They are talking about fuel cell technology the same as used on the space shuttle and international space station. Store hydrgen and oxygen in seperate containers. Mix and you get get energy and water. The electricy produced will be used to power the train. NO diesel spewing fumes all over the place.
BNSF has jumped on to be the testing Railroad

As mentioned in my other thread:

Marine looks like it would be the primary market and there are already Marine Hydrogen powered tugs in the works

The Marine version of the 710 is Tier 4 certified using after treatment.
I don't know enough about using Hydrogen as a Diesel replacement to have an opinion. I saw that in some of those tugs, there's support for a Diesel/Hydrogen blend as well as a pure hydrogen solution.
For the railroad application, I'm not sure what the implications are. Where is it stored? What added equipment to use it?
Is the 2 stroke 710 a better platform for Hydrogen than a 4 stroke diesel?
