Our driving force behind the development of gas technology has always been the attractive environmental balance of Natural Gas and Biomethane: Up to 99% lower particulate matter and up to 95% lower CO2 emissions when using bio-methane are real arguments.
This is why Liquefied Petroleum Gas (LPG), which is widely used in the passenger car sector, does not play a role in our gas vehicles: LPG is a waste product from oil production and refineries and leads to significantly higher CO2 emissions than our favoured fuels – natural gas and Bio-Methane.
Natural gas, also known as methane, is a fossil fuel such as petrol and diesel, but burns in a much more environmentally friendly way. The exhaust primarily emits steam – sulphur dioxides and soot particles are hardly emitted. The emissions of CO2, nitrogen oxides and carbon monoxide are significantly lower than those of diesel vehicles. Natural gas is non-toxic and odourless. With bio-methane increasingly being added to natural gas, the environmental impact is constantly improving.
Biogas, also bio-methane, corresponds in its chemical composition to natural gas, but is not of fossil origin. Biogas is obtained from plants and, during combustion, only the CO2 that the plants absorbed during their growth is returned to the atmosphere – this reduces the CO2 footprint by up to 95% compared to diesel vehicles. Fewer and fewer plants are being cultivated specifically for biogas production, because the gas can also be obtained from plant waste that has to be disposed of anyway.
