The aim of the CUTE project was to develop and demonstrate an emission-free and low-noise transport system, including the accompanying energy infrastructure, which has great potential for reducing the global greenhouse effect towards the Kyoto protocol, improving the quality of the atmosphere and life in densely populated areas and conserving fossil resources. For the CUTE project a total of 27 buses were built by EvoBus. These vehicles are based on the Mercedes-Benz Citaro model city bus and run on hydrogen using fuel cells for power generation. One of the participating cities was Porto, where the local bus company (STCP – Sociedade de Transportes Colectivos do Porto) is operating three buses. The hydrogen infrastructure is supplied by BP. The hydrogen is produced centrally by electrolysis from grid electricity. In the project, 1ST is conducting the study of the environmental impact (based on a well to wheel approach) of the operation of the buses and the comparison with conventional technologies (Diesel, compressed natural gas and electricity). This will include measurements of the actual consumptions of the vehicles for the different routes, identification of the road profiles, driving behavior, load and ambient conditions.
