Re: Hydrogen locomotive more details

The problem with hydrogen is twofold:

1. It is very inefficient to produce by electrolysis relative to refining crude oil or liquifying coal/biomass. Be cheaper to string wires over the rails than it would be using that electricity to convert water into hydrogen.

2. Liquid hydrogen needs 4 times the amount of tank space as diesel fuel per unit of useful work performed.

As for NOx and CO2 emissions, since railroads are an irrelevant source of pollution (real or perceived), any change in emissions from CO2 to NOx has near zero impact. "Clean burning" locomotives are a waste of resources, which I guess guts the gist of having a hydrogen burning locomotive in the first place........
