Natural gas and CNG
CNG is an international abbreviation for Compressed Natural Gas, an ecological fuel. Gas is available from the Worldwide, European and Czech gas supply systems and used for production of heat and electricity. To be used as fuel for combustion engines it must be compressed about 200 x using high-pressure compressors.
In passenger and commercial vehicles it is used only in petrol engines, in trucks and buses it can also be used in diesel engines. In addition to compressed natural gas, treated biogas can be used (which is made of biomass is a renewable resource).
List of CNG vehicles
CNG drive is built in from production for example in the following vehicles: Fiat Punto Evo, VW Passat TSI EcoFuel, Opel Zafira 1.6 CNG ecoFLEX Turbo, Ford C-Max CNG. Premium CNG-powered vehicles include Mercedes B 180 NGT and Mercedes E 200 NGT. CNG can also be used in many other models of Fiat, VW, Opel, Ford, Mercedes or Honda.
Worldwide use of CNG
Use of compressed natural gas worldwide is in a widely developed stage. By the end of 2011 a total of 14.5 million CNG vehicles were used worldwide, of that 1.5 million in Europe and 3,500 vehicles in the Czech Republic, including about 300 buses. Due to its low price and widespread availability, CNG is more widespread in the developed countries of Asia and South America.
Filling technology and filling stations
To secure the maximum vehicle range, gas must be compressed (power concentration). This compression is provided by filling stations/compressors. As of 1 September 2012 there were 41 public filling stations in the Czech Republic and many private filling facilities. This number increases by approximately 20 % every year.
