Hyundai Motor Group’s hydrogen-powered fuel cell bus Elecity FCEV provides public transport in Vienna in this picture released Sunday. 

Austria’s public transportation corporation Wiener Linien began running the eco-friendly bus on its most crowded bus route, according to Hyundai. 

The Korean carmaker’s supply of Elecity FCEV is part of the Austrian government-led hydrogen infrastructure expansion project called HyBus Project.

Starting with the delivery of three Elecity FCEV to the Austrian capital city, additional buses will run in other cities -- Graz and Salzburg -- according to the company. Elecity FCEV has been chosen as the partner of Austria’s HyBus Project for its capacity to run up to 550 kilometers per single charge.
