Cummins To Build H2 Fuel Cell Innovation Center In West Sacramento

The title of this post, is the same as that of this article on Hydrogen Fuel News.

Cummins are one of the companies with a lot to lose, if they don’t replace their diesel products with a zero-carbon alternative.

They took over Hydrogenics and now they seem to be putting money into improving and developing hydrogen fuel cells and probably all the other gubbins to make them work.

I have worked as a consultant for the company and they are very happy to tailor their products to a customer’s needs.

This philosophy would work well with hydrogen-powered vehicles and stationary applications.

I wouldn’t be surprised to see Cummins grow to one of the largest companies in the field of hydrogen.

  1. Well seeing as the fuel cell stack for the Alstom iLint is Hydrogenics, it might be fair to assume they use same arrangement in the Aventras.

    • Fair point!

      When I was working with Cummins at Darlington on analysing faults, the engineer I worked with outlined their philosophy on small diesels. Say you wanted a diesel of a particular power and it was needed to go in a particular space, Cummins would rearrange the accessories and gubbins to fit your application. They didn’t seem to mind, if some applications didn’t sell large numbers of engines.

      I do wonder, whether this philosophy got them the order for the Routemaster buses, as that might be a challenging application. But they seem to have worked, as you don’t see London’s street littered with dead Routemasters, with diesel engine failures.

      Surely, a similar philosophy would work with hydrogen.

      In the case of the Routemaster, Cummins might even be able to provide a conversion kit to hydrogen. There must be millions of installations like that for diesel engine manufacturers.

      • I think the question you ask about Cummins has to be considered in the light of the infographic of the Wright Bus

  2. The Routemaster has gubbins everywhere, just like this bus.

    • Here’s the arrangement of the engine, electric driveline as installed on the Wrightbus Routemaster. If you compare the space under the stairs which is used for the existing set up with the fuel cell equipped bus you see that the ‘gubbins’ takes up a lot more more room at the back of the bus. Also you need an electric air compressor for the brakes and suspension that you originally had fitted to the engine.
