The Slovak company Rošero in cooperation with the Faculty of Mechanical Engineering of the Technical University in Košice has built a prototype hydrogen bus.

The hydrogen bus uses low-pressure metal hydride storage tanks for hydrogen storage as the main source of energy for the bus propulsion. This is a progressive technology with a strong emphasis on safety. The bus has a power output of 100 kW and can travel a distance of up to 200 km on a single refuelling. It is also expected to enter series production in the future.
