Hydrogen trains lined up for 2021 start in UK

Comment

My understanding is that the most often used technology for producing hydrogen involves steam reform of methane. Methane is a fossil fuel, but that shouldn't be confused with the production of greenhouse gases. However, I'm told that CO2 is a byproduct of the process and steam production obviously requires an energy input from somewhere. While the carbon footprint might possibly be reduced, the main purpose of using fuel cells here is to reduce the sort of health-threatening emissions that are commonplace with diesel units. I personally have had a dreadful experience at Birmingham New Street, waiting for a delayed local train while a diesel unit on the opposite track belched out fumes over several hundred passengers. Not that we are likely to see these trains at Birmingham, as they seem to be aimed at northern routes.
