Climb Aboard For 90 Percent Less CO2

Sweden's Scania has produced a standard-sized low-floor city bus that cuts CO2 emissions by up to 90 percent when fuelled with ethanol and saves at least 25 percent fuel, compared with a bus running on conventional petrol or diesel.

Twelve of the hybrid-drive buses equipped to run purely on ethanol will start regular operation in Stockholm in 2008 and 2009 in cooperation with the city's public transport operator, SL (Storstockholms lokaltrafik). Ten of these are partly financed by the Swedish Energy Agency.

The new bus also meets some of the world's toughest emission levels - Euro 5 and EEV - and it uses technology which is designed to last the life of the vehicle. For example, energy storage is by way of supercapacitors, which are much more robust than batteries, especially in heavy-duty applications such as trucks and buses (where there is also room for the capacitors' bulk).Debuting at the UITP public transport congress in Helsinki 21-24 May 2007, the new Scania is the result of a three-year development project conducted at the Scania Technical Centre in Södertälje, Sweden.

Hasse Johansson, Group Vice President Research and Development at Scania, says of the development, "Making public transport more convenient to attract more passengers is the best way to combat congestion and reduce environmental problems in cities.

"The ethanol hybrid concept bus demonstrates Scania's commitment to participate in the transition into a sustainable urban transport system — a transition that needs to start right away.

"Scania sees no reason to wait for other new fuels and technologies that could become viable in 10 years' time.

"With our innovative hybrid-drive concept we improve fuel economy and cut emissions by at least 25 per cent and running on ethanol reduces CO2 emissions by up to 90 per cent. This combination of technologies paves the way for affordable and realistic city transport for many years to come."

Scania considers ethanol to be by far the most cost-efficient renewable fuel on the market today, taking into account factors such as availability, infrastructure and access to proven technology.
