Hyundai Motor Co. debuts next-gen fuel cell buses
Eco Factor: Zero-emission hydrogen fuel cell buses.
Three years after introducing its first fuel cell bus, Hyundai Motor Co. has recently launched the next-gen fuel-cell buses, which with added technology and engine refinement are much better than their old buses. The company claims that with a better engine, the buses plying on fixed routes need at most two fueling stations, one at each terminus, which is easy to build and is cost-effective as well.
Based on the latest Low Floor Aero City bus platform, the newest fuel cell electric bus features numerous technical refinements which have increased the maximum speed to 100km/h. This improves on the 75km/h limit of the previous system which relied on a single 240kW motor. Under the new architecture, three 100kW Permanent Magnet Synchronous Motors are arranged in parallel to provide a total of 300kW of propulsion for a 33 percent improvement in top speed.
This new generation of ecofriendly buses will be put into daily service in cities around Korea. The company estimates that powered by six cylinders of hydrogen mounted on the rooftop, the buses will have an operating range of over 350km, while driving in city mode.
The Dark Side:
Currently the buses will only be available in Korea and considering the cost of hydrogen storage and fuel cells, hydrogen-power doesn’t seem to be the need of the hour.
