Abstract:
Compressed Natural Gas (CNG) is becoming more and more important as a transport fuel. Already in 2007, seven million cars were fueled by CNG. The number of Natural Gas Vehicles (NGV’s) is increasing rapidly. CNG is a relatively clean transport fuel. The emissions of CO2, particles and sulfur are significantly lower than for other conventional fossil fuels. Fossil CNG can easily be replaced by CNG produced from biomass (Bio-CNG or Bio-Methane), because the composition of the gas and the heating value are similar. Replacing CNG by Bio-CNG will reduce fossil CO2 emissions to zero. Bio-CNG even has the potential to become a CO2 negative transport fuel, because part of the carbon from the biomass is separated as pure CO2 from the fuel during the production of Bio-CNG. If this pure CO2 stream is sequestrated, Bio-CNG becomes CO2 negative.
