The Clean urban Transport for Europe (CUTE) was a European project which saw the deployment and testing of 27 Citaro fuel cell buses – three buses in each of nine cities in Europe (Hamburg, London, Barcelona, Stockholm, Porto, Stuttgart, Amsterdam, Luxembourg, and Madrid).
The aim of the project was to demonstrate the feasibility of an innovative, highly energy-efficient, clean urban public transport system. Different hydrogen production and refueling infrastructures were established in each of the cities. The project saw practical applications of renewable energy sources to the transport system.
The project greatly improved public acceptance of the hydrogen fuel cell transport system, and contributed to the development of a more secure energy supply for the EU.
