CNG, also known as compressed natural gas, is an eco-friendly alternative to gasoline. This natural gas is the same gas that you use daily to heat your home and water, cook on the stove and even to dry your clothes in a dryer. The use of CNG fuel is becoming more popular with both commercial and non-commercial vehicles. The natural gas arrives at the station at a low pressure from a local gas utility line.
An underground compressor then takes that fuel and compresses it to a higher pressure. After the compression of the natural gas, the CNG is then transferred to storage vessels so that the fuel is readily available. CNG is one of the cleanest burning fuels available. The use of CNG reduces carbon monoxide emissions 90 to 97 percent. In fact, in terms of pollution reduction, converting one truck from diesel to natural gas is the equivalent of taking as many as cars off the road. Natural gas is at the forefront of the growing conversation surrounding sustainability and clean energy.
Corporations, municipalities and some consumer car manufacturers are utilizing compressed natural gas CNG as an alternative fuel source to diesel or propane.
Compressed natural gas, in its most basic form, comes from the ground. According to the U. Department of Energy , natural gas is found near oil wells during extraction.
Because RNG is chemically identical to fossil-derived conventional natural gas , it can use the existing natural gas distribution system and must be compressed or liquefied for use in vehicles. Both are domestically produced, relatively low priced, and commercially available. To provide adequate driving range, CNG is stored onboard a vehicle in a compressed gaseous state at a pressure of up to 3, pounds per square inch.
CNG is used in light-, medium-, and heavy-duty applications. One GGE equals about 5. Rising Sea Level. Compressed natural gas Figure 1. Compressed natural gas in a vehicle.
