The heart of the Urbino 18 hydrogen bus is a cutting-edge fuel cell that acts as a miniature hydrogen power plant. Hydrogen is transformed by the fuel cell into electricity which is then transferred to the driveline. Solaris�s new vehicle doesn�t feature a conventional engine compartment as it has been equipped with a modular drive system. The space thus saved allowed the bus maker to increase the vehicle�s passenger capacity. Depending on the configuration, the bus will be able to carry up to 138 passengers. Thanks to the hydrogen technology applied and an increased number of new, light hydrogen tanks, the brand-new bus will perform excellently on longer routes. It will be able to cover about 350 km on a single refill in various weather conditions. Full refuelling of the vehicle takes around 20 minutes.
