Gallery: Mercedes Fuel Cell Buses Log 2 Million Emission-Free Kilometer...


Mercedes has been using a fleet of 36 hydrogen fuel cell buses in Hamburg, Germany, to improve fuel cell technology for its passenger cars. Now those test buses have logged an amazing 2 million emission-free kilometers! And even better than that, in the process of testing the buses, Mercedes has made improvements to the technology, allowing it to reduce the number of hydrogen tanks onboard from 9 to 7 while still improving performance and efficiency. In fact, these giant buses can now drive 155 miles on one fill-up of hydrogen, with a few miles of battery power left to get them home after they run out.

Compare that to the diesel-belching buses we’re familiar with in the U.S., and the implications for future cars becomes more apparent. These fuel cell buses are traveling with zero emissions, because they have replaced their diesel engines with clean hydrogen fuel cells. That means absolutely no emissions to scent your downtown with eau du diesel. No word yet on whether Mercedes plans to bring these buses to the U.S., but if they do come State-side you can expect to see them in the Bay area of California first.

    And a normal bus can get nearly 400 miles on a tank. And is a fraction of the cost. As for those diesel belching buses, filtration technology is capable of reducing overall smog levels. And you can convert or run a bus on natural gas or propane for less money. Besides according to transit data, the average city bus in America carries no more than 9 passengers average through out the day. Why use a forty passenger bus to carry roughly nine people when a small bus or paratransit vehicle works just as well and takes up less space and can probably maneuver better. Overall it makes no sense to have large transit systems anymore (rail or large buses) especially when we can have small box transit (buses, shuttles, jitneys and vans) that takes groups of people where they want/need to go specifically then home again and simply shut down when rush hour ends while using a small fleet of road vehicles to pickup the strays during odd hours of the day. Wait until it’s needed then go out and do it again. And you can save more energy and reduce pollution overall by not having large mostly empty vehicles going out through most of the day, and that’ll save more than a fleet of really expensive fuel cell buses that may only pick up scant amount of passengers while running it’s route all day. That’s why you don’t want high occupancy transit, you want low occupancy transit that offers direct point to point transportation. They have entire private transit firms that operate in cities like Houston, Vegas, Atlantic City using similar vehicles where they compete with the subsidized public transit which uses large 40-60 passenger buses or larger articulated buses that cost as much as half a million dollars. These buses may have logged 2 million kilometers, Meanwhile intercity buses in America have been logging billions of passenger miles a year and since they are typically filled with passengers, they are more efficient than these fuel cell buses and less expensive.

    The public buses in my area are diesel/over-head electric, which makes things a bit cleaner than just diesel. But, these hydrogen buses could help reduce the complexity of that configuration. Those over-head wires cannot be easy to maintain, given southwest Ohio’s propensity for ice storms in January and February.
