Since September 8th a total of 10 hydrogen-powered Toyotas have been prowling the inner city of Hamburg waiting for you to (digitally) hail them. But thanks to its slightly different operating system, CleverShuttle, unlike Uber Pop, hasn't been banned from many German cities. The taxis themselves are brand new Toyotas which run completely on a hydrogen fuel cell, the infrastructure for which is in its infancy. The introduction of hydrogen powered cars has only been made possible by the increase in hydrogen refuelling stations (or HRSs). The vehicles themselves have a reinforced fuel tank to compensate for the volatile nature of hydrogen and sensors ensure that, if a crash occurs, the flow of hydrogen is stopped so it doesn't escape the tank and ignite.
