15 More Fuel Cell Electric Buses For UK Roads

The title of this post, is the same as that of this article on H2 View.

This is the introductory paragraph.

A further 15 fuel cell electric buses (FCEBs) are planned for the UK this year, as the country works towards its goal of deploying 4,000 zero emission buses over the next five years.

These futher points are made.

The fuel cells are 85KW heavy-duty FCveloCity®-HD fuel cell modules from Ballard Power Systems.

This will take Wrightbus’s order book for hydrogen-powered buses to fifty. all of which will be delivered this year.

Twenty buses are for London and fifteen are for Aberdeen.

I have some thoughts on the 85KW heavy-duty FCveloCity®-HD Fuel Cell Module.

This pdf file on the Ballard web site is the data sheet and this is selected data.

  • The net power is 85 kW
  • The fuel cell weighs 256 Kg.
  • It needs a coolant sub-system that weighs 44 Kg.
  • It needs an air sub-system that weighs 61 Kg.
  • It is a true zero-emission product.

It is worth looking at the power train of a New Routemaster bus, which although very different will probably give clues as to the weight that can be carried and the power and battery size needed for a full-size bus.

  • The Cummins ISBe diesel engine develops 138 kW and weighs 499 Kg.
  • The engine is mounted half-up the back stairs.
  • The Microvast Lithium Titanate battery has a capacity of 18 kWh.
  • The battery is placed under the front stairs.
  • The braking on the New Routemaster bus is regenerative.

These are some of my observations.

  • If you sit at the back of a New Routemaster bus, you can hear the engine, when it is running. On most routes in Central London, it certainly isn’t running all the time.
  • The battery doesn’t seem very large at 18 kWh.
  • The fuel cell with its sub-systems would appear to be lighter than the diesel engine, but of less power.
  • The fuel-cell won’t need the generator of the diesel bus.

I very much feel getting all the components into a standard double-decker bus will be a tight squeeze, but none of the individual components are that large or heavy.

Conclusion

I can’t wait to have my first ride in a hydrogen-powered double-decker bus.
