CNG is an acronym for “Compressed Natural Gas”. CNG is an alternative to fossil fuels and is made of compressed methane gas. It is a cleaner form of energy and inexpensive.
There is more detailed information here:
Although CNG is quite clean-burning (cleaner, in fact, than MANY biofuels), it actually IS a fossil fuel. Like any natural gas, it is extracted from a gas well. And when it is gone, it is gone. So it is really only an ‘alternative fuel’ in the sense that it is finding use in applications in which it was formerly not used (like as a motor vehicle fuel).
“Compressed natural gas (CNG) is an environmental alternative to fossil fuels, mainly consisting of compressed methane (CH4) gas.”
Actually, storminmatt, CNG is made of compressed methane and there has been debate on whether methane is technically considered a fossil fuel or not. I have yet to find a straight answer, every source tells me different.
So yes, you would be correct about CNG being a fossil fuel if methane were considered so also.
Compressed Natural Gas (CNG) is a noncorrosive, nontoxic alternative fuel used mostly in transportation vehicles since the 1940s. It is natural gas compressed to 1% of it’s volume, which burns 90% cleaner than regular gas. At about half the cost of gasoline, the use of CNG is becoming increasingly popular, with a home refueling unit introduced in 2005, called “Phill,” which hooks up to a natural gas line already used in the home. CNG capable vehicles have grown to over 6 million worldwide, and are especially popular in the state of California, where over 2200 buses use CNG in Los Angeles alone.
