The hydrogen supplied to the fuel cells is turned into electricity, which, in turn, is feeding directly the bus drive system which consists of an axle with electric motors. The bus is also fitted with a Solaris High Power battery acting as an additional electric power storage facility. The hydrogen is stored in five composite tanks of the latest generation placed on the bus roof. The sole by-products generated during the operation of the Solaris Urbino 12 hydrogen are heat and steam. Consequently, the vehicles do not release any noxious substances into the environment whatsoever. What is more, owing to the applied technology, Urbino 12 hydrogen buses are able to pull level with vehicles with conventional drives as regards their range.
