The CO2 emissions situation is further improved when biomethane is used: when 20 per cent biomethane is added to the natural gas at the refilling station, this by itself reduces CO2 emissions by 39 per cent. When fuelled with pure biomethane, the cars emit up to 97 per cent less CO2.
Today, biomethane is blended at one-fourth of the available natural gas refilling stations in Germany; in addition, nearly 100 stations already offer pure biomethane. This number is the most of any country in the world.
Volkswagen has been equipping vehicles with natural gas drives since the beginning of the 1990s.Today the company offers six natural gas powered vehicles in various classes: the Caddy 2.0 EcoFuel, the extended Caddy Maxi 2.0 EcoFuel (each 80 kW / 109 PS), the Touran 1.4 TSI EcoFuel, the Passat and Passat Estate 1.4 TSI EcoFuel (each 110 kW / 150 PS) and the entirely new eco up! (50 kW / 68 PS). In the upcoming year, the new Golf will also debut in an EcoFuel version. In this vehicle, Volkswagen is offering one of the world’s most versatile natural gas vehicle programs.
With new car models like the eco up!, great progress in the area of producing CO2-neutral gas and extending the refilling station infrastructure as well as governmental support for this type of clean drive will make it possible to significantly expand the share of gas vehicles in large areas of Europe. In Germany, there are currently around 97,000 natural gas vehicles (as of mid-2012); in 2011, the inventory rose by 4.3 per cent.
