A number of other cities around the world have either begun testing or rolling out buses that do not rely on burning fossil fuels. London and Gothenburg have seen electric buses introduced to their fleets, while hydrogen fuel cell buses were being trialled in Hamburg and north-east China as early as 2009.
The Toyota-Hino bus is powered by the Toyota Fuel Cell System developed for use in the Toyota Mirai.
