The hydrogen-powered CityCat H2 that is being trialed on the streets of Basel, Switzerland
For the past couple of years, a street cleaning vehicle has been washing, brushing and vacuuming the streets of Basel in northwest Switzerland. While there's nothing unusual about that, what is noteworthy is that the vehicle, known as the CityCat H2, is powered completely by hydrogen. The street sweeper is part of a project to practically test the feasibility of hydrogen-powered vehicles under real-world conditions and the results from the trial indicate that, although hydrogen-powered vehicles can save energy, are environmentally friendly, and technically feasible, the prices of fuel cells, pressurized storage tanks and electric drives must all drop significantly before such vehicles are cost-effective.
