacer of carbon dioxide than the normal use in on-site CHP plants. [30] [31] [32]
