Caterpillar, Cummins Move On Hydrogen For Trains

The title of this post, is the same as that of this article on Construction Equipment.

This is the first paragraph.

Caterpillar and Cummins are working separately to put hydrogen to work in locomotives.

They have a lot to lose with the extinction of their diesel businesses, so why not join the party.

  1. The article could have equally said that Caterpillar and Cummins have separate collaboration agreements with Chevron to develop the use of hydrogen for transport applications.
    Looking behind this story is the fact that Chevron have belatedly discovered what Shell, BP, Total, ENI and Repsol have been pursuing for the last few years – the need to be engaged in the hydrogen market. I have to say that Chevron still don’t get it. They seem to think their investment in blue hydrogen processes is “green”.
    Anyway hope Cummins and Caterpillar are successful, there’s still a lot to be said for the internal combustion engine.

  2. I am not one of those people who thinks that blue hydrogen is a massive aberration.

    I had lots of discussions at ICI with Senior Chemical Engineers in the early 1970s.

    They felt that only three things should come out of a large scale chemical works.

    Product that customers purchase.

    Pure water that can be safely returned to a watercourse.

    Pure air that could be breathed.

    All those years ago, carbon dioxide was probably discharged.

    I suspect now, the aim would be to get a continuous stream of carbon dioxide in a pipe, that could either be stored or used.

    Uses at the moment are not large in number, but as carbon can be used to create structure, I am sure the number of uses will increase.

    Knowing chemical process engineers as I do, I’m sure we’ll see chemical plants and blue hydrogen plants producing streams of pure carbon dioxide, that can be turned into something useful and sold.

  3. I think a large pipe goes from a Billingham fertiliser factory to a Quorn factory and a very large tomato greenhouse. Unfortunately, I can’t find it on the map.

    How do you feel about that?

    Apparently, Scottish soft fruit grown near distilleries have used the carbon dioxide given off in distilling to grow big and strong.
