Solaris: Bratislava goes for hydrogen

Slovak carrier Dopravný podnik Bratislava (DPB) has chosen Solaris to manufacture and supply four hydrogen buses

Slovak carrier Dopravný podnik Bratislava (DPB) has opted for four hydrogen buses produced and supplied by Solaris. This is the first order placed under a framework agreement. In the long term, up to 40 Urbino 12 hydrogen-powered vehicles could make their way to the Slovak capital.

This week, the public transport company in Bratislava signed a contract for the purchase of four Solaris Urbino 12 hydrogen buses. They will be the first hydrogen buses ever, not only in Bratislava, but also in Slovakia. Under a framework agreement that DPB has concluded with the bus maker, the Slovak transport company will eventually be allowed to order up to 40 hydrogen buses. The first four Urbino 12 hydrogen vehicles will be delivered in July next year.

“Our partnership with Bratislava started in 2006. Over the years, we have delivered 50 diesel and CNG powered vehicles to that city. We are currently guiding DPB in the deployment of hydrogen technology, one of the most crucial when it comes to planning modern and clean urban public transport. In this way, Bratislava sets a good example for other European cities,” says Javier Calleja, CEO of Solaris Bus & Coach.

The heart of the Urbino 12 hydrogen bus is a 70 kW fuel cell package that acts as a miniature hydrogen power plant on board the vehicle. The hydrogen system also has auxiliary equipment, for example to supply hydrogen and air at sufficient pressure, to recycle unused hydrogen and also to maintain a good and stable temperature of the fuel cells during operation. Electricity generated in the fuel cell while the vehicle is moving is passed directly to the powertrain. The hydrogen is stored in gaseous form in state-of-the-art composite tanks placed on the roof of the bus. The hydrogen tanks themselves have been rigorously tested and designed to ensure maximum safety for the driver, passengers and pedestrians.
