State-owned public transport company BVG (Berliner Verkehrsbetriebe) has announced its intention of buying 250 hydrogen-powered buses for Berlin. Two of the new buses were succesfully put to the test during the recent FIFA World Cup football championships, transporting thousands of fans from Tegel International Airport to the Olympic Stadium. The emission-free buses cost around 361,000 each, four times the price of their diesel-powered equivalent. They will be paid for with subsidies from the European Union and should be delivered by 2009, making Berlin the first European city with a significant proportion of environmentally-friendly buses.
