Fundació Gas Natural has published a study on how CNG vehicles can improve the air quality in Barcelona and Madrid, Spain. Of course, Gas Natural sells natural gas and is quite interested in this happening, but the study was performed with the Mare Nostrum supercomputer in the Universitat Politècnica de Catalunya's Campus Nord in Barcelona. It's claimed that this is the 9th most powerful computer in the world, and the most powerful in Europe.
According to their results, Barcelona could improve its air quality if 50 percent of its delivery vans used CNG (compressed natural gas) instead of diesel. Barcelona is considered one of Europe's most polluted cities because of its configuration, surrounded by hills and is currently taking (yet to be effective) measures to cut down on pollution. In the case of Madrid, and because of different traffic patterns (more highways and more extension), a similar target would be achieved if 10 percent of private cars ran on CNG.
At the same time, Madrid's city hall, Repsol-YPF, SEAT, the Federación Profesional del Taxi and the Asociación Gremial de Auto Taxi (the two taxi-drivers' unions) have signed an agreement to promote the use of LPG (Liquified Petroleum Gas) in taxis, in order to replace as many diesel cars as possible. Taxis are considered a key segment to reduce pollution because one percent of cars in the city are taxis, and they are responsible of 20 percent of the trips in the city. SEAT sold discounted 1.6 gasoline Toledo models (pictured above) which were transformed to LPG use by Repsol-YPF for free. Buyers even got a 1,100 EUR LPG card.
