What sort of ranges would you be looking to do on hydrogen?

Merseyrail around, and under, Liverpool is also 3rd rail. Another fact is that 70% of all train journeys are on electrified track - the busy parts. Also, there was supposed to be a trial of a hydrogen train on the Liverpool to Chester line via Runcorn. It would run past the Alstom facility just outside Liverpool, with hydrogen supplied from the nearby Stanlow refinery. Is this going ahead? Merseyrail this year is also trialling battery trains that run on the 3rd rail and then onto unelectrified track. Two route extensions are marked, from Liverpool to Preston on unelectrified track from Ormskirk to Preston. The other is from Liverpool to Helsby, running on unelectrified track from Ellesmere Port to Helsby. Hydrogen is precluded as the trains have to run in the underground tunnels and stations of Liverpool and Birkenhead. It seems hydrogen trains will be for open track only.

What about the cost of procuring the materials for the membranes?

Love to see ou Stuart

Why not burn hydrogen in a combustion engine as opposed to a fuel cell?

otsys77 It would have anout 30% efficiency and I’ve heard claims it could also produce NOx, the same chemical as it is in gasoline engines. Maybe it’s because you don’t get to use pure oxygen, but instead a mixture of gases which is the air, with it’s roughly 70% nitrogen component
